Passing Variables to and from an SSIS task

In which Patrick Index casts a jaundiced eye on SSIS, and decides that, for all its faults, it has a number of uses as an ETL tool. In the first of a series of articles 'from the trenches', Patrick describes how to pass variables to, and from, an SSIS task.

Like it? SSISht!

Like it or loathe it, SSIS is here to stay.  I suppose it’s nice and graphical, and it is also aesthetically  pleasing when you finally get a screen full of green tasks – I tend to leave my screen displaying for a while when this happens, so that everyone can see it whilst I go and make a coffee. SSIS is much richer than DTS .  Additionally you quite often see jobs for SSIS specialists; it would seem that companies are using it as their de-facto ETL tool, standing apart from SQL Server.

SSIS is, by its very nature, frustrating to work with because it is a mish-mash of dissimilar development environments, and I don’t find that the syntax is always intuitive.

There doesn’t seem to be a great deal of material on the web and it can be hard to find good examples to use as guidelines.  So, in the spirit of building up a knowledge base, and hopefully persuading Tony to set up a dedicated section on Simple-Talk for SSIS, I have constructed an example to demonstrate passing variables into and out of an ‘ Execute SQL Task and Script Task’ .

Passing Variables to and from an ‘Execute SQL Task and Script Task’.

The two tasks do fundamentally the same thing, which is to try and date-stamp a file.  The final variable value “ FullPath ” could then be easily used by a File System Task to copy/move or delete a file perhaps.

I suppose most SQL Server developers would be more comfortable knocking up this fairly trivial code in SQL, but the difficulty is in passing and catching the input variables in the task.   This example demonstrates the problem.

I have set up a package with three String variables called

  • FileName, which has a data type of String and an initial value of “Import.txt”
  • FolderName, which has a data type of String and an initial value of “c:\”
  • FullPath, which has a data type of String and no initial value

… and an ‘ Execute SQL Task and a Script’   Task.

The package is called, rather imaginatively, “Package3”. The scope of the variables is at the package level.  One thing to note when you set up variables (choose SSIS-VARIABLES from the top menu) is to make sure you have clicked on the package and not a task when you create or add a variable.  If you create a variable while being clicked on a task (therefore with task scope) then the variable will disappear from the list when you click up to the package.  Sorry to be an old dog but I initially found this a bit confusing.

The simplest way to inspect your variables is to set a break-point on the task (right click on the task and choose EDIT BREAKPOINTS) for the OnPostExecute event of the task.  This will then allow you to  inspect the value of the variable after the task has completed its execution.  The red dots on the tasks indicate that there are already breakpoints set up on the task.

544-image002.jpg

Doing it the ‘Execute SQL Task’ way

In the ‘Execute SQL Task Editor’ in the ‘Parameter Mapping’ section, (double-click on the task and choose Parameter mapping), I have set it up so that the two variables i.e. User::FolderName and User::FileName are added to the dialogue box.  Each has a Direction of “Input” which seems logical and a data type of VARCHAR.  The parameter names that I have used are just the ordinal positions of 0 and 1, which is what the context help suggests.  In other words, the value of User::FolderName is the first input parameter and User::FileName is the second input parameter.  The parameter lengths are 50. In other words, we are dealing with a varchar(50) parameter.  The initial default values for these, when you set them up, are -1 which tells me nothing I am afraid.

544-image004.jpg

For the Result Set options on the Execute SQL Task, I have put in the aliased name of the output column from my query, which, giving my poetic instincts full rein, I have called FullPathFromQuery , and I want to pass this to my variable User::FullPath .

544-image006.jpg

‘So what about the query?’ you may ask.  Well, if we go back to the General option on the Execute SQL Task Editor, you can see the code and I will list it again here

For such trivial code you would not want to set up a stored procedure I suspect, so the option of passing parameters to a stored procedure is not really there.

The only way to pick up these input variable values is to use question marks “?” in the order that they are passed.  This query as it stands will clearly not parse in query analyser window so you can only really test your code by running it in the task: This is not ideal.

You must also set the ResultSet option to be “Single row”.

544-image008.jpg

If you run this to the break point one can see that the variable User::FullPath has been assigned the value  C:\\Import_200870805.txt ( I ran this on 6th Aug  2008) so the code must be working.

544-image010.jpg

Using a Script Task instead

Perhaps a simpler way to do this is just to use the Script Task.  The trivial code again demonstrates how to pick up and assign values to and from variables in the vb.net code.  You need to tell the task which variables it is going to use by adding them to the ReadOnlyVariables  and ReadWriteVariables options in the Script Task editor window and also be aware that the variables names are case-sensitive.

544-image012.jpg

The code which shows the passing and assignment of the variables in the script is shown below.

If you put a breakpoint on the task the value of the variable can be inspected to give tomorrows date, and it should look like this…

544-image014.jpg

So which approach is best? 

People tell me that using question marks was how it was in DTS, but I have to say I didn’t find setting up the Execute SQL Task particularly intuitive.  The script task for me seems like the simplest solution of the two, surprisingly.

So the example is not going to win a Nobel Peace Prize for complexity but it does demonstrate the awkwardness of SSIS in the real world.  Hopefully the article will encourage readers to publish their experiences using the various tasks and we can build up a knowledge base of real world examples for everyone to reference on the simple-talk site.  I have recently been wrestling with the XML task and data source which will be the subject of my next article.

sql task with parameter mapping ssis

Patrick Index

I have been contracting for 14 years and before that I worked for a software house for 5 years in the late 80's. I started out as a Lotus 1-2-3 developer and then did database development with Paradox. That soon became Access development which progressed to Access with SQL Server in a client server scenario and now I suppose I would describe myself as a SQL Server developer.

Execute SQL Task in SSIS: SqlStatementSource Expressions vs Variable Source Types

In this article, I will give an overview of Execute SQL Task in SSIS and I will try to illustrate some of the differences between writing an expression to evaluate SqlStatementSource property or writing this expression within a variable and change the Execute SQL Task Source Type to a variable.

This article is the fourth article in the SSIS feature face to face series which aims to remove confusion and to illustrate some of the differences between similar features provided by SQL Server Integration Services.

Execute SQL Task

From the SSIS toolbox item description, Execute SQL Task in SSIS is used to execute SQL statements or stored procedures in a relational database.

This image shows the Execute SQL Task in SSIS descripton from the toolbox

Figure 1 – Execute SQL Task description

The SQL statement can be a:

  • Single SQL Command
  • Multiple SQL Commands
  • Stored procedure

This shows the Execute SQL Task in SSIS icon when added to the package control flow.

Figure 2 – Execute SQL Task in SSIS

This Task need a connection manager to establish a connection with a data source and it supports several data sources other than SQL Server since it can use the following connection managers:

  • Excel: An Excel connection manager enables a package to connect to a Microsoft Excel workbook file
  • OLE DB: An OLE DB connection manager enables a package to connect to a data source by using an OLE DB provider
  • ODBC: An ODBC connection manager enables a package to connect to a variety of database management systems using the Open Database Connectivity specification (ODBC)
  • ADO: An ADO connection manager enables a package to connect to ActiveX Data Objects (ADO) objects, such as a recordset
  • ADO.NET: An ADO.NET connection manager enables a package to access data sources by using a .NET provider
  • SQL Compact (SQLMobile): A SQL Server Compact connection manager enables a package to connect to a SQL Server Compact database

Note that the SQL Statements syntax differs based on the data source provider, as example you have to write T-SQL when data source is SQL Server. But when it is Excel or Access, SQL commands have to be supported by Microsoft.Jet.OLEDB and Microsoft.ACE.OLEDB providers.

Is Excel a relational database?

As mentioned above, Execute SQL Task in SSIS is used to execute SQL statements on a relational database, while Microsoft Excel is not a database engine. Because Excel is widely used to store data, and many users want to retrieve data using SQL Statements, Microsoft has given the ability to query tabular data stored in Excel and text file using Jet and ACE OLE DB providers, which pretend that Excel is a relational database and tries to force some data integrity rules while reading, i.e. forcing a single data type for each column by only reading a dominant data type and converting all other values to NULL.

Execute SQL Task configuration

As shown in the image below, the Execute SQL Task in SSIS has many options that can be configured. This article will only focus on the SQL Statement configuration. If you need more details on other options, you can refer to the official documentation .

This image shows the Execute SQL Task in SSIS editor form

Figure 3 – Execute SQL Task editor

There are different methods to define the SQL Statement that we need to execute. You can select the method in the SQLSourceType property:

  • Direct Input: You can write the SQL Statement manually in SQLStatement property; it can be a simple query or you can just enter a stored procedure name and change the IsQueryStoredProcedure property to True
  • File Connection: You can select a text file or .sql file that contains an SQL Statement using a File Connection manager
  • Variable: You can select a variable that contains an SQL Statement; when changing the SQLSourceType property to Variable, a new property appears in the editor which is SourceVariable

Another method to set the SQL Statement is by using expressions, you can go to the Expression Tab, and select the SQLStatementSource property to write an expression. To learn more about writing expressions in SSIS, you can refer to the official documentation: Integration Services (SSIS) Expressions .

SqlStatementSource expression vs Variable Source Type

Many times I was asked on the difference between writing the SQL Statement within a variable and use it as a Source or using expressions to define the SQL Statement. And if one approach is more recommended.

In this section, I will first mention each method description from the official documentation of Execute SQL Task in SSIS, then I will try to clarify more based on my experience.

This image shows the how to assign an expression to SqlStatementSource property of the Execute SQL Task in SSIS

Figure 4 – SQLStatementSource expression

Official Documentation

Referring to the official documentation of Execute SQL Task in SSIS :

  • Variable Source: Set the source to a variable that defines the Transact-SQL statement. Selecting this value displays the dynamic option, SourceVariable
  • SqlStatementSource expression: When you use an OLE DB connection manager, you cannot use parameterized subqueries because the Execute SQL Task in SSIS cannot derive parameter information through the OLE DB provider. However, you can use an expression to concatenate the parameter values into the query string and to set the SqlStatementSource property of the task

After mentioning each approach description, and based on my experience, I can say that there is no better approach, each one has its own use case.

As mentioned above using expression is needed if the SQL Command is built based on other variables, such as passing the table name dynamically, or passing parameter because  Execute SQL Task in SSIS doesn’t support dynamic queries such as :

The first approach can be used if the developer decided to store the whole SQL Command inside a variable even if the variable is evaluated as an expression.

In case that variable is evaluated as an expression, there is no difference between both approaches from the SQL command perspective, but it may differ in case that the statement is used multiple times within the package. As an example of the query mentioned above, if the table name is variable and this query needs to be executed at different steps within the package, evaluating the variable as an expression is more efficient than writing the expression multiple times. Also, using a variable may facilitate the debugging process since it can be easily monitored.

In addition, as I remember, in the old SSIS versions, the variable source option was not available and it was added later (I think in 2012) version to facilitate the developer work in case the whole SQL command is stored inside a variable rather than adding one variable expression in SQLStatementSource, as an example if the query is built within a Script Task and stored in a variable.

In the end, it is up to you to decide which approach you feel more comfortable with based on what we have mentioned.

Getting Started with SQL Server Integration Services SSIS Parameters vs. Variables

By: Daniel Calbimonte   |   Comments   |   Related: More > Integration Services Configuration Options

I noticed that in SQL Server 2012 and later versions it is possible to create SQL Server Integration Services (SSIS) parameters. What are SSIS parameters and how are they used?

SSIS parameters are a feature introduced in SQL Server 2012. You can now pass values at a project level and at a package level. In the past, we used package configurations to store values in XML files or environment variables. Now we can use parameters to store our information.

Requirements

  • SQL Server Relational Database Engine installed
  • SQL Server Integration Services installed
  • SQL Server Data Tools Installed (SSDT) or BIDS (Business Intelligence Development Studio) installed
  • You can use SQL Server 2012 or later versions. In this example, we are using SQL Server 2014
  • A SQL Server table and a CSV file for data

SQL Server Integration Services Project Parameters

Project Parameters are scoped at the project level and can be used across several packages.  Here is an example of using a Project Parameter.

  • Imagine that you have several SSIS packages in a project and you want to configure the same values in all the packages at the same time. With variables, your scope is the package, however with Project Parameters you can use the same parameter in all the packages. In this example, we will show how to read values from a project parameter. We will import a specified number of rows from a CSV file to a SQL Server table.

File Sysem Task

  • In the Solution Explorer, double click on Project.params:

Solution Explorer parameters

  • You can create parameters in the same way that you create a variable. It requires a Name, a Data Type and a Value. The Sensitive property is used to store sensitive data. When this value is set, the data is encrypted. The Required property is used when the value is required before executing the package. Finally, you can add a description for the parameter. We will set the value to 70:

Project parameters in SSIS

  • In the packages we will copy a specified number of rows from a CSV file. We will use the Bulk Insert Task to copy data from a CSV file to an Excel file.

Bulk insert Task

  • Double click on the Bulk Insert Task and create a connection to a SQL Server table as a destination table. In the column delimiter, select comma. In the file, select a CSV file with the data to import to the SQL Server table:

Bulk insert properties

  • In the Expressions page, click the browse button:

Browse button to edit expressions

  • Select the LastRow property and in Expressions click the browse button:

SSIS Expression editor

  • Expand the Variables and Parameters Tree and drag and drop the Parameter created in step 3:

Project parameter expression

  • Once you accept the expression, you will receive an error message that say "Cannot convert System.Int32 to System.Int64":

Error message

  • To convert to System.Int64, expand the Type Casts folder and drag and drop DT_I8. What we did is specify the number of rows to be equal to the project parameter named NumberOfRows. We specified the lastrow property to the value of 70 that was set above.

Converting the SSIS datatype

  • Run the package:

Executing the package

  • If you want you can check the number of rows in the SQL Server destination table:

The destination table

  • As you can see, 70 rows were imported (the value specified in step 3). We imported 70 rows from the CSV file with the value read from the project parameter.

Table displayed

SQL Server Integration Services Package Parameters

Package Parameters are scoped at the package level.  Here is an example of using a Package Parameter.

  • In this new example, we will create a parameter with a T-SQL command and pass the parameter value to the Execute SQL Task. To do this in an SSIS package, go to the Parameters page and create a new package. We will create a package parameter named query. The Data Type will be string and the value will be a T-SQL Backup command:

Parameters tab

  • Drag and drop the Execute SQL Task.

Execute SQL Task

  • Double click the Execute SQL Task and add a connection to SQL Server. In the SQLSourceType, select Variable. In the SourceVariable, select the query package parameter.

Execute SQL Task properties

  • Run the package.

Execute SQL Task

  • If everything is OK, a backup will be created. What we did is pass the parameter value created in step 1 as the command.

Backup created

In this new tip, we learned how to use the Project Parameters and the Package Parameters. The Project Parameter can be used in multiple packages, where as the Package Parameter only works at the package scope. Project Parameters are replacing configuration files used in the past to store global configuration values.  The parameters do not support expressions as values for variables. The parameter values are read-only during the execution of the package, they cannot be changed dynamically.

SSIS Execute SQL Task : Mapping Parameters And Result Sets

Arie D. Jones

Arie D. Jones

A very common scenario in an ETL process is one in which you need to call out to some configuration tables to figure out some values that it needs to use somewhere downstream in the process. Quite often you also want to pass in some parameters as well. So in this article I will be addressing both of those scenarios. To start, you will just need to drop an Execute SQL Task item onto the Control Flow of an SSIS package and set up the initial configuration so that it is basically given a connection string

image

Now we want to enter in our SQL statement that will contain the parameters. In this case we are using a SQL Server connection and I will be calling a stored procedure. So I will provide ?s for each of the parameters involved. So my statement look like this…

exec Staging.usp_GetTicketQueries ?,?,?

I could also be more verbose if I wanted to

exec Staging.usp_GetTicketQueries  @StartDate=?,@EndDate=?,@SomeOtherValue=?

but it isn’t entirely necessary. Now that I have the statement ready I just need to click on the Parameter Mapping menu item on the left hand side and map my parameters.

image

Notice that there isn’t anything really tricky here. I line out the variables that will be used with the appropriate type and size. The only part that trips a lot of people up is the fourth one which is the Parameter Name. When you initially add an additional parameter to map this column will have a text name in it. Instead what I have done is to change these so that instead it has the 0 based index of the parameters in my statement. Once you have them mapped to the proper index value then everything should be golden.

Now we want to grab that result set that is being sent from the stored proc and map its values to some different variables. So we need to go back to the General settings screen and in the “Result Set” section change the value of the ResultSet property to something other than None in order to be able to make changes to the ResultSet screen later. In this case, I am just returning a single row. So I merely change the value to Single row and I am ready to map the result set.

image

Now switch to the Result Set screen via the menu on the left. Here what you will want to do is to map the actual column names of the result set to the variables that you want them to be placed into. Pretty simple. In the end, you will have something that looks like this.

image

Now you can click OK as you are finished with the process. This is actually a fairly handy thing to know in order to make your ETL processes a little more dynamic.

Execute SQL Task in SSIS

Updated: Aug 19, 2021

Example 1: Execute SQL Task, Result set: Sigle row, using dynamic query

Example 2: Execute SQL Task, Result set: Full result set

Example 3: Execute SQL Task, SQLStatement as a Expression

Execute SQL Task in SSIS allows user to execute parameterized SQL statement and create mapping between these parameters and the SSIS variables. To add a parameter into a SQL statement you must use a parameter marker which differs based on the connection type.

Connection Type Marker Example

ADO,ODBC,OLEDB ? Select * from table where ID > ?

ADO.NET, SQLMOBILE @<parameter name> Select * from table where ID > @ID

EXCEL ? Select * from table where ID > ?

There are three types of parameters that can be used within an Execute SQL Task in SSIS:

Input parameters: to pass a value as a parameter within a SQL command or stored procedure

Output parameters: to store a value generated from an SQL command or stored procedure

Return Value: to store a value returned by an SQL command or stored procedure

As a example the following SQL command:

select * from dbo.Products where CategoryID = ?

When using SQL query with a parameter you must go to the Parameter Mapping tab and define the variable mapping.

create the variable

map the variable comming from SQL Server

sql task with parameter mapping ssis

Properties of parameter

Variable Name: Select the variable name that you want to map to a parameter

Direction: Specify if the type of the parameter (input, output, return value)

Data Type: Specify the data type of the parameter (It must be compatible with the data type of the variable)

Parameter Name: The name of the parameter, the naming convention depends on the connection type

Parameter Size: Specify the length of the parameter when using string data types otherwise it must be -1 (default value)

Parameter Name

Connection type Parameter name

ADO Param1, Param2, …

ADO.NET and SQLMOBILE @<parameter name>

ODBC 1, 2, 3, …

EXCEL and OLE DB 0, 1, 2, 3, …

Output parameter

When it comes to output parameters, they are used to store values that can be set at any part of the SQL command, they have the same concept of the stored procedure output parameters. As example, if we can use a similar SQL command to store the Maximum value of CategoryID column:

Select ? = Max(CategoryID) from dbo.Products

sql task with parameter mapping ssis

Result Sets

When using an Execute SQL Task in SSIS, result sets can be generated from an SQL command mostly a SELECT query. There are 4 types of result sets:

None: No result set is generated

Single Row: When the result set is a single row, such as SELECT TOP 1 or a SELECT MAX() commands

Full Result set: When the SQL statement generates multiple rows such as a SELECT * command

XML: This option is used to store the result within an XML value

You can select the result set type from the Execute SQL Task editor (General Tab):

sql task with parameter mapping ssis

To store the result set into a variable, we must configure the variable mapping within the Result Set tab.

sql task with parameter mapping ssis

Variable data type

When using Single Row result set or XML string, values are stored within variable and can be consumed directly within Expressions, Tasks, Scripts or Transformations. But, when the result set is stored within a variable of type System.Object , the variable can be consumed using:

ADO enumerator within a Foreach Loop container: This option is used to loop over the rows of the result set and consume them row by row by mapping each row columns with SSIS variables

Using a .Net Script (Task / Component): The code differs based on the Object type

Execute SQL Task, Result set: Sigle row

SQLSourceType: variable (dynamic query)

sql task with parameter mapping ssis

Step 1: Define variables

vValueReturnedBack : Execute SQL Task will return UnitPrice value from SQL server - Result set: Single Row. I will map this variable to Result set variable in Execute SQL Task.

vSQLCommand : this variable is for building the dynamic SQL code.

vWhereCondition : contains value[6] in the where clase

vTable : holding SQL table name [Products]

vColumnName : column I want to retrieve from table products.

sql task with parameter mapping ssis

Step 2: use Expression Builder to build the dynamic SQL statement.

@[User::vSQLCommand]="Select " + @[User::vColumnName]+" From " + @[User::vTable] +" Where ProductID = " + @[User::vWhereCondition]

sql task with parameter mapping ssis

step 3: Add Execute SQL Task and set it up.

Result Set: Single row; SQLSourceType: Variable; SourceVariable: vSQLCommand ...

sql task with parameter mapping ssis

Step 4 :Because the result set is NOT none but Single row, I have to set up the variable for Result set. I do not work with parameters from SQL [?] so there is no parameter mapping needed.

From SQL server, I will get back UnitPrice: 25 and vValueReturnedBack will hold this value.

sql task with parameter mapping ssis

Step 5: Run the package

sql task with parameter mapping ssis

Execute SQL Task, Result set: Full result set

I want to place this result set into a variable.

sql task with parameter mapping ssis

Step 1 : Prepare the variables which will represent the columns from SQL table and variable to hold the returned table (data type Object) from sql server.

sql task with parameter mapping ssis

Step 2: set up Execute SQL Task

Result set: Full result set

SQLSourceTyp: Direct query

SQLStatement:

Select TOP(10) [CategoryID], [CategoryName], [ProductName], [ProductSales] from [Sales by Category]

order by ProductSales desc

sql task with parameter mapping ssis

Step 3: Go to Result Set , SQL statement returns Full result set which must be mapped to the variable type Object.

sql task with parameter mapping ssis

Step 4: I am going to add Foreach loop Container just to watch the variables.

I need Foreach ADO Enum and an Object variable @vtblProductSales

sql task with parameter mapping ssis

Step 5: Variable Mapping. Must be in the same order as the SQL statement has been written.

sql task with parameter mapping ssis

Step 6: Run the package

Using dynamic query

I have set up a Data Flow which is loading data from a flat file into SQL server table. Using Row Count transformation which will return a number of rows loaded and require a variable for that @vCount.

sql task with parameter mapping ssis

On the Control Flow tab I have an Execute SQL task which will insert data into a SQL table. I am going to use an expression to build a dynamic query for this.

a/ mark Execute SQL task, press F4

b/ go to Expressions, click on the dots [....]

c/use SqlStatementSource in the Property window

d/build an expression

System Variables

  • 8 contributors

SQL Server Integration Services provides a set of system variables that store information about the running package and its objects. These variables can be used in expressions and property expressions to customize packages, containers, tasks, and event handlers.

All variables-system and user-defined- can be used in the parameter bindings that the Execute SQL task uses to map variables to parameters.

System Variables for Packages

The following table describes the system variables that Integration Services provides for packages.

System Variables for Containers

The following table describes the system variables that Integration Services provides for the For Loop, Foreach Loop, and Sequence containers.

System Variables for Tasks

The following table describes the system variables that Integration Services provides for tasks.

System Variables for Event Handlers

The following table describes the system variables that Integration Services provides for event handlers. Not all variables are available to all event handlers.

System Variables in Parameter Bindings

It is frequently useful to save the values of system variables in tables when the package is run. For example, a package that dynamically creates a table and writes the GUID of the package execution instance that created the table in a table column.

If you use system variables to map to parameters in the SQL statement that an Execute SQL task uses, it is important that you set the data type of each parameter binding to the data type of the system variable. Otherwise, the values of system variables may be translated incorrectly. For example, if the ExecutionInstanceGUID system variable, which has the string data type and contains a string that represents the GUID of the executing instance of a package, is used in a parameter binding with the GUID data type, the GUID of the package instance will be translated incorrectly.

This rule applies to user-defined variables as well. But, whereas the data types of system variables cannot be changed and you have to tailor your use of these variables to fit the data types, user-defined are more flexible. The user-defined variables that are used in parameter bindings are usually defined with data types that are compatible with the data types of parameters to which they are mapped.
