Execute SQL Task in SSIS

The Execute SQL Task in SSIS is used to run SQL queries (statements) or stored procedures from the SSIS package. You can use this SSIS Execute SQL task to write the single SQL statement or multiple SQL statements that can run sequentially.

We can use this SSIS Execute SQL Task for the following purposes:

  • Create, Alter, and drop the tables and views.
  • Before we start inserting the data into the table, we can use this task to truncate tables or views
  • Recreating (drop and create) the dimension and fact tables before loading the data into them.
  • Run stored procedures.
  • Save the result set in a variable so that we can use that data in other tasks.

SSIS Execute SQL Task General Tab

This tab is used to configure the SSIS Execute SQL Task properties.

SSIS Execute SQL Task Options Tab

  • TimeOut (in seconds): Please specify the connection timeout in seconds. If the connection takes more than that time, then the connection will fail. By default, it is 0, and it means infinity seconds.
  • CodePage: Please specify the code page that the task wants to use while converting the Unicode values in variables. By default, it will use the local computer code page.
  • Type Conversion Mode: By default, it is Allowed, and it means the execute SQL task will attempt to convert the query results and output parameters to data types of the variable

SQL Source Type

Please specify, How you want to provide your source data. This SSIS Execute SQL Task provides three options.

  • Direct Input: If you want to write an SQL Statement directly, then select this option.
  • File Connection: If your SQL Query is in the file system, then please select this option
  • Variable: If your query is in a variable, please choose this option.

The next property completely based on the SQL Source Type option. For example, if we select the File system as the source type, the following property will change to File Connection. And we can use this property to locate the select the file.

Execute SQL Task in SSIS 7

For example, if we select the Direct input as the source type, the next property will be changed to SQL Statement. And we can use this property to write the SQL statement. To demonstrate, we are writing the following query.

SELECT [Id]
      ,[FirstName]
      ,[LastName]
      ,[Education]
      ,[Occupation]
      ,[YearlyIncome]
      ,[Sales]
      ,[HireDate]
FROM [SQL Tutorial].[dbo].[Employee Table]
WHERE [Sales]  > ?

IsQueryStoredProcedure

If you selected the Connection type as ADO or ADO.NET, then only the property value is enabled. If your query is a stored procedure, change the property value to True.

Result Set

This SSIS Execute SQL Task property helps us to configure the output. It has four properties:

  • None: If you don’t want to return anything, select this option. For example, you are using the Execute SQL Task to truncate the table. Then there is no point in returning any value.
  • Single Row: If you want to return a single row as the result set, then you can use this option — for example, the total number of records in a table, or columns, etc.
  • Full Result Set: If you want to return more than a single row as the result set, then you can use this option.
  • XML: If you want to return the XML file as the result set, you can use this option.
