Applies to: SQL Server SSIS Integration Runtime in Azure Data Factory

Applies to: SQL Server

Starts an instance of execution in the Integration Services catalog.

Syntax

catalog.start_execution [ @execution_id = ] execution_id [, [ @retry_count = ] retry_count]

Arguments

[@execution_id =] execution_id
The unique identifier for the instance of execution. The execution_id is bigint.

[@retry_count =] retry_count
The retry count if the execution fails. It takes effect only if the execution is in Scale Out. This parameter is optional. If not specified, its value is set to 0. The retry_count is int.

Remarks

An execution is used to specify the parameter values that is used by a package during a single instance of package execution. After an instance of execution has been created, before it has been started, the corresponding project might be redeployed. In this case, the instance of execution references a project that is outdated. This invalid reference causes the stored procedure to fail.

Note

Executions can only be started once. To start an instance of execution, it must be in the created state (a value of 1 in the status column of the catalog.operations view).

Example

The following example calls catalog.create_execution to create an instance of execution for the Child1.dtsx package. Integration Services Project1 contains the package. The example calls catalog.set_execution_parameter_value to set values for the Parameter1, Parameter2, and LOGGING_LEVEL parameters. The example calls catalog.start_execution to start an instance of execution.

Declare @execution_id bigint  
EXEC [SSISDB].[catalog].[create_execution] @package_name=N'Child1.dtsx', @execution_id=@execution_id OUTPUT, @folder_name=N'TestDeply4', @project_name=N'Integration Services Project1', @use32bitruntime=False, @reference_id=Null  
Select @execution_id  
DECLARE @var0 sql_variant = N'Child1.dtsx'  
EXEC [SSISDB].[catalog].[set_execution_parameter_value] @execution_id, @object_type=20, @parameter_name=N'Parameter1', @parameter_value=@var0  
DECLARE @var1 sql_variant = N'Child2.dtsx'  
EXEC [SSISDB].[catalog].[set_execution_parameter_value] @execution_id, @object_type=20, @parameter_name=N'Parameter2', @parameter_value=@var1  
DECLARE @var2 smallint = 1  
EXEC [SSISDB].[catalog].[set_execution_parameter_value] @execution_id, @object_type=50, @parameter_name=N'LOGGING_LEVEL', @parameter_value=@var2  
EXEC [SSISDB].[catalog].[start_execution] @execution_id  
GO

Return Code Value

0 (success)

Result Sets

None

The execution identifier is not valid
The execution has already been started, or it has already been completed; executions can be started only once
