SSISDB6：使用数据分流

标签：

数据分流就是类似于数据流Path的Data Viewer，数据分流能够将数据导入一个file中，便于查看数据流中的数据。数据流分流必须通过代码来实现。

To add data taps, the instance of the execution must be in the created state (a value of 1 in the status column of the catalog.operations (SSISDB Database)view) . The state value changes once you run the execution.

Declare @execution_id bigint
EXEC [SSISDB].[catalog].[create_execution] 
    @package_name=N‘Package.dtsx‘, 
    @execution_id=@execution_id OUTPUT, 
    @folder_name=N‘Demo‘, 
    @project_name=N‘ISStudy‘, 
    @use32bitruntime=False, 
    @reference_id=1

Select @execution_id


DECLARE @var0 smallint = 1
EXEC [SSISDB].[catalog].[set_execution_parameter_value] 
        @execution_id,  
        @object_type=50, 
        @parameter_name=N‘LOGGING_LEVEL‘, 
        @parameter_value=@var0

exec SSISDB.catalog.add_data_tap
    @execution_id=@execution_id,
    @task_package_path=N‘\Package\Data Flow Task‘,
    @dataflow_path_id_string=N‘Paths[OLE DB Source.OLE DB Source Output]‘,
    @data_filename=N‘datatap.csv‘

EXEC [SSISDB].[catalog].[start_execution] @execution_id
GO

@data_filename：是存储数据分流的文件名称，文件路径是固定的，不能更改，通常在SQL Server按照目录的Folder中创建数据分流文件

@task_package_path：是Data Flow Task的 PackagePath 属性值

@dataflow_path_id_string：是Data Flow Path的 IdentificationString 属性值

参考文档：

catalog.add_data_tap

add_data_tap [ @execution_id = ] execution_id
[ @task_package_path = ] task_package_path
[ @dataflow_path_id_string = ] dataflow_path_id_string
[ @data_filename = ] data_filename
[ @max_rows = ] max_rows
[ @data_tap_id = ] data_tap_id
OUTPUT

[ @task_package_path = ] task_package_path              

The package path for the data flow task. The PackagePath property for the data flow task specifies the path. The path is case-sensitive. To locate the package path, in SQL Server Data Tools right-click the Data Flow task, and then click Properties. The PackagePath property appears in the Properties window.

The task_package_path is a nvarchar(max).

[ @dataflow_path_id_string = ] dataflow_path_id_string              

The identification string for the data flow path. A path connects two data flow components. The IdentificationString property for the path specifies the string.

To locate the identification string, in SQL Server Data Tools right-click the path between two data flow components and then click Properties. The IdentificationString property appears in the Properties window.

The dataflow_path_id_string is a nvarchar(4000).

[ @data_filename = ] data_filename              

The name of the file that stores the tapped data. If the data flow task executes inside a Foreach Loop or a For Loop container, separate files store tapped data for each iteration of the loop. Each file is prefixed with a number that corresponds to an iteration.

By default, the file is stored in the <drive>:\Program Files\Microsoft SQL Server\110\DTS\DataDumps folder.

The data_filename is a nvarchar(4000).
