Exporting Environment Variables out of the SSIS Catalog

,

Sometimes when you’ve created a SSIS catalog, along with folders, environments and environment variables, you want this content on another server. Unfortunately, you can only script out these objects in SSMS at the moment you’re creating them (thus right before you clikc ‘OK’ to confirm). Once the objects are created, you can no longer script them out using the GUI.

Luckily, there’s a whole slew of stored procedures and views in the catalog that allow us to extract information and use that information to re-create the objects. Here are two scripts that I found useful.

The first one extracts all environment variables out of an environment (I currently take only the data type String into account to put quotes around, but this might be expanded):

SELECT
    v.[name]
   ,v.[type]
   ,v.[value]
   ,Script = 'EXEC [SSISDB].[catalog].[create_environment_variable]
       @variable_name=''' + CONVERT(NVARCHAR(250), v.name) + '''
      ,@sensitive=0
      ,@description=''''
      ,@environment_name=''myenv''
      ,@folder_name=''myfolder''
      ,@value='
             + IIF(v.type = 'String'
                ,N'N''' + CONVERT(NVARCHAR(500), v.value) + ''''
                ,CONVERT(NVARCHAR(500), v.value)
                )
             + '
      ,@data_type=N''' + v.type + ''';
'
FROM    [SSISDB].[catalog].[environments]          e
JOIN [SSISDB].[catalog].[folders]               f ON f.[folder_id]      = e.[folder_id]
JOIN [SSISDB].[catalog].[environment_variables] v ON e.[environment_id] = v.[environment_id]
WHERE   f.[name] = N'myfolder'
    AND e.[name] = N'myenv';

It also creates a script for each environment variable. Just copy paste the column contents and execute it on the server where you wish to create the variables. Once the environment variables are created, you need to create a reference between the environment and the SSIS project. Then, you need to link each parameter with its corresponding environment variable. The following script extracts the info and again creates a SQL statement to create this reference. It assumes though the parameters and the environment variables have the same name (which seems kind of a best practice, right?):

SELECT -- v.[name], v.[type], v.[value]
    Script = 'EXEC [SSISDB].[catalog].[set_object_parameter_value]
        @object_type=20
      , @parameter_name=N''' + CONVERT(NVARCHAR(500), v.name) + '''
      , @object_name=N''SSIS''
      , @folder_name=N''myfolder''
      , @project_name=''SSIS''
      , @value_type=R
      , @parameter_value=N''' + CONVERT(NVARCHAR(500), v.name) + ''';
'
FROM [SSISDB].[catalog].[environments]          e
JOIN [SSISDB].[catalog].[folders]               f ON f.[folder_id]      = e.[folder_id]
JOIN [SSISDB].[catalog].[environment_variables] v ON e.[environment_id] = v.[environment_id]
WHERE   f.[name] = N'myfolder'
    AND e.[name] = N'myenv';

Creating a folder and the environment are easy enough to do manually. If you want to script those out as well, this article can get you started.
