Saving DTS Packages in Visual Basic

SQL Server 2000

Saving DTS Packages in Visual Basic

When you use the Package2 object methods, you can save or load a package in the formats available to you through Data Transformation Services (DTS) Designer and the DTS Import/Export Wizard. You can save packages to Microsoft® SQL Server™ 2000, to SQL Server 2000 Meta Data Services and to a COM-structured storage file.

To save a package, use one of the following Package2 methods:

  • SaveToSQLServer

  • SaveToSQLServerAs

  • SaveToRepository

  • SaveToRepositoryAs

  • SaveToStorageFile

  • SaveToStorageFileAs

If the package is run before being saved, call the UnInitialize method first.

To load a package, first create the Package2 object and then invoke one of the following Package2 object methods:

  • LoadFromSQLServer

  • LoadFromRepository

  • LoadFromStorageFile

To delete a package from SQL Server or Meta Data Services, use the Package2 object RemoveFromSQLServer or RemoveFromRepository methods.

Example

The following code example shows a function loading a package in one format and saving it in another:

Enum eDTSPkgFormat
    REPOSITORY
    SQL_SERVER
    STORAGE_FILE
End Enum
