Union

This article describes an example of creating and executing an ETL task with data union from different sources.

Three tables must be in the repository: T_SourceOne, T_SourceTwo and T_Destination. Tables must be identical in structure. The repository must also contain an ETL task with the ETLTASKS identifier. On executing the example presented below four objects are created in the ETL task: two repository sources, the Union transformer and repository consumer. The required properties and links are set for all objects:

After objects are created and saved, the ETL task is executed. The similar code applied to different objects is placed into separate procedures or functions.
