Get Rows from Result

Parent article

This step returns rows that were previously generated by another transformation in a job. The rows were passed on to this step using either the Copy rows to result step or the Transformation Executor step. You can enter the metadata of the fields you are expecting from the previous transformation in a job.

NoteThis step produces one or more rows and cannot be placed within a stream. It must be the first step in a stream since it produces rows. If you want to add this data to an existing stream, you need to use a join step.


  • Step Name: Specifies the unique name of the Get Rows from Result transformation step on the canvas. You can customize the name or leave it as the default.
