Mapping output columns (DataStage®)

You can map columns to specify which columns are output by the Checksum stage.

About this task

Review the list of columns that are input to the stage and the columns that are generated by the stage. You can select columns from this list to build a list of columns to be output by the stage.

You can map all the columns in a single operation, or you can drag columns one at a time and drop each one onto an existing output column.

1. Double-click the stage to open the stage editor. On the Output tab, click Edit in the columns section.
2. Select one or more of the columns that you want to output from the stage.
3. In the Maps from input column column, click the edit icon and specify the column that you want to map to.
4. Click Apply and return.
