Next, click the Edit Schema button to check the tFileOutputDelimited schema. Here, you can change the schema or columns based on your requirement. Mostly, the input columns (DBInput) will sync with the tFileOutputDelimited. If that is not the case, then close the schema window and click on the Sync columns button.
