SAP HANA View Definitions Display Expanded SQL

When working with SAP HANA views in Alation, you may observe that the View SQL and Dataflow Content display a query that differs from the original CREATE VIEW statement. This behavior occurs because SAP HANA stores a standardized format of SQL in its system catalog, which may vary from the original statement entered by the user. For example, if you created a view using SELECT *, the definition stored in SAP HANA will contain the expanded list of columns. As a result, the SQL shown in the View SQL section on the column catalog page and the Dataflow Content on the lineage page reflect the expanded format and not the original view definition you entered.

This is an expected behavior resulting from how SAP HANA manages and stores view definitions in its system catalog.
