Are you sure you want to delete the saved search? If you choose "Execute only once" or "Execute periodically", one SQL CodeBehind file named [Input Alias].snapshot.sql is generated in the project under the Input.json file node. You can not create cross database references (foreign key relation), that's not supported. The delta query must return the same columns as the snapshot query, as well as the column operation. While such structures demonstrate that the designer understands abstraction (or, at least how to generalize and abstract things such as valid value lists), it negates any possible usage of DBMS-supported referential integrity.
