Description

Every time when I add Database step before another Database step, the Invoke SQL is predefined according to the existing Database step.

When I want to create DB step for Invoke SQL, and I have already defined another Invoke SQL step which is before that step, the SQL statement is automatically predefined and it is same as SQL statement in the step which was defined before.

When I add another step between them, e.g. log step, the SQL statement is empty.
