But you change the parameters / host variables every time?

In this case I can only shoot wild assumptions - DECLARE is no executable program statement - it is "executed" at compile time.

Maybe it's that - the DECLARE is executed / optimized at compile time, whereas the SELECT-INTO is executed / optimized at runtime.

Normally I would assume, that all static SQL statements are optimized at compile time - whereas dynamic SQL is of course only handled at runtime.

As I said - wild assumptions - maybe Barbara or Birgitta can clarify that.
