According to the standard EXEC SQL EXECUTE IMMEDIATE dynamically
prepares and executes a statement. ECPG used to just simulate this by
simply executing the statement. But before rewriting this I wonder if it
makes any sense at all. Where's the advantage of preparing a statement,
then executing it and then of course deallocating it again over a simple
execution?

The EXEC SQL EXECUTE IMMEDIATE clause is needed to be able to
dynamically compute the statement to be executed, but do we really need
to prepare it?
