[firebird-support] Dynamic SQL Error SQL error code = -104 CTE CTE_CP is not used in query
Why?? Why does that have to be a failure?? Why can't Firebird just ignore it?? Is there any switch to turn off this behaviour?? (I've got some immensely complicated query generation code which, it now appears, can occasionally include a common table expression in the query that isn't actually used anywhere. I've now got to fix that code to be extremely careful about *ex*cluding unneeded CTEs - it's currently aimed at being extremely careful to *in*clude CTEs that *are* needed.) -- Tim Ward ++ Visit http://www.firebirdsql.org and click the Documentation item on the main (top) menu.

It sounds like this should be a warning, and not an error. Mark
