I'm using Firebird-, and client IBExpert.
According to, i have
implemented following case query(here part of the query),
But same error msg is giving and not executing.

when MP.RoleID = -1 then 'All Users'
when MP.RoleID = -2 then 'Superuser'
when MP.RoleID = -3 then 'Unauthenticated Users'
else R.RoleName

I can't see any problem, but why not executing, any comment???
