Actually I was talking about several fields, but to make it worst I really
do not know how many fields. So I was making a quoted set of strings to
put together at sql time to say: is filed1 in (...) how ever long (...) is
An example wuld be:
a.attname in ('hello','goodbye','baisc','perl')
but I do not want to have to know the case a.attname although I can
manipulate (..) to either.
