Re: String manipulations HELP!!!!

Answer to your first question:

select column_name
from user_tab_columns
where instr(column_name, '_ID') > 0
and substr(column_name, 1, instr(column_name, '_ID')-1)

       ||'_ID' = column_name
/

I am pretty sure this query can be optimized, but I suggest you think along these lines.
