Hi,
REGEXP_LIKE ( str
         , '([[:alpha:]]).*\1.*\1'
         )returns TRUE if (and only if) the same letter of the alphabet occurs at least 3 times in str. The 3 letters don't have to be in a row. For example str='banana' would return TRUE, because 'banana' contains 3 'a's. If you want the 3 letters to be consecutive, then leave out the '.*'s.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using. REGEXP_LIKE works in Oracle 10 (and up).
