:)   Apart from Ronald J Reinhart, I think you guys should seriously consider looking at the Regexp classes in 1.4...  They would save you a lot of heartache.   An interesting thread to watch nonetheless.   Regards Jason Bell -- ----- Original Message ----- From: Greg Nudelman To: jdjlist Sent: Thursday, March 27, 2003 2:41 AM Subject: [jdjlist] Re: String List Compare Just finished it! Actually, aside from the dreadfull-looking SQL, it's quite fast. Only 1.85 seconds!   Thanks again, this is one happy camper!   Greg Nudelman -----Original Message----- From: Armando Valenzuela [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 26, 2003 5:40 PM To: jdjlist Subject: [jdjlist] Re: String List Compare Hi.. You can try  (if you can) by changing your DB structure making a N-N table (relational) ,  { key of table x , key of table states  }. and make a db index of  key-state in the N-N table, and the respective query..         ----- Original Message ----- From: Greg Nudelman To: jdjlist Sent: Wednesday, March 26, 2003 3:13 PM Subject: [jdjlist] Re: String List Compare Dear DR, sorry but I can't give you any details, and here is why: 1) The one reason for the predicament is that legacy DB structure is horrible, and this query will be 2 pages long, and not likely to EVER come up again (I sincerely hope others do not have the same to deal with!!)  2) Explanation will take 2-3 pages, time I do not have. 3) I'm still coding the solution!!! 4) I can't reveal the particulars of the IMX internal DB structure... do you want the Lawyers after both of us??!! :-) But seriously, the point was that using the SQL LIKE *is* the solution here.  As long as you can bypass any String operations in Java and twist and turn your (even VERY, VERY, VERY badly designed) legacy table structure around so you can somehow (self-join, union, group by N different columns together, etc.) do it in the SQL in the DB, you're way way ahead of any Java solution.  That is the take-home lesson here. But if you have some kind of tricky problem YOU are working on, post away, I'd love to have a crack at it! Cheers!
