Hello, I am having a problem with this correlated sub query. I get a syntax error at the second SELECT. This is part of a larger query with other aggregated sub queries or I would consider a JOIN instead. I tried running the sub query by itself and it works. I tried LEAST for MIN, same result. The jobnumber/jobno fields are Chars and the schstartrun is a Double. I am developing on Windows XP with MySQL 4.17.
Thanks for any help Glenn SELECT pj.jobnumber, (SELECT MIN(pl.schstartrun) FROM plist pl WHERE pl.jobno = pj.jobnumber AND pl.schstartrun > 0) AS SchStart FROM planjobs AS pj Glenn Holden - Pivotal Z [EMAIL PROTECTED] / 303 400 0573 / www.pivotalz.com 17328 E Bates Place, Aurora, Colorado 80013-2206 / fax 425 984 0297 -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
