Theoretically, you should be able to do a multi-table update since MYSQL 3.23, like this:
UPDATE tablename, tablename2 SET tablename.field1 = 'yes' WHERE tablename.userid = tablename2.userid; I haven't tested it, though. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: 1. júlí 2003 02:33 To: [EMAIL PROTECTED] Subject: [PHP] need help w/ sql query - update and select at once hi i'm trying to get this sql query to work, i'm trying to update and select at the same time, i'm not even sure if this is even possible update db.tablename set field1='yes' where (select * from db.tablename,db.tablename2 where db.tablename.userid=db.tablename2.userid); basically i have a column called 'userid'. this column exists in both tablename, and tablename2. where the value of userid in tablename is equal to the value of userid in tablename2, i'd like to set the value of field1 to 'yes'. can this be done from the command line? or am i better off writing another php page to accomplish this? thanks again redmond -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
