create a unique key on city,cc columns with ignore option of alter table it will keep the first row and deletes redundant rows.
check the below link for alter table syntax http://dev.mysql.com/doc/mysql/en/ALTER_TABLE.html Anil -----Original Message----- From: Walter Pucko [mailto:[EMAIL PROTECTED] Sent: Monday, December 13, 2004 10:04 PM To: [EMAIL PROTECTED] Subject: Deleting redundant rows Hello there, I do have a table in mysql 4.x with redundant info. Only the autoincrement ID is different. Example: ID city cc 2559756 Witkop SF 2559757 Witkop SF This turns to be a huge problem since I cant find a way to delete the redundant rows with a mysql query. Is there a solution for that? I tried it with distinct, but that does not work, with subselects but this seems not to be supported. I am lost here, maybe someone with better sql knowledge can help out.
