Ah... e... let me do some testing. In the past, simply running alter table would drop the foreign keys. Now that things are different, I will have to see what works (or ask Heikki about it) Cheers! -- Zak Greant <[EMAIL PROTECTED]> | MySQL Advocate | http://zak.fooassociates.com MySQL Tip: Show the configuration options set in the server % mysqld --print-defaults Sincere Choice: Supporting a Fair Software Market (http://sincerechoice.org) - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

RE : Dropping foreing key without losing data
Hello Zak, Thanks for your response. I try the way you told me, but it seems there is another problem : The old foreign keys always exist. In consequence, there are double references. How can i resolve that problem ? Thanks in advance.

Hello JeanClaude, Unfortunately, foreign keys cannot currently be conveniently dropped. :( The InnoDB developer plans to implement this in the near future. The only option currently is to recreate the table structure, move the data into the new table, drop the old table and then rename the table.
