Bonjour, When I insert a lot of rows in a table from another table in MyISAM format it seems that indexes in the destination table are not updated.
For example in table A I have index 1. This table contains many rows. I have table B with same structure as table A but empty. INSERT INTO TABLE B SELECT * FROM TABLE A; There if I do a select using index 1 on table B it's very long and "explain" on the query shows me that even if it knows about index 1 it's not using it. The solution is to do a "optimize" on table B but I wonder why indexes are not up to date after the "insert into ... select" query ? Thanks for you enlightenment :) Kinds regards, Alex. --------------------------------------------------------------------- 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?
