[PHP] Anyway to reset MySql's AUTO_INCREMENT counter?
Hi. Usually, Any AUTO_INCREMENT field in MySql table will have always an incrementing value. Now Suppose I emptied the table and then inserted one record, why not this record LAST_INSERT_ID is not '1' or '0' and why it is the lastid+1 before I empty the table? Can't I reset that pointer w/ deleting the table and creating it again? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Can't I reset that pointer w/ deleting the table and creating it again? This is the php list, not the mysql list :-) Again from the mysql manual (you should get a copy) If you delete the row containing the maximum value for an AUTO_INCREMENT column, the value will be reused with an ISAM, GEMINI or BDB table but not with a MyISAM or InnoDB table. If you delete all rows in the table with DELETE FROM table_name (without a WHERE) in AUTOCOMMIT mode, the sequence starts over for all table types. -- David Robley Techno-JoaT, Web Maintainer, Mail List Admin, etc CENTRE FOR INJURY STUDIES Flinders University, SOUTH AUSTRALIA You look like something the cat refused to drag in. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
