I've looked through the internet with not so great results.
Here's my table:
+------------------+---------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+------------------+---------+------+-----+---------+----------------+
| jobid | int(11) | NO | PRI | NULL | auto_increment |
| locid | int(11) | YES | | 0 | |
| userid | int(11) | YES | | 0 | |
| createdate | int(11) | YES | | 0 | |
| jobapplicationid | int(11) | YES | | NULL | |
+------------------+---------+------+-----+---------+----------------+
5 rows in set (0.00 sec)
I want to change the autoincrementing primary key to jobapplicationid from its original jobid
I've tried alter table jobs_applications drop primary key jobid
with no success.
Any help would be greatly appreciated.
-- remove pk
ALTER TABLE `jobs_applications` DROP PRIMARY KEY;
-- remove auto inc
ALTER TABLE `jobs_applications` CHANGE `jobid` `jobid` INT(11) UNSIGNED NOT NULL;
-- set pk and auto inc to the other column
ALTER TABLE `jobs_applications` CHANGE `jobapplicationid` `jobapplicationid` INT(11)AUTO_INCREMENT PRIMARY KEY;
