Hello,
How can i make a column auto_increment?
my table (table1):
id|others
0|x
1|x
2|x
etc
ALTER TABLE table1 ADD PRIMARY KEY (id); #oke
ALTER TABLE table1 ADD UNIQUE id (id); #oke
ALTER TABLE table1 CHANGE id id BIGINT UNSIGNED not null AUTO_INCREMENT;
OOPS: Duplicate entry '1' for key 1
Best regards,
Bas
