Auto Increment after delete in MySQL

Question

I have a MySQL table with a primary key field that has AUTO_INCREMENT on. After reading other posts on here I\'ve noticed people with the same problem and with varied answer

Answer 1

There is actually a way to fix that. First you delete the auto_incremented primary key column, and then you add it again, like this:

ALTER TABLE table_name DROP column_name;
ALTER TABLE table_name ADD column_name int not null auto_increment primary key first;
