我需要一个字段，其值是项目的ID，我该如何实现？

I'm making an insert statement, the id field has auto_increment, another field must get the exact same value of the id field.

All I can think of is to create an hash, save it in the insert, then search for it with a select, retrieve the id and then insert it in the proper field.

I am also aware of the LAST_INSERT_ID() command, but I had problem in the past with it.

Are there other ways to achieve this?

Thank you very much

mysql_insert_id() is the best way to go, unless you're manually making your own ID's.

mysql_query("INSERT INTO mytable (product) values ('kossu')");
printf("Last inserted record has id %d
", mysql_insert_id());
