Question

I’m trying to delete a “boat” from boat table and associated qualifications in another table using the following code:

DELETE FROM tbl_boat, tbl_qualifications 
WHERE tbl_boat.BT_ID = '$bt_id' AND tbl_boat.BT_ID = tbl_qualifications.BT_ID;

The problem is I’m receiving following error:

1064 – You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE tbl_boat.BT_ID = 113 AND tbl_boat.BT_ID = tbl_‘ at line 2 .

Appreciate any help on this.

Answer 1

You need to perform two delete :

— DELETE all associations first …
DELETE FROM tbl_qualifications WHERE BT_ID = ‘$bt_id’;

— … then delete the boat
DELETE FROM tbl_boat WHERE BT_ID = ‘$bt_id’;
