Question

I’m going blind here… can’t seem to find the error in this SQL:

INSERT INTO sankt_groups_order (
    parent_group_id, 
    child_group_id, 
    order
) VALUES (?,?,?)
ON DUPLICATE KEY UPDATE 
    order = ?
;

I am getting this error:

SQLSTATE[42000]: Syntax error or access violation: 
    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 'order ) VALUES ('65',NULL,'3') ON DUPLICATE KEY UPDATE order = '3'' 

Next will this SQL do what I think? I need it to insert the whole row if missing and update order if it exists… I have an index making parent_group_id and child_group_id unique.

Answer 1

order is a reserved word in mysql, you’ll have to escape it:

    child_group_id, 
    `order`
    ^--   ^--- backticks to escape
) VALUES (?,?,?)

and yes, it should do what you think. If there’s a unique/primary key violation, you’ll only change the order field.
