INSERT INTO SELECT子查询返回多于1行

Question

I have query:

INSERT INTO zamowienia (id, wyslane, zdata, uwagi) 
SELECT   `id`, '0', '2016-01-22', 'TEST'  FROM TABLE
LEFT JOIN table2 ON table2.kid = TABLE.tid
WHERE name LIKE 'HOR' AND znumber LIKE '897'

If I try execute them, server return error: Subquery returns more than 1 row

But, query:

SELECT   `id`, '0', '2016-01-22', 'TEST'  FROM TABLE
LEFT JOIN table2 ON table2.kid = TABLE.tid
WHERE name LIKE 'HOR' AND znumber LIKE '897'

returns only one row.

Why server return error "Subquery returns more than 1 row"?

Answer 1

Check whether there are any INSERT triggers on table zamowienia . The trigger may be causing this error.
