Ошибка запроса

[M1ronz0r]

Сам запрос:

format(query, sizeof query, "UPDATE houses SET owner = 'Null', lock = '1' WHERE id = '%d' LIMIT 1", GetPlayerVirtualWorld(playerid));
		            mysql_function_query (DBConnect, query, false, "", "") ;

В логе ошибка:

[18:09:23] EID: 1064 | Error: 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 'lock = '1' WHERE id = '1000' LIMIT 1' at line 1 | Query: UPDATE houses SET owner = 'Null', lock = '1' WHERE id = '1000' LIMIT 1

Не могу понять в чем дело..
