为什么这个SQL：delete from t_bdp_ind_commodity_and_set_sku ss,t_bdp_ind_commodity c where ss.commodity_id = c.commodity_id and c.commodity_id = 3538 and c.commodity_set_id = 8188; 会报这个错误：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 ',t_bdp_ind_commodity c where ss.commodity_id = c.commodity_id and c.commodity_id' at line 1

这个SQL语句的语法是错误的。在MySQL中，删除语句的语法应该是`DELETE FROM table_name WHERE ...`，而不是`DELETE FROM table_name1,table_name2 WHERE ...`。如果你想要同时删除多个表中的数据，可以使用MySQL的`JOIN`语句，例如：

DELETE ss,c FROM t_bdp_ind_commodity_and_set_sku ss
JOIN t_bdp_ind_commodity c ON ss.commodity_id = c.commodity_id
WHERE c.commodity_id = 3538 AND c.commodity_set_id = 8188;

这个语句将会删除`t_bdp_ind_commodity_and_set_sku`和`t_bdp_ind_commodity`这两个表中满足条件的记录。
