如果我理解正确的话

DELETE statements must restrict all PRIMARY KEY columns with equality relations in order to delete non static columns

它声明我的所有主键都应该有相等符号，即 = 这是我用来删除的查询

DELETE FROM service.data WHERE product_uuid=432523b3-8094-4a0d-b93a-cc8d22100f85 AND item_uuid=a709c5cc-8f98-4cba-b1dc-264b0fd24e08 IF EXISTS;

怎么查询错了？？从数据表中删除一行的正确方法是什么？？
