删除语句有效但不删除行

Question

我想做一个删除语句，我想删除另一个选择的 table 中的一些文章。我创建了该语句，但是当我运行它时，它不会删除任何内容。这是运行ning，但没有删除任何行。

delete from article  where (client_id, art_no) in ( select art_no, client_id from art_del as A 
inner join (select distinct client_id from article) as D on a.cliend_id = d.client_id 
where label not in (0,-1));

where子句中的数据看起来不错，但是当我执行删除时它不会删除任何东西。

Answer 1

where 子句是这样的：

where (client_id, art_no)

所以这对有第一个 client_id 然后 art_no 但在子查询中，顺序不同：

select art_no, client_id

更改为：

delete from article  
where (client_id, art_no) in ( 
  select client_id, art_no
  from art_del as A inner join (
    select distinct client_id 
    from article
  ) as D on a.cliend_id = d.client_id 
  where label not in (0,-1)
);
