如何删除同表MySQL中的select

Question

您好，我有一个在SQLite中使用了很长时间的相当复杂的查询。它是这样开始的：

delete FROM 
   verbal_sets 
WHERE verbal_sets.verbal_set_id IN( 
   SELECT 
       F.verbal_set_id 
   FROM verbal_sets AS F WHERE Exists( 
       SELECT 
         knowledge_id, phrase_id,first_entity_text, second_entity_text,verbal_relation_text, Count(verbal_set_id) 
       FROM
        (...)

我现在正在创建同一软件的MySQL支持版本，但是MySQl不喜欢这个查询。它返回错误：

[Err] 1093 - You can't specify target table 'verbal_sets' for update in FROM clause

我没有MySQL细节方面的经验。谁能告诉我这个查询必须做些什么？

Answer 1

我希望这能帮到你

delete FROM 
   verbal_sets 
WHERE verbal_set_id IN( 
   SELECT * 
    From( 
       SELECT knowledge_id, 
              phrase_id,
              first_entity_text, 
              second_entity_text, 
              verbal_relation_text, 
              Count(verbal_set_id) 
       FROM  verbal_sets
       ) as c
)

Answer 2

只需跳过几行：

DELETE FROM 
   verbal_sets 
WHERE Exists( 
       SELECT 
         knowledge_id, phrase_id,first_entity_text, second_entity_text,verbal_relation_text, Count(verbal_set_id) 
       FROM
