Question

我需要一个类似于mysql的查询：

SELECT * FROM table_name 
WHERE column_name like %value% 
   IN (SELECT * FROM table_name WHERE column_name like %second_value%)

我该怎么做？

谢谢！

Answer 1

由于我对您的问题的理解是正确的，因此您的查询必须是：

SELECT * FROM table_name 
WHERE column_name like '%value%' and column_name like '%second_value%'

Answer 2

您无法从嵌套的IN查询中选择多个列。您只能选择一列。

我假设您要从嵌套查询中选择column_name。

SELECT * FROM table_name WHERE column_name like '%value%' IN
(SELECT column_name FROM table_name WHERE column_name like '%value%')
//      ^^^^^^^^^^^

SELECT * FROM table_name WHERE column_name like％value％IN（SELECT ...？
