查找具有兩個指定列名的SQL Server表

Question

我想在sql server中搜索具有兩個特定列名ex（columnA和columnB）的表。我有一個查詢，在一列名搜索

SELECT name FROM sysobjects WHERE id IN 
(SELECT id FROM syscolumns WHERE name = 'columnA') 

我不知道如何修改此以搜索兩列。

Answer 1

SELECT name FROM sysobjects WHERE id IN 
(SELECT id FROM syscolumns WHERE name = 'columnA') 
and id in 
(SELECT id FROM syscolumns WHERE name = 'columnB') 

應該這樣做。

Answer 2

嘗試類似：

select syscolumns.id, sysobjects.name from syscolumns 
    join sysobjects so on sysobjects.id = syscolumns.id 
where exists (select 1 from syscolumns sc where sc.id = syscolumns.id and name = 'columnA') 
    and exists (select 1 from syscolumns sc2 where sc2.id = syscolumns.id and name = 'columnB') 

Answer 3

這是做正確的方式：

select so.name 
from sysobjects so 
where so.type = 'U' -- it's a user's table 
and exists (select * from syscolumns sc where sc.id = so.id and sc.name='columnA') 
and exists (select * from syscolumns sc where sc.id = so.id and sc.name='columnB') 

它來檢查，這是一個用戶表是很重要的。相反，你可以找到視圖，表值函數等等。
