我遇到的情况是需要查找具有完全相同列的表。它的数据无关紧要 这是场景。
表1 ANIMAL
:
SrNo | NAME
1 | Giraffe
2 | Lion
3 | Zebra
表2:ANIMAL_TEMP
SrNo | NAME
1 | DOG
2 | CAT
当我有桌子动画(SrNo,NAME)时如何找到ANIMAL_TEMP(SrNo,NAME)?
答案 0 :(得分:0)
你可以试试这个吗?
SELECT o.name table_name,
STUFF(
(
SELECT ', ' + c.name
FROM sys.columns c
WHERE c.object_id = o.object_id
ORDER BY c.name
FOR XML PATH('')
),
1,
2,
''
) as columns
INTO #tmp
FROM sys.objects o
where o.type = 'U'
select t1.table_name, t2.table_name
FROM #tmp t1
INNER JOIN #tmp t2 ON t1.columns = t2.columns AND t1.table_name <> t2.table_name
