SQL Server 中根據字段值查詢其所在的表、字段

DECLARE @what varchar(800)
SET @what='123456' --要搜索的字符串
 
 
DECLARE @sql varchar(8000)
 
 
DECLARE TableCursor CURSOR LOCAL FOR
SELECT sql='IF EXISTS ( SELECT 1 FROM ['+o.name+']
WHERE ['+c.name+'] LIKE ''%'+@what+'%'' ) PRINT ''[字段值所在的表.字段]：['+o.name+'].['+c.name+']'''
FROM syscolumns c JOIN sysobjects o ON c.id=o.id
 
 
-- 175=char 56=int 可以查 select * from sys.types
WHERE o.xtype='U' AND c.status>=0 AND c.xusertype IN (175, 239, 231, 167 )
OPEN TableCursor
FETCH NEXT FROM TableCursor INTO @sql
WHILE @@FETCH_STATUS=0
BEGIN
    EXEC( @sql )
    FETCH NEXT FROM TableCursor INTO @sql
END
CLOSE TableCursor
-- 刪除游標引用
DEALLOCATE TableCursor
