SQL server 在一個數據庫中搜索一個字符串返回存在這個字符串的表名語句

DECLARE @what varchar(800)
SET @what='900002' --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 ''所在的表及字段：['+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
-- 刪除遊標引用
DEALLOCATE TableCursor
