当数据库做的太庞大的时候，难免会出现忘记哪个值会存入哪个表的情况，于是在网上找到的如下解决办法。
通过做一个存储过程，只需要传入一个想要查找的值，即可查询出这个值所在的表和字段名。前提是要将这个存储过程放在所查询的数据库。
CREATE PROCEDURE [dbo].[SP_FindValueInDB]
(
@value VARCHAR(1024)
)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
DECLARE @sql VARCHAR(1024)
DECLARE @table VARCHAR(64)
DECLARE @column VARCHAR(64)
CREATE TABLE #t (
tablename VARCHAR(64),
columnname VARCHAR(64)
)
DECLARE TABLES CURSOR
FOR
SELECT o.name, c.name
FROM syscolumns c
INNER JOIN sysobjects o ON c.id = o.id
WHERE o.type = 'U' AND c.xtype IN (167, 175, 231, 239)
ORDER BY o.name, c.name
OPEN TABLES
FETCH NEXT FROM TABLES
INTO @table, @column
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sql = 'IF EXISTS(SELECT NULL FROM [' + @table + '] '
SET @sql = @sql + 'WHERE RTRIM(LTRIM([' + @column + '])) LIKE ''%' + @value + '%'') '
SET @sql = @sql + 'INSERT INTO #t VALUES (''' + @table + ''', '''
SET @sql = @sql + @column + ''')'
EXEC(@sql)
FETCH NEXT FROM TABLES
INTO @table, @column
END
CLOSE TABLES
DEALLOCATE TABLES
SELECT *
FROM #t
DROP TABLE #t
End
例如，要查询‘admin’，新建一个查询输入
EXEC SP_FindValueInDB 'admin'
会返回相应记录，Tablename显示被查询数据所在表，Columnname显示被查询数据所在列。
