查询整个数据库中某个特定值所在的表和字段的方法

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。
