查看数据库中的字段所在的表中或某值所在的表和字段
***********************************字段在哪个表中
select tab.name table_name, col.name column_name
from sysobjects tab
left join syscolumns col on tab.id = col.id and tab.xtype = 'U'
where col.name like '%fkfz10000003%' order by 1,2
*************************************查询整个数据库中某个特定值所在的表和字段的方法
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
