查询字段的值属于数据库中的哪个表的哪个列
输入数据库中包含的某一个字段的值查询到它所归属的表和字段,返回两列数据,第一列是此值归属的表名;第二列是此值对应的第一列中的表的列名。sql实现如下:
USE [数据库名] GO /****** Object: StoredProcedure [dbo].[SP_FindValueInDB] Script Date: 2017/3/5 10:35:01 --此存储过程用于查询一个值属于数据库中的那张表的哪个列,返回结果为两列,一列是表名,一列是列名 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER 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
