做项目中前些天要手动改数据库中的一些字段的值,但发现这个字段可能会被数据库中其他的很多张表引用,于是就得想办法查询出该条记录的所有引用的表和字段,下面的存储过程可以查询出整个数据库中某个特定值所在的表和字段。
CREATE PROCEDURE [dbo].[SP_FindValueInDB] ( @value VARCHAR(1024) ) AS BEGIN 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
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。
exec [SP_FindValueInDB] '4f02e90d-9a75-4bd9-a98f-3b6e0851c29a'
查询出来的结果如下:
