SQLSERVER查詢整個數據庫中某個特定值所在的表和字段的方法

 

作項目中前些天要手動改數據庫中的一些字段的值,但發現這個字段可能會被數據庫中其餘的不少張表引用,因而就得想辦法查詢出該條記錄的全部引用的表和字段,下面的存儲過程能夠查詢出整個數據庫中某個特定值所在的表和字段。sql

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

只須要傳入一個想要查找的值,便可查詢出這個值所在的表和字段名。數據庫

EXEC [SP_FindValueInDB] 'GetAllCar'

查詢出來的結果以下:spa
