Sql Server 中根据表中的值查找表名【转】

首先，创建一个存储过程，具体代码如下

create PROCEDURE [dbo].[P_SYSTEM_FindData]
(
    @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

 

使用方法

查询代码如下（或者右键执行存储过程也行）：

DECLARE    @return_value int
 
EXEC    @return_value = [dbo].[P_SYSTEM_FindData]
        @value = N'张三'
 
SELECT    'Return Value' = @return_value
 
GO
