Question

有时我们需要使用我们的客户端数据进行调试，而我们没有时间进行完整的数据库备份，因此我们手动将sql结果转换为静态'select UNION select UNION'的组合，以便我们可以即时使用他们的数据...

示例：

select * from items

结果：

Itemcode     ItemName     Price
Car1         FerrariX     1200.00
Car2         FerrariZ     3000.00
Car3         MustangR     2100.00

我们将它带回到我们这样的环境中：

select 'Car1' as Itemcode, 'FerrariX' as Itemname, 1200.00 as 'Price' UNION
select 'Car2',             'FerrariZ', 3000.00 UNION
select 'Car3',             'MustangR', 2100.00

Posible Stored Procedure Solution：

EXEC spQueryAsStaticData @Query = 'select * from items'

我们如何自动进行此转换？一些存储过程？

Answer 1

我使用这样的东西用数据打印文本

DECLARE @i int
DECLARE @employee_id int
Declare @Hash nvarchar(max)
declare @Result nvarchar(max)
Declare @String nvarchar(MAX)
DECLARE @numrows int
DECLARE @employee_table TABLE (
    idx smallint Primary Key IDENTITY(1,1)
    , [ID] int , [Hash] nvarchar(50), Result nvarchar(50)
)


INSERT @employee_table
SELECT Top 5 * FROM [Hlist].[dbo].[MD5]
set @i =0 
set @String = '' 


SET @numrows = (SELECT COUNT(*) FROM @employee_table)

IF @numrows > 0

    WHILE (@i <= (SELECT MAX(idx) FROM @employee_table))
    BEGIN


        -- get the next employee primary key
        SET @employee_id = (SELECT ID  FROM @employee_table WHERE idx = @i)
        SET @Hash = (SELECT Hash  FROM @employee_table WHERE idx = @i)
        SET @Result = (SELECT Result  FROM @employee_table WHERE idx = @i)
        Set @String = coalesce(@String +'Select '+ convert(varchar,@employee_id) + ', ' +@Hash+ ', '+@Result +' Union ', '')

        --
        -- do something with this employee
        --


        -- increment counter for next employee
        SET @i = @i + 1
    END


    Print @String

最后我们解决了它开发一个小C＃应用程序，没有像直接从SQL查询生成它那样有用但是它有效......

如果有人提供SQL解决方案，我们会给他/她
