在插入多行時增加一個變量存儲過程

Question

我想在插入多行時增加一個變量。

這是我最後一次嘗試。

DECLARE @i int 
Set @i=0 
Insert into winners (ContestantID, DrawingID, SlotNumber) 
SELECT TOP (@Total) ID, @DrawingID, @i + 1 FROM Contestants 
where Drawingid=@DrawingID ORDER BY NEWID() 

Answer 1

使用ROW_NUMBER函數：

INSERT INTO winners (ContestantID 
    , DrawingID 
    , SlotNumber) 
SELECT TOP (@Total) ID 
    , @DrawingID 
    , ROW_NUMBER() OVER (ORDER BY ID) 
FROM Contestants 
WHERE Drawingid = @DrawingID 
ORDER BY NEWID()
