将数据从 table 插入相同的 table 作为具有新自动递增 id 的新行，使用游标逐行进行

Question

这是一个基于我的数据的示例table

我的问题：

伪代码（为清楚起见）：

对于 tbl 中的每个位置 ouote_id
- 根据任何报价 ID 将每一行的数据插入到新行中。

基本上我想复制所有内容并将其重新插入到相同的 table 但每一行都有一个新的自动递增 ID，因此就像一个新的引用 ID。但是该行仍然具有相同的报价 ID。

为此，我的同事说我应该使用游标。我相信我的游标逻辑有些不正确，但我不确定为什么。我已经尝试过 Rubberducking 方法，但我编写的代码在逻辑上似乎是正确的。

这是我的代码：

 BEGIN TRAN

 DECLARE @OldId INT
 DECLARE @QuoteID INT
 DECLARE @NewQuoteID INT

 SET @QuoteID = 71475

 DECLARE @NewLocationID INT
 SET @NewLocationID = 0

DECLARE Location_Cursor CURSOR FOR 
     SELECT id 
     FROM tbl_Quote_Scheduled_Locations 
     WHERE Ouote_ID = @QuoteID

OPEN Location_Cursor

FETCH NEXT FROM Location_Cursor INTO @OldId

WHILE (@@FETCH_STATUS = 0)
BEGIN
    INSERT INTO tbl_Quote_Scheduled_Locations ([Account_ID], [Agent_ID],[LocationName], [Address], [City], [State], [Zip], [Ouote_id])
        SELECT 
            [Account_ID], [Agent_ID], [LocationName], [Address], [City],[State], [Zip], @QuoteID
        FROM 
            tbl_Quote_Scheduled_Locations
        WHERE 
            @QuoteID = @NewQuoteID      

    FETCH NEXT FROM Location_Cursor INTO @OldId         
END

CLOSE Location_Cursor   
DEALLOCATE Location_Cursor

--Check to see if update worked (I keep getting no value back)
SELECT s.id, s.Ouote_ID
FROM tbl_Quote_Scheduled_Locations s
WHERE @NewLocationID = SCOPE_IDENTITY()

ROLLBACK

有人可以帮助我理解为什么我的上述代码不起作用吗？

我不确定这是否与我的 INSERT 语句本身有关，或者我是否错误地创建了游标。

感谢您的帮助

Answer 1

这里绝对不需要那些可怕的、低效的游标之一……

只需使用简单、简单、简单的基于集合的方法：

SET @QuoteID = 71475

INSERT INTO tbl_Quote_Scheduled_Locations ([Account_ID], [Agent_ID],[LocationName], [Address], [City], [State], [Zip])
    SELECT 
        [Account_ID], [Agent_ID], [LocationName], [Address], [City],[State], [Zip]
    FROM 
        tbl_Quote_Scheduled_Locations
    WHERE 
        @QuoteID = @QuoteID;

DECLARE @NewQuoteId = SCOPE_IDENTITY();

我假设 QuoteId 是自动递增列？只是 在执行 INSERT 时不要指定 - 然后 SQL 服务器将分配一个新值。

我为其他也在为此苦苦挣扎的人提出了解决方案... Answer 从每一行插入数据并保持更新的新报价 ID。

DECLARE @QuoteId int 
SET @QuoteId = 68548
DECLARE @NewId int
DECLARE @OldId int
