Question

现在我将光标更新为2个表，并根据特定的select语句插入一个表中，此select语句返回2列x，yi需要x在表“PX”中更新，因为x是此表中的主键，需要x在表“FX”中更新，因为x是此表中的外键，然后插入第三个表x数据。

我需要更改此光标并使用我尝试的更新和插入脚本，但我发现我需要循环才能实现我的目标，所以如果有人知道我是否可以更改此光标。

并提前致谢

DECLARE @id int
DECLARE @clientid uniqueidentifier
DECLARE @code int
DECLARE @Wtime int

DECLARE @closeComplaint CURSOR
SET @closeComplaint = CURSOR FAST_FORWARD 
FOR
    SELECT ComplaintId, [ClientId]
    FROM complaint
    WHERE ComplaintStatusId = 5  
      AND (waitingForCutomerCloseDateTime < GETDATE() OR
           waitingForCutomerCloseDateTime = GETDATE())   

OPEN @closeComplaint

FETCH NEXT FROM @closeComplaint INTO @id, @clientid

WHILE @@FETCH_STATUS = 0
BEGIN
    SELECT 
        waitingForCutomerCloseTime = @Wtime 
    FROM
        SystemConfiguration 
    WHERE
        ClientId = @clientid

    SELECT 
        [Code] = @code 
    FROM
        [dbo].[resp_users] 
    WHERE
        ClientId = @clientid

    UPDATE activity 
    SET ActivityStatus = 4, 
        CompletionDate = GETDATE(),
        ClosedBy = @code 
    WHERE [ComplaintId] = @id

    UPDATE [dbo].[Complaint] 
    SET ComplaintStatusId = 2 
    WHERE [ComplaintId] = @id

    INSERT INTO [dbo].[Note] ([Note_Description], [ClientId], [User_Code], [Visible_Internal],
                              [ComplaintId], [Note_DateTime], [ComplainantId],
                              [OneStopDesk_CustomerEmail], [OneStopDesk_CustomerUsername], [Private])
    VALUES (N'Automatically closed by system after ' + @Wtime, @clientid, @code, 1,
            @id, GETDATE(), null, null, null, 1)

    FETCH NEXT FROM @closeComplaint INTO @id, @clientid
END

CLOSE @closeComplaint
DEALLOCATE @closeComplaint

我不是完全确定我把一切都搞定了（你没有发布表格结构，所以我真的只能猜测有时这些表是如何连接的） - 但你应该能够基本上在 3个简单的，基于集合的语句中完成所有这些 - 并且应该比光标更快 LOT ！

-- declare table variable
DECLARE @Input TABLE (CompaintID INT, ClientID INT)

-- save the rows into a table variable
INSERT INTO @Input (ComplaintID, ClientID)
   SELECT ComplaintID, ClientID
   FROM dbo.Complaint
   WHERE ComplaintStatusId = 5
     AND waitingForCustomerCloseDateTime <= GETDATE()

UPDATE a 
SET ActivityStatus = 4, 
    CompletionDate = GETDATE(),
    ClosedBy = u.Code
FROM dbo.Activity a
INNER JOIN @Input i ON a.ComplaintId = i.ComplaintId
INNER JOIN dbo.resp_users u ON i.ClientId = u.ClientId

UPDATE dbo.Complaint
SET ComplaintStatusId = 2 
WHERE 
    ComplaintStatusId = 5
    AND waitingForCustomerCloseDateTime <= GETDATE()

INSERT INTO dbo.Note ([Note_Description], [ClientId], [User_Code], [Visible_Internal],
                      [ComplaintId], [Note_DateTime], [ComplainantId],
                      [OneStopDesk_CustomerEmail], [OneStopDesk_CustomerUsername], [Private])
    SELECT
        N'Automatically closed by system after ' + sc.waitingForCustomerCloseTime, 
        i.ClientId, u.Code, 1,
        i.ComplaintId, GETDATE(), null, null, null, 1
    FROM
        @Input i
    INNER JOIN
        dbo.SystemConfiguration sc ON i.ClientId = sc.ClientId
    INNER JOIN
        dbo.resp_user u ON u.ClientId = i.ClientId

每个更新行的SQL插入语句
