我有一张桌子ATMStatusHistory。我想要一个IF条件，即如果Resolved特定票证的所有列值都是 1，则更新Ticket表以Closed = 1包含与该票证相关的所有代码。

Code    RawFeed   Resolved  Ticket
2341283 2350426   0         205656
2341460 2350603   1         205656
2341597 2350740   1         205656
2341689 2350832   1         205656
2341825 2350968   0         205656

我写了一个IF条件，但它不起作用：

    If Not Exists (Select * From ATMStatusHistory Where Ticket = @OriginalTicket
         AND Resolved=0 And RawFeed = 0)
        {
Insert InTo TicketFollowUp(Ticket, FollowUpText, FollowUpBy, FollowUpOn) 
  Select Code, Comments, UpdatedBy, UpdatedOn 
  From Ticket Where Code = @OriginalTicket                  

          Update Ticket Set Closed=1, ClosedOn=GetDate(), UpdatedBy=0, 
           UpdatedOn=GetDate(), Comments=' Ticket Closed by System as all Faults cleared. ' 
           Where Code = @OriginalTicket         
        }

添加插入语句的新要求：

IF NOT EXISTS 
(
  SELECT 1 FROM dbo.ATMStatusHistory 
    WHERE Ticket = @OriginalTicket
    AND Resolved = 0 AND RawFeed = 0
)
AND EXISTS
(
  -- want to be sure we only "close" a ticket once
  SELECT 1 FROM dbo.Ticket
    WHERE Ticket = @OriginalTicket
    AND Closed = 0
)
BEGIN
  INSERT dbo.TicketFollowUp(Ticket, FollowUpText, FollowUpBy, FollowUpOn) 
    SELECT Code, Comments, UpdatedBy, UpdatedOn
    FROM dbo.Ticket WHERE Code = @OriginalTicket;

  UPDATE dbo.Ticket
   SET Closed   = 1, 
      ClosedOn  = GETDATE(), 
      UpdatedBy = 0, 
      UpdatedOn = GETDATE(),
      Comments  = ' Ticket Closed by System as all Faults cleared. ' 
  WHERE Code = @OriginalTicket;
END

你可以试试这个演示：

CREATE TABLE #ATMStatusHistory  (Code  INT,  RawFeed  
    INT, Resolved INT, Ticket INT)
INSERT #ATMStatusHistory VALUES
(2341283 ,2350426   ,0         ,205656),
(2341460 ,2350603   ,1         ,205656),
(2341597 ,2350740   ,1         ,205656),
(2341689 ,2350832   ,1         ,205656),
(2341825 ,2350968   ,0         ,205656)

CREATE TABLE #Ticket (Code INT, Closed INT, ClosedOn 
    DATETIME, UpdatedBy INT, UpdatedOn DATETIME, 
    Comments VARCHAR(1000))
INSERT #Ticket VALUES
(2341283 ,1, '20120101', 1, '20120101', 'test'),
(2341460 ,1, '20120101', 1, '20120101', 'test'),
(2341597 ,1, '20120101', 1, '20120101', 'test'),
(2341689 ,1, '20120101', 1, '20120101', 'test'),
(2341825 ,1, '20120101', 1, '20120101', 'test')

DECLARE @OriginalTicket INT = 205656



UPDATE  #Ticket
SET     Closed = 1,
        ClosedOn = GETDATE(), 
        UpdatedBy = 0,
        UpdatedOn = GETDATE(),
        Comments = 'Ticket Closed by System as all Faults cleared.'
FROM    #Ticket a
JOIN    #ATMStatusHistory b ON
        b.Code = a.Code
        AND 1 = ALL(
            SELECT  x.Resolved 
            FROM    #ATMStatusHistory x 
            WHERE   x.Ticket = @OriginalTicket
            AND     x.RawFeed <> 0      
        )

SELECT  *
FROM    #Ticket

DROP TABLE #ATMStatusHistory
DROP TABLE #Ticket
