如何解决如何使该查询起作用？
| 我昨天发布了这个问题，由于某种原因我无法使其正常工作。我得到了很多很好的答案，但它们不符合我需要的范围。基本上，我需要运行一个查询，该查询将遍历所有客户，并抓住他们的Acct_Balance并将其设置为0，但是在将其设置为0之前，我需要向AR_Transactions表中添加该金额为负的条目。因此，出于实数的考虑，如果客户在客户表的Acct_Balance字段中具有-200，那么我需要添加一个条目或200才能将值设置为0。有点类似于将订单项设置为0。反之，如果客户在客户表的Acct_Balance字段中有200，那么我也需要添加一个条目或-200来将其归零。我尝试了几件事。这是我尝试过的示例之一。BEGIN TRANSACTION
INSERT INTO [cresql].[dbo].[AR_Transactions]
(Trans_ID,DateTime,Dirty,Store_ID,Trans_Type,Cashier_ID,CustNum,Trans_Amount,Prev_Cust_Balance )
SELECT (SELECT MAX(Trans_ID ) + 1 FROM [cresql].[dbo].[AR_Transactions]),DATEADD(MINUTE,-30,Getdate()),1,1001,\'C\',100199,-Acct_Balance,Acct_Balance
FROM [cresql].[dbo].[Customer]
WHERE Acct_Balance <> 0
UPDATE [cresql].[dbo].[Customer] SET Acct_Balance = 0
WHERE Acct_Balance <> 0
COMMIT TRANSACTION
Msg 2627,Level 14,State 1,Line 3
