运行此查询后，出现一个自定义错误：
借记帐户余额不能少于0。somemail@7dmail.com/123/xxx/123456
以及两个常规错误：
EXECUTE之后的事务计数表明BEGIN和COMMIT语句的数量不匹配。上一个计数= 2，当前计数= 0。 ROLLBACK TRANSACTION请求没有相应的BEGIN TRANSACTION。
我认为，发生事务错误是因为在事务提交之前某些东西引发异常。 自定义错误来自下面编写的另一个查询（AddJournalEntry）。我看不到这两个查询之间的连接。

答案 0 :(得分：1)
要执行多个ROLLBACK命令，而只执行一次。回滚会将事务计数从大于0的任何金额直接降低到0，因此如果执行3 BEGIN TRANSACTION，则@@TRANCOUNT为3，回滚会将其设置为0。问题是您在被调用的SP（嵌套的SP）内部执行回滚，并在SP返回之后再次执行回滚。
您可以在此示例中看到问题：
BEGIN TRANSACTION
SELECT @@TRANCOUNT -- 1
BEGIN TRANSACTION
SELECT @@TRANCOUNT -- 2
ROLLBACK
SELECT @@TRANCOUNT -- 0
ROLLBACK -- The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION.
这是您的SP执行失败的路线：
CREATE PROCEDURE [dbo].[RevokeOrder]
@OrderId int = null
AS
begin tran -- Create a transaction here (TRANCOUNT = 1)
if (...)
begin
EXECUTE @RC = [dbo].[AddJournalEntry] -- Executes a rollback inside
if @@ERROR <> 0 or @RC <> 0
begin
rollback -- When the execution reaches this rollback, TRANCOUNT is 0 and the rollback fails
raiserror ('Revoke order process. Can not add reverse blocked quote amount journal entry', 16, 1)
return 4
end
end
END
SP被称为：
CREATE PROCEDURE [dbo].[AddJournalEntry]
AS
BEGIN
begin tran -- TRANCOUNT = 2
if (@DebitBalance < 0 and @ToIncrease = 'debit') or (@DebitBalance > 0 and @ToIncrease = 'credit')
begin
rollback -- Undoes all changes from the start of the first BEGIN TRAN and sets TRANCOUNT to 0
set @Error = 'Debit account balance can not be less than 0. ' + @DebitAccountTitle
raiserror (@Error, 16, 1)
return 5
end
END
我建议使用TRY / CATCH块并在ROLLBACK上进行CATCH。如下所示：
CREATE PROCEDURE [dbo].[RevokeOrder]
@OrderId int = null
AS
BEGIN TRY
begin tran
if (...)
begin
EXECUTE @RC = [dbo].[AddJournalEntry]
if @@ERROR <> 0 or @RC <> 0
begin
raiserror ('Revoke order process. Can not add reverse blocked quote amount journal entry', 16, 1)
return 4
end
end
COMMIT
END TRY
BEGIN CATCH
IF @@TRANCOUNT > 0 -- Might want to check XACT State also
ROLLBACK
-- Additional logging/fixing stuff
END CATCH
END
