sql set xact_abort on 用例

set xact_abort on  

设置事务回滚的
当为ON时，如果你存储中的某个地方出了问题，整个事务中的语句都会回滚
为OFF时，只回滚错误的地方

例子 ：

ALTER  proc  [dbo].[BuChongZhaiQuan_SQl]

as 
begin
	set xact_abort on
  begin transaction
		--if exists(select 1 from InvestorApply where RedeemDate=(select ShouldPayDate=max(ShouldPayDate) from ActualRedemptionIncome) and CheckState=9)
		if exists(select 1 from InvestorApply where  CheckState=9 and DeleteState=0)
		--if(1<>1)
		print '暂不补充比例'
	else 
		begin
		print '执行补充比例,第一步'

		insert  into NewBuChong 
		select ApplicationID,ststus=0, REPLACE(CONVERT (VARCHAR(100),getdate(),23),'-',''),getdate()
		--,ttt.真实匹配比例 ,TTT.LoanDate
		from  tb_sanbiao_20160215_InvestorApplyID

		end
		if(@@error<>0)
		begin
			select 'Error'
			rollback tran		
			return;
		end
		else
		begin
			commit;
			select 'OK'
		end
end
