我有一个包含3个不同UPDATE
个查询的存储过程。
我希望每个查询都返回一个值。
如果失败了,我不希望程序到COMMIT
,我希望ROLLBACK
告诉我三个存储过程中哪一个失败了。
我可以在非动态中执行此操作但由于某些原因,相同的规则似乎不适用于动态查询。
这是我的代码和我的尝试:
ALTER PROCEDURE [dbo].[ASP_XXNominalBalanceUPDATE]
@ORGCODE VARCHAR(6),
@NewNominal INT,
@OldNominal INT,
@BalMonth CHAR(6),
@Amt Decimal(12,2),
@FINPERIODNR INT,
@InvDetailID INT,
@Err INT = 0,
@Rows INT = 0
AS
BEGIN TRAN
SET NOCOUNT ON;
DECLARE @SQL NVARCHAR(MAX)
SET @SQL = N'SET @Err = 0

SELECT @Err = @@Error, @Rows = @@ROWCOUNT;';
-- Check if succeeded to find.
If @Err = 0 AND @Rows > 0
COMMIT TRAN
ELSE
ROLLBACK TRAN

这当然是完全未经测试的,但这应该会让你在正确的方向上轻推。

这是我最后的答案,以防万一其他人想知道我是如何解决的。
