SQL SERVER中 存储过程使用事务与捕获异常

一、格式类似于

CREATE PROCEDURE YourProcedure
AS
BEGIN
SET NOCOUNT ON;

BEGIN TRY---------------------开始捕捉异常
BEIN TRAN------------------开始事务
UPDATE A SET A.names = B.names FROM 表1 AS A INNER JOIN 表2 AS B ON A.id = B.id

UPDATE A SET A.names = B.names FROM 表1 AS A INNER JOIN 表2 AS B ON A.TEST = B.TEST

COMMIT TRAN -------提交事务
END TRY-----------结束捕捉异常
BEGIN CATCH------------有异常被捕获
IF @@TRANCOUNT > 0---------------判断有没有事务
BEGIN
ROLLBACK TRAN----------回滚事务
END
EXEC YourLogErrorProcedure-----------记录存储过程执行时的错误信息，自定义
END CATCH--------结束异常处理
END

二、实例

ALTER PROC usp_AccountTransaction

@AccountNum INT,

@Amount DECIMAL

AS

BEGIN

BEGIN TRY --Start the Try Block..

BEGIN TRANSACTION -- Start the transaction..

UPDATE MyChecking SET Amount = Amount - @Amount

WHERE AccountNum = @AccountNum

UPDATE MySavings SET Amount = Amount + @Amount

WHERE AccountNum = @AccountNum

COMMIT TRAN -- Transaction Success!

END TRY

BEGIN CATCH

IF @@TRANCOUNT > 0
BEGIN
ROLLBACK TRAN --RollBack in case of Error
END
EXEC YourLogErrorProcedure-----------记录存储过程执行时的错误信息，自定义
END CATCH
END

GO
