Sql Server 中事务（begin tran/commit tran/rollback tran）的用法

ALTER PROCEDURE [dbo].[Proc_Test_commit1]
@result int output,	--成功 1; 失败 0
@message nvarchar(20) output
AS
BEGIN
SET NOCOUNT ON

begin try
begin tran yy
insert into Test_Commit (b) values (3)

insert into Test_Commit (a,b) values (1,3)
set @result=1
commit tran yy
end try
begin catch
set @message= ERROR_MESSAGE()
set @result=0
rollback tran yy
--insert into SYS_Proc_Message([Message]) values(ERROR_MESSAGE())
print ERROR_MESSAGE()
end catch

SET NOCOUNT OFF;

END
