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
