 4 AS
 5 BEGIN
 6     SET NOCOUNT ON

10         insert into Test_Commit (b) values (3)
11  
12         insert into Test_Commit (a,b) values (1,3)
13         set @result=1
14       commit tran yy            
15                   end try   
16 begin catch
17         set @message= ERROR_MESSAGE() 
18         set @result=0
19         rollback tran yy        
20         --insert into SYS_Proc_Message([Message]) values(ERROR_MESSAGE())
