Hi,
i have written a SP. But now I want to set debug mode on and wants to diaplay those debug messages. e.g. let say before executing a statement in side the SP, i want to siplay some message like "executing insert stmt for table1" and then SQL statement needs to executed.

plz help me on this.

Thanks
Surjya

I create a log table with just a single large VARCHAR column and insert debug records as I need them. I then examine the log table after I run the program.

delete from temp_log_file;
insert into temp_log_file values (varchar(current_timestamp)||' start of debug');
...
...
insert into temp_log_file values (varchar(current_timestamp)||' '||varchar(some_variable)||' before calc' );
commit;
...
insert into temp_log_file values (varchar(current_timestamp)||' '||varchar(some_variable)||' after calc' );
commit;

I always commit after each insert in case the program crashes and does a rollback so I can see where it was.

If you have an external routine, you can write to a file. On z/OS, you can write to standard output/standard error and see this output in the WLM output
