In SysObjects, both functions and stored procedures are listed with type='P'. I've also checked SysProcedure table but couldn't find a column to differentiate between these two types.

Is there anyway to separately list functions and sp's without parsing their definitions?

I am sure there are several different answers to your question, so here is my suggestion. I believe the following query will list all functions within the database:

select p.proc_name from sysprocedure p,sysprocparm pp where p.proc_id = pp.proc_id and pp.parm_type=4

As I said, there are probably several different answers to your question and I am sure others will provide their own solution.

Interesting approach...

So the following would list all procedures:

select p.proc_name from sysprocedure p
except
select p.proc_name from sysprocedure p,sysprocparm pp
   where p.proc_id = pp.proc_id and pp.parm_type = 4

The following might be more efficient:

select distinct p.proc_name from sysprocedure p,sysprocparm pp where p.proc_id = pp.proc_id and pp.parm_type <> 4

Yes, both queries work, thanks. I guess sysprocparm.parm_type=4 means the "procedure" has a return parameter.

...but wouldn't it omit procedures that neither have any parameters nor a result clause, something like

create proc MyProc() begin ... end;

Yes, you are absolutely correct Volker. Bad oversight on my part.

AFAIK, there's no official column in the system catalog to distinguish procedures and functions, and historically, they could be used somewhat interchangeable.

This question leads to a workaround.

EDIT:

Well, obviously Karim's suggestion is the better one - almost an "official solution":)
