- md5 takes TEXT as an argument, not a numeric type
- assign each variable of type tSession to its corresponding value:
thisSession.ty_ found := ''t'';
thisSession.ty_ session := md5(CAST((now( )) AS TEXT));
I haven't looked up the rand() function, but you can see from this how
you would cast it and now() to text.

In the above reply, I forgot to mention that you are not using the
integer you are passing in as an argument. If you need it (rand()?)
you'll have to declare it:
myInt ALIAS FOR $1;
or use it explicitly with just the name: $1

Since it works you surely fixed my code but this should't be an issue
since I tried

----------------------------------
154e80496745114 8bba5f28e044be8 28

----------------------------------
31313f537b69d5f fe61be024a40b80 7e
(1 row)
and they worked.
and yeah I messed up remembering mySQL code and wrote rand( ) inspite
of random( )
Can't user composite type be initialized in a shortest way?
eg. ( ( ), ( ), , ( ), , , ( ), ...)
I thought they could. I saw a similar syntax somewhere in the docs. Am
I daydreaming?
One more thing about the first example presented in this page: http://www.postgresql.org/docs/7.4/s...pressions.html
I just tried
create or replace function GetSessionID( integer )
returns tSession as '
declare
thisSession tSession;
begin
thisSession.ty_ Found := ''t'';
thisSession.ty_ Session := now( );
return thisSession;
end;
' language plpgsql;
and it returns execution time not "plan" time. Does "plan" time is
strictly referred to SQL statements?
thanks for your help

TEXT argument....... .. and yeah I messed up remembering mySQL code and wrote rand( ) inspite of random( )

I'm not sure I understand what you're asking here. CURRENT_TIMESTA MP and
now() return the start time of the current transaction, would that be
the "plan" time? The timeofday() function returns the "wall clock" time
and advances during transactions. I think that this would be the
"execution" time.
Hope that helps

Well I've read about composite type but all the references I've seen

I was expecting to declare composite types in plpsql or plain sql in a
similar way I'd do in C/C++ with struct/class.

FYI, mostly. But I do have questions as to how to write code
that will continue to work in subsequent postgresql versions.
See code below.
begintest() uses EXIT to exit a BEGIN block from within nested

begintest2() simplifies this, omitting the nested loops.
Still no problem.

Basically I'd like to implement the composite design pattern with leaves that
are either of reference or value types, but even using generics I can't seem
to avoid boxing (using ArrayList or Object)
Is this even possible, or is the composite pattern doomed to use the
System.Object type forever?
I have tried using interfaces with generics, but I always stumble on the
Value property (when trying to return the value of a particular node)
