Hello,

I'm new in PostgreSQL. It's very cool.

I would like to know how to return a set of records from a stored procedure.

For example, i would like to execute these sql command from a stored
procedure :

select t.typnum, t.typcom, t.typcateg, s.symurlgraph from structure.type t
left join structure.symbole s
on t.typcode = s.typcode;

Is it possible ?
Do i have to return results in an array ?
If yes, how could i do ?

Do you think using plPHP mays help me ?

Regards,
Patrice OLIVER.
