I've spent the last few hours trying to come up with a function that
at the most basic returns the result of a SELECT * FROM <table>.
This is easy to do in something like MSSQL or Oracle. For example in
MSSQL i can do something like:
CREATE PROCEDURE proc_name AS
BEGIN SELECT * FROM sometable
END
How do I do something like that with a Postgresql function/stored
procedure? All I really want to know is how to by using a function how
can I return the results of a SELECT * query!?
The end result of the query I need is more complicated, but I can't
even get something that easy to work. Are functions unable to return
result sets?? All of the examples i've seen always return a single
value, like an int. That doesn't do me any good.
I want to use a few stored procedures to create some faster processing
for some queries that involve 3-4 tables plus require some input
parameters, and return a result set.
Any help would be appriciated. I've just recently started using
PostgreSQL and I'm very impressed! I'm sure I'm jsut overlooking
something easy, but for the life of me i just cant figure it out.
Thanks,
John
