Thread: PL/PGSQL

    Hello together!

I have a little question, because I found the answer nowhere in the Net.
How I can call a stored pl/pgsql-function from my SQL-Client.
In an SQL-statement I call it like "select MYFUNCTION(blah, blah) from
...".
I need it without the SQL-Statement.

In Oracle I would be:
BEGIN
   MYFUNCTION(...);
END;

How can I do this with PG?

Greets,
   Markus

Hello Mauri!

Thank you for your comment, but it doesn´t work in this way. Meantime I
found the solution.
You can avoid this problem through calling the function direct with:

SELECT myfunction(blah, blah)

You're probably looking from the wrong place. At least the answer can be
found from
http://www.postgresql.org/docs/view.php?version=7.3&idoc=0&file=plpgsql-statements.html

On that page, heading 19.5.3 states that you can do:

    PERFORM MYFUNCTION(...);

if you wish to discard the return value.
Or if your function returns something then you do:

    myresult:=MYFUNCTION(...);
