Re: pl/pgsql array return

Thanks Barry,

I have tried this with no luck.  I am very new pl/pgsql.  I get a error
on the very first line of the function.  The function is:

    CREATE FUNCTION testFunction() RETURNS CURSOR AS '
            ....

Is this the correct way?  Could you send me an example?

Thanks in advance


Jose Luis
