Re: Error with returning SETOF Record

I guess the question I have then is how do I return data from a select statement using the record datatype? This is only a test function I was trying to get info from, but my application is based on passing the table name to the function dynamically. How do I do this? The documentation is sketchy when it comes to the record datatype.

TIA
Alex

That's pretty much what I'd expect, unless table visaapplicants contains
only a single varchar column. The example works fine for me if I define
visaapplicants that way.
