[postgis-users] Identifying field names in select out of order

[Sean M. Montague]

Thanks Don,

I am using php. Problem with pg_fetch_assoc() is that I need to know the
field name.  I want to be able to get the field name regardless of the
order I select them in the select statement.

Are you using PHP?  

You really want to use pg_fetch_assoc() which returns the row in an
associative array.  Similar methods exist in the Perl libraries as well.

This is PostgreSQL specific question. I'm iterating through my selection
and need to get the field name of my data[$i] where
$data=pg_fetch_row($result, $i). I've tried pg_fieldname($result, $i),
but the problem is that the field names in the select statement are not
in the same order as the db, so pg_fieldname(result, $i) is not the
filed from which data[$i] is drawn from.  Is there another way of
determining which field data[$i] comes from regardless of the field
order?  Thank you.

Sean
