Okay, once I updated to 7.2b5, that select statement started
working just fine for me. :)
Though I have hit another problem, if I want to display multiple
fields from the returned row, the function executes again for each
field. I.e. 'SELECT id(update_get(1), fielda(update_get(1), ...' will
result in both the values for id and fielda being displayed, but will
execute update_get() twice. This is not only inefficient, but also
undesireable (esp if update_get() modified something that was only to be
modified once for a single row reterival).
So, how do I get back and access the entire row returned from a
function without calling it multiple times? Or is that even possible?
Thanks.
