Time to update ... 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?
