problems with a select query in informix

hello, I got a problem, and I think it has to do with my low knowledge about how php treats arrays. What I do is this: 1) I do an insert to the articulo table with some data. 2) I run the hack below to read the biggest integer in articulo.a_id for later use. articulo.a_id is a SERIAL. $q_id_identi=ifx_query("SELECT MAX (a_id) FROM articulo",$conn_id); $q_ar_identi=ifx_fetch_row($q_id_identi); echo(sprintf("<br> %d <br>",$q_ar_identi[a_id])); The problem is that the echo you see above give me 0. But if I make the query directly in dbaccess (an informix program which lets throw querys) and the answer is diferent.
