monks, please advise

$stm = "insert into glossary (term_id, definition, state) 
       values (seq_document_id.NEXTVAL,?,?) returning term_id into ?";
$sth = $dbh->prepare($stm);
$sth->execute($rows->[$num][1], state($rows->[$num][2]), $value);
die unless ($value);

the statement inserts into the db, but returns a null value to $value. From querying the db, i know that term_id is being successfully updated with seq_doc_id.NEXTVAL, but for some reason the 'returning into' part does not want to behave, and keeps giving me null values. what am i doing wrong?

UPDATE: Thanks for the advice, folks. Found out the resolution. The best way to do it was to use

$sth->bind_param(1,$variable)
$sth->bind_param(2,$variable)
$sth->bind_param_inout(3,\$value,max_length)
$sth->execute();

thanks to ruzam for clarifying that execute() is a one-way communication channel, that was the key for me to find the solution. much appreciated
