tableInfo: tablename is empty string when using db function

Hi, I'm (actually, sql2xml) is using tableInfo to get result metadata on a query: SELECT CONCAT(party.first_name, ' ', party.last_name) as name, organization, role.name as roles, party.active as active_status FROM party, role, party_role WHERE party.id = party_role.party_id AND party_role.role_id = role.id The CONCAT that generates the first field somehow causes tableInfo to give the table name for that field as "", instead of "party". This royally screws sql2xml, as you might expect. I'm sure it's the CONCAT that's causing trouble, as I tried it without and got the expected results. Is this a bug, or is tableInfo just not usable when there's a db function in the query? Anyone know of any workarounds? Thanks, James
