Make sure that your second query is returning only one row, if it dont help, try this: $query="select email from usuarios where userName in (select username from fussv where folio = 'FUSS-130-2006')" MySQL think that you second query returns more than 1 row, that's why mysql dont accept your query, is like trying to compare vs more than one scalar value Regards! +----------------------------------------+ | Ing Edwin Cruz <ecruz@xxxxxxxxxxxx> | +----+ | Transportes Medel Rogero SA de CV | | | | Desk: +52 (449) 910 30 90 x3054 | +----+ | MX Mobile: +52 (449) 111 29 03 | | Aguascalientes, Mexico | | http://www.medel.com.mx ; | +----------------------------------------+ > -----Mensaje original----- > De: Miguel Guirao [mailto:miguel.guirao@xxxxxxxxxxxxxxx] > Enviado el: Jueves, 28 de Septiembre de 2006 09:09 a.m. > Para: php-db@xxxxxxxxxxxxx > Asunto: SQL query > > > > > Hello list, > > Whats wrong with my SQL query: > > $query="select email from usuarios where userName = (select > username from fussv where folio = 'FUSS-130-2006')"; > > I get an error! > I have tested the two individual sentences and they worked OK! > > --------------------------- > Miguel Guirao Aguilera > Logistica R8 TELCEL > Tel.
