niphlod I'm having a problem with left with AND. this is the sql I want to work: SELECT * FROM permissao_grupo LEFT JOIN auth_membership ON auth_membership.id_permissao_grupo = permissao_grupo.id AND user_id =3 WHERE permissao_grupo.id_grupo =5 this is what i tried until now: db((db.permissao_grupo.id_grupo==grupo)&(db.tipo_documento.id==db.permissao_grupo.id_tipo_documento))._select(left=((db.auth_membership.on(db.permissao_grupo.id==db.auth_membership.id_permissao_grupo))&(db.auth_membership.user_id==usuario)))
but i got this error: <type 'exceptions.TypeError'>(unsupported operand type(s) for &: 'Expression' and 'Query') What I need to do?
