Answer 1

You're mixing old-style and new-style joins. Should be something like:

SELECT emissaogrd.dataEmissao, grd_dados.grd, documento.numero
    , emissaogrd.revDoc, recebimento.nome, grd_dados.usuariogrd 
FROM documento 
JOIN emissaogrd
    ON emissaogrd.idDoc = documento.id  
JOIN grd_dados 
    ON emissaogrd.idgrd = grd_dados.grd 
JOIN recebimento  
    ON emissaogrd.idgrd = recebimento.grdId 
WHERE recebimento.entregue = '0' 
ORDER BY grd_dados.grd DESC, documento.numero;
