LEFT JOIN tblProdus as p ON lngProdus=lngProdus

Mi se pare mie sau coloanele pentru care faci 'joinul' sunt identice?

o eroare de scriere imic er scuze la aceea egalitate lngProdus=lngProdus am uitat sa scriu a.lngProdus=p.lngProdus de fapt in script e cum am scris acum a doua oara.Eroarea ramane ..

Afisez mai jos tot codul din pagina poate cineva are succes.Eu sincer de 2 zile ma tot uit la el a nu se intelege continuu :) dar chiar nu imi dau seama unde poate fi gresala.Ideea este ca daca in interogare folosesc aliasuri de genul "AliasBazaDeDate.camp" nu imi afiseaza nimic in pagina forma actuala.Daca scot aliasurile imi afiseazadar va dati seama ca am nevoie de ele pt o interogare cu mai multe joinuri.Am luat si varianta sa scot aliasuri, fie mi-am zis dar tot degeaba ca daca folosesc al doilea JOIN nu imi mai afiseaza nimic.

Am gasit.Pentru cei care se vor lovi de asa ceva doua variante am:

$sql= "SELECT .lngTichet,a.lngNumar,a.txtNumarVehicul,a.lngProdus,p.txtNume as numProd,a.lngDelegat,
a.lngFurnizor,a.lngCumparator,a.lngTipLivrare,a.lngTara,a.lngOperatorTara,o.txtNume as numOperator
FROM (tblTichetArhiva a
LEFT JOIN tblOperator o ON a.lngOperatorTara=o.lngOperator)
LEFT JOIN tblProdus p ON a.lngProdus=p.lngProdus";

(sau)

$sql= "SELECT .lngTichet,a.lngNumar,a.txtNumarVehicul,a.lngProdus,p.txtNume as numProd,
a.lngDelegat,a.lngFurnizor,a.lngCumparator,a.lngTipLivrare,a.lngTara,a.lngOperatorTara,o.txtNume as numOperator
FROM tblTichetArhiva as a, tblOperator as o, tblProdus as p
WHERE a.lngOperatorTara=o.lngOperator AND a.lngProdus=p.lngProdus;";
