Kvērija daudz daudz OR'i

Vai tas nekas, ja man kvērijā ir daudz OR'i? Nu teiksim, līdz pat 50 :)

 

Vai ir kāds labāks veids, kā panākt to pašu efektu?

 

(Man vajag update'ot ierakstus ar konkrētu vērtību kuriem id ir kāds no sarakstiņa(php masīvs).

Īsāk to var pierakstīt ar IN.

$ids = array(1, 2, 3, 50, 1251);
$query = "SELECT * FROM Tabule WHERE id IN (" . implode(",", $ids) .")";

 

To, vai tas ir potenciāla performances problēma, tev izskaidros EXPLAIN keywords.
