Sprawdzenie kolumny getInstance();


Szybkie pytanie

potrzebuje sprawdzić w PS 1.7 czy dana kolumna istnieje, jak najprościej to zrobić?

Jeżeli kolumny nie ma to sypie mi błędem: Unknown column 'mojaKolumna' in 'field list'

a chciałbym aby gdy jej nie ma to echo 'nie ma';


Mój kod:

$add = Db::getInstance()->getValue("SELECT mojaKolumna FROM pr_orders WHERE id_order=".$order->id);

if ($add) {

echo 'nie ma';

} else return false;

Spróbuj w ten sposób: SHOW COLUMNS FROM `nazwaTabeli` LIKE 'nazwaPola'
