# 1062 - Doppelter Eintrag für Schlüssel PRIMARY

Question

Ich verwende CodeIgniter auf meiner Instagram-Mitgliedsseite.

Wenn ich versuche, für das erste Mal in meiner Seite einzuloggen es die id in Datenbank einfügen, aber wenn ich abzumelden und meine Session löschen, und versuchen Sie es erneut einzuloggen, bekomme ich einen Fehler:

internal server error

Das ist mein Protokollfehler in CodeIgniter:

     } 
     $this->output

     ->set_output($ret); 
    else: 
     redirect(base_url());

} 

So, wie die Abfrage nicht dupliziert zu machen?

Answer 1

Falsche Integer (1962377392), weil die Strukturen zu klein int() in Ihrer Datenbank, ändern int()-VARCHAR(128)

Answer 2

Es passiert nur, wenn das automatische Inkrement nicht auf die Primärschlüsselspalte angewendet wird. In diesem Fall sollte Ihre Primärschlüsselspalte automatisch inkrementiert werden. Überprüfen Sie einmal in Ihrer Datenbanktabellenstruktur, um von diesem Problem zu überwinden.
