umm mengen

Twee DB's met elkaar samen voegen.

Doormiddel van dit script bijvoorbeeld

Beetje raar.. je geeft zelf oplossing al..
Zo niet moet je ze samen mengen in PHPMyAdmin

Ja, die heb ik vannacht gevonden, dus zo raar
is dat dan niet.

Maar hoe doe je dat dan in PHPMyAdmin ??

Uuhm.. tabel bekijken.. kopieeren.. plakken volgens mij..

Dat werkt zo dus niet.
Als je dat zo doet, dan is je DB verziekt

Je moet stuk bij stuk doen..
Bijv. niet alles eronder kopieen maar de members onder de members bij het ene db'tje doen..

Wat moet je met dit code doen?

maak er een php bestandje van bijvoorbeeld merge.php zet het in de root en navigeer er heen.....

@Badja:
Hoe zinloos om heel dat script te quoten, je verneukt hier de topic door die extra lang te maken.

Wat heeft dat mengen als voordeel? Welke twee databases meng je? Zijn dat phpbb databases? Dan zal hoogstwaarschijnlijk de uiteindelijke tabel langs geen kanten werken volgens mij

Jah dit vind ik nou zeer kinderachtig. Je verpest gewoon je eigen topic. Ik geef je geen support aangezien je zo kinderachtig doet. Ga dan ergens anders
