Schrijven van SQL-query's niet mogelijk
Ik hem een probleempje ik wil graag via een SQL-query schrijven naar een mysql server. Nu heb ik het schript wel gevonden maar het werkt niet.
Ik krijg geen fout melding maar het lijkt er op dat er gewoon niets word uitgevoerd. Maar als ik bijvoorbeeld een verzoek vraag van "SHOW DATABASES" dan geeft hij niet weer. Weet iemand wat ik fout doe?
Ik heb het schript hieronder geplaatst:

Volgens mij krijg je dan te zien dat $query nooit gemaakt is, of ben je vergeten om die in dit script te zetten?
Maar in ieder geval bedankt.
