[Qt-interest] QSqlQuery using QMYSQL3 instead of QMYSQL

[Christopher Rasch-Olsen Raa]

Hi there,

I have an application that is using the QMYSQL-driver. The 
database-connection is set up with

QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");

and my assumption was that that it would then use QMYSQL as driver. It 
has worked like a charm up until now. Suddenly, I encountered a 
SELECT-query that executed ok, and query.size() reports the correct 
number of rows. However, query.next() fails with the error:
'QSqlError(0, "QMYSQL3: Unable to fetch data", "")'

So the question is now; why on earth is the query using the 
QMYSQL3-driver? That driver didn't support UNION's right?

Help here would be greatly appreciated.
