EditStrategy, how to save data

[JeanC]

This actually executes the query twice.

Ah thanks.

What does qDebug() << query.lastError() output? What does db.isOpen() and db.isValid() return? Do you get any errors if you issue an invalid query? Do you start any transactions?

I'm gonna investigate.
Oddity I noticed is that I can edit data with phpmyadmin, but the Mysql Query Browser has al edit options greyed out if I right click on a cell.

Then maybe you don't have rights to modify the database?
