[QGIS-Developer] Creating QOCISPATIAL driver for QtSql

[Julien Cabieces]

Hi,

Here is how you create a database with the QOCISPATIAL driver
https://github.com/qgis/QGIS/blob/master/src/providers/oracle/qgsoracleconn.cpp#L78

Then, you just have to pass this object to a QSqlQuery object and here
you go!

For the build process of the driver, I think you can try building from the existing CMakeList
in the ocispatial folder, it should do just fine.

Then be carefull that the driver is well loaded by your program. You can
just add it in Qt plugins/sqldriver folder, or define it in qt.conf or
with QT_PLUGIN_PATH (see
https://doc.qt.io/qt-5/deployment-plugins.html).

Regards,
Julien
