[Qgis-developer] question about ogr provider

[godofredo contreras]

Thank you Martin for your answer. I made a program
to test what capabilities is the mysql ogr driver reporting
and it only reports: 

Random Read.
Fast Spatial Filter.
Fast Feature Count.

But there have to be something wrong with the driver capabilities report
because in the same test program I use CreateFeature and it works
but it is not reporting Sequential Write.


Regards
Godofredo Contreras
