[Gdal-dev] Oracle OGR Segmentation Fault

[Wim Blanken]

Hello Frank,

Thank you for your answer. I think I found the problem. The Layers I tried
to access didn't have a gid at all. I used ogrinfo with a layer that was not
imported using ogr2ogr but had a gid. This layer worked allright. So i think
ogr wants a gid with a unique record number.

Regards,

Wim Blanken
