[Qgis-user] Problem CRS to data base Oracle

[Julien Cabieces]

Hi,

I'm pretty sure this is the same issue than this one:
https://github.com/qgis/QGIS/issues/37898

Long story short, Oracle definition for projection differs from PROJ
database ones. So this exception needs to be taken care of. It's done in
PROJ > 7.1 but QGIS 3.16 and 3.18 relies on PROJ 6.3.2.

When QGIS will be built with PROJ 7.2 or greater (QGIS 3.20 maybe?), il
would be OK.

But for now, you just have to wait (or build a QGIS 3.18 with PROJ 7.2,
not an easy task).

Regards,
Julien


> Hello,
>
> We are having a problem displaying our data from our Oracle database.
> Our data stored in our Oracle database has the EPSG code as a projection: 2154.
> We have configured Qgis with the following parameters:
>
> - Project CRS: EPSG 2154: RGF 93 / Lambert-93
> - Layer CRS: use the project CRS
>
> Despite this setting, when we load a layer from our database, it loads but it does not appear on the screen.
> To visualize it, we must modify the CRS assigned to the layer by selecting:
> - the project CRS: EPSG 2154: RGF 93 / Lambert-93.
>
>
> By default, it is indicated RGF93 / Lambert-93.

> Why does QGIS not recognize the projection of our data in the new versions (3.16.5 or 3.18)?
> Knowing that in version 3.4 we layers opened perfectly without modifying the CRS assigned to the layer.
