[Qgis-psc] Fwd: [qgis/QGIS-Enhancement-Proposals] Support SAP HANA databases in QGIS (#151)

[Andreas Neumann]

Looks good to me. 

So the first version of QGIS that could potentially ship the HANA
provider would be 3.12 - right? 

How about backporting to 3.10 - would this be an option or not? 

Greetings,
