Thanks a lot. I haven't got access to the database logs. But method works correct in QGIS 2. I found some differences between pyqgis2 API: https://qgis.org/api/2.18/qgsvectorlayer_8cpp_source.html (QGIS2 :line 2732)
and pyqgis3 API: https://qgis.org/api/2.18/qgsvectorlayer_8cpp_source.html (QGIS2 :line 2732) And one more interesting fact: Working time increase proportionally to the number of user-selected features (Working_time ≈ n*5 min, where n - number of user-selected features). And I still did not find solution this problem. If someone have some idea please share with me. -- Sent from: http://osgeo-org.1560.x6.nabble.com/QGIS-Developer-f4099106.html _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
