Hi all, I'm trying to select features of a vector layer using an SQL query and show only selected ones. I used "Query builder" on "Attribute Table" but it's very slow when the vlayer features are a lot (around 200000).
Can someone point me a way to select and show features using an SQL query without opening the Attribute Table, for example using QgsVectorLayer class via python plugin? Thank you very much.
