[Qgis-user] Need help with learning Field Calculator.

[Ujaval Gandhi]

Field calculator uses 'expressions' - which are useful across QGIS. I have a
workshop specifically to learn QGIS expressions from the ground up. Check the
workshop at https://courses.spatialthoughts.com/qgis-expressions.html
[https://courses.spatialthoughts.com/qgis-expressions.html] along with the video
at https://youtu.be/x3i9qyFGgcQ [https://youtu.be/x3i9qyFGgcQ]
