Hi,
For an existing layer I would like to add/change/remove the WHERE
filter by script - the same that one would normally set by the query
builder.
Do I need to change the QgsDataSourceURI() of that QgsVectorLayer and
then reload it or is there an easier/more elegant way to change the
filter of an existing layer?
Thanks if you have any ideas or even sample code on how to achieve
this.
Andreas
