I have three layers from three diferent database tables. When I click in other layer I want to change (with an action) the query of that three layers.
How can I do that? Thank you
You could probably write a python plug in to do this, but as Alexandre Neto mentioned, you would have to be more specific as to the data you are working with. The type of layers? What sort of query are you running? How do you see the query behave when applying to the other layers? Please try to be more specific with you questions in order to get the best response. What you have asked can be open to interpretation which makes it more difficult to answer.
