Dear all, I'm developing a Processing Model and I want to run an algorithm (Union) on a specific PostGIS layer. The idea is to have this input layer hardcoded to the Union algorithm.
If this layer is stored in a system file (SHP, or any other vector layer format), it is simple, just pointing Union input field to that file. But as it is stored in PostgreSQL, I thought to use "PostgreSQL execute and load SQL" algorithm to call the layer and use it in Model, as input to Union. In fact this works well, but when running the Model, the PostGIS layer is loaded to QGIS canvas. I think this is happening because "PostgreSQL execute and load SQL" won’t create any new layer, and load the PostGIS layer itself, as a result of the query, just like it's explained in the docs: https://docs.qgis.org/testing/en/docs/user_manual/processing_algs/qgis/database.html#postgresql-execute-and-load-sql So, anyone have any hint to call a PostGIS layer and use it as hardcoded input to a Model algorithm, without python coding? Thank you very much! Best regards, Pedro Venâncio
