Hi Harrissou, Indeed this is the dialog that you got when you had a WFS layer in earlier versions like 3.16: https://docs.qgis.org/testing/en/docs/user_manual/working_with_vector/vector_properties.html#id14
But now you get the SQL Query Composer (see screenshot) To see, get the 'provincies' layer from WFS: https://geodata.nationaalgeoregister.nl/bestuurlijkegrenzen/wfs and in legend click 'Filter', which (and that's my point) is very, very technical for average users (I think). https://docs.qgis.org/testing/en/docs/user_manual/plugins/core_plugins/plugins_db_manager.html#working-with-the-sql-window is another one but that one IS for databases, while the 'FILTER' was just for simple filters...

I'm not aware of any removal of this kind of info in the docs in the recent years. From the layer properties, Source tab, Query builder dialog (or ctrl+F), I can still access https://docs.qgis.org/testing/en/docs/user_manual/working_with_vector/vector_properties.html#query-builder. Is that one you were looking for? (OK, not really SQL but if the user accepts to first load the layer, this should address most of the cases). There's also the SQL filter from DBManager (https://docs.qgis.org/testing/en/docs/user_manual/plugins/core_plugins/plugins_db_manager.html#working-with-the-sql-window) whose features, from my understanding, are meant to be brought to the Browser new SQL builder. Just not yet finished... Regards, Harrissou
