[Qgis-developer] Attribute table in Master - 2 issues
1) Updating of values using Field calculator Using master, I select some rows in an attribute table (the data is in PostGIS). I use field calculator to update the values of an existing column in my selected rows. These new values will not display until I close the attribute table and open it again. 2) Row selection (blue highlight) If I click and drag down or up while the mouse button is still held down, I can select multiple rows. These rows are highlighted in blue. If I do this a 2nd time, when I first click the mouse button, the old selection is still shown in the blue highlight. The old selection highlight only disappears when I am finished with my new selection and release the mouse button. This for me isn't the correct behavior that I would expect. However, if you select a set of rows, and then make another program the focused window, if then click back into the attribute table and drag a selection (the action of click and drag has to be the thing that gives the attribute table focus back), it displays the correct behavior I would expect (i.e. the previous selection highlight is removed straight after I have clicked with the mouse button). If I return focus to the attribute table window first and then click and drag, it still displays the wrong behavior. Is anyone else experiencing these problems? I am using Windows 7. Apologies if these have already been reported. Regards, James ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] QEP/RFC sqlite virtual tables
Hi Martin, Thanks for your review. Le 29/10/2014 17:34, Martin Dobias a écrit : Hi Hugo! On Tue, Oct 28, 2014 at 6:15 PM, Hugo Mercier hugo.merc...@oslandia.com wrote: are there other opinions ? Other arguments for one or the other side ? I have to say that initially I was very excited about the idea... and after thinking about the details I am getting less excited as there are probably lots of gotchas. Below there is list of questions in the order of reading the proposal. ** Use cases - item 1 - in what sense the layer would be dynamic? create a dynamic point layer based on X,Y(,Z) coordinates = if points coordinates in the underlying layer change, then their geometries can be updated during the next fetch. Like for example the creation of a point layer from a CSV file with the watch file option. ** Indexes - how will be indexes requested by underlying providers of primary sources? Will you add support to providers to return indices associated with a given primary source? How can sqlite make use of such information? Are you going to replicate the same indices for the virtual tables? Yes we will need something like this in order to properly use indexes of underlying layers. By populating sqlite_stat* tables. And yes I realize that may involve replication of indexes. For the case where more than one index is available on a table, the xBestIndex method of the virtual table mechanism is made for that: an estimated cost can be returned for each constraint - the need to use spatial indices explicitly (with such weird syntax) is not good - this should be done by DBMS, not by the user. In practice nobody will use them and the spatial queries will be slow Yes it is the Spatialite spatial index syntax. ** Serialization - I am lost. Are we going to materialize those sqlite views in memory or to disk? I thought they were meant to be just views wrapping QGIS layers Yes, they are. They can be part of a project file. The second paragraph is misleading. ** Implementation details - regarding QgsVectorLayer constructor: to me it does not look like a case special enough to require a new parameter - what does it mean the provider would be based on spatialite? a subclass of spatialite provider - or a copy of it - or something else? Not decided yet. But it is probably too early in the discussion to go into such details. - are the insert/update/delete triggers going to be provided by user or generated automatically? (I believe it should be automatic) As automatic as possible. But in the general case, it is not possible. Some columns cannot be updated (computed during the query). Or there may be more than one possibility to update a join. - how do we find out that the views from virtual layers are actually editable? If an update trigger is defined. - how do we determine whether the view has a geometry - and in case of multiple geometries, which one to choose? (geometry columns are just ordinary blobs, right?) - how do we determine primary key for a view? (for feature IDs) Good points. We will need to pass these information to the constructor, as it is now with a postgres provider ** Python bindings - how would I create a virtual layer from Python? I would hope to do something like iface.addVectorLayer(SELECT * FROM layerX, virtual) - would that be possible? This kind of syntax (using loaded layer names instead of their explicit definition) is clean but would require : * that layers are already loaded before we can use them * then to save the loading order of layers in the project file The document refers to the use of explicit layer urls. I don't have a strong opinion on this choice. ** User interface - what is the referenced layers box for - is it just to inform user which layers he used? Or does he need to explicitly register those primary layers somewhere? See previous answer ** Performance - how will sqlite plan execution of queries? - inner join of two virtual tables based on attributes? - spatial joins? - does sqlite have access to any statistics of virtual tables and indices? These are quite important for reasonable query execution plans. See answer more on the top: sqlite_stat* tables, xBestIndex - During normal operation when iterating over vector layer there is conversion: backend - QgsFeature. As far as I understand the virtual tables add two more conversions during execution: QgsFeature - sqlite - QgsFeature (first in virtual table implementation, second in new provider implementation). Is that correct? Have you tried to measure additional overhead? Hmmm correct. I did not have any measure yet ... In summary: I have the impression that virtual tables are just a simple way to provide access to external data to sqlite, not an invitation to use sqlite engine with foreign data. The provided API simply does not look mature enough. I would not be too optimistic about
