Re: [Qgis-developer] a SQL console as new feature
There is a new plugin - a console, Fast SQL Layer for QGIS.

Re: [Qgis-developer] a SQL console as new feature
Not really what Simon is getting at. I guess not many people on here are MapInfo users as well. MapInfo's SQL allows you to query any datasource using SQL, so you could do Select * From table1,Table2 where table1.comecolumn 10. Where table2 is a shape file and table1 is a tab file. @Simon Yes I think you could do it via a plugin although I'm not sure how it would go on speed. And stuff like this should really be built into the program. I'll investigate the plugin route if only as a prototype. - Nathan On Tue, Jun 14, 2011 at 9:18 AM, Noli Sicad nsi...@gmail.com wrote: There is a new plugin - a console, Fast SQL Layer for QGIS.

I'm going to check out the code for uDig to see how they have done it and see if something can be done like that in QGIS. http://udig.refractions.net/confluence/display/EN/Common+Query+Language Hi Nathan in QGIS we have something similar, maybe not that advanced: look for QgsSearchString and QgsSearchTreeNode classes. They were originally created for advanced search in the attribute table supporting a subset of SQL, more recently it is possible to use those classes also for evaluation of expressions.

Re: [Qgis-developer] a SQL console as new feature
Tim, One step but not exactly what Simon is referring to IMO. In MapInfo you have a layer of SQL that you can run on any data type, eg Select * From A,B WHERE a.obj intersects Bobj A can be a native MapInfo table and B can be a shape file that you have opened, or a csv or anything. This gives the user a lot of power to join anything to anything and not just on data but spatially. This is more what Simon is talking about IMO. I think it can be done in QGIS just the hardest thing is supporting all the different providers, but this SQL would another layer above what is already there and would really only have to talk to QgsFeature and QgsGeometry as they have everything it needs. - Nathan On Wed, May 25, 2011 at 6:20 AM, Tim Sutton li...@linfiniti.com wrote: Hi On Sun, May 22, 2011 at 3:22 PM, Simon Georget simon.geor...@gmail.com wrote: Hi list, Firs,t many thanks to all developers and qgis contributors.
