Re: [Qgis-developer] Spatialite ’select’ stateme nt as vector layer in QGIS

What did you mean? The RT_Sql_Layer permits to load every PostGIS query, not table based only. So I cannot understand, what do you miss in RT_Sql_Layer? Hi Giuseppe, when I pressed 'send' button in my email client I realized, that I need to provide some example. In general, I was failing to load the result generated by PLPgSQL function which had no relation to any existing layer. I can provide some usefull examples by time. Thanks a lot for Your plugins. -- Ivan Mincik, Gista s.r.o. ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] Spatialite ’select’ stateme nt as vector layer in QGIS
Hi all I've added a new version of this plugin (v 0.2). It is now possible to query spatialite and postgis layers. The results are displayed on the map canvas or as a table. I added a small help page to the plugin as well. I started writing some documentation on how to use it, but it is still unfinished. A small gotcha: if you decide to test it with postgis layers, don't forget to include the schema name when you reference a table. Please let me have some feedback, if you have the time to test it out.

Re: [Qgis-developer] Spatialite ’select’ stateme nt as vector layer in QGIS
Hi all In fact, I have a plugin that allows to load custom spatialite queries to the map canvas. I started it as a pet project, to see if I could improve my Qt skills ;) Currently it is really crude. I can make it available at the experimental repository if you are interested. My initial goal was to make something that could be made to work for spatialite and postgis alike. Currently, only the spatialite part works (and just barely). I was trying to make a more stripped plugin, that I could just use to write some SQL and see the results in 3 ways: - directly over the map canvas, creating a temporary layer (that cannot be edited), a la RT SQL style - this already works and it seems to be what you want; - saving a new layer to the database, based on the query, and immediately loading it to the canvas - not implemented (yet); - just making a normal query, without visualizing the results in the map canvas - not implemented (yet).

Re: [Qgis-developer] Spatialite ’select’ stateme nt as vector layer in QGIS
Hi Giuseppe, In PG manager / RT SQL layer, can you do PosGIS ’select’ statement as vector layer in QGIS now?
