Hi, I wrote example PLPGSQL function, which demonstrates the case where I was not able to load query using RT SQL Layer. Now it works perfectly. So, hats off and thanks You a lot for Your work. For reference, my test function is attached in this email. Ivan DROP TYPE testtype CASCADE; CREATE TYPE testtype AS (gid integer, the_geom geometry); CREATE OR REPLACE FUNCTION test_function() RETURNS SETOF testtype AS $BODY$ BEGIN RETURN QUERY SELECT 1 AS gid, '010100F03FF03F'::geometry AS the_geom; END; $BODY$ LANGUAGE plpgsql VOLATILE; -- run 'SELECT * FROM test_function();' ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

Hi all > But after upgrading to v. 3.0 I get following traceback when trying to > load every query in PostGIS (for example: SELECT * from schema.table). I uploaded v 0.3.1 that (hopefully) fixes the bug you are refering. I will think about adding Noli's feature requests, which seem reasonable enough. My initial plan was to have a quick'n'dirty plugin to query databases, while we waited for a great postgis/spatialite-super-manager! so I am reluctant to add too much to this plugin. I would like to polish it a bit more though. One thing I'd like to implement is having the plugin's window to be modeless, so that it becomes possible to add and remove layers from the map canvas without having to close the window. -- ___ ___ __ Ricardo Garcia Silva ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

Re: best.Re: [Qgis-developer] Spatialite ’select ’ statement as vector layer in QGIS
Hi Ricardo, Nice plugin. One suggestion, I think it would be good to add "Table" in the tab so we can see the attributes of the table we want to queries and manipulate. Query - Table - Result You can lift / copy the codes from Spatialite Manager and PostGIS Manager plugins. You can probably put a check box as well for the Spatiial and PostGIS in the "Table" as well. The "Preview"? It is one o you if you want to include it as well :-). Thanks.

Hi Ricardo, nice plugin. For me the best feature is that it is possible to load and visualize every PostGIS query, not only queries based on real tables (this is what I miss in perfect 'RT_' plugins). But after upgrading to v. 3.0 I get following traceback when trying to load every query in PostGIS (for example: SELECT * from schema.table).

Re: best.Re: [Qgis-developer] Spatialite ’select ’ statement as vector layer in QGIS
Hi Paolo, all Uploaded a new version (v0.3) of the 'Custom DB query' plugin. I've added it to the 'database' menu. Also, it is now possible to save the result of the SQL query as a new table in its corresponding database. So, to summarize, you can run SQL queries over postgis or spatialite databases and get the results: - in a table view - as a 'real time' layer displayed over the map canvas - as a new table, that gets saved to the database and is immediately loaded to the map canvas It is still pretty raw, so I'm keeping it in the 'experimental' section, but it seems to work OK with my small test datasets. -- ___ ___ __ Ricardo Garcia Silva ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
