The following example opens the SQLite database "Cities_1000_V4.4.sqlite" and loads the database extension "mod_spatialite4.dll" with the entry point  "sqlite3_modspatialite_init". The example then performs various searches in the database and displays the results in the logfile.

VBScriptPython

 

Call SQLiteOpen(DataReadPath & "Cities_1000_V4.4.sqlite")
Call SQLiteAddExtension("mod_spatialite4.dll", "sqlite3_modspatialite_init")
Call SQLQuery("SELECT Name FROM cities1000 LIMIT 10;", True)
Call SQLQuery("SELECT Name FROM cities1000 ORDER BY Distance(geom_wsg84, MakePoint(cast(12.4876180 AS DOUBLE), cast(41.9029000 AS DOUBLE), 4326)) LIMIT 5;", True)
Call SQLQuery("SELECT * FROM knn WHERE f_table_name = 'cities1000' AND ref_geometry = MakePoint(cast(12.4876180 AS DOUBLE), cast(41.9029000 AS DOUBLE)) LIMIT 5;", True)
