[Gdal-dev] SQLite problem
Hi all, I have created a sqlite spatial db with ogr2ogr, starting from a simple shapefile. I'm able to read the proper info of this sqlite db with ogrinfo. If I add a column to this sqlite db inside the table where I have the WKT_GEOMETRY, ogrinfo is no more able to read properly this db. Is it possible to add a column to a sqlite spatial db without destroy the spatial component? I'm using SQLite Manager 0.3.15 for firefox to edit the db. I'm attaching the original sqlite file: http://www.nabble.com/file/p20233548/output1.sqlite output1.sqlite Thank you, Andrea - Andrea Borruso email: [EMAIL PROTECTED] blog: http://blog.spaziogis.it -- View this message in context: http://www.nabble.com/SQLite-problem-tp20233548p20233548.html Sent from the GDAL - Dev mailing list archive at Nabble.com. ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
Re: [Gdal-dev] SQLite problem
This must be a problem with your SQLite client. I used the sqlite3 console gui and did on your database: ALTER TABLE output ADD COLUMN newcolumn VARCHAR; ogrinfo was still working afterwards.

Can you provide an example that ogrinfo can't read? Generally, adding new columns to a spatial table should not cause problems for OGR.

Yes, see http://www.sqlite.org/lang_altertable.html You need SQLite 3.1.3 Le Wednesday 29 October 2008 23:44:37 Even Rouault, vous avez écrit : I can read output2.sqlite with ogrinfo: INFO: Open of `output2.sqlite' using driver `SQLite' successful.
