In Debian and Windows system I have the same problem. QGIS first says the follow message and then it crashes.

Problema nell'inserimento di elementi dal file: /home/Documenti/Gis/Cartografia/Arezzo/uniti/10k/AU.shp The database gave an error while executing this SQL: SELECT AddGeometryColumn('corso', 'AU', 'the_geom', -1, 'POLYGON', 2) The error was:

relazione "corso.AU" non esiste

CONTEXT: SQL statement "ALTER TABLE corso."AU" ADD COLUMN the_geom geometry " PL/pgSQL function "addgeometrycolumn" line 86 at execute statement SQL statement "SELECT AddGeometryColumn(, $1 , $2 , $3 , $4 , $5 , $6 )" PL/pgSQL function "addgeometrycolumn" line 4 at SQL statement

comment:2 by leo.lami, 15 years ago

Don't considere the last change. The reported problem is due to the all caps name choosen for the PostGis table.

comment:3 by msieczka, 15 years ago

Hmm. Same happens in QGIS 0.8.1. In both 0.9.x and 0.8.1 SPIT crashes, whatever shapefile I'm trying. Shapefiles are OK - QGIS can read and manipulate them.

I can import same shapefiles with ogr2ogr. Eg. a command:

ogr2ogr -f PostgreSQL PG:"dbname=dss_postgis port=31268" -lco "DIM=2" -nln gminy -a_srs EPSG:32633 caves_gminy.shp

works OK. QGIS can see the resultig PostGIS layer, lets me query it etc.

Could be a different bug, here is the bt (version 0.9.2 on gutsy 64 bit):

Given the frequent problems with the SPIT plugin, I think a different approach would be better:

  • replace ogr2ogr within the current SPIT plugin with the more robust shp2pgsql (please note however that this would impose a dependency on the client side of PostGIS), or
  • replace the current SPIT with a new plugin, possibly in python, as a thin wrapper to shp2pgsql

i use the qgis in windows XP ,I AM USING the chinese type character set (tranditional),in my region,we use big5 and UTF8 code in our language,when i use the SPIT PLUGIN to import a shapfile with a chinese file name or chinese path name,after i push the "OK" button in the bottom-right area of form,the form frozen,after few secondes,the QGIS APPLICATION crash,and the MS-windows ERROR report dialog appear,before i PUSH the ok button,i add the shapfile,and the file instance in the workarea appear it's filename and path in the quene,but after i push the ok button the qgis crash,i can add a shapfile with a chinese file name or path in the add vector layer function,but when i use the SPIT to import the shapfile to POSTGRESQL/POSTGIS,it crash

Thanks for confirming the bug on Windows. Please take more care when you modify the ticket's fields in future though. I've fixed it this time.


comment:9 by leolami, 15 years ago

It seems resolved in 0.9.2 Can you control and close it?

comment:10 by msieczka, 15 years ago

What do you mean by "it seems". Have you checked it?

For me SPIT still crashes when I press OK. And a probably related bug #903 is still present too.

Checked in the latest 0.9.2 SVN trunk r8210.
