I am trying to add a PostGIS layer, but I get an assertion violation. I enabled QGISDEBUG and got the output (edited for space) shown below. The layer query is just a reference to a view (no WHERE clause), and that view depends on other views, among them "public.es_attendance". This view has a column, PROJ0, which is defined as SUM, where P is the table public.planning2006.

public.es_attendance.esproj2 <- public.planning2006.esproj2 is a 'r' of type numeric
public.es_attendance.ksproj2 <- public.planning2006.ksproj2 is a 'r' of type numeric
Searching for the column that public.es_utilization.proj0 refers to.

Does this problem still occur with later versions of qgis?

This bug has been reported before (#136), and was resolved by SVN 1d4d6377 (SVN r5573), which also changed the error message from that reported above to something more informative.

Could you try loading your view with a 0.8 preview release because if the problem still occurs, the changes in 1d4d6377 (SVN r5573) will give more clues as to what is going wrong.

#2 Updated by Gavin Macaulay - almost 14 years ago

  • Resolution set to fixed
  • Status changed from Open to Closed

This problem will have gone in 0.8 versions of qgis. In conjunction with the fix for ticket #277, this problem is fixed.
