[Qgis-user] Problem filtering table on columns with NULL values

[Bernd Vogelgesang]

Hi,

just hit a problem when working with a table from an .ods file.

To work with the data, I have to exclude some values from a field, where
some entries also have NULL values.

When I now filter on the value I do not need ("field" != 'xyz'), also
the rows with  NULL values in that field are filtered out, which is not
what I want.

As I do not want to "invent" data for those rows just to make it work, I
wonder if this is a bug or if there is a workaround for this problem.

Cheers,

Bernd
