Hello group, I've added a WFS-layer to a project try to define filters on different attributes. It seems not to be possible to filter for NULL values.
Example: * 1932 records in total * 376 records with a value in a date attribute * 20 records with 2005-12-31 as value If I set the filter to "end_date" = '2005-12-31' the result is 20 records. If I set the filter to "end_date" != '2005-12-31' the result is 356 records. So only records that have an end date are recognized. Record with NULL as end date are ignored. Filtering in the attribute table with "is_empty_or_null" works but only for selection. Is this "normal" behaviour with WFS layers or is there a way to define a filter string that work for all records? QGIS-Version is 3.40.4-Bratislava Best regards Michael ***************************************** Michael Reetz Datenbanken und Anwendungsentwicklung Nationalpark-Verwaltung Niedersächsisches Wattenmeer Virchowstr. 1 | 26382 Wilhelmshaven Tel.: +49 (0) 4421 911 291 e-mail: [email protected]<mailto:[email protected]> Web: https://www.<https://www./>nationalpark-wattenmeer.de [cid:[email protected]]
