Nyall Dawson	89b9b67974	Handle type conversion failures for compiled expressions	2015-12-10 20:49:17 +11:00
Nyall Dawson	26f7683cf5	OGR expression compiler fixes ... - Allow simple operators as supported by OGR (+, -, * ) - Only return a partial compilation success if expression contains "column"="column2". Since OGR SQL performs case insensitive comparisons, we need to double check the result using QGIS' expressions to ensure that case matches. Add unit tests for this to provider tests.	2015-11-18 06:30:42 +11:00
Nyall Dawson	f9917b55c3	Remove expected failure from shapefile provider unique values test ... Failure was caused by GDAL bug #6020, which has now been fixed in GDAL. It turns out the values are only incorrect if the first feature in the file has a null value, so I've rearranged the features in the reference shapefile to avoid this.	2015-07-12 19:55:54 +10:00
Matthias Kuhn	afc3996f6c	Add shapefile provider tests ... + Fix OGR provider so it does not return features without geometry when filtering with a FilterRect	2015-05-22 21:03:47 +02:00
