Description
Hi, a user raised a nasty bug here on qgis 2.2:
when filtering (right click on the layer) a file layer (tested shp, tab and postgis), if typing an expression like
"MyField" = 'MYFIELD'
then no filter is applied.
Case seems unrelated, I have also tested with another datasource where "myfield" = 'MYFIELD'
In Master and 2.2, '!=' and '<>' , and 'not like 'MyField' are affected.
Marking it as a blocker since this can be really misleading, and user may not be aware of it.
Cheers
Régis

This is done by the data provider. Which data source are you using, this might be a OGR bug.

Hi Nathan, shp and tab tested. I joined a shapefile sample if you need to reproduce.

Yeah I think this would be a ogr issue because it just passes the query as a -where arg.

You're right,
tested
ogrinfo -al -geom=NO -where "TPME = 'GME'" F:\\temp\\bug_qgis_filter_fieldname.shp
and the bug is here...
I open a ticket in gdal ogr tracker
Thanks

So this doesn't apply to the postgres provider (with estimated metadata turned off)?
