[Qgis-user] pyqgis - adding an ogr vector layer and setting where clause

[Duarte Carreira]

Hi,Germán. I found that just a few hours before I saw your email.

Turns out it doesn't work with the ogr sde driver. It does work with shapefiles though...

Thanks anyway.

Hi Duarte,

have you tried this?

vLayer.setSubsetString( "id = 5" )

where vLayer is your vector layer object and id is one of the field names in the table.

Germán

Hi there.

I would like to add a layer from an ogr source, and apply a -where option. How can this be done in QGIS through the python API?

I have seen examples of setting a uri string and using addvectorlayer. But this doesn't set a query.

Thanks,
Duarte
