[Gdal-dev] OGR Attribute filter expression limitation

Hi list,

 

Does OGR support filtering by fields having field names in both side of an
operator such as:

 

(myfield1 > myfield2) and (myfield2 > 0)

 

Both of the fields are numeric.

 

I seems this type of expression is not supported. What restrictions do I
have to take into account then?

 

 

Tamas
