[gdal-dev] OGR: How to access Coded Value Domains in File Geodatabases?

[Stefan Keller]

Hi Mike

Thanks! That ticket is very insightful.

I'm not sure though if there is already an agreement there about the
best solution inside OGR code.

In the meantime: Am I correct that there's an immediate solution by
defining an query against table DipCategories of a FileGDB file with
ogr2ogr (-sgl "select ")?
