Hi all,
 I'm trying to convert a SHP file to GPX via ogr2ogr.

The "default" conversion works well:

<http://www.gdal.org/ogr/drv_gpx.html>$ ogr2ogr -f GPX nome_file.gpx nome_file.shp

I'd like to mantain two attributes and I tried the option GPX_USE_EXTENSIONS=YES with sql instruction to rename the interested fields:

$ ogr2ogr -f GPX -dsco GPX_USE_EXTENSION=YES -sql "SELECT NOME AS name, CAT AS desc FROM source_layer" nome_file.gpx nome_file.shp

but I get this error:
--------------------------------
ERROR 1: SQL: Missing comma after column NOME in SELECT statement
--------------------------------
It seems that I forgot a comma but this command is the same in the documentation.

I've checked the syntax with the help of this doc:
http://www.gdal.org/ogr/drv_gpx.html
http://www.gdal.org/ogr/drv_vrt.html

but I don't understand where is the error.
Does anibody have similar experience?

Flavio,

I found the above syntax worked in trunk, and 1.6 but not in 1.5.  I suspect
you are using 1.5.x or earlier binaries that do not support the AS operator
for renaming fields.

Best regards,
