comment Is there a way to use gdal functions from OSGeo4W out of their shell?
So for example, in OSGeo4W if you type gdal_merge nothing comes up? You should see something like this: Usage: gdal_merge.py [-o out_filename] [-of out_format] [-co NAME=VALUE]* [-ps pixelsize_x pixelsize_y] [-tap] [-separate] [-q] [-v] [-pct] [-ul_lr ulx uly lrx lry] [-init "value [value...]"] [-n nodata_value] [-a_nodata output_nodata_value] [-ot datatype] [-createonly] input_files [--help-general]

Sorry Paul, I didn't know you were filling something in. If you want to add the answer back up, I am sure others would find it useful. I do understand the meaning of GROUP BY; this example doesn't properly show my example. But thank you for your help.

Thanks, that worked. Do you have any idea why it would need a uid / gid? I haven't needed to do this with other databases.

When I perform a similar query in Spatialite I do not see this issue. What I am looking for is all the city names that have a city_abbr of nyc. I want to make sure I only get one return if there are cities that share the same city name. I understand distinct will give me this result, but I don't understand why GROUP BY needs to have all the columns that are identified in the SELECT.
