[gdal-dev] RE [Polluriel potentiel] Re: ogr ODBC problem
Thanks Brent for your answer. But view's primary key? I'm missing something here...What do you mean by that? Do you mean a column with a unique id in the view? There is no such column in my view. Is ogr now needs a unique id in a view? Because it was working before I migrate to linux with a recent vertsion of gdal. Also, My problem is before using CONNECTIONTYPE OGR CONNECTION OGRVRTDataSource A simple ogrinfo like this ODBC:username/password@WebMapDSN,v_MyPoints Gives me the error OGR_ODBC: Table ?s???s!.? has no identified FID column.

Re: [gdal-dev] RE [Polluriel potentiel] Re: ogr ODBC problem
Steve, In my case I was getting OGR to get data from a database view, but it could have been a table. I think OGR needs (would like?) to know which column it can use for unque id. I would expect your view (or table) would have a unique key column otherwise relation operations (like joins) can be a problem (the db admin should be able to tell you). Perhaps the ODBC system on Linux doesn't give OGR enough info about the columns to automatically identify the Primary Key column. If you are testing with ogrinfo you could user the -fid option after you've identified the Primary Key column?

for ogrinfo we were using, as explained here, http://mapserver.org/input/vector/VirtualSpatialData.html#steps-for-display ogrinfo ODBC:User/Pwd@mssql__archives msStatut_station2002_2006 That was working on windows Though, That doesn't work on our linux distro linux sles 11 sp1.
