Hi Dejan,

I don't think it is possible using ogr2ogr.exe, you will need to write a
small programme to do so.

Sorry I have not written any script yet on such a issue. But you could what
you could do is.

Open a recordset and from the desired name in select statement

select [select distinct FIELD1 from SHEMA.TABLE] || [select distinct FIELD2
from SHEMA.TABLE] || 01 from DUAL

and then pass this into the command line parameter as string

to from

ogr2ogr.exe -f "ESRI Shapefile" <string from database result>.shp
"OCI:xxxxxxx/xxxxxxx at dbname" -sql <select queries that you want the output
from >

and execute this thru shell or command prompt.

Hope this helps...!!!

Rgds.
Abhay.
