Re: Re: [gdal-dev] question about georaster and python

thanks! but I think that the method you mentioned will depress the performance, for example, when using the python driver.CreateCopy(source, "geor:user/pwd at db,tab,col", <create options>), in fact it will use the gdal_translate function. And the performance of PL/SQL will exceed the gdal_translate. so I want to use cx_Oracle, but I don't know how to use PL/SQL by cx_Oracle.

Example:
 >>> from osgeo import gdal
 >>> driver = gdal.GetDriverByName("georaster")
 >>> source = gdal.Open("example.tif")
 >>> target = driver.CreateCopy(source, "geor:user/pwd at db,tab,col", <create options>)
 >>> target = None
 >>> source = None
That would load the geotiff file to GeoRaster.
