arcpy.management.Copy to In Memory Error

Bryan_bsc — Wed, 11 Sep 2024 01:25:03 GMT

Does anyone know if arcpy.management.Copy is meant to be the same as arcpy.CopyFeatures_management? It appears to be the same unless I use it to copy features to memory in which case it gives the following error.

ERROR 000979: Cannot copy between different workspaces.

Example code is below:

fc = r"gisdata.sde\GIS.GISDATA.assets\GIS.GISDATA.plots"

arcpy.CopyFeatures_management( fc, r"memory/in_memory_temp_file") # This works with no errors

arcpy.management.Copy( fc, r"memory/in_memory_temp_file") # This gives the error above

Any help would be appreciated.

Thank-you!

interesting, sounds like a variant of...

BUG-000167752 for ArcGIS Pro (esri.com)

I believe the Copy tool is the geoprocessing version of a catalog copy/paste operation, and copy/paste doesn't support going from a geodatabase workspace to a non-geodatabase workspace.

Well why not? So weird

I can only speculate, maybe it's because it's "lossy"? You lose attachments, relationships, that kind of thing, so you have to use a tool from the conversion toolbox instead.

I have for sure seen that memory is not a full GDB. For example certain SQL functions do not work. Not documented anywhere that I have found so its a hunt and peck which can drive you nuts.

Yup, even very basic GDB stuff like domains aren't supported if I remember correctly.
