How can i start the edit session for a layer warehoused in a geodatabase

[OLANIYANOLAKUNLE]

This is the runtimeerror i get anytime i try to start an edit session for my layers warehoused in a geodatabase;

>>> edit = arcpy.da.Editor(mxd) Runtime error  Traceback (most recent call last):   File "<string>", line 1, in <module> RuntimeError: cannot open workspace >>> 

Please how can i overwhelm this problem of mine? Thanks

Instead of "mxd" , you want to put the full path of the geodatabase

Here is an example:

gdb = r"C:\AllMyLayers.gdb" edit = arcpy.da.editor(gdb) edit.startEditing()      #you may want to adjust the parameters here.  You can read up on the documentation  ---whatever you want to do in your editing session  edit.stopEditing()     #again, you may want to adjust the save parameter.

I want to pass the selection query below for a layer in my Geodatabase, how can i get i to be like the second query, the 1st 1 is not working;

arcpy.SelectLayerByAttribute_management("Parcels", "NEW_SELECTION", '"TDPDetails"' + "=" + "'" + selection + "'")

arcpy.SelectLayerByAttribute_management("Parcels", "NEW_SELECTION", [TDPDetails] + "=" + "'" + selection + "'")

How can i replace "TDPDetails" with [TDPDetails]?

Thanks

Runtime error 
Traceback (most recent call last):

Hi, I'm using Addin Assistant to make a button that will cycle edit sessions but I see that ArcPy wants the exact location of the GDB... Can I use a variable or function to pick up the layers that are visible so the user can cycle through those? They could be anything, anywhere... SDE, FGDB, PGDB etc...


Thanks,
Gregg

What you want is likely an 'Editor' object
