Python hack (at best) here....
I would like to base a selection on an already selected record in a layer, and can't quite seem to crack that nut. Here is the pseudo code:
Select a record ' in this case a point
Extract the FullStreet attribute value ' it'll be something like S MAIN ST
Add to the selection all other points that have that same FullStreet field value 'seems like a fairly simple operation
I've been trying to do that using an arcpy.SearchCursor within the arcpy window :
>>> cursor = arcpy.SearchCursor("apLayer")
>>> for row in cursor:
... street = row.FullStreet
... arcpy.SelectLayerByAttribute_management ("apLayer","ADD_TO_SELECTION","FullStreet = 'street'")
This runs with no errors but only ends up with the originally selected point as being selected. (See attached)
Questions: is this a case of newbie syntax error?
is there a better approach to do what I intend to do?
