I am having trouble populating Points layer "FacltyType" field with the selected layers CPUC field.
I need to able to select multiple points from the Points_2 layer then select by location on the Points layer by using the SelectLayerByLocation. Then i need to update the "facltyType" field of Points layer with the selected Points_2 CPUC field.
If the Points_2 layer CPUC filed has "DWELL" i need the Points layer FacltyType field to populate as "Home", if it is NULL i need the FacltyType field of the Points layer to populate as "MobileHome"
My current code tempt makes a permanent Join between Points and Points_2 on the TOC. Is there a way on how to make a temporary Join then populate as i mentioned? Also the current code just populates the "FacltyType" with DELL, but i need to do as i mentioned above.
I tried making a feature layer in_memory but i got the following error:
Runtime error Traceback (most recent call last): File "<string>", line 33, in <module> File "C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\management.py", line 5357, in JoinField raise e ExecuteError: Failed to execute. Parameters are not valid. ERROR 000732: Input Table: Dataset PointsLyrA does not exist or is not supported ERROR 000732: Join Table: Dataset Points2 does not exist or is not supported Failed to execute (JoinField).
Any code help would be great.
Thanks.
