Hi folks,
I'm having an issue with an SQL statement for the select layer by attribute function and I can't figure out what's going on, because it worked perfectly on a smaller dataset, but when I try to run it on a larger selection of data it fails and gives me an error. Here is the offending piece of code:
for key in matches:
arcpy.SelectLayerByAttribute_management(wellsFL, "NEW_SELECTION", "U_ID = {}".format(key))
select_id = tuple(matches[key])
arcpy.SelectLayerByAttribute_management(orpsFL, "NEW_SELECTION", "U_ID IN {}".format(select_id))the issue is line # 4. "matches" is a dictionary that stores a well ID with a list of ID's of potential orps matches. I want line 4 to select all the orps that have U_ID's in a particular entry of the dictionary.
Like I said, when testing this on a smaller dataset, it worked perfectly fine. But now that I try it on a full town's worth of wells/orps, it fails, giving the following error code:
Traceback (most recent call last):
File "<pyshell#8>", line 1, in <module>
arcpy.SelectLayerByAttribute_management(orpsFL, "NEW_SELECTION", "U_ID = {}".format(select_id))
File "C:\Program Files (x86)\ArcGIS\Desktop10.2\arcpy\arcpy\management.py", line 6494, in SelectLayerByAttribute
raise e
ExecuteError: ERROR 000358: Invalid expression
Failed to execute (SelectLayerByAttribute).
What is suddenly making this expression invalid??
Thanks in advance,
Tom
