I know there's a way to do it in subsequent versions, but I'm dealing with 10.1. I need to make changes to definition queries to multiple layers (the field used in the query is the same throughout all layers). Is there a way to do it without having to go into each layer's properties? Thanks.
Was arcpy mapping module available then?
Because they can be changed in table properties
and there is a scripting example at the bottom of this link
