If I have this file geodatabase table with the format of:
ColA | ColB| ColC | ColD | ColE | ColF etc...
I want to declare a combination of columns will be the primary key
(ColA | ColB| ColC). When I say primary key, I want to say that the combination of
ColA | ColB| ColC defines a unique row within the table.
I was thinking of using
Add Attribute Index tool in ArcGIS Desktop on these three columns, but I'm not sure if that is the right approach.
