Certain column names cause query syntax errors in SAS Enterprise Guide.
The problem will most likely occur when two or more column names are
very similar. For example, column names 'my var'n and 'my var name'n
will cause a message similar to the following when the columns are added
to the query or filter:

   Error: Column '''my var''n name'n could not be found in the
          table/view identified with the correlation name table_name.

To circumvent the problem, use column names that are more unique.
