Program dups is not a built-in program in Stata, but can be installed over the internet using search dups (see How can I used the search command to search for programs and get additional help? for more information about using search) . Use TRIM in the select and GROUP BY clauses: SELECT COUNT(*) AS nb_duplicates, our_ref, TRIM(BOTH '\n' FROM partner_ref), partner_tag FROM partners_entries GROUP BY our_ref, TRIM(BOTH '\n' FROM partner_ref), partner_tag HAVING COUNT(*) > 1 Use an extended TRIM syntax to remove the newlines and other symbols from your data SQL Fiddle This video demonstrates how to identify and remove duplicate observations.
