Hello all, I am trying to do the following query but I would like to know how many rows were deduplicated in the process:
psql -d foo -c 'SELECT DISTINCT ON (error) error,ev_text FROM clients_event_log' -o fullfoo For example, I would want the output to be the following where count is the number of error rows that were deduplicated. count | error | ev_text 55 | 525152 | Some text 72 | 125124 | Some other text I imagine it's using the count function somewhere, just not sure how to embed that. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
