I have a table of event_id, event_time. Many times, several events happen in a row. I'd like a query which replaces all of those events with a single record, showing the count.
Eg: Take A,A,A,B,C,A,D,A,A,D,D,B,C,C and return: A,3; B,1; C,1; A,1; D,1; A,2; D,2; B,1; C,2 How can I do that? -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
