Hi, having a table similar to
| 1 | B | [2010-07-15 Do] | | 1 | B | [2010-07-16 Fr] | |---+---+-----------------| | 2 | C | [2010-07-17 Sa] | | 2 | C | [2010-07-18 So] | |---+---+-----------------| | 1 | B | [2010-07-19 Mo] | | 1 | B | [2010-07-20 Di] | | 1 | B | [2010-07-21 Mi] | | 1 | B | [2010-07-22 Do] | |---+---+-----------------| | 3 | D | [2010-07-23 Fr] | a simple group by gives me: | 6 | B | | 4 | C | | 3 | D | What I want to get is the values grouped by "subset", where a subset is a set of rows with identical column until the colum changes. Is there a way to get | 2 | B | | 4 | C | | 4 | B | | 3 | D | by SQL only? - Rainer -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
