Hi, I have a table 'tmvt' with a field 'created' in the row, and would like to compute the difference between successive rows. The solution I found is: It is complicate and very long to perform. The problem could be simply solved with MySql by creating a new field and updating it using a statement with @. I beleive this is a common problem for users. Do you know a simpler solution with postgreSql? -- View this message in context: http://postgresql.1045698.n5.nabble.com/obtain-the-difference-between-successive-rows-tp5729149.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
