Thank you. I've been trying all sorts of queries, but notice the avg function becoming unavailable the moment I try a windowing operation? ________________________________ From: users-list [users-list-bounces+ocschwar=mit.edu@monetdb.org] on behalf of Corbit, Dann [Dann.Corbit@softwareag.com] Sent: Friday, October 20, 2017 5:07 PM To: Communication channel for MonetDB users Subject: RE: Proper syntax for a windowing function https://www.monetdb.org/Documentation/Manuals/SQLreference/WindowFunctions From: users-list [mailto:users-list-bounces+dann.corbit=softwareag.com@monetdb.org] On Behalf Of Omri Schwarz Sent: Friday, October 20, 2017 1:46 PM To: users-list@monetdb.org Subject: Proper syntax for a windowing function Hi, all. I'm trying to figure out the proper syntax for queries such as a moving average over a window in MonetDB. THis works: sql>select avg(energy) from TABLENAME; +--------------------------+ | L3 | +==========================+ | 658.5049567388747 | +--------------------------+ This fails: select avg(energy) OVER () from TABLENAME; SELECT: function 'avg' not found (Welcome to mclient, the MonetDB/SQL interactive terminal (Jul2017-SP1) Database: MonetDB v11.27.5 (Jul2017-SP1), 'mapi:monetdb://SERVER2:50000/scada' ) How do I write such a query? Many thanks.
