[MonetDB-users] how to use DataCell
I would like to start experimenting with MonetDB/DataCell but am having trouble getting started. I read M. Kersten, E. Liarou, and R. Goncalves. A Query Language for a Data Refinery Cell. In EDA-PS, 2007. In section 2.1 of that paper it has the following syntax for creating a basket: create basket X( tag timestamp default now(), id serial, payload integer ); When I input this to mclient (Apr2012-SP2 version) I get: 42000!syntax error, unexpected IDENT, expecting INDEX in: "create basket" In the source code in the file sql/test/BugTracker-2011/Tests/UDF_in_schema.Bug-2817.sql begins with: create schema datacell; create table datacell.basket_X( id integer auto_increment, tag timestamp default now(), payload integer ); This obviously resembles the above but seems like it is creating a normal table rather than a basket. Has the syntax for creating a basket changed? Or should I load/enable the datacell extension in some way? thanks Greg
Dear Greg The Datacell code is still experimental and not yet released for external use. regards, Martin On 7/17/12 7:22 AM, Greg Aumann wrote:
