Select clause

Functional

The select clause takes a list of nodes, and produces a list of nodes of type row.

Description

The select clause does not filter the set of nodes (rows), but filters the nodes on the second level: the columns. And allows many forms of projection to new nodes and nodes shapes.

Syntax

select-clause: 'select' (field-list | group)

A field-list is a list of field-declarations separated by a comma. See field declarations for more details.
