Selectables, Tables, FROM objects¶
The term “selectable” refers to any object that rows can be selected from;
in SQLAlchemy, these objects descend from FromClause
and their
distinguishing feature is their FromClause.c
attribute, which is
a namespace of all the columns contained within the FROM clause (these
elements are themselves ColumnElement
subclasses).
Selectable Foundational Constructors¶

Selectable Modifier Constructors¶
Functions listed here are more commonly available as methods from
FromClause
and Selectable
elements, for example,
the alias()
function is usually invoked via the
FromClause.alias()
method.
