Signature de la fonction select

def select(*args, **kw) 

Description

select.__doc__

Create a :class:`.Select` using either the 1.x or 2.0 constructor
        style.

        For the legacy calling style, see :meth:`.Select.create_legacy_select`.
        If the first argument passed is a Python sequence or if keyword
        arguments are present, this style is used.

        .. versionadded:: 2.0 - the :func:`_future.select` construct is
           the same construct as the one returned by
           :func:`_expression.select`, except that the function only
           accepts the "columns clause" entities up front; the rest of the
           state of the SELECT should be built up using generative methods.

        Similar functionality is also available via the
        :meth:`_expression.FromClause.select` method on any
        :class:`_expression.FromClause`.

            :ref:`coretutorial_selecting` - Core Tutorial description of
            :func:`_expression.select`.

        :param \*entities:
          Entities to SELECT from.  For Core usage, this is typically a series
          of :class:`_expression.ColumnElement` and / or
          :class:`_expression.FromClause`
          objects which will form the columns clause of the resulting
          statement.   For those objects that are instances of
          :class:`_expression.FromClause` (typically :class:`_schema.Table`
          or :class:`_expression.Alias`
          objects), the :attr:`_expression.FromClause.c`
          collection is extracted
          to form a collection of :class:`_expression.ColumnElement` objects.

          This parameter will also accept :class:`_expression.TextClause`
          constructs as given, as well as ORM-mapped classes.
