Fonction all_ - module sqlalchemy

Signature de la fonction all_

def all_(expr) 

Description

all_.__doc__

Produce an ALL expression.

        This may apply to an array type for some dialects (e.g. postgresql),
        or to a subquery for others (e.g. mysql).  e.g.::

            # postgresql '5 = ALL (somearray)'
            expr = 5 == all_(mytable.c.somearray)

            # mysql '5 = ALL (SELECT value FROM table)'
            expr = 5 == all_(select(table.c.value))

        The operator is more conveniently available from any
        :class:`_sql.ColumnElement` object that makes use of the
        :class:`_types.ARRAY` datatype::

            expr = mytable.c.somearray.all(5)

        .. seealso::

            :func:`_expression.any_`

            :meth:`_types.ARRAY.Comparator.all`
