def from_statement(self, statement) 

Description

from_statement.__doc__

Execute the given SELECT statement and return results.

        This method bypasses all internal statement compilation, and the
        statement is executed without modification.

        The statement is typically either a :func:`_expression.text`
        or :func:`_expression.select` construct, and should return the set
        of columns
        appropriate to the entity class represented by this
        :class:`_query.Query`.
