This method can only be used in the context of a user-defined default generation function, e.g. as described at :ref:`context_default_functions`. When invoked, a dictionary is returned which includes entries for each column/value pair that is part of the INSERT or UPDATE statement. The keys of the dictionary will be the key value of each :class:`_schema.Column`, which is usually synonymous with the name. :param isolate_multiinsert_groups=True: indicates that multi-valued INSERT constructs created using :meth:`_expression.Insert.values` should be handled by returning only the subset of parameters that are local to the current column default invocation. When ``False``, the raw parameters of the statement are returned including the naming convention used in the case of multi-valued INSERT. .. versionadded:: 1.2 added :meth:`.DefaultExecutionContext.get_current_parameters` which provides more functionality over the existing :attr:`.DefaultExecutionContext.current_parameters` attribute. .. seealso:: :attr:`.DefaultExecutionContext.current_parameters` :ref:`context_default_functions` sd get_current_parameters() can only be invoked in the context of a Python side column default functioni i c 3 s) | ] } | � d | � f f Vq d S( s %s_m%dN( ( R� R^ ( t indexR� ( sL /opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/engine/default.pys <genexpr>F s N( t current_parametersR t AttributeErrorR Ry RP t compile_stateRj t _has_multi_parameterst _is_multiparam_columnR R^ t originalt _dict_parameterst keysR� ( RF t isolate_multiinsert_groupsR R R� R ( ( R R� sL /opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/engine/default.pyt get_current_parameters s( ! c C s0 | j d k r d S| j | | j | j � Sd S( N( R R1 R RJ ( RF R ( ( sL /opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/engine/default.pyt get_insert_defaultL s c C s0 | j d k r d S| j | | j | j � Sd S( N( t onupdateR1 R RJ ( RF R ( ( sL /opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/engine/default.pyt get_update_defaultR s c C s� | j j } i } | j j } | j j } xC | D]; } | j r1 | j j r1 | j j r1 | j j | | <q1 q1 Wx6 | D]. } | j rw | j j rw | j j | | <qw qw Wx� | j D]� } | | _ xU | D]M } | | k r� | | } n | j | � } | d k r� | | | | � <q� q� WxU | D]M } | | k r@| | } n | j | � } | d k r!| | | | � <q!q!Wq� W| ` d S( N( RP t _within_exec_param_key_getterRw Rx R R t is_scalarRK R RW R R R1 R ( RF t key_gettert scalar_defaultsRw Rx t cR� t val( ( sL /opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/engine/default.pyRy X s2 " c C s� | j j } | j d | _ } xs | j j D]e } | j rd | j j rd | j j rd | j j } n | j | � } | d k r- | | | | � <q- q- WxB | j j D]4 } | j | � } | d k r� | | | | � <q� q� W| ` d S( Ni ( RP R RW R Rw R R R RK R R1 Rx R ( RF R RW R R!
