我有这个关联数组3-d
type v_arr_class is table of varchar2(255) index by varchar2(255);
type v_arr_component is table of v_arr_class index by varchar2(255);
type v_arr_property is table of v_arr_component index by varchar2(255);
v_arr_local_rec v_arr_property;

我需要验证索引是否存在
if(v_arr_local_rec('class')('component')('property') exist) then
do this...
end if

没有太多关于找到的关联数组的信息.
