从2个表中选择记录

Question

我在MySQL中有2个表，在这两个表中我有id，title，date和其他一些字段，一个表的名称是news，另一个表是gallery。

    Table news :
    id   |  title   |   date       |  ...
   ------+----------+--------------+-------
    1    | TestN 1  |  2012-12-12  | ...
    2    | TestN 2  |  2012-12-14  | ...
    3    | TestN 3  |  2012-12-14  | ...



     Table gallery :
    id   |  title   |   date       |  ...
   ------+----------+--------------+-------
    1    | TestG 1  |  2012-12-10  | ...
    2    | TestG 2  |  2012-12-12  | ...
    3    | TestG 3  |  2012-12-15  | ...

我想知道如何按日期顺序从两个表中选择ID，标题记录？有可能吗？

像这样：

   Result :
    id   |  title   |   date       |  ...
   ------+----------+--------------+-------
    1    | TestG 1  |  2012-12-10  | ...
    1    | TestN 1  |  2012-12-12  | ...
    2    | TestG 2  |  2012-12-12  | ...
    2    | TestN 2  |  2012-12-14  | ...
    3    | TestN 3  |  2012-12-14  | ...
    3    | TestG 3  |  2012-12-15  | ...
