sql - 单个记录中的数据

Question

下面是 sql 选择查询输出。

Col1            Col2    Col3    Col4        Col5    Col6    Col7    Col8    Col9
-------------------------------------------------------------------------------------
General-Surgery John    193850  21/06/2013  Smith   NULL    704.08  NULL    NULL
General-Surgery John    193850  21/06/2013  Smith   2510    NULL    NULL    NULL
General-Surgery John    193850  21/06/2013  Smith   NULL    NULL    NULL    19950
General-Surgery John    193850  21/06/2013  Smith   NULL    NULL    0       NULL

这里 Col1, Col2, Col3, Col4, Col5 重复.. 我只想要一条记录中的所有数据（删除 NULL）就像下面一样..

Col1            Col2    Col3    Col4        Col5    Col6      Col7     Col8    Col9
---------------------------------------------------------------------------------------
General-Surgery John    193850  21/06/2013  Smith   704.08    2510     19950   0

请在这方面帮助我

感谢期待。
