单个记录中的数据

Question

下面是sql select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..我只想在单个记录中的所有数据(删除NULL)就像下面..

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

在这方面请帮助我

谢谢你的期待.
