TSQL分组/选择帮助

大家好，我想知道是否有人能伸出援手；下面显示了这个tsql脚本，如果记录处于活动状态并且记录创建日期小于今天的日期，它当前将根据所有者id返回数据。然后我将数据分组在一起。我想要实现的是返回每个公司的最新记录

目前我返回的数据如下：

COMPANY A   JOE BLOGS   NULL    10088   Green   NULL    NULL    21/07/2007 16:57 Phone Call
COMPANY B   JOE BLOGS   NULL    10059   Green   NULL    NULL    20/07/2007 14:57 Phone Call
COMPANY B   JOE BLOGS   NULL    10059   Green   NULL    NULL    18/07/2006 09:47    E-mail
COMPANY B   JOE BLOGS   NULL    10059   Green   NULL    NULL    19/07/2006 13:19    E-mail
COMAPANY C  JOE BLOGS   NULL    10866   Green   NULL    NULL    17/08/2007 12:57 Phone Call
COMAPANY C  JOE BLOGS   NULL    10866   Green   NULL    NULL    13/08/2007 10:59    E-mail
COMAPANY C  JOE BLOGS   NULL    10866   Green   NULL    NULL    15/08/2007 14:57    E-mail

这是我希望数据返回的方式：

COMPANY A   JOE BLOGS   NULL    10088   Green   NULL    NULL    21/07/2007 16:57 Phone Call
COMPANY B   JOE BLOGS   NULL    10059   Green   NULL    NULL    20/07/2007 14:57 Phone Call
COMAPANY C  JOE BLOGS   NULL    10866   Green   NULL    NULL    17/08/2007 12:57 Phone Call

谁能给我指一下正确的方向吗

SELECT fa.name, fa.owneridname, fa.new_technicalaccountmanageridname, fa.new_customerid, fa.new_riskstatusname, 
fa.new_numberofopencases, fa.new_numberofurgentopencases, fap.actualend, fap.activitytypecodename, fap.createdby, fap.createdbyname
FROM FilteredAccount fa
INNER JOIN FilteredActivityPointer fap ON fa.accountid = fap.regardingobjectid
WHERE fa.statecodename = 'Active' 
    AND fap.ownerid = '0F995BDC'
    AND fap.createdon < getdate()

GROUP BY fa.name, fa.owneridname, fa.new_technicalaccountmanageridname, fa.new_customerid, fa.new_riskstatusname, 
fa.new_numberofopencases, fa.new_numberofurgentopencases, fap.actualend, fap.activitytypecodename, fap.createdby, fap.createdbyname

试试这个

SELECT * FROM (
SELECT fa.name, fa.owneridname, fa.new_technicalaccountmanageridname, fa.new_customerid, fa.new_riskstatusname,  
fa.new_numberofopencases, fa.new_numberofurgentopencases, fap.actualend, fap.activitytypecodename, fap.createdby, fap.createdbyname ,
RN = ROW_NUMBER() OVER (PARTITION BY fa.name ORDER BY fap.createdby DESC)
FROM FilteredAccount fa 
INNER JOIN FilteredActivityPointer fap ON fa.accountid = fap.regardingobjectid 
WHERE fa.statecodename = 'Active'  
    AND fap.ownerid = '0F995BDC' 
    AND fap.createdon < getdate() 
) a WHERE RN = 1

这正是我想要的。但是，当我试图运行该命令时，在关键字“WHERE”附近出现了错误的语法。我已经看过了，对我来说很好看。另外，我还可以运行内部select fine并返回行号！找出问题所在，以备将来参考。需要声明一个表，我们从中选择外部选择！为帮助和剧本干杯：
