Sql server 修改我的查询以使用“最新”提取数据；logcreateddate"；

我正在使用Sql Server Management Studio 2012，我创建了一个Sql查询，可以在下面找到：

SELECT
    workorder.wonum as "WorkOrderNo",
    Workorder.description as "WorkorderDescription",
    Workorder.status as "WOstatus",
    Workorder.reportdate as "WOReportedDate",
    workorder.plusgmatrixprior as "WOPriority",
    wfassignment.startdate as "WorkflowStartDate",
    wfassignment.assigncode as "AssignedToLoginID",
    wfassignment.description as "AssignmentDescription",
    worklog.createby as "LogEnteredby",
    worklog.createdate as "LogCreatedDate",
    worklog.eventcode as "EventCode",
    worklog.logtype as "LogType",
    worklog.delayed as "ReasonforDelay",
    worklog.description as "LogDescription",
    worklog.description_long as "LoglongDescription"
FROM
    wfassignment, 
    workorder, 
    worklog
WHERE
    wfassignment.ownertable = 'workorder'
    AND wfassignment.ownerid = workorder.workorderid
    AND worklog.recordkey = workorder.wonum
    AND worklog.class = workorder.woclass
    AND workorder.siteid = 'adrd'
    AND wfassignment.assignstatus = 'active'
    AND wfassignment.assigncode = 'TRW4074'
    AND worklog.createby = 'TRW4074'
ORDER BY 
    workorder.wonum desc;

我已经运行了查询。输出表包含一些行，这些行与不同的

LogCreatedDate

具有相同的

WorkOrderNo

我想用最新或最大值

LogCreatedDate

获取上述查询中的所有字段

注意：我已尝试使用

max（）

函数和

分组依据

。但它并没有起作用，因为其他领域并不是独一无二的。因此，输出包含重复的

WorkOrderNo

---

请帮助修改上述查询或向我提供获取所有最新日期字段的建议。

使用

外部应用
：

    wo.description AS "WorkorderDescription",
    wo.status AS "WOstatus",
