    <p>Wonder if someone could give me a quick hand. I have 2 select queries (as shown below) and I want to compare the results of both and only return the result that has the most recent date.</p> <p>So say I have the following 2 results from the queries:-</p> <pre><code>--------- ---------- ----------------------- --------------- ------ -- COMPANY A EMPLOYEE A 2007-10-16 17:10:21.000 E-mail 6D29D6D5 SYSTEM 1 COMPANY A EMPLOYEE A 2007-10-15 17:10:21.000 E-mail 6D29D6D5 SYSTEM 1 </code></pre> <p>I only want to return the result with the latest date (so the first one). I thought about putting the results into a temporary table and then querying that but just wondering if there's a simpler, more efficient way?</p> <pre><code>SELECT * FROM ( SELECT fc.accountidname, fc.owneridname, fap.actualend, fap.activitytypecodename, fap.createdby, fap.createdbyname, ROW_NUMBER() OVER (PARTITION BY fc.accountidname ORDER BY fap.actualend DESC) AS RN FROM FilteredContact fc INNER JOIN FilteredActivityPointer fap ON fc.parentcustomerid = fap.regardingobjectid WHERE fc.statecodename = 'Active' AND fap.ownerid = '0F995BDC' AND fap.createdon &lt; getdate() ) tmp WHERE RN = 1 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, ROW_NUMBER() OVER (PARTITION BY fa.name ORDER BY fap.actualend DESC) AS RN FROM FilteredAccount fa INNER JOIN FilteredActivityPointer fap ON fa.accountid = fap.regardingobjectid WHERE fa.statecodename = 'Active' AND fap.ownerid = '0F995BDC' AND fap.createdon &lt; getdate() ) tmp2 WHERE RN = 1 </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
