    <p>This is a sample of the RAW DATA that I working with from the "employeeRatings" Table before the cfquery output:</p> <pre><code> (showcasing employeeID:1128 for the month of May) employeeID | Possible_Factor | Factor | ratingDate ======================================================================= 1128 | .1 | .1 | 5/25/2013 2:05:13 PM 1128 | .1 | .0 | 5/22/2013 9:30:43 AM 1128 | .2 | .1 | 5/17/2013 9:42:09 AM 1128 | .1 | .1 | 5/13/2013 8:07:15 AM 1128 | .1 | .0 | 5/10/2013 7:52:51 AM 1128 | .4 | .0 | 5/6/2013 12:41:12 PM </code></pre> <p>Here's the cfquery (SQL statement):</p> <pre><code>SELECT ROUND(100 * (SUM(Factor) / SUM(Possible_Factor)), 2) AS employeeRating, CONVERT(CHAR(4), ratingDate, 100) + CONVERT(CHAR(4), ratingDate, 120) AS month, employeeID, DATEADD(MONTH, DATEDIFF(MONTH, 0, ratingDate), 0) AS shortdate FROM employeeRatings GROUP BY CONVERT(CHAR(4), ratingDate, 100) + CONVERT(CHAR(4), ratingDate, 120), DATEADD(MONTH, DATEDIFF(MONTH, 0, ratingDate), 0), employeeID ORDER BY employeeID, DATEADD(MONTH, DATEDIFF(MONTH, 0, ratingDate), 0) DESC </code></pre> <p>After the cfquery, the output will look like this:</p> <pre><code>employeeID | employeeRating | month | shortdate ======================================================================= 1128 | 30 | May 2013 | 5/1/2013 12:00:00 AM 1128 | 60 | April 2013 | 4/1/2013 12:00:00 AM 1128 | 90 | Jan 2013 | 1/1/2013 12:00:00 AM 7310000 | 95 | April 2013 | 4/1/2013 12:00:00 AM 7310000 | 85 | Mar 2013 | 3/1/2013 12:00:00 AM 7310000 | 75 | Feb 2013 | 2/1/2013 12:00:00 AM 7310000 | 55 | Jan 2013 | 1/1/2013 12:00:00 AM 444981 | 27 | Mar 2013 | 3/1/2013 12:00:00 AM 444981 | 77 | Jan 2013 | 1/1/2013 12:00:00 AM 444981 | 97 | Nov 2012 | 11/1/2012 12:00:00 AM 444981 | 37 | Sept 2012 | 9/1/2012 12:00:00 AM 444981 | 47 | Aug 2012 | 8/1/2012 12:00:00 AM </code></pre> <p>I need to take an employee and list their LAST THREE ratings (if month is null, skip the null month and get the next month with a rating in order to showcase last three documented ratings). This is a dynamic cfquery that list over 200 employees. The following is the desired output:</p> <pre><code>supplierID | LastRating | SecondLastRating | ThirdLastRating ====================================================================== 1128 | 30 | 60 | 90 7310000 | 95 | 85 | 75 444981 | 27 | 77 | 97 </code></pre> <p>I am using ColdFusion on a SQL Server 2000 (compatibility 80), however the ColdFusion version I am using do not support cfloop group attribute. I would like to take the new output and put it into a new query, so it can be JOINED with another query. A solution = starbucks gift from FB ;) Thank you everyone for your time and consideration!!!!</p>

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.
