    <p>On the basis of what is seen, a generic SQL query like this would "flatten" those rows into a single row (but the 2 PgsCompleted values need different column names).</p> <pre><code> select AutoArtId , empArtStage , MIN(ArtStageCurrStat) as ArtStageCurrStat , MIN(PgsCompleted) as PgsCompleted1 , MAX(PgsCompleted) as PgsCompleted2 from YourTable group by AutoArtId, empArtStage </code></pre> <p>Some questions emerge aboout more or less than 2 rows, this may help:</p> <pre><code> select AutoArtId , empArtStage , MIN(ArtStageCurrStat) as ArtStageCurrStat , MIN(PgsCompleted) as PgsCompleted1 , MAX(PgsCompleted) as PgsCompleted2 , count(*) as num_of from YourTable group by AutoArtId, empArtStage having count(*) &lt;&gt; 2 </code></pre> <p>Here is an approach that uses row_number() which is available in SQL 2008. It assumes you have some field(s) in the table that will allow distinction of oldest and newest (here I have used an autonumbered ID) - AND the assumption that it is the oldest and newest that are the relevant record pairs. In <strong><a href="http://sqlfiddle.com/#!3/0a1ef/1" rel="nofollow">this sqlfiddle</a></strong> I dummied up some sample data representing one group of 3 records and another of a single record.</p> <pre><code>SELECT AutoArtId , empArtStage , MIN(ArtStageCurrStat) AS ArtStageCurrStat , MIN(PgsCompleted) AS PgsCompleted1 , MAX(PgsCompleted) AS PgsCompleted2 FROM ( SELECT AutoArtId , empArtStage , ArtStageCurrStat , PgsCompleted , row_number() over (partition BY AutoArtId, empArtStage ORDER BY ID ASC) AS oldest , row_number() over (partition BY AutoArtId, empArtStage ORDER BY ID DESC) AS newest FROM YourTable ) AS derived WHERE oldest = 1 OR newest = 1 GROUP BY AutoArtId , empArtStage </code></pre>

    3. CO@kark, it would be very helpful if you specified the dbms type and version - for example lead/lag may be useful or row_number() but without knowing what your dbms supports we are rather limited in possibilites

Querying!

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.
