    <p>First off, I am working in Access 2007.</p> <p>I have two queries that both aggregates by date.</p> <p>The first one returns an aggregated daily weighted return</p> <pre><code>SELECT Records.RecDate, Sum([YTD]*[Weight]) AS UnadjReturn FROM Records WHERE (((Records.[Class1])="eq") AND ((Records.[Class2])="ce")) GROUP BY Records.RecDate; </code></pre> <p>Result:</p> <pre><code>RecDate UnadjReturn 11/27/2012 0.060778036742704 12/11/2012 0.075592752895318 12/14/2012 7.47574641136453E-02 </code></pre> <p>I also have another query that returns daily total class portfolio weight by summing the weight of all the assets in an asset class with respect to the entire portfolio:</p> <pre><code>SELECT Records.RecDate, Sum(Records.Weight) AS SumOfWeight FROM Records WHERE (((Records.[Class1])="eq") AND ((Records.[Class2])="ce")) GROUP BY Records.RecDate; </code></pre> <p>which returns:</p> <pre><code>RecDate SumOfWeight 11/27/2012 0.479327081236988 12/11/2012 0.483075813390315 12/14/2012 0.482791727874428 </code></pre> <p>Now I would like to write a consolidated query that multiplies each day's <code>UnadjReturn</code> by <code>SumOfWeight</code>. I have tried <code>INNER JOIN</code> the two and then multiply the two variables as follows,</p> <pre><code>SELECT joined.RecDate, joined.UnadjReturn * joined.SumOfWeight as AdjReturn FROM joined ( SELECT Records.RecDate, Sum([YTD]*[Weight]) AS UnadjReturn FROM Records WHERE (((Records.[Class1])="eq") AND ((Records.[Class2])="ce")) GROUP BY Records.RecDate INNER JOIN ( SELECT Records.RecDate, Sum(Records.Weight) AS SumOfWeight FROM Records WHERE (((Records.[Class1])="eq") AND ((Records.[Class2])="ce")) GROUP BY Records.RecDate; ) t2 ON Records.RecDate = t2.RecDate AS joined ) </code></pre> <p>This is not looking good at all. Any suggestions? I could do it by querying the two queries with another query, but I would like to take care of it in just one. </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.
