    <p>I have this simple piece of sql that does exactly what I need...</p> <pre><code>SELECT MIN(pb.Id) AS Id, MIN(pb.Quantity) AS Requested, SUM(pbi.Quantity) AS Total FROM PickBatchItems AS pb LEFT JOIN PickBatchItemLocations AS pbi ON pb.Id = pbi.PickBatchItemId GROUP BY pb.Id </code></pre> <p>Results in...</p> <pre><code>Id, Requested, Total 1 100 NULL 2 200 165 3 200 NULL </code></pre> <p>This is exactly what I want but I need this to be in Linq.</p> <p>So far I have...</p> <pre><code>var pick = (from pb in db.PickItems join pbi in db.PickItemLocations on pb.Id equals pbi.PickBatchItemId into TempJoin from resList in TempJoin.DefaultIfEmpty() where pb.Id == iPickItemId group resList by pb.Id into g select new { Id = g.Key, RequestedQuantity = g.Min(???????????????????????), SentQuantity = g.Sum(a =&gt; a.Quantity == null ? 0 : a.Quantity), }).FirstOrDefault(); </code></pre> <p>How can I get the <strong>RequestedQuantity</strong>?</p> <p><strong>UPDATE:</strong></p> <p>Thanks to 'David B' I have the answer:</p> <pre><code>var pick = (from pb in db.PickBatchItems join pbi in db.PickBatchItemLocations on pb.Id equals pbi.PickBatchItemId into TempJoin from resList in TempJoin.DefaultIfEmpty() where pb.Id == iPickItemId group new { PickItem = pb, PickItemLocation = resList } by pb.Id into g select new { Id = g.Key, RequestedQuantity = g.Min(a =&gt; a.PickItem.Quantity), SentQuantity = g.Sum(a =&gt; a.PickItemLocation.Quantity == null ? 0 : a.PickItemLocation.Quantity), }).FirstOrDefault(); </code></pre> <p>This joins and returns my two tables even if the PickBatchItemLocations table is empty.</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.
