    <p>I need to compare all orders of type 728 to all of the other order types for each customer to find any customers where order types 728 have any items that are not in at least one other order type, or if any of the other order types have any items that are not in order type 728 for that customer.</p> <pre><code> Customers OrderTypes Items Customer 2245 OrderType 728 Item PT Item Custom Item Special OrderType 234 Item PT Item Custom OrderType 300 Item PT Item Custom OrderType 999 Item PT </code></pre> <p>I have queried so that I have a table variable of the order types of 728 (with Customer and order type data), @Items_728</p> <p>I have queried so that I have a table variable of the order types of everything but 728 (with Customer and order type data), @Items_Not728</p> <p>I want to get a resultset of all 728 order types per customer that have items not in other order types for that customer.</p> <p>Example: OrderType 728 has an Item Special not found in at least one other OrderType</p> <p>I want to get a resultset of all order types per customer that have items not in the 728 order type.</p> <p>Example: OrderType 999 does not have Item Custom</p> <p>I would like to do this as a set-based operation, rather than creating a cursor and walking it customer by customer, manually comparing sets of orders, noting any differences and saving each customer number. That seems terribly inefficient and dirty.</p> <p>I have looked through other StackOverflow questions but have not noted anything that seemed to look like this. Any helpful suggestions would be very much appreciated.</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.
