In this version, we not only implement the more natural object hierarchies B, but also nest the results as a similar set of hierarchical object structures C. Again, we let the database do what it s best at and only return the necessary portions of the underlying objects. There are times where we will want to query otherwise unrelated items. In those cases, joining data is still required. Both options are available as the business needs demand. Regardless of which method works best for each situation, LINQ to SQL attempts to return just the values requested and only return them when needed. Usually, this is advantageous. Occasionally the lazy loading behavior results in more frequent interaction with the database than originally intended. Let s continue our exploration of LINQ to SQL by looking at times where the default behavior may result in more frequent database inquiries.

The code uses a special UNION parameter query, qryCheckRelateContact, that attempts to fetch related rows from tblCompanyContacts, tblCompanies (the ReferredBy field), tblContactEvents, and tblContactProducts, and returns the name(s) of the table(s) that have any related rows. When the code finds rows returned by the query, it formats a message containing names more meaningful to the user, and it includes all the tables that the user must clear to be able to delete the contact. The standard Access error message lists only the first related table that Access finds. Even when the check for related records finds no problems, the code also gives the user a chance to decide not to delete the contact after all.

The Many Faces of Microsoft Access Figure 2-15 shows a complex form that brings together data from three tables and loads the related employee picture from a file on your hard drive and displays it in a way that s easy to use and understand. This form includes all the fields from the tblEmployees table. You can tab or use the arrow keys to move through the fields. You can click the Personal Info tab to see additional information about the current employee. You can experiment with the Filter By Form and Filter By Selection toolbar buttons to see how easy it is to select only the records you want to see. For example, you can click in the Department field on the Company Info tab and then click the Filter By Selection button to display records only for the current department.

Note The frmEmployeesPlain form is the only form in the Housing Reservations database that you can open to see a built-in Form view menu bar and toolbar. All the other forms in the Housing Reservations sample database have form properties set to use a custom menu bar and toolbar. There are four other ways to look at a form: in Datasheet view, PivotTable view, PivotChart view, and Print Preview. You can select Datasheet View from the View button drop-down list to see all the fields in the form arranged in a datasheet similar to a datasheet for a table or a query. When a form has been designed to display data in a PivotTable (similar to a spreadsheet) or graphed in a PivotChart, you can select these views from the View button dropdown list. You can click the Print Preview button on the toolbar to see what the form will
