    1. COIs that your exact query or are you using parameterised queries? If it isn't your exact query please post the actual query and the table definition including indexes.

    2. COThis might seem like using a sledgehammer to crack a nut, but could you make your delete command into a stored procedure. Also, have you tried connecting via Native Client rather than SQLOLEDB? http://www.connectionstrings.com/sql-server/

    3. COHave edited to show exact query. How do I show table definition? Have right clicked on table and then properties, but not really sure what it is helpful for you to see there.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
