Query Options Dialog Box
You can use the Query Options dialog box to specify the settings for a query. This topic describes the options in the dialog box.
Designer displays the Query Options dialog box when you navigate to Menu > Query > Current Query Options in the Query Editor dialog box.
Designer displays these options:
Auto Join Defaults
You can specify the criteria based on which to join the tables automatically in the query in this box.
- Join on Foreign Keys
Select to automatically join tables in a query through a reference from Table A to a primary key in Table B. For example, an order form in Table A shows information on purchases that are made by a customer with a primary key of CustomerID. The customer ID # refers to a record in Table B which lists a specific address, phone number, name, and so on for the customer. CustomerID in Table A is a foreign key because it links the customer's ordering information in Table A to the customer's information in Table B using the CustomerID field. - Join on Primary Keys with Same Names
Select to automatically join tables in a query through a field or a combination of fields that uniquely and specifically identifies a record. For example, OrderID may be the primary key in a table for Orders and also for Payments. - Join on Same Name
Select to automatically join tables in a query through a link between two columns of the same name in two different tables. This often creates many invalid joins such as Amount that appears in both tables.

Show Table Names
