- 4. Create and use a delete query The steps in this section explain how to create and use a delete query to delete entire records from a table: 1: On the Create tab, in the Queries group, click Query Design. The Show Table dialog box appears 1: Double-click each table from which you want to delete records, and then click Close. The table appears as a window in the upper section of the query design grid. The window lists all of the fields in the selected table. 1: Double-click the asterisk (*) to add all of the fields in the table to the design grid. Optionally, double-click any field that you want to use to specify criteria for deletion, enter one or more criteria in theCriteria row of the designer, and then clear the Show check box for each criteria field.
- 5. EXAMPLE For example, suppose that a customer goes out of business and you need to remove all of the pending orders for that customer. To find just those records, you add the Customer ID and Order Date fields to the design grid, and then you enter the ID number of the customer that went out of business, and the date on which that customer's orders became invalid.
- 6. IMPORTANT Use criteria to return only the records that you want to delete. Otherwise, the delete query removes every record in the table. On the Design tab, in the Results group, click View, and then click the Datasheet View. Verify that the query returns the records that you want to delete, and then press CTRL+S to save the query. To run the query, double-click the query in the Navigation Pane.
