Entering Multiple Criteria with the OR Operator
After you've displayed the query for which you want to enter criteria in Design view, click the cell in the Criteria row for the field you want to match, and type your first criterion (here, IN).
Click in the or row in the same column, and type the second value you want to match (in this case, KY).
Click the Save button on the Standard toolbar in the main Access window to save the query design.
Click the Run button to run the query.
There may be times when you want to match more than one criteria. For instance, you might want to list all clients who live in Indiana, as well as those clients who live in Kentucky, as outlined here. To do so, you use the OR operator.
Access will automatically add quotation marks around your entry. You'll see these if you move to another field or open the query.
Access runs the query and displays a table containing only those records that match the criteria you entered (in this case, clients in Indiana or Kentucky).
Click the Close button to close the query window.
This type of query is sometimes called an OR query because the data in the selected table can match either the first criteria or the second criteria to be included in the results.
