Final answer:
To add a criterion using a comparison operator for a Number field in a query's Design view, open the query, select the field, and enter the operator and value in the Criteria row. Use comparison operators such as >, <, >=, <=, <>, or BETWEEN to filter records.
Step-by-step explanation:
To add a criterion using a comparison operator for a Number field to a query in Design view, you would first open the query in Design view within your database application, such as Microsoft Access. Then, locate the Number field you want to apply the criterion to. In the Criteria row for that field, enter the comparison operator and the value you want to compare the field's data against.
For example, if you want to find all records where the Number field is greater than 100, you would type ">100" in the Criteria row. Other comparison operators include < (less than), <= (less than or equal to), >= (greater than or equal to), <> (not equal to), and BETWEEN for a range of values.
In a query in Design view, you can add a criterion using a comparison operator for a Number field. For example, if you have a Number field named 'Age' and you want to find all records where the age is greater than 18, you can add the criterion 'Age > 18'.
This criterion will only return records where the value in the 'Age' field is greater than 18. You can use other comparison operators like '<', '>', '<=', '>=', or '<>' to create different criteria based on your needs.
