In Microsoft Office Access 2007, a formula is also known as an expression. An expression consists of a number of possible elements that you can use, alone or in combination, to produce a result, including:
- Identifiers (the names of fields, controls, or properties)
- Operators, such as + (plus) or - (minus)
You can use an expression (a formula) to:
- Perform a calculation.
- Retrieve the value in a field or control.
- Supply criteria to a query.
- Define data validation rules.
- Create calculated controls and calculated fields.
- Define group levels for reports.
