access formula full
Answers
Explanation:
A formula is a way of expressing information symbolically, such as with mathematical or chemical symbols. It comes from the Latin forma, meaning “form,” as in shape or pattern. In Access, formulas can be used in calculated fields in tables and queries, in control sources on forms and reports, and elsewhere.
In Access, formulas are commonly referred to as expressions. This can get tricky at times because an expression can be either the whole or just a part. To simplify matters, we’ll use “formula” to represent the whole and reserve “expression” for referring to a part or element of the whole.
Formulas in Access can contain functions, operators, references (identifiers), and/or constants. They involve any number of expressions to calculate values, validate data, or even set a default value for a field or control.
