Access: Max Function

In Access, the Max function returns the maximum of a set of values in a select query.

The syntax for the Max function is:

Max ( expression )

The expression argument represents a string expression identifying the field that contains the data you want to evaluate or an expression that performs a calculation using the data in that field. Operands in expression can include the name of a table field, a constant, or a function (not one of the other SQL aggregate functions). You can use Max to determine the largest values in a field based on the specified aggregation, or grouping.

SQL query

In Access, you can use the Max function in the query design grid, in an SQL statement in SQL view of the Query window, or in an SQL statement within Visual Basic code. It is used in conjunction with the Group By clause.
