Use the MAX aggregate function to compute the maximum value in the column or column expression, specified by value_expression. MAX is valid for character data as well as numeric data. For a character expression, MAX returns the highest sort order.

Each aggregate join index must be created with a COUNT(*) or COUNT(value_expression). If you do not specify such an expression, Teradata Database adds a COUNT(*) by default.

You cannot specify a MIN function in the definition of a column-partitioned join index.

For more information about the MAX aggregate function, see Teradata Vantage™ SQL Functions, Expressions, and Predicates, B035-1145.
