GREATEST

Returns the greatest value from a list of input values. Use this function to return the greatest string, date, or number. By default, the match is case sensitive.

Syntax

GREATEST( value1, [value2, ..., valueN,] CaseFlag )

Argument	Required/ Optional	Description
value	Required	Any datatype except Binary. Datatype must be compatible with other values. Value you want to compare against other values. You must enter at least one value argument. If the value is numeric, and other input values are numeric, all values use the highest precision possible. For example, if some values are Integer datatype and others are Double datatype, Data Integration converts the values to Double.
CaseFlag	Optional	Must be an integer. Determines whether the arguments in this function are case sensitive. You can enter any valid expression. When CaseFlag is a number other than 0, the function is case sensitive. When CaseFlag is a null value or 0, the function is not case sensitive.

Return Value

value1 if it is the greatest of the input values, value2 if it is the greatest of the input values, and so on.

NULL if all the arguments are null.
