Synopsis
GREATEST(value,value, . . . )
Use this function to compare two or
more values and return the greatest value. In an
INTEGER datatype context, all values are treated
as integers for comparison. In a REAL datatype
context, all values are treated as REAL values for
comparison. If any parameter contains a case-sensitive string (i.e.,
with a BINARY flag), all values are compared as
case-sensitive strings.
