In this section, we will show you, how to use the Max() function. Hibernate supports multiple aggregate functions. When they are used in HQL queries, they return an aggregate value ( such as avg(...), sum(...), min(...), max(...) , count(*), count(...), count(distinct ...), count(all...) ) calculated from property values of all objects satisfying other query criteria.
Following is a aggregate function (max() function) with their respective syntax.
max( [ distinct | all ] object.property)
The Max() function aggregates the maximum value of the given column.
