Difference between HQL and Criteria Query

HQL is to perform both select and non-select operations on the data, but Criteria is only for selecting the data, we cannot perform non-select operations using criteria

HQL is suitable for executing Static Queries, where as Criteria is suitable for

executing Dynamic Queries

HQL doesn’t support pagination concept, but we can achieve pagination with Criteria

Criteria used to take more time to execute then HQL

With Criteria we are safe with SQL Injection because of its dynamic query generation but in HQL as your queries are either fixed or parameterized, there is no safe from SQL

Injection.
