What is the difference between createQuery and createSQLQuery in hibernate?

createSQLQuery — is for native sql querying which is selected by you with jdbc driver cfg or something else. createQuery — is for hibernate querying which provides you independent querying which makes you run that on many databases using API and more other advantages.

What is createQuery in hibernate?

CreateQuery: Used to create an HQL. createNamedQuery: Used to define queries with name in mapping file or annotation. See this. createNativeQuery: Used to execute native/pure SQL queries. Example.

What is createSQLQuery?

After you pass a string containing the SQL query to the createSQLQuery() method, you can associate the SQL result with either an existing Hibernate entity, a join, or a scalar result using addEntity(), addJoin(), and addScalar() methods respectively.

What are the query types used in hibernate?

Hibernate Query Language (HQL) is an object-oriented query language, similar to SQL, but instead of operating on tables and columns, HQL works with persistent objects and their properties. HQL queries are translated by Hibernate into conventional SQL queries, which in turns perform action on database.

What is Hibernate Format_sql?

Hibernate has build-in a function to enable the logging of all the generated SQL statements to the console. You can enable it by add a “show_sql” property in the Hibernate configuration file “ hibernate. cfg. xml “. This function is good for basic troubleshooting, and to see what’s Hibernate is doing behind.

What is difference between HQL and Criteria in Hibernate?

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

Which is faster HQL or SQL?

Native SQL is not necessarily faster than HQL. HQL finally also is translated into SQL (you can see the generated statement when running the application with the show_sql property set to true).

Why is SQL better than HQL?

Unlike SQL, HQL uses classes and properties in lieu of tables and columns. HQL supports polymorphism as well as associations, which in turn allows developers to write queries using less code as compared to SQL.
