Hibernate Dialects

Hibernate Dialects

Dialect is a Java class available in org.hibernate.dialect package, which helps to map Java Application with the database. To interact with the database, we need to define the required database dialect in the hibernate.cfg.xml file. Hibernate uses dialect configuration to identify which database a user is using.

The org.hibernate.dialect package contains a bunch of dialect classes which are supported by the Hibernate framework with the latest functionalities of the databases.

Hibernate is database-independent as it provides ‘Database Dialect’ so we need not write SQL queries. The main aim of dialect is to translate HQL queries into native database format because HQL is a database-independent language. For example, if we are using the Oracle database, we need Oracle dialect to convert the HQL query into Oracle format. 

Syntax of Dialect

;org.hibernate.dialect.MySQLDialect

Let’s see how we use dialect in the configuration file.


http://www.hibernate.org/dtd/hibernate-configuration-5.3.dtd">


org.hibernate.dialect.Oracle9Dialect
jdbc:oracle:thin:@localhost:1521:xe
oracle.jdbc.driver.OracleDriver
root //write your username
root //write your password

In the above example, we have used the Oracle 9i dialect for the database connection.
