One of the great things about Hibernate is that it’s open-source and, therefore, free. Hibernate is the object-relational mapping (ORM) tool of choice for many developers using the Java ecosystem. Let’s explore them in detail, but first, their introduction. These are two awesome object-relational mapping tools, which both have their strengths and weaknesses. Select the one with the necessary JVM options or run with the default settings.Are interested in Hibernate vs JDBC and want to know which to use in your project? When you open the Hibernate console, IntelliJ IDEA will display an additional VM and Env Configuration popup with the available run configurations. The rest of the run configuration settings don't matter, and you don't need to specify them. In the VM options field, specify the options that you want to pass to the JVM when it starts. Go to Run | Edit Configurations, click, and select Application. If necessary, you can start it with custom JVM options: Run the Hibernate console with custom JVM options Place the caret at the name of the relevant object or property and press Control+B or select Navigate | Go to Declaration from the main menu. Hold Control and click the relevant object or property. When composing a query, it is useful to look at the declaration of the corresponding class or field. Navigate to the declaration of a class or field Press ArrowUp to see the previously executed commands, starting from the most recent one. IntelliJ IDEA stores all queries that you execute. Alternatively, click to open the Parameters pane. When you execute a query with parameters, you will need to enter their values. Restore the original tool window layout after layout changes.Īfter you write a query, do one of the following: Open the console history dialog that shows all the queries that you have run in this console. Open the Parameters pane to see the parameters used in your queries and set their values. Open the Database page of the Settings dialog Control+Alt+S. Generate an SQL statement or a DDL script.Ĭontrol+Shift+Enter Generate SQL: Generate an SQL equivalent of the current JPQL statement.Ĭontrol+Alt+Shift+Enter Generate DDL: Generate the corresponding CREATE TABLE, ALTER TABLE, and DROP TABLE statements for all the objects (classes) associated with the current persistence unit. ![]() The Hibernate console toolbar contains the following buttons: The Hibernate console input pane opens as a separate tab where you can write and execute HQL queries. Alternatively, you can click in the toolbar or press Control+Shift+F10. ![]() In the Persistence tool window, right-click a session factory or entity and select Console. If you are using custom entity class or database table name mappings that are not fully reflected in your code and configuration files, specify the corresponding NamingStrategy implementation, refer to Associate persistence units with naming strategies. For more information, refer to Associate persistence units with data sources. Otherwise, you will have to manually specify the database connection settings when using the JPA console. You project should use JDK 8 or later for the Hibernate console to be available.Īssociate your session factories with the corresponding data sources. It provides useful highlighting and completion for JPQL keywords, object and property names. Use the Hibernate console to write and run HQL queries.
