HSQLDB

Official documentation

• For full information about HSQLDB, refer to the official documentation.

Connect to an HSQLDB database

1. To connect to the database, create a data source that will store your connection details. You can do this using one of the following ways:

   • From the main menu, navigate to File | New | Data Source and select HSQLDB.

   • In the Database Explorer ( View | Tool Windows | Database Explorer) , click the New icon () in the toolbar. Navigate to Data Source and select HSQLDB.

   

2. In the General tab of Data Sources and Drivers dialog right pane, specify the driver and connection type.

   1. From the Driver list, select the JDBC driver for your connection.

      For HSQLDB, the supported drivers are HSQLDB (Local) and HSQLDB (Remote).

   2. From the Connection type list, select the connection type depending on the connection details that you have:

      Connection types for HSQLDB (Local)

      • Embedded: connect by using the path to the database folder.

      • In-memory: connect to a temporary database stored entirely in the main memory.

      • URL only: connect by using only the URL.

      Connection types for HSQLDB (Remote)

      • default: connect by using Host, Port, Database, and URL.

      • URL only: connect by using only the URL.

      For the URL only connection type, the JDBC URL that you enter is used as is.

      For the other connection types, the JDBC URL is broken down into connection details. You can either specify them separately and use the automatically generated URL, or you can enter the URL directly in the corresponding field.

   

3. Check if there is a Download missing driver files link at the bottom of the connection settings area. Click this link to download drivers that are required to interact with a database. For a direct download link, refer to the JetBrains JDBC drivers page.

   Location for the downloaded JDBC drivers is the DataGrip configuration directory.

   

   You can also use your drivers for the database instead of the provided ones. For more information about connecting to a database with your driver, refer to Add a user driver to an existing connection.

   If there is no Download missing driver files link, then you already have the required drivers.

4. Specify the database connection details. Alternatively, paste the JDBC URL in the URL field.

   Connection types and settings for HSQLDB (Local)

   1. Enter the path to the database file or folder in Path. Alternatively, click the Open icon () and navigate to it.

   2. From the Authentication list, select the authentication method that you want to use to authenticate the connection. The following options are available:

      • User & Password: by using your login and password.

      • No auth: authentication is not required.

   3. In User and Password fields, type your user credentials.

      To use no password, leave the Password field empty.

      To delete a once entered password, right-click the Password field and select Set Empty.

      

   4. In the Database field, type the database name to which you want to connect.

   5. To connect to a certain existing database, deselect the If Exists checkbox. If you do not want to create a new database upon connecting, leave the checkbox selected.

   6. In the URL field, DataGrip generates the JDBC URL automatically using the values of other connection settings.

      If you need to use a JDBC URL with certain additional settings, paste it in the URL field. The general URL to use is as follows:

      • Format: jdbc:hsqldb:file:<path_to_the_file_or_folder>/<database_name>;ifexists=true

      • Example: jdbc:hsqldb:file:/Users/JetBrains/db/myDatabase;ifexists=true

      For more information about the URL format, refer to the HSQLDB official documentation.

   

   1. From the Authentication list, select the authentication method that you want to use to authenticate the connection. The following options are available:

      • User & Password: by using your login and password.

      • No auth: authentication is not required.

   2. In User and Password fields, type your user credentials.

      To use no password, leave the Password field empty.

      To delete a once entered password, right-click the Password field and select Set Empty.

      

   3. In the Database field, type the database name to which you want to connect.

   4. In the URL field, DataGrip generates the JDBC URL automatically using the values of other connection settings.

      If you need to use a JDBC URL with certain additional settings, paste it in the URL field. The general URL to use is as follows:
