jdbcDriverOOo is part of a Suite of LibreOffice and/or OpenOffice extensions allowing to offer you innovative services in these office suites.
This extension is the transcription in pure Java of the java.sql.* API to the com.sun.star.sdbc, com.sun.star.sdbcx and com.sun.star.sdb API of UNO.
It allows you to use the JDBC driver of your choice directly in Base.
It embeds the drivers for the following databases:
Thanks to drivers providing an integrated database engine such as: HsqlDB, H2, SQLite, Derby or Jaybird, it is possible in Base to very easily create and manage databases, as easily as creating Writer documents.
You will find the information needed to create a database with these drivers in the section: Connection URL
Being free software I encourage you:
In short, to participate in the development of this extension.
Because it is together that we can make Free Software smarter.
jdbcDriverOOo is a JDBC driver written in Java.
Its use requires the installation and configuration in LibreOffice of a Java JRE or JDK version 17 or later.
I recommend Adoptium as your Java installation source.
The minimum version of LibreOffice supported by the jdbcDriverOOo extension depends on how you installed LibreOffice on your computer:
Regardless of platform, if you installed LibreOffice from the LibreOffice download site, the minimum version of LibreOffice is 7.0.
On Linux, if you used the package manager to install LibreOffice, the minimum version of LibreOffice is 6.0. However, you must ensure that the system-provided Python version is not lower than 3.8.
In addition, you may experience the following issues:
sudo apt remove libreoffice-sdbc-hsqldb
(to uninstall the libreoffice-sdbc-hsqldb package)sudo apt remove libhsqldb1.8.0-java
(to uninstall the libhsqldb1.8.0-java package)If you still want to use the Embedded HsqlDB functionality provided by LibreOffice, then install the HyperSQLOOo extension.
pip install --upgrade <package-name>
For more information see: What has been done for version 1.1.0.
It seems important that the file was not renamed when it was downloaded.
If necessary, rename it before installing it.
Restart LibreOffice after installation.
Be careful, restarting LibreOffice may not be enough.
soffice
and using the key combination Ctrl + C
if after stopping LibreOffice, the terminal is not active (no command prompt).After restarting LibreOffice, you can ensure that the extension and its driver are correctly installed by checking that the io.github.prrvchr.jdbcDriverOOo.Driver
driver is listed in the Connection Pool, accessible via the menu: Tools -> Options -> LibreOffice Base -> Connections. It is not necessary to enable the connection pool.
If the driver is not listed, the reason for the driver failure can be found in the extension’s logging. This log is accessible via the menu: Tools -> Options -> LibreOffice Base -> Pure Java JDBC Driver -> Logging Options.
The Driver
logging must first be enabled and then LibreOffice restarted to get the error message in the log.
Remember to first update the version of the Java JRE or JDK installed on your computer, this new version of jdbcDriverOOo requires Java version 17 or later instead of Java 11 previously.
This explains how to use an HsqlDB database.
The protocols supported by HsqlDB are: hsql://, hsqls://, http://, https://, mem://, file:// and res://.
This mode of use explains how to connect with the file:// and hsql:// protocols.
In LibreOffice / OpenOffice go to menu: File -> New -> Database
In step: Select database
In step: Connection settings
file:///tmp/testdb;shutdown=true;hsqldb.default_table_type=cached;get_column_name=false
file:///c:/tmp/testdb;shutdown=true;hsqldb.default_table_type=cached;get_column_name=false
java -cp hsqldb.jar org.hsqldb.server.Server --database.0 file:///tmp/testdb --silent false
java -cp hsqldb.jar org.hsqldb.server.Server --database.0 file:///c:/tmp/testdb --silent false
hsql://localhost/
In step: Set up user authentication
If the connection was successful, you should see this dialog window:
Have fun…
If you want to update an embedded HsqlDB database (single odb file), please refer to the section: How to migrate an embedded database.
It is possible to update the JDBC driver (hsqldb.jar, h2.jar, derbytools.jar) to a newer version.
If you use HsqlDB as database, follow these steps:
SHUTDOWN COMPACT
or SHUTDOWN SCRIPT
.Now your database is up to date.
This driver allows in LibreOffice / OpenOffice Base the management of users, roles (groups) and their associated privileges of the underlying database.
User management of the underlying database is accessible in Base via the menu: Administration -> User administration
The privileges management of the users of the underlying database is accessible in this window by the button: Change privileges
If the privilege is inherited from an assigned role, the checkbox is a three-state type.
The management of the roles (groups) of the underlying database is accessible in Base via the menu: Administration -> Group administration
The management of users who are members of the group of the underlying database is accessible in this window via the button: Group users
The management of roles assigned to the group of the underlying database is accessible in this window via the button: Group roles
This functionality is an extension of the UNO API and will only be available if the underlying LibreOffice / OpenOffice driver allows it.
Certain databases such as HsqlDB, H2, SQLite Derby or Firebird via Jaybird allow the creation of the database during connection if this database does not yet exist.
This feature makes it as easy to create databases as Writer documents. Generally it is enough to add the option expected by the driver to the connection URL.
This connection URL may be different depending on the operating system of your computer (Windows, Linux or MacOS).
To create a database, in LibreOffice go to the menu: File -> New -> Database -> Connect to an existing database, then according to your choice:
file:///home/prrvchr/testdb/hsqldb/db;hsqldb.default_table_type=cached;create=true
C:\Utilisateurs\prrvc\testdb\hsqldb\db;hsqldb.default_table_type=cached;create=true
file:///home/prrvchr/testdb/h2/db
C:\Utilisateurs\prrvc\testdb\h2\db
file:///home/prrvchr/testdb/sqlite/test.db
C:/Utilisateurs/prrvc/testdb/sqlite/test.db
/home/prrvchr/testdb/derby;create=true
C:\Utilisateurs\prrvc\testdb\derby;create=true
embedded:/home/prrvchr/testdb/firebird?createDatabaseIfNotExist=true
embedded:C:\Utilisateurs\prrvc\testdb\firebird?createDatabaseIfNotExist=true
Normally, the extension is created with Eclipse for Java and LOEclipse. To work around Eclipse, I modified LOEclipse to allow the extension to be created with Apache Ant.
To create the jdbcDriverOOo extension with the help of Apache Ant, you need to:
source/jdbcDriverOOo/
build.properties
so that the office.install.dir
and sdk.dir
properties point to the folders where LibreOffice and its SDK were installed, respectively.ant

This driver was written to work around certain problems inherent in the UNO implementation of the JDBC driver built into LibreOffice / OpenOffice, namely:
In order to take advantage of the latest features offered by databases and among others HsqlDB, it was necessary to write a new driver.
Until version 0.0.3, this new driver is just a wrapper in Python around the UNO services provided by the defective LibreOffice / OpenOffice JDBC driver.
Since version 0.0.4, it has been completely rewritten in Java under Eclipse, because who better than Java can provide access to JDBC in the UNO API?
In order not to prevent the native JDBC driver from working, it loads when calling the following protocols:
xdbc:*
xdbc:hsqldb:*
xdbc:sqlite:*
xdbc:mariadb:*
xdbc:...
but uses the jdbc:*
protocol internally to connect.
It also provides functionality that the JDBC driver implemented in LibreOffice does not provide, namely:
