Connect to JDBC
Learn how to connect a JDBC driver to Retool.
You can use the JDBC integration to create a resource and make it available in Retool. Once complete, your users can write queries that interact with JDBC data.
Requirements
The JDBC integration requirements depend on whether you have a cloud-hosted or self-hosted Retool organization. You may also need to make JDBC configuration changes before creating the resource.
- Cloud-hosted organizations
- Self-hosted organizations
Sufficient user permissions to create resources
All users for Retool organizations on Free or Team plans have global Edit permissions and can add, edit, and remove resources. If your organization manages user permissions for resources, you must be a member of a group with Edit all permissions.
Allow Retool to access the data source
If the data source is behind a firewall or restricts access based on IP address, then you must ensure that your Retool organization can access it. If necessary, configure your data source to allow access from Retool's IP addresses.
3.77.79.248/30
35.90.103.132/30
44.208.168.68/30
3.77.79.249
3.77.79.250
35.90.103.132
35.90.103.133
35.90.103.134
35.90.103.135
44.208.168.68
44.208.168.69
44.208.168.70
44.208.168.71
Retool is building support for querying firewalled resources without allowlisting Retool’s IP address. To learn more or be considered for early access, contact cloud-connect@retool.com.
JDBC settings and authentication
You must have sufficient access and familiarity with your JDBC data source so you can provide:
- Required connection settings (e.g., URL and server variables).
- Authentication credentials (e.g., API keys).
In some cases, you may need to make changes to your JDBC configuration, such as generating authentication credentials or allowing access through a firewall. Refer to the configuration and authentication sections to learn more.
Sufficient user permissions to create resources

Allow your deployment to access the data source
Your self-hosted deployment must have access to the data source. Ensure that any potential firewall rules for either the data source or your deployment instance are updated to allow them to communicate.

Configure the resource
Sign in to your Retool organization and navigate to the Resources tab. Click Create new > Resource, then select JDBC.
Configuration
Specify the name, location, and description to use for your JDBC resource. Retool displays the resource name and type in query editors to help users identify them.
Provide the following configuration settings to create the resource. Depending on how your data source is configured, you may also need to provide optional settings for Retool to connect.
- Cloud-hosted organizations
- Self-hosted organizations
Name
The name to use for the resource.
Description
A description of the resource.
Driver name
The JDBC driver to use.
Driver | Description |
---|---|
com.ibm.db2.jcc.DB2Driver | IBM DB2 |
com.clickhouse.jdbc.ClickHouseDriver | ClickHouse |
io.trino.jdbc.TrinoDriver | Trino |
com.ingres.jdbc.IngresDriver | Ingres |
com.teradata.jdbc.TeraDriver | Teradata |
com.informix.jdbc.IfxDriver | IBM Informix |
Connection string
The database connection string.
Disable converting queries to prepared statements
Whether to disable SQL injection protection that allows dynamically generated SQL using JavaScript.
Override default outbound Retool region
Retool connects to your data source from the us-west-2
region. Choosing a different outbound region can improve performance through geographic proximity.
Region | Location |
---|---|
us-west-2 | US West (Oregon) |
eu-central-1 | (Frankfurt, Germany) |
Name
The name to use for the resource.
Description
A description of the resource.
Driver name
The JDBC driver to use.
Connection string
The database connection string.
Schema query
The SQL query to retrieve the schema.
Disable converting queries to prepared statements
Whether to disable SQL injection protection that allows dynamically generated SQL using JavaScript.
Self-hosted organizations must also update the deployment configuration to use this resource. The following guidance is for Docker-based deployments. If you use Helm or Kubernetes, use the respective deployment guides for mounting instructions instead.
Update Retool
Run ./update_retool.sh
to update Retool.
Include JDBC dependencies
Create the /retool_backend/jdbc
directory and add the JDBC .jar
files to it. Include any .jar
dependencies that your files need.
Update Docker configuration
Update docker-compose.yml
to include the JDBC directory for the api
, db-connector
, and db-ssh-connector
containers.
./jdbc:/retool_backend/jdbc
Update docker.env
to include a path to the JDBC directory.
JDBC_DIRECTORY_PATH=/retool_backend/jdbc
Restart Retool
Run sudo docker-compose up -d
to restart Retool.
Test the connection
Click Test Connection to verify that Retool can successfully connect to the data source. If the test fails, check the resource settings and try again.
Testing a connection only checks whether Retool can successfully connect to the resource. It cannot check whether the provided credentials have sufficient privileges or can perform every supported action.
Save the resource
Click Create resource to complete the setup. You can then click either Create app to immediately start building a Retool app or Back to resources to return to the list of resources.
