Why connect MariaDB to DBeaver?

Connecting lets you run SQL, inspect schemas, and export data from a desktop IDE instead of the CLI. You gain autocomplete, ER diagrams, and result-set editing.

What prerequisites do I need?

Install DBeaver 23+ and ensure the MariaDB server is reachable, with a user that has SELECT privileges on your target database. Keep host, port, database, user, and password handy.

How do I add a MariaDB connection in DBeaver?

1) Click Database ▸ New Connection.2) Choose MariaDB (or MySQL if MariaDB is missing). 3) If prompted, allow DBeaver to download the MariaDB driver.

4) Fill the Host, Port (default 3306), Database, User, and Password. 5) Click Test Connection; resolve any driver or firewall issues. 6) Press Finish.

What is the correct JDBC URL syntax for MariaDB?

jdbc:mariadb URL structure

The URL follows:
jdbc:mariadb://<host>[:<port>]/<database>?user=<user>&password=<password>&useSSL=<true|false>

Optional parameters include serverTimezone, autoReconnect, and allowMultiQueries.DBeaver fills most fields but you can edit the URL in the Edit Driver Settings dialog.

How can I test the connection?

Click Test Connection. DBeaver displays driver load, handshake, and ping results. A green check means success.Otherwise, examine the error stack: authentication failures point to credentials; communication failures point to firewall, host, or port issues.

How do I run a first query on my ecommerce database?

Open the new connection, create an SQL Editor, and run:
SELECT c.name, o.order_date, o.total_amount FROM Customers c JOIN Orders o ON o.customer_id = c.id LIMIT 10;

DBeaver shows results in a grid where you can copy or export to CSV/JSON.

Best practices when working with MariaDB in DBeaver

• Use Projects to separate dev and prod connections.
• Enable Auto-commit off for safer DML.
• Store passwords in a secure keychain, not plaintext.

Common mistakes and how to avoid them

Wrong driver: Selecting MySQL driver can break SSL. Pick MariaDB or update the driver jar.
Invalid timezone: Omit serverTimezone or set it incorrectly, causing timestamp shifts. Specify the exact IANA timezone.

Frequently Asked Questions

Can I connect over SSH?

Yes. In the connection dialog, open Network, enable SSH, and enter bastion details.

Does DBeaver support SSL for MariaDB?

Absolutely.In SSL tab, add client key, client cert, and CA cert, or simply enable Require SSL.

Why How to Connect MariaDB to DBeaver is important

How to Connect MariaDB to DBeaver Example Usage


-- List latest orders with customer and item count
SELECT o.id,
       c.name AS customer_name,
       o.order_date,
       COUNT(oi.id) AS items
FROM Orders o
JOIN Customers c   ON c.id = o.customer_id
JOIN OrderItems oi ON oi.order_id = o.id
GROUP BY o.id, c.name, o.order_date
ORDER BY o.order_date DESC
LIMIT 20;

How to Connect MariaDB to DBeaver Syntax


jdbc:mariadb://host:port/database?user=username&password=secret
# Common options
useSSL=true|false           -- Enable TLS encryption
serverTimezone=UTC          -- Align server/client timezones
autoReconnect=true          -- Reconnect dropped sessions
allowMultiQueries=true      -- Run multiple statements in one call

Example filled URL for ecommerce DB:
jdbc:mariadb://db.prod.internal:3306/ecommerce?user=read_only&password=s3cur3&useSSL=true

Common Mistakes

Using the MySQL driver instead of MariaDB. This can cause SSL and JSON column incompatibilities. Fix by selecting the built-in <em>MariaDB</em> driver or adding the latest <code>mariadb-java-client</code> JAR.
Leaving <code>useSSL</code> off while the server enforces TLS. The handshake fails with "Packet received from server was incorrect". Set <code>useSSL=true</code> and provide certificates in the SSL tab.

Frequently Asked Questions (FAQs)

Can I save the connection parameters for my team?

Yes. Right-click the connection ▸ Edit ▸ General ▸ Export to create a .dbeaver file your teammates can import.

How do I switch between multiple MariaDB versions?

Create separate driver profiles in Driver Manager and assign them to each connection. DBeaver will load the proper client JAR per connection.

Is connection pooling available?

DBeaver uses one session per editor by default. Enable Keep-alive and set Maximum open connections in Driver Settings to mimic pooling and reduce logins.
