Q: What operations does the MySQL node support in n8n?

The node supports Execute Query (run any SQL statement), Insert (add new rows to a table), Update (modify existing rows matched by a key column), and Delete (remove rows). Execute Query gives you full control to run JOINs, aggregations, subqueries, and stored procedures. The other operations provide a simpler interface for common CRUD tasks.

Q: How does the MySQL node handle database security?

The node uses parameterised queries by default, which prevents SQL injection attacks. It supports SSL/TLS encrypted connections and SSH tunnel connections for databases that are not publicly accessible. Credentials (host, port, username, password) are stored encrypted in n8n's credential store, not in the workflow definition.

Q: Can I connect to a MySQL database behind a firewall?

Yes. The MySQL node supports SSH tunnel connections. You provide the SSH host, username, and key, and n8n creates a secure tunnel to reach your database. This is the standard setup for connecting to databases in private networks or cloud VPCs without exposing them to the public internet.

Q: What are common MySQL automation use cases in n8n?

Common setups include syncing orders from an e-commerce API into a MySQL reporting database, pulling customer data from MySQL to populate CRM records, running nightly queries to generate business reports, updating inventory levels based on incoming stock notifications, and archiving old records to keep production tables performant.

Q: Does the MySQL node work with MariaDB?

Yes. MariaDB is wire-compatible with MySQL, and the n8n MySQL node works with both. You use the same connection settings (host, port, username, password, database name) regardless of whether the server is running MySQL or MariaDB. Most queries and operations behave identically across both databases.

Q: Can Osher build MySQL-connected automations for our business?

Yes. Our n8n team builds MySQL-connected workflows regularly, from simple data lookups to complex multi-table sync pipelines. We write optimised SQL queries, configure secure connections (SSL and SSH tunnels), and set up proper error handling for database operations. See our patient data entry case study for an example of MySQL-driven automation.

We can help you automate your business with MySQL and hundreds of other systems to improve efficiency and productivity. Get in touch if you’d like to discuss implementing MySQL.

About MySQL

The MySQL node in n8n connects your workflows directly to MySQL and MariaDB databases, letting you read, write, update, and delete records as part of automated processes. It turns n8n into a bridge between your database and every other system in your stack.

Most business applications store their core data in a relational database. Customer records, orders, inventory, transactions. The MySQL node lets your automations query that data, write new records, update existing ones, and run custom SQL statements. This means your workflows can pull real-time data from production databases, sync records between systems, and trigger actions based on database changes.

The node supports parameterised queries to prevent SQL injection, SSL/TLS connections for encrypted communication, and SSH tunnelling for databases behind firewalls. You can run SELECT queries to fetch data, INSERT statements to add records, UPDATE statements to modify data, and raw SQL for complex joins or aggregations.

At Osher, MySQL integration is a core part of our data processing and system integration work. We connect MySQL databases to CRMs, reporting tools, API endpoints, and other databases as part of automated data pipelines. Our patient data entry automation project relied on MySQL for structured data storage and retrieval within the workflow. Our n8n team writes optimised queries and configures secure database connections for production use.

How it works

We work hand-in-hand with you to implement MySQL

As MySQL consultants we work with you hand in hand build more efficient and effective operations. Here’s how we will work with you to automate your business and integrate MySQL with integrate and automate 800+ tools.

Step 1

Process Audit

We review your MySQL database schema, identify which tables and data flows are relevant to your automation goals, and assess how data currently moves between your database and other systems. This includes documenting table structures, data volumes, query patterns, and security requirements.

Step 2

Identify Automation Opportunities

We identify which database operations can be automated within n8n workflows. Common targets include data synchronisation between MySQL and external APIs, automated report generation from database queries, record creation based on incoming webhook data, and data cleanup or archival jobs.

Step 3

Design Workflows

We design n8n workflows with MySQL nodes configured for each required database operation. Each query is specified with its exact SQL, parameters, and expected results. We define connection security settings (SSL, SSH tunnel), error handling for query failures, and transaction boundaries where data integrity requires it.

Step 4

Implementation

We configure MySQL credentials in n8n with the appropriate security settings, build the workflows, and test each database operation against your development or staging database. We verify that queries return the expected results, inserts write correctly, and error handling catches connection failures and query errors.

Step 5

Quality Assurance Review

We test database workflows against edge cases: empty result sets, duplicate key violations, connection timeouts, and large result sets. We verify that parameterised queries prevent injection, SSL connections are enforced, and the workflow handles database downtime gracefully with appropriate retries and notifications.

Step 6

Support and Maintenance

We monitor database workflows for slow queries, connection failures, and unexpected result counts. When your database schema changes (new columns, renamed tables, modified constraints), we update the SQL queries and field mappings in your n8n workflows to match.
