MariaDB: Run your first query

Connections, SQL worksheets and query results

1. Install Nexo SQL Studio and open Connections Explorer.
2. Add a connection, select the database engine and enter a unique name.
3. Enter the engine-specific fields. Test the connection, resolve any inline errors, then save.
4. Open a SQL worksheet from the saved connection and run the example below.
5. Inspect the results. Use a disposable database for write examples and review commit/rollback behavior before changing production data.

SELECT DATABASE(), VERSION();

SHOW TABLES;

Before connecting

Choose the actual engine: MySQL and MariaDB have separate adapters. Enter the database name, user and TLS settings; SQL syntax, server versions and authentication plugins can differ.

Troubleshooting

Check the selected engine, host or file path, database name, account permissions and TLS requirements. Keep the connection editor open while correcting failed tests. Include the engine, server version, extension version and a sanitized error when requesting support; never include passwords or wallet secrets.

• Feature availability

Database support does not imply identical features. Connections and SQL worksheets are the starting point; editing, DDL, modeling, transfers, administration and AI operations depend on the engine and workflow. Check the installed version and the relevant guide before relying on an advanced operation.
