Install free

Visual Studio Marketplace · Open VSX

ext install nexosqlstudio.nexo-sql-studio

Connect and run SQL

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 in your engine’s first-query tutorial.
5. Inspect the results. Use a disposable database for write examples and review commit/rollback behavior before changing production data.

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.

Free covers core SQL workflows. Pro adds advanced development, delivery and AI/MCP tools. A Pro license does not make an unsupported engine feature available.

Advanced Oracle development

Keep the depth your Oracle projects need: service names and SIDs, Easy Connect, TNS, TCPS and wallets, alongside PL/SQL intelligence, debugging, utPLSQL and APEX/ORDS workflows. Advanced features have their own plan and compatibility requirements.

Ordinary Oracle connections use the bundled Thin driver and do not require Oracle Instant Client. Thick-mode or external-authentication workflows may require additional Oracle client configuration.
