Frequently Asked Questions
Everything you need to know about Nexo SQL Studio for Oracle development in VS Code.
Nexo SQL Studio is a Visual Studio Code extension for Oracle SQL and PL/SQL development. Free covers connections, object browsing, online cross-schema autocomplete, worksheets, snippets, object editing, standard result grids, and direct editing of supported simple query results; one Pro license adds offline intelligence, validation, deployments, AI/MCP, debugging, data modeling, and advanced database workflows.
Yes. Free is available without login. Sign in only when you want to activate and validate the single all-inclusive Pro license.
Nexo SQL Studio is designed for modern Oracle Database workflows, including Oracle 19c, 21c, 23ai, and the newer 26ai naming used by Oracle. We recommend validating critical workflows against your own database version and drivers.
Nexo SQL Studio follows industry-standard security practices and takes advantage of VS Code security measures plus the native encryption systems provided by each operating system. Keep your machine, VS Code, and Oracle client tooling updated for the strongest protection.
No SQL text, database credentials, schema/object names, file paths, result contents, or arbitrary user text are sent through usage telemetry. Free usage metrics are limited to allowlisted feature events such as feature attempts or upgrade-dialog views. Connections are made between your machine and the Oracle systems you configure.
AI, MCP, the companion, SQL optimization, agent workflows, and data-modeling assistance are Pro features. When activated, they can help search database context, execute queries you approve, compile objects, inspect errors, and create data models for Oracle workflows.
Statements are executed only when you trigger a workflow or approve an AI-agent action. Some features read Oracle metadata to power navigation, completions, and object browsing.
You can always open and edit local SQL/PLSQL files and use snippets. Nexo offline autocomplete, object/project generation, synchronization, validation, and deployment workflows require Pro, even when the files were downloaded by another tool.
Yes. Nexo SQL Studio runs anywhere VS Code runs. Oracle connection capabilities depend on the Oracle client libraries and drivers installed on your machine.
