How is Nexo SQL Studio different from a standalone database IDE?

Query, explore and develop with Oracle, PostgreSQL, MySQL, MariaDB, SQLite and Microsoft SQL Server in VS Code. Nexo SQL Studio combines a database client with dedicated Oracle SQL and PL/SQL tooling. 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.

Does Nexo have a built-in visual SQL Query Builder in VS Code?

Yes. Nexo SQL Studio Pro includes a visual Oracle Query Builder inside VS Code. You can drag and drop tables, select columns, define joins and filters, and open the generated SQL in an editable worksheet.

Do I need to leave VS Code to browse schemas or run Oracle SQL?

No. Connections, object browsing, worksheets, SQL and PL/SQL execution, results, object source editing, and cross-schema autocomplete are available from the Nexo SQL Studio extension.

Can I keep using Nexo with an AI client after closing VS Code?

Yes. The local Nexo MCP companion can keep approved database workflows available after VS Code closes. Sign in to Nexo Pro, allow MCP access for the connections you need, and install or enable the Nexo SQL Studio plugin in your AI client.

Can I try Nexo before buying Pro?

Yes. Start with the Free plan, and sign in to try the complete Pro feature set without a credit card before choosing a license.

SQL Developer lists PostgreSQL, MySQL and SQL Server connections through third-party JDBC drivers, mainly for migration workflows. MariaDB and SQLite are not listed in its supported third-party databases. Database connectivity does not imply the same development features.
