OQL in Maia Make

Last modified: October 19, 2026

Introduction

In Studio Pro 11.9 and above, OQL generation is part of Maia Make. In Studio Pro 11.8 and below, it is a separate tool called Maia for OQL.

To use this capability, you need an internet connection and must be signed in to Studio Pro.

Maia can generate and manage OQL (Object Query Language) queries. This simplifies query creation and reduces manual effort. For information on the current limitations, see the Limitations section below.

Working with OQL in Maia

Describe the data you need. For example, if you type Show all active orders with customer names, Maia generates the most relevant OQL query based on the data available in the same module.

Maia interprets your intent and provides a query that fits your requirements, helping you avoid manual query creation and common syntax errors.

In Studio Pro 11.9 and Above

In Studio Pro 11.9 and above, you can generate OQL queries with Maia in the Chat tab, which is enabled by default. There is no dedicated interface for OQL. For more information, see Maia Make Capabilities.

Studio Pro 11.13 and above, and 11.12.2 and above, include a setting to enable or disable OQL generation with Maia. OQL generation always uses the Mendix Platform regardless of the configured AI provider. To use OQL generation, you must enable both Enable Maia and Enable OQL Tool.
