# QBCondition

## Overview

The `QBCondition` class is a wrapper for conditions used in a `QBSelect` query. It supports various comparison operations such as equality, ranges, patterns, and inclusion (`compare`, `in`, `like`, `between`). These conditions help refine query results by enabling precise filtering.

The `parent` property provides access to the query builder's parent table clause, which could be a query or a join clause. The `root` property allows navigation to the root query builder, facilitating integration with larger query structures.

For more information about constructing and executing queries, refer to the [QBSelect](https://docs.servoy.com/reference/servoycore/dev-api/database-manager/qbselect) section of this documentation.
