# JSColumn

## Overview

The `JSColumn` is a scripting object that represents a column in a data source, accessible through root objects like `datasources` and `databaseManager`. It provides methods for retrieving and managing metadata, properties, and flags associated with the column.

The object allows developers to interact with column-specific attributes such as data provider IDs, SQL names, types, lengths, and sequence configurations. It supports checking column flags, including primary key (`PK_COLUMN`), UUID, or tenant-specific columns, and retrieving the column’s row identifier type. Additionally, it provides access to design-time configurations like default formats, foreign key references, titles, and descriptions.

By enabling advanced operations such as quoting SQL identifiers and retrieving raw JDBC types, `JSColumn` ensures integration with the underlying database schema while maintaining scripting simplicity within the Servoy environment.
