What type of queries can be written using the Historian Client Query?

The Historian Client Query allows users to write custom SQL queries, which provides flexibility and control over how data is accessed and manipulated within the AVEVA Historian. This is essential for users who need to tailor their data retrieval processes according to specific business requirements or analytical needs. By using custom SQL queries, users can specify exactly what data they want to retrieve, filter results based on specific conditions, and even perform complex calculations directly within the query.

This capability significantly enhances the analytical power of the Historian, as users can gain insights from the data that go beyond predefined options or graphical interfaces, which might not support the exact requirements of every scenario. Custom SQL queries enable advanced data handling, making it an indispensable feature for users who are familiar with writing SQL and want to leverage the full potential of the Historian system.

While other types of queries may exist within the tool, such as predefined or graphical queries, the ability to create custom SQL queries distinguishes the versatility of the Historian Client Query and supports a broader range of use cases.
