Hello,
In this article, we will learn how to index JSON-type data on SQL Server to perform fast searches.
As we know, JSON-type data is actually string expressions that can be stored as NVARCHAR(Max) on SQL Server.
The biggest advantage of using JSON is that it does not require a structured format in a field, and when you want to store more and different information in the future, you do not need to make changes to the database structure.
For example, in a product list, the material information of the lid used in one product’s features may not be necessary in another. You can add them later. When you want to query, you can only retrieve the ones that are present.
