    You can use dynamic SQL, but when I see things like that I always wonder "what does the poster really want to achieve"? May be there is a better solution that does not require dynamic SQL.

    I have an article about here. It is long, but dynamic SQL is an advanced topic.

    Hi @Mohamed Farook ,

    > I need JSON value from query string in table column it's possible ?

    Yes. If you have JSON text that's stored in database tables, you can read or modify values in the JSON text by using some built-in functions. Such as OPENJSON, JSON_QUERY etc. Please refer to the MS document JSON data in SQL Server or the blog Basics of Working with JSON in SQL Server to get more information.

    If I misunderstood, please let me know.
