However, the OPENJSON function can return any complex object.įinally, there is a FOR JSON clause that can format any result set returned by SQL query as JSON text:Ĭheck out the other posts in this four-part series in the links below (as they become available), or learn more in the SQL Server 2016 blogging series. JSON functions in SQL Server enable you to analyze and query JSON data, transform JSON to relational format, and export SQL query results as JSON text. In this example, string values from the tags array are returned. The OPENJSON function enables you to reference some array in JSON text and return elements from that array: JSON built-in functions use JavaScript-like syntax to reference values and objects in JSON text via second parameter.

The JSON_VALUE function returns one scalar value from JSON text (e.g. This query will return “Basic”, “Bristol”, and values. Now, we can extract values and objects from JSON text using the JSON_VALUE and JSON_QUERY functions: In the following Transact-SQL code, we will define a text variable where we will put JSON text: Finally, there is the FOR JSON clause that enables you to format query results as JSON text. Any SQL query can be executed on the returned result set. For more advanced querying and analysis, the OPENJSON function can transform an array of JSON objects into a set of rows. If you have JSON text, you can extract data from JSON or verify that JSON is properly formatted using built-in functions JSON_VALUE, JSON_QUERY, and ISJSON. JSON functions in SQL Server enable you to analyze and query JSON data, transform JSON to relational format, and export SQL query results as JSON text. In this post, we will present a high-level overview of JSON functionality in SQL Server 2016.
