In this article, we are exploring JSON_QUERY() function using various examples. You can refer to JSON for these articles. We explored JSON_VALUE() and JSON_MODIFY() functions in my previous articles. We can view these functions in the following image of Microsoft docs. JSON_QUERY: It extracts an array or string from JSON in SQL Server.You should go through Modifying JSON data using JSON_MODIFY() in SQL Server for this function JSON_MODIFY(): It modifies values in the JSON Data.JSON_VALUE(): It extracts a scalar value from the JSON data.ISJSON(): we can check valid JSON using this function.SQL Server provides the following JSON functions to work with JSON Data: In the below example, we have a key (Name),Īnd its value is a JSON object (nested JSON) In JSON, each object is enclosed by curly brackets(). For example “Name”:”Rajendra”īefore we go further, I will give a small overview of JSON object and array. We can have a string, object, array, Boolean or number data format in a valueĮach key should use colon (:) to segregate from the values. Server JSON functions: a bridge between NoSQL and relational worlds for more detailsĮach key should be enclosed in a double-quote It is a bridge between No-SQL and relational databases.

It becomes necessary for SQL database administrators as well to understand JSON and use SQL Server function in These NoSQL databases primarily uses JSON structuredĭata. If you are familiar with Amazon Web Service, DynamoDB, MongoDB, Couchbaseĭatabases, you should be familiar with the JSON documents.

JavaScript Object Notation (JSON) is an accessible format for representing data in a structured way. Secondly, we read JSON String stored in a file using json.loads() for that we first convert the JSON file into a string using the file handling same as in the above example and then convert it into the string using read() function and rest of the procedure is same as we follow before using json.loads() method.In this article, we will explore JSON_QUERY() functions in SQL Server to extract JSON objects and array from the Firstly, we have a JSON string stored in a variable ‘j_string’ and convert this JSON string into a Python dictionary using json.loads() method that is stored in the variable ‘y’ after that we print it. This example shows reading from both string and JSON file using json.loads() method. Return Type: It returns the Python object. Parameter: it takes a string, bytes, or byte array instance which contains the JSON document as a parameter (S). This method returns the content of the file. json.loads() does not take the file path, but the file contents as a string, to read the content of a JSON file we can use fileobject.read() to convert the file into a string and pass it with json.loads(). If we have a JSON string, we can parse it by using the json.loads() method.
