To retrieve rows as JSON objects in SQL, you can use the FOR JSON PATH clause in SQL Server or JSON_OBJECT function in MySQL. Here's a basic example using SQL Server: SELECT * FROM YourTable FOR JSON PATH This query will return each row as a JSON object. If you have hundreds of rows, they will be formatted as an array of JSON objects. Remember to adjust the query to fit your table structure and filtering needs.

you can use the FOR JSON clause in Microsoft SQL Server or a similar clause in other databases that support JSON output. Here's an example using the FOR JSON AUTO clause in Microsoft SQL Server: SELECT column1, column2, ... FROM table_name WHERE condition FOR JSON AUTO; This query will return the result set in JSON format. The FOR JSON AUTO clause automatically generates a JSON representation of the result set based on the table structure. Here's a simple example: SELECT FirstName, LastName, Age FROM Persons WHERE Age > 25 FOR JSON AUTO; This would return a JSON array of objects representing the selected data: [ {"FirstName": "John", "LastName": "Doe", "Age": 30}, {"FirstName": "Jane", "LastName": "Smith", "Age": 28}, ... ] Note that the exact syntax may vary between different database systems, and some databases might not support JSON output directly. If you're using a different database, please refer to its documentation for the specific syntax for retrieving JSON-formatted results.

Hello Jaya, Getting each row value in json format or want to export data from SQL Server as JSON, you need to add FOR JSON clause to a SELECT statement. Below is a sample query that uses PATH mode FOR JSON clause. SELECT * FROM table FOR JSON PATH; Also you can use JSON_EXTRACT function that allows you to extract a value from a JSON string. Here is an example of how to use the JSON_EXTRACT function in a SELECT statement: SELECT JSON_EXTRACT(json_column, '$.key1.key2') FROM table WHERE json_column IS NOT NULL; Hope this helps!
