**Updating a JSON value in SQL involves using the JSON_VALUE and JSON_MODIFY functions in conjunction with an UPDATE statement. By using these functions, you can easily update specific values within a JSON column in your SQL database.**<\/p>\n

JSON (JavaScript Object Notation) has become a popular data format for storing and exchanging information in modern applications. With the increasing use of JSON in databases, it is essential to know how to work with JSON data effectively. In SQL, updating JSON values can be done using a combination of JSON functions and SQL commands. Here is a step-by-step guide on how to update JSON values in SQL:<\/p>\n

1. **Identify the JSON column:** The first step is to identify the JSON column in your table that you want to update.<\/p>\n

2. **Construct the UPDATE statement:** Use the UPDATE statement to specify the table and column you want to update.<\/p>\n

3. **Use the JSON_VALUE function:** The JSON_VALUE function extracts a scalar value from a JSON string. Use this function to retrieve the existing JSON value that you want to update.<\/p>\n

4. **Use the JSON_MODIFY function:** The JSON_MODIFY function updates the JSON value in the specified JSON string. Use this function to modify the JSON value retrieved using JSON_VALUE.<\/p>\n

5. **Specify the new value:** Provide the new value that you want to update the JSON column with.<\/p>\n

6. **Combine JSON_VALUE and JSON_MODIFY:** Use both functions in your UPDATE statement to extract the existing JSON value, modify it, and update the JSON column with the new value.<\/p>\n

7. **Execute the UPDATE statement:** Run the UPDATE statement to update the JSON value in the specified column.<\/p>\n

8. **Verify the update:** Check the table to ensure that the JSON value has been updated as desired.<\/p>\n

Updating JSON values in SQL can be a powerful tool for manipulating JSON data within your database efficiently.<\/p>\n
