How to query Json objects in MySQL?

Is it possible to directly query a JSON object in MySQL?

It is not possible to directly query a JSON object in MySQL, as MySQL does not have native support for JSON data type. However, there are some workarounds that you can use to query JSON data in MySQL.

One option is to use the JSON_EXTRACT() function to extract a scalar value from a JSON column. For example:

SELECT JSON_EXTRACT(json_column, ‘$.key’)
FROM table
WHERE JSON_EXTRACT(json_column, ‘$.key’) = ‘value’;

Another option is to use the JSON_SEARCH() function to search for a specific value within a JSON column, and then use JSON_EXTRACT() to extract the value. For example:

SELECT JSON_EXTRACT(json_column, JSON_SEARCH(json_column, ‘one’, ‘value’))
FROM table;

You can also use the JSON_CONTAINS() function to check if a JSON column contains a specific value. For example:

SELECT *
FROM table
WHERE JSON_CONTAINS(json_column, ‘value’, ‘$.key’)

How about Nested JSONS ?

To query a nested JSON object in MySQL, you can use the JSON_EXTRACT() function to extract the value of the nested key and then use comparison operators to filter the results.

Here is an example of how to query a nested JSON object in MySQL –

SELECT *
FROM table
WHERE JSON_EXTRACT(json_column, ‘$.nested.key’) = ‘value’;

In this example, the JSON_EXTRACT() function is used to extract the value of the key nested within the nested object within the json_column. The resulting value is then…
