Question

How can I search the value "ABCD" inside two JSON array in a single column? This is multiple JSON data within square bracket Sample JSON data added below :

[{"id": "ABCD", "TEST1": "2002", "value": "test value1", "comment": ""}, {"id": "ABCD", "TEST2": "2003", "value": "test value2", "comment": ""}]

Answer 1

You can use Json_Search() function. In this function, we can set the second argument to one or all . We will use it as all to search for all the keys containing the given value.

SELECT JSON_SEARCH(json_column_name, 'all', 'ABCD');

DEMO - Schema (MySQL v5.7)

SET @json_column_name = '[{"id": "ABCD", "TEST1": "2002", "value": "test value1", "comment": ""}, {"id": "ABCD", "TEST2": "2003", "value": "test value2", "comment": ""}]';

SELECT JSON_SEARCH(@json_column_name, 'all', 'ABCD') AS result;

RESULT
