To fix this issue First modify your query to add a WHERE clause to filter down the results. Then once you have the results, you can turn it into JSON 1 of 2 ways.

hop of those help? If you only have numbers in the fields, you can alter your regexp to only take values where the string you are looking for (here the '3') does not have another number immediately close to it :
code :
SELECT * FROM `pages` WHERE access REGEXP '([^"0-9])3([^"0-9])'

Does that help You could use JSON_EXTRACT to find the values of activity and compare them:
code :
$sql = "SELECT * 
        FROM table
        WHERE JSON_EXTRACT(column,  '$[*].activity') LIKE '%".$term."%'";

Does that help I tested the following with MySQL 8.0. It uses functions that seem to be present in MariaDB according to its documentation, but I don't have a MariaDB instance to test.
code :
SELECT * FROM mytable;
| data                                                                                                                                                                                                                               |
| {"1": {"text": "Item1", "value": 1, "isActive": 0, "textDisplay": ""}, "2": {"text": "Item2", "value": 2, "isActive": 1, "textDisplay": ""}, "3": {"text": "Item3", "value": 3, "isActive": 1, "textDisplay": ""}, "nextValue": 4} |

SELECT JSON_UNQUOTE(JSON_EXTRACT(JSON_EXTRACT(data, REPLACE(JSON_UNQUOTE(JSON_SEARCH(data, 'one', 'Item2')), '.text', '')), '$.value')) AS value FROM mytable;
| value |
| 2     |
SELECT j.* FROM mytable2, 
JSON_TABLE(mytable2.data, '$[*]' 
    `text` VARCHAR(20) PATH '$.text',
    textDisplay TEXT PATH '$.textDisplay',
    value INT PATH '$.value',
    isActive BOOL PATH '$.isActive'
) AS j

| rowid | text  | textDisplay | value | isActive |
|     1 | Item1 |             |     1 |        0 |
|     2 | Item2 |             |     2 |        1 |
|     3 | Item3 |             |     3 |        1 |
select * from mytable2;
| data                                                                                                                                                                                                |
| [{"text": "Item1", "value": 1, "isActive": 0, "textDisplay": ""}, {"text": "Item2", "value": 2, "isActive": 1, "textDisplay": ""}, {"text": "Item3", "value": 3, "isActive": 1, "textDisplay": ""}] |
  `text` VARCHAR(20), 
  textDisplay TEXT, 
  value INT, 
  isActive BOOL
VALUES (1, 'Item1', '', 1, 0),
       (2, 'Item2', '', 2, 1),
       (3, 'Item3', '', 3, 1);
SELECT value FROM Items WHERE `text` = 'Item2';

How can I update specific value from MySQL JSON column

By : user2730761
Date : March 29 2020, 07:55 AM
may help you . I'm trying to update a specific value in JSON array from a MySQL column by searching for specific ID, I want it to be dynamic without specifying array key. , Try (adjust everything you consider necessary):
code :
UPDATE `myTable`
        `position` FOR ORDINALITY,
        `ID` INT PATH '$.ID'
    ) `der`
  CONCAT('$[', `der`.`position` - 1, '].OD'),
WHERE `der`.`ID` = 63010092;
