Instead of using regexp like so: | |
ancestors column would be something like: {"category": 1} | |
WHERE `ancestors` REGEXP '(.*\"category\":\"1\")' | |
Use the JSON functions: | |
WHERE JSON_EXTRACT(`ancestors`, 'category') = 1 | |
Arrays: | |
WHERE JSON_SEARCH(JSON_EXTRACT('{"categories": [1,2,3]}', 'categories'), "1") != null | |
