// 抓取json第1個跟第0個值
SELECT JSON_EXTRACT('[10, 20, [30, 40]]', '$[1]', '$[0]');
結果：20 | 10
// 抓取data欄位，json名稱為name的值
select json_extract(data,'$.name'),json_extract(data,'$.tel') from tab_json
直接抓取json第幾個值
CREATE TABLE tj10 (a JSON, b INT);
// 建立資料
INSERT INTO tj10 VALUES ("[3,10,5,17,44]", 33), ("[3,10,5,17,[22,44,66]]", 0);
// 抓取
SELECT a->"$[4]" FROM tj10;
結果：44 | [22,44,66]
