JSON_EXTRACT MariaDB

Question

我需要從json數據進行查詢時遇到問題。

我的json數據如下所示：

{"groups":[{"groupid":"3","group_name":"test group","group_type":"user","office":"1"},{"groupid":"4","group_name":"test group 1","group_type":"user","office":"1"},{"groupid":"21","group_name":"test group 2","group_type":"directory","office":"0"}]}

是否可以使查詢僅返回office = 1的組ID

目前我已經做到了，但不知道如何查詢辦公室。

select json_extract(test,'$.groups[*].groupid') as groupid from test;

Answer 1

嘗試：

SELECT CONCAT('
  SELECT JSON_EXTRACT(`doc_text`, ',
    REPLACE(TRIM('[' FROM TRIM(']' FROM
        JSON_SEARCH(doc_text, 'all', '1', NULL, '$.groups[*].office')
        )
      ),
      'office',
      'groupid'
    ), ') `groupid` FROM `docs`'
) INTO @`sql`
FROM `docs`;
