MySQL使用json_extract 函数过滤满足条件的json串

 字段中存的字符串为json串，需要取出"is_split": "0"的行，

}

方法一 用like

SELECT
*
FROM
loan_info a
LEFT JOIN loan_product_fund_record b ON a.ID = b.LOAN_ID
LEFT JOIN third_credit_query_order c ON b.RISK_ID = c.ORDER_NO
WHERE
a.LENDING_TAG = 'jlxd'
AND a.LOAN_STATUS IN ('002001007', '002001005')
AND b.IS_SPLIT = 0
AND c.QUERY_RESULT like '%\"is_split\"\:\"0\"%';

方法二：json_extract

SELECT
*
FROM
loan_info a
LEFT JOIN loan_product_fund_record b ON a.ID = b.LOAN_ID
LEFT JOIN third_credit_query_order c ON b.RISK_ID = c.ORDER_NO
WHERE
a.LENDING_TAG = 'jlxd'
AND a.LOAN_STATUS IN ('002001007', '002001005')
AND b.IS_SPLIT = 0
AND json_extract (QUERY_RESULT, '$.result.fund_result.is_split') = '0'
