mysql-慢sql优化

1.

SELECT PLAT_BATCH_CODE FROM t_fee_fact_record t WHERE t.SALES_CHANNEL = ? AND t.PAY_STATUS IN (?) AND t.FEE_STATUS != ? AND t.ISCLEAN = ? AND t.processing = ? AND TIMESTAMPDIFF(MINUTE, t.OPERATE_TIME, now()) >= ?

 优化建议：

1）.
t.FEE_STATUS != '1' 改成
AND t.FEE_STATUS in('0','2','3')
2）.
java中计算TIMESTAMPDIFF(MINUTE, t.OPERATE_TIME, now())

2.

SELECT weixin_id FROM wcap_user_binding_rs WHERE check_status IS NULL ORDER BY bindingtime ASC LIMIT ?

 优化建议：

check_status 改为默认空字符串
