主要是那个查询语句的问题，以下语句如果查询的记录在1700条左右的时候，需要35秒
SELECT * FROM `sale_orders` T
WHERE (`number`='' or `number`=81)
AND 1=(select count(*) from `sale_orders`
where (`number`='' or `number`=81)
AND `recipient_name`=T.`recipient_name`
AND `ship_address_1`=T.`ship_address_1`)
AND `package_area`='SZ'
GROUP BY `recipient_name` , `ship_address_1`
请问怎么优化啊？显示一天的数据需要75秒，那一个月的数据不是等吃一餐饭还没显示完
回复讨论(解决方案)
具体情况需具体分析，毕竟不是在做文字游戏
调试查询指令应听从 EXPLAIN 的建议
尽量少用select * ，需要哪个字段查哪个，还有，加索引
数据表需要优化。
可否desc给大家看看呢
