mysql select in 怎么优化
2017年7月10日 22:36:54 星期一
原理: 把select where in 变换成 "where = " 或者 "where between and " 这样的子句, 然后用union all 拼接, 一次查询
环境:
php7,
summerPHP框架,
代码部署在杭州(华东)阿里云的机器上,
mysql数据库部署在青岛(华北),
表的记录数量为8200+,
id是主键,hanzi不在索引中
每次id的生成都是随机数, 所以数据比较分散
结果:
union all 总是慢...... 下边是in的数量为10, 50, 100, 200, 300的计算结果
有此优化想法的同学可以绕道了, 或者我这里有哪里不对的地方也请指出来, 让我哭一会先.....
1. in的数量在10以下的时候, 直接in快一点
2. in的数量是50, union all 总是稍慢
