MySQL特异功能之：Impossible WHERE noticed after reading const tables

用EXPLAIN看MySQL的执行计划时经常会看到Impossible WHERE noticed after reading const tables这句话,意思是说MySQL通过读取"const tables",发现这个查询是不可能有结果输出的.比如对下面的表和数据: create table t (a int primary key, b int) engine = innodb; insert into t values(1, 1); insert into t values(…
