分页语句的执行顺序

基于用户名分页查询操作语句

        select * from sys_logs 
        where username like concat('%','admin','%')
        order by createdTime desc
        limit 0,10 ;

    
        select * from sys_logs 
        where username like concat('%','admin','%')
        order by createdTime desc
        limit 0,10 
    

等价于

    
        select * from sys_logs 
        where username like concat('%',#{username},'%')
        order by createdTime desc
        limit #{startIndex},#{pageSize}
