如何在MySQL里构造SQL语句，自动给查询出来的结果加一列从1开始的序号列

两种办法：

第一种：快捷

select (@i:=@i+1) as i,a.* from zakk_carinfo_201811 a,(select @i:=0) as it
where CI_ThroughTime between "2018-11-28 00:00:00" and "2018-11-28 23:59:59";

zakk_carinfo_201811是表名，这样设计出来的语句查询速度不慢

第二种：啰嗦

set @rownum=0;

select @rownum:=@rownum+1 as rownum, a.* from zakk_carinfo_201811 a limit 1,1000;
