使用sql将各组范围依一定各数分组，并依此编号

Question

想请问各位:
我有一个资料表，有以下这几个columns:post_no, tkt_no, plic, unit
之後我写了一段sql 专门是找各post_no及tkt_no最大跟最小，其中post_no及tkt_no是相对应的。并依zone分组。
sql如下

select min(post_no) +'~'+ max(post_no) as post_no, min(tkt_no) +char(10) + char(13) +  max(tkt_no) as tkt_no, plic, max(unit)
from TEST
where date = '20170721'
group by zone
order by post_no

结果如下:

现在我想要将710001~712987及720001~720645分成每1200一组，不满1200的自成一组，
结果如下:

想请问sql的撰写方式需要使用什麽样的方式撰写，请各位给我一个方向。
