需要连续统计最新日期开始，为0的数。比如上面统计结果应该是
1 B211001024014 4
2 B211001024011 3
3 B211001024013 2
SQL如下
?
SELECT yhh,MAX(s) nums from (danielinbiti
select a.*
,case when @f=0 then @cust:=yhh end t1
,@f:=1
,case when yhh!=@cust then @flag:=0 end t
,case when ysl!=0 and @flag=0 then @flag:=1 end f
,case when ysl=0 and @flag=0 then @cnt:=@cnt+1 else @cnt:=0 end c
,@cnt s,@cust:=yhh,@flag f2 from (
select * from jqfk order by yhh,cbrq desc
) a,(select @cust:='') r,(select @cnt:=0) r2,(select @flag:=0) r3,(select @f:=0) r4
) k where f2=0 group by yhh order by nums desc
