SELECT REPLACE(lh,'-','0')lh,CAST(ylh AS INT)ylh FROM 表名

with cte as 
(select '16-5' as lh,'02' as ylh union all
 select '16-12' as lh,'02' as ylh union all
 select '17-8' as lh,'09' as ylh union all
 select '11-02' as lh,'05' as ylh union all
 select '19' as lh,'01' as ylh union all
 select '221-3' as lh,'11' as ylh )
 select case when CHARINDEX('-',lh)=0  then lh 
  when LEN(lh)-CHARINDEX('-',lh)=1 then REPLACE(lh,'-','0')
 when LEN(lh)-CHARINDEX('-',lh)=2 then REPLACE(lh,'-','')
 end as lh,convert(int,ylh) as yhl from cte 

--结果
lh          yhl
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- -----------
1605       2
1612       2
1708       9
1102       5
19         1
