SQL查询在两周之间返回0

Question

我有这个查询有效，但结果不像我想要的

只返回有数据的年份和周数，我想将0返回到结果

例如，

返回

year    week   totalstop
2017    50     7
2018    1      3
2018    3      5

但我想返回

year    week   totalstop
2017    50     7
2017    51     0
2017    52     0
2018    1      3
2018    2      0
2018    3      5

等等

这是当前查询

SELECT year(Stopdate)[year],datepart(week,date1) [week],sum(stop) totalstop 
        from Table1 where 
        building in (select item from dbo.fn_Split('A1,A2,A3,A4,A5',',')) 
        and 
        date1 between '2017-12-12' and '2018-05-08' 
        and grp = 1
        group by year(date1),datepart(week,date1)
        order by year(date1),[week]

iam使用ms sql-server 2016

需要帮助来根据我的想法修改它以满足我的需求。
