合并基于同一表的两个查询，并在单个查询中显示结果

问题描述

我有这两个查询，我想将它们合并为一个
即:我的第一个查询显示了当年的结果，第二个查询显示了Issues_pending去年的余额，我如何将它们结合起来.

i have these two queries and i want to merge them into one
i.e: my first query show result of current year and second query show issues_pending balance of last year how can i combine them.

SELECT year,director, sum(issues_received) as Newly_Received,sum(issues_solved) as Solved,sum(issues_pending) as Remaining FROM subdivision_master where director=''dhbvn'' group by director,year

select SUM(convert(int,issues_pending)) as previous_balance from subdivision_master where year=CONVERT(int,year)-1

感谢您的任何帮助

推荐答案

SELECT  year,
        director,
        sum(issues_received)    as Newly_Received,
        sum(issues_solved)      as Solved,
        sum(issues_pending)     as Remaining,
        -- previous_balance (may have NULLs)
        (
        select  SUM(convert(int,issues_pending)) as previous_balance
        from    subdivision_master
        where   CONVERT(int,year) = CONVERT(int,a.year)-1
        )                       as previous_balance
FROM    subdivision_master a
where   director='dhbvn'
group
by      director,
        year

SELECT year,director, sum(issues_received) as Newly_Received,sum(issues_solved) as Solved,sum(issues_pending) as Remaining FROM subdivision_master where director='dhbvn' group by director,year UNION
select SUM(convert(int,issues_pending)) as previous_balance from subdivision_master where year=CONVERT(int,year)-1
