Question

我有QUERY：

 SELECT dept,csedept_name,January,February,March,April,May,June,July,August,September,October,November,December
FROM (SELECT CAST(employeedept AS INT) as dept,
        ROUND(AVG(case when rating1>0 THEN CAST(rating1 AS FLOAT) ELSE null END), 2) as q1,
        ROUND(AVG(case when rating2>0 THEN CAST(rating2 AS FLOAT) ELSE null END), 2) as q2,
        ROUND(AVG(case when rating3>0 THEN CAST(rating3 AS FLOAT) ELSE null END), 2) as q3,
        ROUND(AVG(case when rating4>0 THEN CAST(rating4 AS FLOAT) ELSE null END), 2) as q4,
        ROUND(AVG(case when rating5>0 THEN CAST(rating5 AS FLOAT) ELSE null END), 2) as q5,
count(*) as 'totalstars',month_cse= datename(month,execoffice_date),YEAR_cse =YEAR(execoffice_date)
        FROM CSEReduxResponses
        WHERE 
      execoffice_status = 1 
      and employeedept =17
        group by employeedept,month(execoffice_date),YEAR(execoffice_date),DATENAME(month,execoffice_date)

      ) 
    AS r JOIN CSEReduxDepts d
ON d.csedept_id = r.dept and d.csedept_id=17
PIVOT( SUM(q1)
    FOR [month_cse] IN (
        [January],[February],[March],[April],[May],[June],[July],[August], [September],[October],[November],[December]
        )) AS pvt

根据部门的不同，每月获得平均值。在上面的查询中我得到了＆＃39; q1＆＃39;并显示该月和部门的正确数字但它每个月显示一行，我只能显示＆＃39; q1＆＃39;当我想展示q1-q5。

我可能采取多长/错误的方式来做这件事，也许使用枢轴是错误的方式。

有没有办法可以在相应的月份添加q1-q5并显示？

这个查询怎么样：

查询1 ：

;with
years as 
(select distinct year(execoffice_date) y from CSEReduxResponses),
months as

union select 'February', 2 n
union select 'March', 3 n
union select 'April', 4 n

union select 'October', 10 n
union select 'November', 11 n
union select 'December', 12 n),
cse as (SELECT CAST(employeedept AS INT) as dept,
        ROUND(AVG(case when rating1>0 THEN CAST(rating1 AS FLOAT) ELSE null END), 2) as q1,
        ROUND(AVG(case when rating2>0 THEN CAST(rating2 AS FLOAT) ELSE null END), 2) as q2,
        ROUND(AVG(case when rating3>0 THEN CAST(rating3 AS FLOAT) ELSE null END), 2) as q3,
        ROUND(AVG(case when rating4>0 THEN CAST(rating4 AS FLOAT) ELSE null END), 2) as q4,
        ROUND(AVG(case when rating5>0 THEN CAST(rating5 AS FLOAT) ELSE null END), 2) as q5,
        count(*) as 'totalstars', YEAR(execoffice_date) as YEAR_cse, month(execoffice_date) as m_cse
        FROM CSEReduxResponses
        group by employeedept, month(execoffice_date), YEAR(execoffice_date)

      ) 
SELECT csedept_id, d.csedept_name, years.y, months.m, q1, q2, q3, q4, q5, totalstars
FROM years cross join months
cross join CSEReduxDepts d
left join cse on
months.n = cse.m_cse and d.csedept_id = cse.dept
where d.csedept_id = 17
order by years.y, months.n, csedept_id, csedept_name

您甚至可以评论最后一个where d.csedept_id = 17子句以检索所有部门的详细信息。我不认为每个月在单独的列中显示q1，q2，q3，q4，q5，TOTALSTARS是明智的。在这种情况下，您将最终得到60列

使用和使用带有多个列的Pivot？
