SQL Server分组按周查询

Question

请参阅下面的查询和结果

(SELECT count(*) as Count, p.regionid, a.territory,
CASE WHEN DATEPART(day,p.prodate) < 8 THEN '1' 
  ELSE CASE WHEN DATEPART(day,p.prodate) < 15 then '2' 
    ELSE CASE WHEN  DATEPART(day,p.prodate) < 22 then '3' 
      ELSE CASE WHEN  DATEPART(day,p.prodate) < 29 then '4'     
       ELSE '5'   
      END
    END
  END
END as WeekNumber 
from pros p 
inner join
GTS_Account a 
on a.locationGTSNo = p.BillToCustNo
  where a.account like '%abc%' and
  p.prodate between '2014-02-01' and '2014-02-28' 
group by p.ProDate,p.regionid,a.territory)

结果

这显示了一周中每天的数据，我只是希望它显示每个地区/每周不是每天的总数。 谢谢

3-13-14我想显示这些数据的月份和年份列，请在下面的查询中，每个区域/周应该只显示一行。

SELECT convert(nvarchar,DATEPART(YYYY,p.prodate))  + ' ' +

Answer 1

您只需要按照您选择的相同内容进行分组，而不是p.prodate

此外，您不需要多个WHEN的嵌套案例语句

SELECT Count(*) AS Count, 
       p.regionid, 
       a.territory, 
       CASE 
         WHEN Datepart(day, p.prodate) < 8 THEN '1' 
         WHEN Datepart(day, p.prodate) < 15 THEN '2' 
         WHEN Datepart(day, p.prodate) < 22 THEN '3' 
         WHEN Datepart(day, p.prodate) < 29 THEN '4' 
         ELSE '5' 
       END      AS WeekNumber 
FROM   pros p 
       INNER JOIN gts_account a 
               ON a.locationgtsno = p.billtocustno 
WHERE  a.account LIKE '%abc%' 
       AND p.prodate BETWEEN '2014-02-01' AND '2014-02-28' 
GROUP  BY CASE 
            WHEN Datepart(day, p.prodate) < 8 THEN '1' 
            WHEN Datepart(day, p.prodate) < 15 THEN '2' 
            WHEN Datepart(day, p.prodate) < 22 THEN '3' 
            WHEN Datepart(day, p.prodate) < 29 THEN '4' 
            ELSE '5' 
          END, 
          p.regionid, 
          a.territory 

如果你的case语句足够讨厌，你也可以使用with子句使它更清洁

WITH cte 
     AS (SELECT 
                p.regionid, 
                a.territory, 
                CASE 
                  WHEN Datepart(day, p.prodate) < 8 THEN '1' 
                  WHEN Datepart(day, p.prodate) < 15 THEN '2' 
                  WHEN Datepart(day, p.prodate) < 22 THEN '3' 
                  WHEN Datepart(day, p.prodate) < 29 THEN '4' 
                  ELSE '5' 
                END AS WeekNumber 
         FROM   pros p 
                INNER JOIN gts_account a 
                        ON a.locationgtsno = p.billtocustno 
         WHERE  a.account LIKE '%abc%' 
                AND p.prodate BETWEEN '2014-02-01' AND '2014-02-28') 
SELECT Count(*) As Count,  
       regionid, 
       territory, 
       weeknumber 
FROM   cte 
GROUP  BY weeknumber, 
          regionid, 
          territory
