带有count和case语句的SQL查询

我需要找出有多少人在2006年、2007年、2008年三个不同年份的申报期结束日期后60天内、120天内、180天内、180天以上提交了完整的纳税申报表

下面的声明将给我所有的年 我需要每年和每种可能性的计数。。 无论如何，我可以做到这一点，没有2个查询

SELECT YEAR(A.FPE) AS "YEAR"
,CASE                                              
  WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 60 THEN '2 ' 
  WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 120 THEN '4 '
  WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 180 THEN '6 '
  WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) > 180 THEN '6+'
 END AS "NBR MTH"                                  
WHERE A.FPE BETWEEN '2006-01-01' AND '2008-12-31'

我需要你的帮助

非常感谢

请按您的案例陈述所代表的栏目分组：

SELECT 
  YEAR(A.FPE) AS "YEAR",
  CASE                                              
    WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 60 THEN '2 ' 
    WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 120 THEN '4 '
    WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 180 THEN '6 '
    WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) > 180 THEN '6+'
  END AS "NBR MTH",
  COUNT(1) AS "TOTAL"
FROM Table
WHERE 
  A.FPE BETWEEN '2006-01-01' AND '2008-12-31'
GROUP BY
  "YEAR",
  "NBR MTH"

---

此查询将为您提供每个唯一年份/NBR MTH组合的每条记录的计数。

实际上，大多数DBMS不允许使用别名进行分组，因此必须使用别名

...
GROUP BY 
  YEAR(A.FPE),
  CASE                                              
    WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 60 THEN '2 ' 
    WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 120 THEN '4 '
    WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 180 THEN '6 '
    WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) > 180 THEN '6+'
  END

与简单的“按年分组”不同，这将为丢失的记录选择0，例如，如果2008年没有6+个记录，则写入

   SELECT YEAR(A.FPE) AS "YEAR",
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 60 
                  THEN 1 Else 0 End) SixtydayCount,  
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 120 
                  THEN 1 Else 0 End) OneTwentyDayCount,
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 180 
                  THEN 1  Else 0 End) OneEightyDayCount,
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) > 180 
                  THEN 1 Else 0 End)  OverOneEightyCount  
    From Table A
    WHERE A.FPE BETWEEN '2006-01-01' AND '2008-12-31'
    Group By YEAR(A.FPE)

如果你希望120天和180天的计算只包括60岁以上和120岁以下的人，等等

     SELECT YEAR(A.FPE) AS "YEAR",
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 60 
                  THEN 1 Else 0 End) SixtydayCount,  
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) Between 60 And 119 
                  THEN 1 Else 0 End) OneTwentyDayCount,
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) Between 120 And 179 
                  THEN 1  Else 0 End) OneEightyDayCount,
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) >= 180 
                  THEN 1 Else 0 End)  OverOneEightyCount  
    From Table A
    WHERE A.FPE BETWEEN '2006-01-01' AND '2008-12-31'
    Group By YEAR(A.FPE)

总和将超过100%：<60意味着<120甚至更多。我认为@op的意思是从0到60，从61到120等等。@Quassnoi，是的，添加了第二个查询以显示如何进行排他计数。。。但你们是如何在评论中突出显示文本的呢？请告诉我…@Charles Bretana：就像你在帖子中所做的那样，把文本用背勾和星号括起来。我知道这是一个古老的答案，但这正是我想要的。

     SELECT YEAR(A.FPE) AS "YEAR",
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) < 60 
                  THEN 1 Else 0 End) SixtydayCount,  
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) Between 60 And 119 
                  THEN 1 Else 0 End) OneTwentyDayCount,
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) Between 120 And 179 
                  THEN 1  Else 0 End) OneEightyDayCount,
       Sum(CASE WHEN DAYS(A.FIL_DT) - DAYS(A.FPE) >= 180 
                  THEN 1 Else 0 End)  OverOneEightyCount  
    From Table A
    WHERE A.FPE BETWEEN '2006-01-01' AND '2008-12-31'
    Group By YEAR(A.FPE)
