查找两个日期范围之间缺少的日期在SQL

-1

ID  StartDate    EndDate 
AAA  2017-03-17 00:00:00.000 2017-03-19 00:00:00.000 
BB  2017-06-20 00:00:00.000 2017-06-25 00:00:00.000  
CC  2017-05-13 00:00:00.000 2017-05-17 00:00:00.000 
DD  2017-06-20 00:00:00.000 2017-05-27 00:00:00.000 
EE  2017-03-01 00:00:00.000 2017-03-05 00:00:00.000 
FF  2017-08-07 00:00:00.000 2017-08-11 00:00:00.000

我需要在这些范围和输出表之间缺少的日期的表应该像

ID Date 
AAA 2017-03-17 00:00:00.000 -- Start date for AAA 
AAA 2017-03-18 00:00:00.000 
AAA 2017-03-19 00:00:00.000 -- End date for AAA 
BB 2017-06-20 00:00:00.000 -- start date for BB 
BB 2017-06-21 00:00:00.000 
BB 2017-06-22 00:00:00.000 
BB 2017-06-23 00:00:00.000 
BB 2017-06-24 00:00:00.000 
BB 2017-06-25 00:00:00.000 -- End date for BB

如果他们都开始在午夜，何苦存储时间成分呢？也就是说，这是应用程序代码 – Strawberry

的工作1. Mysql和ms sql server是具有不同sql实现的两种不同产品。你使用哪一个？如果这些问题不包含任何诚实的解决问题的尝试，通常在这里就不会得到很好的答案。 – Shadow

时间在这里没关系。这就像留下数据库的员工从开始日期到结束日期离开数据库。所以我需要在@Strawberry –

您需要添加循环以获取开始和结束日期之间的日期，例如：

  DECLARE @table table (ID Varchar(50), StartDate datetime,EndDate datetime) 

      insert into @table values ('AAA','2017-03-17 00:00:00.000',' 2017-03-19 00:00:00.000') 
      insert into @table values ('BB','2017-06-20 00:00:00.000 ',' 2017-06-25 00:00:00.000') 
      insert into @table values ('CC','2017-05-13 00:00:00.000 ',' 2017-05-17 00:00:00.000') 
      insert into @table values ('DD','2017-06-20 00:00:00.000 ',' 2017-05-27 00:00:00.000') 
      insert into @table values ('EE','2017-03-01 00:00:00.000 ',' 2017-03-05 00:00:00.000') 
      insert into @table values ('FF','2017-08-07 00:00:00.000 ',' 2017-08-11 00:00:00.000') 


      SELECT * FROM @table 

      SELECT id, StartDate FROM @table WHERE id='AAA' 
      union all 
      SELECT id, Dateadd(day,1,startdate) AS date FROM @table WHERE id='AAA' AND Dateadd(day,1,startdate)<EndDate 
      union all 
      SELECT id, EndDate FROM @table WHERE id='AAA' 
      union all 

      SELECT id, StartDate FROM @table WHERE id='BB' 
      union all 
      SELECT id, Dateadd(day,1,startdate) AS date FROM @table WHERE id='BB' AND Dateadd(day,1,startdate)<EndDate 
      union all 
      SELECT id, EndDate FROM @table WHERE id='BB' 
      union all 

      SELECT id, StartDate FROM @table WHERE id='CC' 
      union all 
      SELECT id, Dateadd(day,1,startdate) AS date FROM @table WHERE id='CC' AND Dateadd(day,1,startdate)<EndDate 
      union all 
      SELECT id, EndDate FROM @table WHERE id='CC' 
      union all 

      SELECT id, StartDate FROM @table WHERE id='DD' 
      union all 
      SELECT id, Dateadd(day,1,startdate) AS date FROM @table WHERE id='DD' AND Dateadd(day,1,startdate)<EndDate 
      union all 
      SELECT id, EndDate FROM @table WHERE id='DD' 
      union all 


      SELECT id, StartDate FROM @table WHERE id='EE' 
      union all 
      SELECT id, Dateadd(day,1,startdate) AS date FROM @table WHERE id='EE' AND Dateadd(day,1,startdate)<EndDate 
      union all 
      SELECT id, EndDate FROM @table WHERE id='EE' 
      union all 


      SELECT id, StartDate FROM @table WHERE id='FF' 
      union all 
      SELECT id, Dateadd(day,1,startdate) AS date FROM @table WHERE id='FF' AND Dateadd(day,1,startdate)<EndDate 
      union all 
      SELECT id, EndDate FROM @table WHERE id='FF' 

     Output: 
      id StartDate 
      AAA 2017-03-17 00:00:00.000 
      AAA 2017-03-18 00:00:00.000

首先，我创建了一个日历选项卡请根据您的MIN和MAX日期获取所有相关日期。然后我将它加入你的餐桌。

DECLARE @calendar AS TABLE ([Date] DATETIME) 

DECLARE @maxDate AS DATETIME = (SELECT CASE WHEN MAX(StartDate) > MAX(EndDate) 
             THEN MAX(StartDate) 
             ELSE MAX(EndDate) 
            END FROM @YourTable) 

DECLARE @minDate AS DATETIME = (SELECT CASE WHEN MIN(StartDate) < MIN(EndDate) 
             THEN MIN(StartDate) 
             ELSE MIN(EndDate) 
            END FROM @YourTable) 

WHILE (@minDate < @maxDate) 
BEGIN 
    INSERT INTO @calendar 
    VALUES (@minDate) 
    SET @minDate = DATEADD(DAY, 1, @minDate) 
END 

SELECT [Id], a.[Date] 
FROM (Select [Date] FROM @calendar) a 
LEFT JOIN @YourTable ON [Date] BETWEEN [StartDate] AND [EndDate] 
WHERE [Id] IS NOT NULL

CREATE TABLE t 
    (
     ID NVARCHAR(5) NOT NULL , 
     StartDate DATETIME NOT NULL , 
     EndDate DATETIME NOT NULL 
    ); 
    GO 

INSERT INTO dbo.t 
     (ID, StartDate, EndDate) 
VALUES (N'AAA', '2017-03-17 00:00:00.000', '2017-03-19 00:00:00.000'), 
     (N'BB', '2017-06-20 00:00:00.000', '2017-06-25 00:00:00.000'), 
     (N'CC', '2017-05-13 00:00:00.000', '2017-05-17 00:00:00.000'), 
     (N'DD', '2017-06-20 00:00:00.000', '2017-05-27 00:00:00.000'), 
     (N'EE', '2017-03-01 00:00:00.000', '2017-03-05 00:00:00.000'), 
     (N'FF', '2017-08-07 00:00:00.000', '2017-08-11 00:00:00.000'); 



WITH cte 
      AS (SELECT ID , 
         StartDate 
       FROM  dbo.t 
       UNION ALL 
       SELECT cte.ID , 
         DATEADD(DAY, 1, cte.StartDate) 
       FROM  cte 
         INNER JOIN dbo.t ON t.ID = cte.ID 
       WHERE cte.StartDate < EndDate 
      ) 
    SELECT cte.ID , 
      cte.StartDate 
    FROM cte 
    ORDER BY cte.ID , 
      cte.StartDate;

结果：
