如何从缺少count的另一个表中显示缺少的行值？

Question

我有一个表星期日值与星期日和SundayTimes来自另一个表，其中有一个where子句，只包括weekdat星期日。星期日是在星期日时间登录工作的医院成员的ID的计数，这是与00:00至23:00相关的军事时间列表。由于没有记录任何小时02:00，该表显示为

00:00  3 
01:00  4 
03:00  2 

我怎么会占到缺少时间，所以它显示的格式

02:00  0 

在列表中的正确顺序。我必须能够考虑所有可能的缺失时间，因为这些参数可能与日期不同并且与日期不同。

结果星期日： enter image description here

这里是我到目前为止所。

Answer 1

在上次查询之前，您可以添加此步骤：

DECLARE @i INT; 
DECLARE @time VARCHAR(5); 
SET @i=0; 
WHILE @i < 24 
BEGIN 
    SET @time = RIGHT('00'+CAST(@i AS VARCHAR(2)),2)+':00' 
    INSERT INTO @Sundays 
    SELECT 0, @time 
    SET @i = @i + 1; 
END 

对不起，如果出现错误，我无法在发布前测试。

解释：为了以防万一，我们将所有小时添加为0作为计数。

新的答案：

create table #empty_hours (Days BIGINT, Times varchar(5)) 
DECLARE @i INT; 
DECLARE @time VARCHAR(5); 
SET @i=0; 
WHILE @i < 24 
BEGIN 
    SET @time = RIGHT('00'+CAST(@i AS VARCHAR(2)),2)+':00' 
    INSERT INTO #empty_hours 
    SELECT 0, @time 
    SET @i = @i + 1; 
END 

INSERT INTO #Sundays SELECT * from #empty_hours ; 
INSERT INTO #Mondays SELECT * from #empty_hours ; 
INSERT INTO #Tuesdays SELECT * from #empty_hours ; 
INSERT INTO #Wednesdays SELECT * from #empty_hours ; 
INSERT INTO #Thursdays SELECT * from #empty_hours ; 
INSERT INTO #Fridays SELECT * from #empty_hours ; 
INSERT INTO #Saturdays SELECT * from #empty_hours ; 

新的解释：

我们创建一个#empty_hours临时表;我们使用0作为帐户填写所​​有小时（结果没有发生）。然后在所有表格中插入这些“空”值，以防缺失一些小时。

我认为这是你需要的。你不需要每天都使用单独的表格。

CREATE TABLE #TestingTesting123 (Id bigint, WkDay varchar(30), Admittime varchar(5), primary key(Id)) 
    INSERT INTO #TestingTesting123 (Id, WkDay, Admittime) 
     SELECT r.Id, 
      datename(dw, r.AdmitDate) As WkDay, 
      CASE 
       WHEN r.Admittime = ':' 
        THEN '00:00' 
       ELSE  
        isnull(LEFT(r.Admittime,2),0) + ':00 ' 
       END as AdmitTime 
     FROM registrations r 
     WHERE r.AdmitDate between @fromdate AND @todate      
      AND r.registrationtypeid = @RegistrationTypeId 
     ORDER BY AdmitTime Asc 

-- table with all hours in day 
declare @Hours table 
(
    T_Hour varchar(5) 
) 

declare @i smallint 
set @i = 0 
while @i < 24 
begin 
    insert into @Hours 
    select right('00' + cast(@i as varchar), 2) + ':00' 

    set @i = @i + 1 
end 

-- result query 
select 
    T_Hour, 
    ISNULL(SUM(case when WkDay = 'Sunday' then CountValue else 0 end), 0) as Sunday, 
    ISNULL(SUM(case when WkDay = 'Monday' then CountValue else 0 end), 0) as Monday, 
    ISNULL(SUM(case when WkDay = 'Tuesday' then CountValue else 0 end), 0) as Tuesday, 
    ISNULL(SUM(case when WkDay = 'Wednesday' then CountValue else 0 end), 0) as Wednesday, 
    ISNULL(SUM(case when WkDay = 'Thursday' then CountValue else 0 end), 0) as Thursday, 
    ISNULL(SUM(case when WkDay = 'Friday' then CountValue else 0 end), 0) as Friday, 
    ISNULL(SUM(case when WkDay = 'Saturday' then CountValue else 0 end), 0) as Saturday 
from @Hours 
    left outer join 
    (
     select WkDay, Admittime, count(Id) as CountValue     
     from #TestingTesting123 
     group by WkDay, Admittime 
    ) T 
    on T_Hour = Admittime 
group by T_Hour
