SQL-Syntax zu verwenden

Question

Ich brauche Hilfe, wie werde ich die Probe ausgeben, weil ich weiß, dass es nicht möglich ist.

SAMPLE TABLE

Answer 1

Könnten Sie das versuchen?

DECLARE @employee_dtrlogs TABLE (ID INT, empuser VARCHAR(20), empcode VARCHAR(20), dtDateTime DATETIME, dtStatus INT) 
INSERT INTO @employee_dtrlogs 
VALUES 
(1,'USER1','USR1','2017-7-1 9:00:00',1), 
(2,'USER1','USR1','2017-7-1 18:00:00',2), 
(3,'USER1','USR1','2017-7-4 9:00:00',1), 
(4,'USER1','USR1','2017-7-4 18:00:00',2) 

DECLARE @employee_calendar TABLE(CalendarDate DATE) 

INSERT INTO @employee_calendar VALUES 
('2017-7-1'), 
('2017-7-2'), 
('2017-7-3'), 
('2017-7-4'), 
('2017-7-5') 


;WITH UserAndStatus AS (
    SELECT 
     DISTINCT empuser, empcode, dtStatus 
    FROM @employee_dtrlogs 
) 
SELECT 
    ROW_NUMBER() OVER(ORDER BY C.CalendarDate , U.dtStatus) ID, 
    U.empuser [USER], 
    U.empcode EMPCODE, 
    C.CalendarDate [DATE], 
    CONVERT(VARCHAR, L.dtDateTime, 14) TIME, 
    CASE L.dtStatus WHEN 1 THEN 'TIME-IN' WHEN 2 THEN 'TIME-OUT' END STATUS 
FROM @employee_calendar C 
    CROSS JOIN UserAndStatus U 
    LEFT JOIN @employee_dtrlogs L ON 
      L.empcode = U.empcode 
      AND L.dtStatus = U.dtStatus 
      AND C.CalendarDate = CAST(L.dtDateTime AS date) 

Ergebnis

ID     USER     EMPCODE    DATE  TIME       STATUS 
-------------------- -------------------- -------------------- ---------- ------------------------------ -------- 
1     USER1    USR1     2017-07-01 09:00:00:000     TIME-IN 
2     USER1    USR1     2017-07-01 18:00:00:000     TIME-OUT 
3     USER1    USR1     2017-07-02 NULL       NULL 
4     USER1    USR1     2017-07-02 NULL       NULL 
5     USER1    USR1     2017-07-03 NULL       NULL 
6     USER1    USR1     2017-07-03 NULL       NULL 
7     USER1    USR1     2017-07-04 09:00:00:000     TIME-IN 
8     USER1    USR1     2017-07-04 18:00:00:000     TIME-OUT 
9     USER1    USR1     2017-07-05 NULL       NULL 
10     USER1    USR1     2017-07-05 NULL       NULL 

Answer 2

Dies ist ein Weg, um Ihre Ausgabe zu erreichen

SELECT l.ID, l."DATE", l."USER", c.CaledarDate, l.STATUS 
    FROM employee_dtrlogs l 
     RIGHT JOIN employee_calendar c 
     ON c.CaledarDate=l.DATE AND l.STATUS='TIME-IN' 
UNION ALL 
    SELECT l.ID, l."DATE", l."USER", c.CaledarDate, l.STATUS 
    FROM employee_dtrlogs l 
     RIGHT JOIN employee_calendar c 
     ON c.CaledarDate=l.DATE AND l.STATUS='TIME-OUT' 
ORDER BY c.CaledarDate, l.ID

Answer 3

Versuchen Sie folgendes:

select distinct edr.ID,c.[User], c.[Date], edr.[Time], c.[Status] from employee_dtrlogs edr RIGHT JOIN 
(
select * from (select distinct [User], [Status] FROM employee_dtrlogs)a 
CROSS JOIN (SELECT [Date] FROM employee_calendar) b 

)c 
on edr.[USER] = c.[User] AND edr.[Date] = c.[Date] AND edr.[Status] = c.[Status] 
ORDER BY c.[Date] 

Nur eine Anmerkung Ich habe [Datum] als Spaltenname anstelle von [CalendarDate] verwendet. Sie können es ersetzen und überprüfen Sie die Ausgabe
