UNION et MIN/MAX avec regroupement et demande de date impaire

Question

Ceci est une nouvelle version de ma question, car elle semble confuse. Pardon. Je l'ai compris. Voir le code si vous êtes intéressé. Les notes à résoudre sont là. Merci de votre aide!

Je l'ai eu à travailler jusqu'à présent, mais l'OriginaionL (L est pour Little et B est pour Big) n'est pas correct. Il prend la bonne date mais pas l'origine.

CREATE TABLE MyTable 
(
    LoadTagID     INT, 
    EnteredDateTime   datetime, 
    JobNumber     VARCHAR(50), 
    Origination    VARCHAR(50) 
) 

INSERT INTO MyTable VALUES 
(1, '2015-02-09 00:00:00.00', 11111, 'Here') 
,(2, '2015-02-09 00:00:00.00', 22222, 'There') 
,(3, '2016-03-09 00:00:00.00', 11111, 'Outside') 
,(4, '2016-08-09 00:00:00.00', 12578, 'Anywhere') 
,(252, '2017-06-29 00:00:00.00', 12345, 'Here') 
,(253, '2017-08-01 00:00:00.00', 99999, 'There') 
,(254, '2017-08-04 00:00:00.00', 12345, 'Outside')

--Select * From MyTable 

CREATE TABLE #LTTB1   --MAX 
( 
    LoadTagID varchar(50), 
    JobNumber varchar(50), 
    EnteredDateTime varchar(50), 
    Origination varchar(50) 
) 
CREATE TABLE #LTTB2   --MIN 
(
    LoadTagID varchar(50), 
    JobNumber varchar(50), 
    EnteredDateTime varchar(50),   
    Origination varchar(50) 
) 
CREATE TABLE #LTTB3 
(
    LoadTagIDL varchar(50), 
    JobNumberL varchar(50), 
    EnteredDateTimeL 
    varchar(50), 
    OriginationL varchar(50) 
    , LoadTagID varchar(50), 
    JobNumber varchar(50), 
    EnteredDateTime varchar(50), 
    Origination varchar(50) 
) 


INSERT INTO #LTTB1 
SELECT 
    MAX(LoadTagID) AS LoadTagID, 
    JobNumber, 
    MAX(EnteredDateTime) AS EnteredDateTime, 
    MAX(Origination) AS Origination 
FROM MyTable 
WHERE CONVERT (Date, EnteredDateTime) >= CONVERT (Date, GETDATE()-10) --Gets the last 10 days. 
GROUP BY JobNumber ORDER BY JobNumber 

INSERT INTO #LTTB2 
SELECT MIN(LoadTagID) AS LoadTagIDL, 
    JobNumber AS JobNumberL, 
    MIN(EnteredDateTime) AS EnteredDateTimeL, 
    MAX(Origination) AS OriginationL --MAX! This needed to be max!! Why? 
FROM MyTable 
Where CONVERT (Date, EnteredDateTime) >= CONVERT (Date, GETDATE()-60) --Goes further back in case one is a long. 
GROUP BY JobNumber ORDER BY JobNumber 

INSERT INTO #LTTB3 
SELECT L.LoadTagID AS LoadTagIDL 
    , L.JobNumber AS JobNumberL 
    , L.EnteredDateTime AS EnteredDateTimeL 
    , L.Origination AS OriginationL 
    , B.LoadTagID, B.JobNumber, B.EnteredDateTime, B.Origination 
FROM #LTTB1 B --MAX 
INNER JOIN #LTTB2 L ON B.JobNumber = L.JobNumber 

Select * From #LTTB3 

Donc, pour numéro_travail 6/29 est correcte 12345, mais il devrait être « ici » et non « Partout:

Pour 99999 tout est correct, mais pour 8/1 il devrait être « là » et nulle part. cela semble être la valeur moyenne dans l'ensemble. Je suis tellement confus.

est-ce que quelqu'un sait pourquoi il est saisissant cette valeur? Merci.

Answer 1

SELECT * 
FROM mytable 
WHERE LoadTagID=(SELECT MIN(LoadTagID) 
       FROM mytable) 
OR LoadTagID=(SELECT MAX(LoadTagID) 
       FROM mytable);

Answer 2

CREATE TABLE MyTable 
(
    LoadTagID  INT, 
    Date   Date, 
    Job   INT, 
    Origination VARCHAR(20) 
) 

INSERT INTO MyTable 
VALUES(
     252, '6/29/17', 12345, 'Here') 
    ,(253, '8/1/17', 99999, 'There') 
    ,(254, '8/4/17', 12345, 'Outside') 
    ,(255, '8/8/17', 12345, 'Anywhere') 

--SELECT * FROM MyTable 

SELECT * INTO #Table1 
FROM MyTable 
WHERE LoadTagID IN (SELECT MIN(LoadTagID) 
        FROM MyTable) 

SELECT * INTO #Table2 
FROM MyTable 
WHERE LoadTagID IN (SELECT MAX(LoadTagID) 
        FROM MyTable) 

SELECT * INTO #T3 
FROM (SELECT * FROM #Table1 T1 
     UNION ALL 
     SELECT * FROM #Table2 T2 
    ) A 

SELECT #T3.Date, 
     #T3.Job, 
     #T3.LoadTagID, 
     #T3.Origination 
FROM #T3 
LEFT JOIN #Table1 T1 
ON T1.Job=#T3.Job 
WHERE T1.Job IS NOT NULL 

Answer 3

INSERT INTO #LTTB1 
SELECT 
    MAX(LoadTagID) AS LoadTagID, 
    JobNumber, 
    MAX(EnteredDateTime) AS EnteredDateTime, 
    MAX(Origination) AS Origination 
FROM MyTable 
WHERE CONVERT (Date, EnteredDateTime) >= CONVERT (Date, GETDATE()-10) --Gets the last 10 days. 
GROUP BY JobNumber ORDER BY JobNumber 

INSERT INTO #LTTB2 
select LoadTagID 
,JobNumber 
,EnteredDateTime 
,Origination from (
select *, ROW_NUMBER() Over(partition by jobnumber order by EnteredDateTime) l 
from MyTable 
Where CONVERT (Date, EnteredDateTime) >= CONVERT (Date, GETDATE()-60) 
)lk 
where lk.l=1 

INSERT INTO #LTTB3 
SELECT L.LoadTagID AS LoadTagIDL 
    , L.JobNumber AS JobNumberL 
    , L.EnteredDateTime AS EnteredDateTimeL 
    , L.Origination AS OriginationL 
    , B.LoadTagID, B.JobNumber, B.EnteredDateTime, B.Origination 
FROM #LTTB1 B --MAX 
INNER JOIN #LTTB2 L ON B.JobNumber = L.JobNumber 


Select * From MyTable 
Select * From #LTTB3
