Как динамически изменить строку?

Question

Я пытаюсь найти способ динамического изменения дат в поле «Самая ранняя дата», поэтому, если TotalShipped = TotalOrdered , тогда я хочу взять самую раннюю дату, когда два поля не равны друг другу.

Это пример того, как данные в настоящее время выглядят

CREATE TABLE mytable (
  fsono INT
  , NAME VARCHAR(30)    
  , TS int
  , [TO] int   
  , [Date] date  
);

INSERT INTO mytable (fsono, NAME, TS, [TO], [Date])
  VALUES
    (1,'039069',1,1,'2019-3-19')
    , (2,'039069',1,1,'2019-3-19')
    , (3,'039069',1,0,'2019-3-20')
    , (4,'039069',1,0,'2019-3-21');

SELECT 
  sorels.fsono,
  sorels.finumber,
  sorels.frelease,
  fshipbook+fshipbuy+fshipmake as totalshipped,
  fjoqty + fbook + fbqty as totalordered,
  sorels.fduedate
FROM m2mdata35.dbo.sorels   
INNER JOIN somast on sorels.fsono=somast.fsono   
INNER JOIN soitem on sorels.fsono=soitem.fsono AND sorels.finumber=soitem.finumber   
LEFT JOIN inmastx on soitem.fpartno=inmastx.fpartno and soitem.fpartrev=inmastx.frev  
LEFT JOIN jomast on sorels.fstatus=jomast.fjobno 
LEFT JOIN slcdpmx on somast.fcustno=slcdpmx.fcustno  
LEFT JOIN syphon ON somast.fcontact=syphon.fcontact AND somast.fcustno=syphon.fcsourceid 
WHERE LEFT(somast.fstatus,1)<>'C' and fsocoord<>'IFP' and fsocoord<>'711' 
and somast.fsono='039069' 
Order By sorels.fsono, sorels.fduedate, sorels.finumber, sorels.frelease

Вот как бы я хотел, чтобы результаты выглядели как

CREATE TABLE myresults (
  fsono INT 
  , NAME VARCHAR(30)
  , TS int  
  , [TO] int   
  , [Date] date  
  , Earliest_Date date 
);

INSERT INTO myresults (fsono, NAME, TS, [TO], [Date], Earliest_Date)
  VALUES
    (1,'039069',1,1,'2019-3-19','2019-3-20')
    , (2,'039069',1,1,'2019-3-19','2019-3-20')
    , (3,'039069',1,0,'2019-3-20','2019-3-20')
    , (4,'039069',1,0,'2019-3-21','2019-3-20');

В итоге я использовал общее табличное выражение и присоединился к этой таблице.

;with cte1 as (
SELECT Distinct 
sorels.fsono,
min(sorels.fduedate ) Over(Partition by sorels.fsono, Case when fshipbook+fshipbuy+fshipmake <> sorels.fjoqty + sorels.fbook + sorels.fbqty then 1 else 0 end ) as EarliestDate

Вот один из способов сделать это.

Select  AllData.*,
        earliest.mismatch
from    #mytable    AllData
    left join
        (Select NAME, 
                min(date) mismatch
        from    #mytable
        where   [ts] <> [TO]
        group by
                NAME) earliest         on AllData.Name = earliest.Name
