如何动态更改行？

Question

我正试图找到一种动态更改最早日期字段日期的方法，因此如果TotalShipped = TotalOrdered，那么我想采用两个字段彼此不相等的最早日期。

这是数据当前的样子

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

这就是我想要的结果

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');

Answer 1

这是一种方法。

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

Answer 2

我最终使用了一个公用表表达式并加入了该表。

;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

)

select sorels.fsono, sorels.finumber, sorels.frelease,
