Присоединение к подзапросу с помощью оператора соединения

Question

Попытка применить подзапрос к таблице с целью его группировки.

Основной запрос

 SELECT soitem.fsono, fpartno, soitem.fcfromno, finumber
 FROM soitem 
 INNER JOIN somast on soitem.fsono = somast.fsono  
 WHERE somast.fsono='034313'  
 ORDER by soitem.fsono, soitem.finumber

Подзапрос

SELECT min(sq.finumber), sq.fcfromno 
FROM soitem sq 
WHERE sq.fsono='034313' 
GROUP BY sq.fcfromno   

min_finumber to further group my data set. This should appear as three rows">

Я хочу использовать min_finumber для дальнейшей группировки моего набора данных. Это должно появиться в виде трех строк. Я использовал свой оригинальный вопрос как способ включить подзапрос в мой общий код. Моя главная цель - успешно сгруппировать min_number

SELECT somast.fsono, 
somast.fcustno, 
somast.fcontact, 
somast.fcustpono,

ORDER BY somast.forderdate, somast.fsono, soitem.fcfromno

Answer 1

Я не использовал объединение или подзапрос. Я смог получить нужные мне результаты, добавив min(finumber) как min_fin к SELECT и ORDER BY

select soitem.fsono, 
somast.fcustno, 
somast.fcontact, 
somast.fcustpono, 
somast.fshipvia, 
somast.forderdate, 
somast.fduedate,
 soship.fccompany, 
 soship.fcphone, 
REPLACE(REPLACE(CONVERT(VARCHAR(MAX), soship.fmstreet), CHAR(13), '|'), CHAR(10), ' ') AS Street,
soship.fccity,
 soship.fcstate, 
 soship.fczip,
CAST(somast.fackmemo as CHAR(35)) as ShipCode,
CASE WHEN soitem.fcfromtype <> 'IFPKIT' THEN soitem.fpartno ELSE soitem.fcfromno END AS Item, 
CASE WHEN soitem.fcfromtype <> 'IFPKIT' THEN soitem.fquantity ELSE soitem.fquantity / soitem.fquoteqty END AS Qty, 
CASE WHEN soitem.fcfromtype <> 'IFPKIT' 
THEN CAST(soitem.fdesc as CHAR(35))
ELSE 'Store Set (Phantom)' END as Descr,
somast.fordername,
  somast.fcusrchr2,
somast.fcusrchr3,
somast.fcusrchr1, 
somast.festimator, 
soitem.fcfromno, 
soitem.fcfromtype, 

**min(finumber)as min_fin** 

from soitem INNER JOIN
 somast ON soitem.fsono = somast.fsono
 LEFT OUTER JOIN
 soship ON somast.fsono = soship.fcsono AND soship.fcenumber = ''

  where soitem.fsono='034313' 

group by soitem.fsono, CASE WHEN soitem.fcfromtype <> 'IFPKIT' THEN soitem.fpartno ELSE soitem.fcfromno END, 
soitem.fcfromno, soitem.fcfromtype,
somast.fcustno, 
somast.fcontact, 
somast.fcustpono, 
somast.fshipvia, 
somast.forderdate, 
somast.fduedate,
 soship.fccompany, 
 soship.fcphone,
 REPLACE(REPLACE(CONVERT(VARCHAR(MAX), soship.fmstreet), CHAR(13), '|'), CHAR(10), ' '),
soship.fccity,
 soship.fcstate, 
 soship.fczip,
 CAST(somast.fackmemo as CHAR(35)),
 CASE WHEN soitem.fcfromtype <> 'IFPKIT' THEN soitem.fquantity ELSE soitem.fquantity / soitem.fquoteqty END , 
CASE WHEN soitem.fcfromtype <> 'IFPKIT' 
THEN CAST(soitem.fdesc as CHAR(35))
ELSE 'Store Set (Phantom)' END, 
 somast.fordername,
  somast.fcusrchr2,
somast.fcusrchr3,
somast.fcusrchr1, 
somast.festimator

order by soitem.fsono, **min_fin**;

Answer 2

Поскольку вы используете SQL Server 2008 R2, у вас есть доступ к нужной вам функции окна. Попробуйте что-то вроде:

SQL Fiddle

Настройка схемы SQL Server 2017:

CREATE TABLE soitem 
(
     fsono INT, 
     fpartno INT,
     soitem INT, 
     finumber INT, 
     fcfromno INT
);

INSERT INTO soitem (fsono, fpartno, soitem, finumber, fcfromno)
VALUES (1, 1, 1, 1, 1), (1, 2, 2, 5, 1), 
       (2, 2, 2, 9, 2), (2, 2, 2, 2, 2),
       (3, 2, 2, 1, 9);

CREATE TABLE somast (fsono int) ;

INSERT INTO somast (fsono)
VALUES (1), (2);

Основной запрос:

SELECT 
    soitem.fsono,
    soitem.fpartno,
    soitem.fcfromno,
    soitem.finumber,
    /* THE BELOW PART IS YOUR "JOIN" */
    MIN(soitem.finumber) OVER (PARTITION BY soitem.fsono, soitem.fcfromno) AS min_finumber
FROM 
    soitem 
INNER JOIN 
    somast ON soitem.fsono = somast.fsono  
WHERE 
    somast.fsono = '1'
ORDER BY
    soitem.fsono, soitem.finumber

Результаты

| fsono | fpartno | fcfromno | finumber | min_finumber |
|-------|---------|----------|----------|--------------|
|     1 |       1 |        1 |        1 |            1 |
|     1 |       2 |        1 |        5 |            1 |

Ваш главный запрос:

SELECT soitem.fsono, fpartno, soitem.fcfromno, finumber
FROM soitem 
INNER JOIN somast on soitem.fsono = somast.fsono  
WHERE somast.fsono='1'  
ORDER by soitem.fsono, soitem.finumber

Результаты :

| fsono | fpartno | fcfromno | finumber |
|-------|---------|----------|----------|
|     1 |       1 |        1 |        1 |
|     1 |       2 |        1 |        5 |

Ваш подзапрос :

SELECT min(sq.finumber), sq.fcfromno 
FROM soitem sq 
WHERE sq.fsono='1' 
GROUP BY sq.fcfromno

Результаты

|   | fcfromno |
|---|----------|
| 1 |        1 |
