T-SQL 중첩 된 서브 쿼리

Question

SQL 전문가가 아니며 CTE에서 준결승자이기도합니다.이 쿼리 문은 SQL Server가 2000이므로 기본 쿼리 내에서 다음 하위 쿼리의 결과 집합을 사용하여 코딩 할 수 있습니다.

declare @subcategoryConcatenate varchar(3999) 
set @subcategoryConcatenate = '' 

select @subcategoryConcatenate = @subcategoryConcatenate + pumpCategoryName + ',' FROM 
(SELECT 
      SCD.PUMPCATEGORYNAME, 
      SCD.ENGINECATEGORYNAME, 
      SCD.DETAILEDDESCRIPTION 
FROM PRTTICKHDR PHDR

LEFT JOIN SUBCATEGORYDESCRIPTION SCD ON PITM.ITEM = SCD.PUMPCATEGORY

Answer 1

SQL Server 2000은 열팽창 계수를 지원하지 않습니다.

select 
    .. stuff.. 
from 
    table1 t1 
    join table2 t2 on ...stuff... 
    join (
    select 
     ... 
    from 
     ... 
    where 
     ... 
) inline on ... stuff ... 
where 
    .... 

Answer 2

당신은 사용자 정의 함수가 필요합니다 : 귀하의 옵션은 많이 사용되는 경우 하위 쿼리에서 뷰를 만들거나 인라인 뷰를 수행하는 중에있다.
모양에서 각각 PRTTICKITEM은 개 이상일 수 있습니다.

CREATE FUNCTION GetPumpCategoriesByItem (@ItemID int) 

    RETURNS varchar (8000) 
AS 
BEGIN 
    DECLARE 
     @CategoryList  varchar (8000) 
    SET @CategoryList  = NULL -- MUST be null to avoid leading comma. 

    SELECT 
     @CategoryList  = COALESCE (@CategoryList + ', ', '') + SCD.PUMPCATEGORYNAME 
    FROM 
     SUBCATEGORYDESCRIPTION SCD 
    WHERE 
     SCD.PUMPCATEGORY = @ItemID 
    ORDER BY 
     SCD.PUMPCATEGORYNAME 

    RETURN @CategoryList 
END 

:
가 (. 문제는 더 나은 원하는 결과를 설명 할 필요가있다)

를하는 경우, 사용자의 UDF는 다음과 같이 보일 것입니다.

SELECT 
    PITM.ITEM, 
    dbo.GetPumpCategoriesByItem (PITM.ITEM), 
    ... ... 
FROM 
    ... ... 
INNER JOIN PRTTICKITEM PITM ON ... ... 
... ...
