커서를 사용하여 행의 각 열을 확인하고 각 일치에 대해 행을 반환하십시오.

Question

문자열 일치 조건에 따라 많은 테이블을 조인하도록 설계된 이전 개발자 저장 프로 시저를 수정 한 다음 조인 된 테이블을 검색하고 그 정보를 함께 반환합니다. 정보가 어떻게 매치되는지에 대한 설명과 함께

현재 프로 시저가 조인 된 테이블의 각 열을 살펴보고 일치하는 항목을 찾으면 결과 테이블에 새 행을 만들고 원본 테이블의 다음 열로 이동합니다. 문제는 행에 여러 개의 일치 항목이있는 경우입니다. 첫 번째 일치 항목이 생성되지 않은 후에는 아무 것도 없습니다.

----A---B---C---D---E---F---G---H---I--- 
|          | 
1.-------------------------------------| 
| N Y Y N N N N N N | 
2.-------------------------------------- 
| Y N N N N N N N N | 
3.-------------------------------------- 
| N Y N N Y Y N N N | 
---------------------------------------- 

테이블에 결과 :

내가 좋아하는 테이블을 필요로 각 열에 대한 별도의 루틴을 만드는 것보다 모든 일치하는 항목을 찾을 수있는보다 효율적인 방법이 있나요

----A---B---C---D---E---F---G---H---I--- 
|          | 
1.-------------------------------------- 
| found a match in row 1-B   | 
2.-------------------------------------- 
| found a match in row 1-C   | 
3.-------------------------------------- 
| found a match in row 2-A   | 
4.-------------------------------------- 
| found a match in row 3-B   | 
5.-------------------------------------- 
| found a match in row 3-E   | 
6.-------------------------------------- 
| found a match in row 3-F   | 
---------------------------------------- 

그 점검 할 필요가있다. 커서가 문제를 해결할 수 있다고 들었지만,이 쿼리는 이미 상당한 시간이 걸립니다. 그것은 여기에 도움이 경우

은 원래 절차 : 내가 거기에 더 효율적인 방법이 내가 큰 그림의 완전히 확실하지 않다 확신

Answer 1

-하지만 단순히 "나는이 질문에 대답 와 같은 표가 필요합니다 ... "여기에 빠르면 더러운 것 같습니다.

SELECT ID, 'Found a match in row ' + CAST(Id as varchar(8))+ '-A' FROM YOURTABLE WHERE A = 'Y' 
    UNION ALL SELECT ID, 'Found a match in row ' + CAST(Id as varchar(8))+ '-B' FROM YOURTABLE WHERE B = 'Y' 
    UNION ALL SELECT ID, 'Found a match in row ' + CAST(Id as varchar(8))+ '-C' FROM YOURTABLE WHERE C = 'Y' 

Answer 2

모든 논리가 저장 프로 시저에서 응용 프로그램으로 이동하기 시작했습니다. 저장 프로 시저는 단순히 테이블을 조인하고 몇 가지 간단한 필터를 수행했습니다. 그런 다음 응용 프로그램 (C#)을 사용하여 원하는 결과를 반환했습니다.
