SQL Server 2000에서 실행되는 저장 프로 시저의 리버스 엔지니어링

Question

저장 프로 시저에 도움이 필요합니다. 데이터베이스와 관련하여 전적으로 멍청한 사람입니다. 나는 클라이언트가 고정시킬 필요가있는 프로그램을 가지고있다. 그것은 다른 개발자가 클라이언트가 연락을 취하지 못하게 만든 프로그램이다.

이 고객은이 프로그램을 소유하고 있으며 내가 좋아하는 모든 것을 할 수있는 완전한 권리를 부여 받았습니다. 문제는이 프로그램이 Crystal Reports를 사용하고 있으며 문제를 일으키는 특정 보고서가 StockAndSales입니다. 이 보고서는 저장 프로 시저에서 채워집니다. 그러나 문제는 데이터베이스의 모든 테이블을 비운 후에도 보고서에 여전히 존재하지 않아야하는 일부 필드가 표시된다는 것입니다.

프로그램은 .net 기반 응용 프로그램입니다.

그리고이 멍청한 게시물에 대해 유감스럽게 생각하지만 여기서는 새로운 것입니다.

P.S이 절차는 저에 의해 작성되지 않았습니다!

절차는 다음과 같습니다

당신은 필드 저장 프로 시저에서 반환되는 계산했다. 첫 번째 SELECT 문에서 모든 SUM() 필드

SUM(T1.O) AS O, SUM(T1.P1) AS P1,  SUM(T1.P2) AS P2, SUM(T1.P3) AS P3,.......
