느린 저장 프로 시저 - SQL Server

그래서 VB.NET 프로그램 내에서 사용할 저장 프로 시저를 만들었습니다. 이렇게하면 여러 테이블이 있는지 확인한 다음 관련 테이블을 만들고 데이터베이스 내의 다른 테이블을 사용하여 관련 테이블에 데이터를 삽입합니다. 원래는 저장 프로 시저가 잘 실행되었지만 최근에 변경된 사항이 있습니다. 실행 시간이 5 분 이상 걸리므로 시간 지연으로 인해 프로그램이 멈추는 문제가 있습니다. 따라서 저장 프로 시저를 실행하는 데 걸리는 시간을 줄여야합니다. 아래에 나는 오랜 시간이 걸리는 저장 프로 시저의 두 부분을 확인했습니다. 이들은 :느린 저장 프로 시저 - SQL Server

그냥 사람들이 그가 테이블이 실행하는 약 5 분 정도 복용과 함께 customers1 테이블이 약 30 초 정도 소요, 주요 문제를 일으키는 OrderLineHistory1 알려하지만 난 여전히이 함께 할 수있는 더 효율적입니다 –

SP가 천천히 실행되도록 변경 한 것은 무엇입니까? –

테이블에 가입하시는 열에 orderentry, order, pastorders가 색인되어 있습니까? –

전체 저장 프로 시저 주셔서 감사합니다. 정확한 비즈니스 요구 사항을 알지 못해 어떤 데이터에서도 테스트 할 수 없기 때문에 확신 할 수 없습니다. 그것을 시도하고 알려 :

set @tableID = 1 
set @lasttableID = (select max([id]) from Customers1) 
set @LineNumber = 1 
set @AccountNumber = (select AccountNumber from customers1 where id = @tableid) 

while @AccountNumber = (select AccountNumber 
         from Customers1 
         where id = @tableid) 
begin 
    update Customers1

고객 1 테이블 만위한 것입니까? :) 감사하고 도움을 주셔서 감사합니다 :) –

기본적으로 당신의 while 루프는 비슷한 패턴을 따릅니다. 모든 경우에 위 사항을 적용하고 SP의 속도를 높이면 알려주십시오. 또한 앞서 언급 한 다른 전략을 시도하십시오. 하지만 한 번에 하나씩 시도해보고 반복적 인 쿼리를 변경하여 패턴을 따라 테스트 해보십시오. 그렇지 않다면 앞에서 언급 한 것처럼 색인을 추가하십시오. 그렇지 않다면 SP를 나눕니다. 그 후에는 문제를 완전히 다르게 접근해야 할 수도 있습니다. –

또한 위의 코드를 사용하여 Customers1에 대한 이전 코드를 바꾼 후에는 어떤 이유로 느리게 실행됩니다./while 루프가 아닌 집합 기반 쿼리를 사용하여 수행 할 수 있다고 생각합니다. 어떻게 작성해야할지 모르겠습니다. –
