Google 시스템은 스키마가 100 개가 넘는 테이블을 가지고있어 꽤 큰 편입니다. 저장 프로 시저에서 처리하기로 결정한 비즈니스 요구 사항이있었습니다. 우리 응용 프로그램에서는 java도 있지만 저장 프로 시저를 사용하기로했습니다. 요구 사항을 충족시키기 위해 3 가지 기능을 만들었습니다. 이 함수는 카운트를 가져오고 레코드를 표시하기 위해 시작되는 SQL 쿼리의 일부입니다. 이제 우리는 60 초로 설정된 SQL timeout 연결을 설정했습니다. 40K 레코드에 대해이 쿼리를 실행하면 작업 시간이 초과되고 결과가 없습니다. 나는이 모든 3 가지 함수의 실제 구현을 여기에 붙여 넣고 있는데, 아래에는 생성 된 모든 함수를 사용하는 쿼리가 나와 있습니다.시간이 많이 걸리는 질문
아래의 쿼리에서 굵은 글씨체로 함수 호출을 표시했습니다.
나는이 구현을 조정하여 100K의 데이터를 처리 할 수있는 전문가의 조언을 구하고 있습니다. 우리는 Oracle 11gR1을 가지고 있습니다. 심지어이 구현은 Ajax 호출로 웹에서 액세스합니다.
다른 것이 필요한 경우 알려주십시오.
