Apex : 왼쪽 외부 조인 (하위 쿼리)을 사용하여 soql 명령 줄이는 방법?

아래는 내 스케줄 가능 정점 코드입니다. wkCSRCorderMaster__c (main), InstallationMaster__c, AddressMaster__c, ItemMaster__c 및 ItemAddonMaster__c 5 개의 테이블에서 데이터를 선택하고 싶습니다.Apex : 왼쪽 외부 조인 (하위 쿼리)을 사용하여 soql 명령 줄이는 방법?

기본적으로 이들 중 몇 가지 관계가 있지만이 경우에는 하위 쿼리를 사용하거나 '왼쪽 외부 조인'으로 쓰는 방법을 알지 못합니다. 따라서, 나는 당신이 볼 수있는 몇 가지 별개의 쿼리로 그들을 나눴다.

문제는 wkCSRCorderMaster에 한 번 (약 50-100 레코드)의 데이터가 많이 있지만, SOQL 명령에 대한 Apex 실행 감독자 제한은 동기 제한의 경우 100 배이고 비동기 제한의 경우 200 배에 불과합니다.

따라서 예상대로 제 코드가 작동하지 않습니다.

왼쪽 외부 조인 구문 또는 하위 쿼리를 사용하여 SOQL 명령을 줄이거 나 1 개로 결합 할 수 있는지 여부를 고려해보십시오.
