결과 집합의 일부인 다음 OrganizationTeams 열의 셀의 첫 번째 사용자 두개의 결과를

가 NULL 반환. 이 사용자의 모든 셀에 대한

왜 반환하지 않습니다 3, 어떻게 그것을 않습니다 보장 할 수 있습니다 :이 왜,이 사용자가 3의 조직 팀을 할당 이해하지?

Answer 1

OrganizationalTeam 열은 DailyTaskHours> 작업> ProductTeamUser> 사용자를 통해 조인됩니다. 각 조인은 NULL 값이 될 수 있으므로 이러한 조인을 각각 점검하십시오. SELECT *으로 Query를 실행하고 WHERE을 사용하여 두 행 중 하나만 리턴하십시오.
