INFORMATION_SCHEMA.SCHEMATA_REPLICAS_BY_FAILOVER_RESERVATION 뷰에는 장애 조치 예약과 연결된 스키마 복제본에 관한 정보가 포함됩니다. INFORMATION_SCHEMA.SCHEMATA_REPLICAS_BY_FAILOVER_RESERVATION 뷰는 데이터 세트가 포함된 프로젝트로 범위가 지정되는 INFORMATION_SCHEMA.SCHEMATA_REPLICAS 뷰와 달리 장애 조치 예약의 프로젝트로 범위가 지정됩니다.
필요한 역할
INFORMATION_SCHEMA.SCHEMATA_REPLICAS_BY_FAILOVER_RESERVATION 뷰를 쿼리하는 데 필요한 권한을 얻으려면 관리자에게 프로젝트에 대한 BigQuery 리소스 뷰어(roles/bigquery.resourceViewer) IAM 역할을 부여해 달라고 요청하세요.
역할 부여에 대한 자세한 내용은 프로젝트, 폴더, 조직에 대한 액세스 관리를 참조하세요.
