sql - 忽略选择查询中的列但需要用作连接条件

Question

在这里我有这个过程，我需要将数据插入目标表 4.在所有这些子查询中，我需要根据 scan_id 加入，但同时我不应该在选择查询中使用 scan_id 分组结果集合被分割成更多的粒度。即使我尝试使用“按子句分区”，它也提供了更多的记录。我们如何避免 scan_id 列，应该使用与连接条件相同的列。目标表 4

SOA_SECTOR                           VARCHAR2(100 CHAR) 
SOA_REGION                           VARCHAR2(100 CHAR) 
PROJECT                     NOT NULL VARCHAR2(256 CHAR) 
SOLUTION                             VARCHAR2(256 CHAR) 
FIRST_SCAN_ISSUE_CNT        NOT NULL NUMBER(10)         
FIRST_FILES_WITH_ISSUES_CNT NOT NULL NUMBER(10)         
FIRST_SCAN_FILE_CNT         NOT NULL NUMBER(10)         
TOTAL_FILES_FOR_PROJECT_CNT NOT NULL NUMBER(10)         
LAST_SCAN_ISSUE_CNT         NOT NULL NUMBER(10)         
LAST_FILES_WITH_ISSUES_CNT  NOT NULL NUMBER(10)         
LAST_SCAN_FILE_CNT          NOT NULL NUMBER(10)         
PRIOR_SCAN_ISSUE_CNT        NOT NULL NUMBER(10)         
PRIOR_FILE_WITH_ISSUES_CNT  NOT NULL NUMBER(10)         
PRIOR_SCAN_FILE_CNT         NOT NULL NUMBER(10)
