Question

乍一看，这是我的查询

 INSERT INTO T2 
 SELECT T1.*,  T3.DATETIME, T3.STATEID
 FROM T1 WHERE T3.DATETIME BETWEEN '01-NOV-15' AND SYSDATE
 LEFT OUTER JOIN T3
 ON (T1.DOCID =  T3.DOCID);

T1 AND T2在列数方面几乎相同;只有T2有两列额外的（CREATIONDATE，STATEID）

T1的每一行都需要插入T2 +另外两列CREATIONDATE & STATEID中，这些列仅在T3中可用。 T1和'T3'都共享可用于加入它们的DOCID ...

仍有一些问题，非常感谢帮助。

Answer 1

WHERE子句位置的问题，必须在连接表列表之后：

INSERT INTO T2 
 SELECT T1.*,  T3.DATETIME, T3.STATEID
 FROM T1 
 LEFT OUTER JOIN T3
   ON (T1.DOCID =  T3.DOCID)
WHERE T3.DATETIME BETWEEN '01-NOV-15' AND SYSDATE;

Answer 2

您的语法不正确，在连接之后出现：

 INSERT INTO T2 
 SELECT T1.*,  T3.DATETIME, T3.STATEID
 FROM T1 
LEFT OUTER JOIN T3
ON (T1.DOCID =  T3.DOCID)
WHERE T3.DATETIME BETWEEN '01-NOV-15' AND SYSDATE

选择每一行并插入另一个表
