无法在表上使用物化视图日志中的过滤器列

Question

I'm trying to create an aggregate Materialized View:

CREATE MATERIALIZED VIEW MV_LLATTRDATA_MAX_VERSIONS
    NOLOGGING
    BUILD IMMEDIATE 
    REFRESH FAST ON COMMIT
    ENABLE QUERY REWRITE
    AS 
        SELECT AD.DEFID, AD.ATTRID, MAX(AD.VERNUM) AS MAX_VERNUM, MIN(AD.DEFVERN) AS MAX_DEFVERN
        FROM   CSTST.MV_LLATTRDATA_PARTITIONED_TEST AD, DTREECORE DT
        WHERE AD.ID = DT.DATAID
        GROUP BY AD.DEFID, AD.ATTRID;

I don't understand the error. I have created a MV Log file for both the LLATTRDATA time and the DTREECORE table

CREATE MATERIALIZED VIEW LOG ON CSTST.DTREECORE (and LLATTR) WITH ROWID INCLUDING NEW VALUES; 

Error:

Error report - ORA-12033: cannot use filter columns from materialized view log on "CSTST"."DTREECORE" 12033. 0000 - "cannot use filter columns from materialized view log on \"%s\".\"%s\""

Cause: The materialized view log either did not have filter columns logged, or the timestamp associated with the filter columns was more recent than the last refresh time.

Action: A complete refresh is required before the next fast refresh. Add filter columns to the materialized view log, if required.

DTREECORE DDL:

CREATE MATERIALIZED VIEW LOG ON "CSTST"."DTREECORE"
 PCTFREE 10 PCTUSED 30 INITRANS 1 MAXTRANS 255 LOGGING
  STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1
  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
  TABLESPACE "CSPRD" 
  WITH ROWID INCLUDING NEW VALUES;

LLATTRCORE DDL:

  CREATE MATERIALIZED VIEW LOG ON "CSTST"."LLATTRDATA"
 PCTFREE 10 PCTUSED 30 INITRANS 1 MAXTRANS 255 LOGGING
  STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1
  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
  TABLESPACE "CSPRD" 
  WITH ROWID INCLUDING NEW VALUES;

我已经尝试添加 LLATTRCORE 查看日志以包含新值，但我遇到了权限问题

文档显示“对具有聚合的物化视图的快速刷新的限制”：

物化视图中的所有表都必须有物化视图日志，物化视图日志必须：

• 包含实体化视图中引用的表中的所有列。
• 使用 ROWID 和 INCLUDING NEW VALUES 指定。
• 如果预期表具有插入/直接加载、删除和更新的混合，请指定 SEQUENCE 子句。

您需要在日志中包含 MV 中使用的所有列，例如：

CREATE MATERIALIZED VIEW LOG ON MV_LLATTRDATA_PARTITIONED_TEST
WITH ROWID, SEQUENCE(ID, DEFID, ATTRID, VERNUM, DEFVERN) INCLUDING NEW VALUES;

CREATE MATERIALIZED VIEW LOG ON DTREECORE
WITH ROWID, SEQUENCE(DATAID) INCLUDING NEW VALUES;

然后你可以创建MV：

CREATE MATERIALIZED VIEW MV_LLATTRDATA_MAX_VERSIONS
    NOLOGGING
    BUILD IMMEDIATE 
    REFRESH FAST ON COMMIT
    ENABLE QUERY REWRITE
    AS 
        SELECT AD.DEFID, AD.ATTRID, MAX(AD.VERNUM) AS MAX_VERNUM, MIN(AD.DEFVERN) AS MAX_DEFVERN
        FROM   MV_LLATTRDATA_PARTITIONED_TEST AD, DTREECORE DT
        WHERE AD.ID = DT.DATAID
        GROUP BY AD.DEFID, AD.ATTRID;

Materialized view MV_LLATTRDATA_MAX_VERSIONS created.

不是最有用的错误消息...
