在尝试使用Oracle 12c中的聚合快速刷新物化视图时，我收到错误ORA-01792“表或视图中的最大列数为1000” . 但是，视图的列数少于1000;甚至将基表的列添加（这是另一个快速物化视图），我没有达到1000.我已经根据Oracle手册对聚合物的物化视图进行了所有限制，我几乎可以肯定我我没有违反任何一个 . 不确定是否可以在另一个快速MV上创建快速MV .
该脚本如下：
CREATE MATERIALIZED VIEW MVW_USER_PAYMENTS
TABLESPACE TESTING
NOCACHE
NOLOGGING
NOCOMPRESS
NOPARALLEL
BUILD IMMEDIATE
USING INDEX
TABLESPACE TESTING_IDX
REFRESH FAST
START WITH TO_DATE('30-jul-2015 23:00:00','dd-mon-yyyy hh24:mi:ss')
NEXT SYSDATE+1/24
WITH PRIMARY KEY
AS
SELECT
ID,
YEAR,
NAME,
-- Summarised fields
SUM(TOTAL_AMOUNT) AS TOTAL_AMOUNT, COUNT(TOTAL_AMOUNT) AS CNT_TOTAL_AMOUNT,
SUM(VAL_INTEREST) AS VAL_INTEREST, COUNT(VAL_INTEREST) AS CNT_VAL_INTEREST,
.
.
.
(more rows)
.
COUNT(*) AS TOTAL_RECORDS
FROM MVW_USER_PAYMENTS_ORIGINAL
GROUP BY
ID,
YEAR,
NAME;
任何提示都非常感谢！
