我想创建一个物化视图,该视图应立即构建并在数据库中的每次提交时快速刷新以用于下面的内部连接查询。
示例查询格式:
CREATE MATERIALIZED VIEW test_view BUILD IMMEDIATE REFRESH FAST ON COMMIT AS
SELECT
INTTABLE.COLUMN1 AS "init col",
TABLE1.COLUMN1 AS "tab1 col",
TABLE2.COLUMN1 AS "tab2 col",
TABLE3.COLUMN1 AS "tab3 col"
FROM TABLE1
INNER JOIN TABLE3
ON TABLE1.COLUMN1 = TABLE3.COLUMN2
INNER JOIN TABLE2
ON TABLE2.COLUMN1 = TABLE3.COLUMN3
INNER JOIN INTTABLE
ON INTTABLE.COLUMN1 = TABLE2.COLUMN2;
错误消息:
Error at Command Line : 11 Column : 12
Error report -
SQL Error: ORA-12054: cannot set the ON COMMIT refresh attribute for the materialized view
12054. 00000 - "cannot set the ON COMMIT refresh attribute for the materialized view"
*Cause: The materialized view did not satisfy conditions for refresh at
commit time.
*Action: Specify only valid options.
