SQL 错误：ORA-32361

Question

当我在 Oracle Database 12c 第 2 版中创建实时实体化视图时，我收到 SQL 错误：ORA-32361。这是什么意思？

我的观点很简单，没有任何聚合。

CREATE MATERIALIZED VIEW example_t_mv
REFRESH FAST ON DEMAND
ENABLE QUERY REWRITE
ENABLE ON QUERY COMPUTATION
AS
SELECT et.some_value_1, et.some_value_2                         
FROM   example_t et WHERE et.some_value_2 < 10;

SQL 错误：ORA-32361：无法启用查询计算 物化视图

Answer 1

创建MVLog并尝试创建MV

CREATE MATERIALIZED VIEW LOG ON example_t
WITH ROWID, SEQUENCE(some_value_1, some_value_2)
INCLUDING NEW VALUES;
