文档解释
ORA-32305: RepAPI materialized views with user-defined types are not supported
Cause: An attempt was made to create a RepAPI materialized view with user-defined types.
Action: Do not create a RepAPI materialized view with user-defined types.
ORA-32305:RepAPI材料视图不支持用户定义的类型
官方解释
ORA-32305表明,不支持使用RepAPI创建类型为用户定义类型的材料视图。错误代码最初出现在Oracle文档中,适用于Oracle 12c版本(12.1)。
常见案例
案例1:
示例查询,尝试在materialized view中使用用户定义的类型:
CREATE MATERIALIZED VIEW mvTest
as
SELECT t1.name, t2.user_defined_type_column
FROM table1 t1
INNER JOIN table2 t2
ON t1.id = t2.id
一般处理方法及步骤
1.为了避免ORA-32305导致的查询崩溃,当试图在Materialize视图中使用用户定义的类型时,应该避免使用,而是使用简单数据类型来替换。
2.可以通过使用以下代码在materialized view中模式替换用户定义的类型:
SELECT t1.name, CAST(t2.user_defined_type_column AS VARCHAR2(4000))
FROM table1 t1
INNER JOIN table2 t2
ON t1.id = t2.id
