不同 oracle 模式的物化视图导致 ORA-1208答案

【问题标题】：Materialized view for different oracle schema results in ORA-1208不同 oracle 模式的物化视图导致 ORA-1208
【发布时间】：2014-10-11 17:11:00
【问题描述】：

我想在提交时创建物化 oracle 视图，指向同一数据库实例中不同模式的表。

模式（BATCH）：

CREATE TABLE "BATCH"."BATCH_CONFIG" 
   (    "KEY" VARCHAR2(100 BYTE), 
    "VALUE" VARCHAR2(4000 BYTE), 
    "COMMENTS" VARCHAR2(4000 BYTE), 
    "UPDATED_BY" VARCHAR2(25 BYTE), 
    "UPDATED" TIMESTAMP (6), 
     CONSTRAINT "PK_BATCH_CONFIG" PRIMARY KEY ("KEY")
   );

create materialized view log on batch_config;
grant all on batch_config to profile;

架构（配置文件）：

create materialized view mv_batch_config REFRESH FAST ON COMMIT
        as select * from BATCH.batch_config;

出错了：

SQL Error: ORA-12018: following error encountered during code generation for "PROFILE"."MV_BATCH_CONFIG"
ORA-00942: table or view does not exist
12018. 0000 -  "following error encountered during code generation for \"%s\".\"%s\""
*Cause:    The refresh operations for the indicated materialized view could
           not be regenerated due to errors.
*Action:   Correct the problem indicated in the following error messages and
           repeat the operation.

有什么问题？我可以通过（从配置文件模式）select * from BATCH.batch_config 来查看查询

【问题讨论】：

你的 batch.batch_config 表上有主键吗？
是的。 CREATE TABLE "BATCH"."BATCH_CONFIG" ("KEY" VARCHAR2(100 BYTE), "VALUE" VARCHAR2(4000 BYTE), "COMMENTS" VARCHAR2(4000 BYTE), "UPDATED_BY" VARCHAR2(25 BYTE), "UPDATED" TIMESTAMP (6)、CONSTRAINT "PK_BATCH_CONFIG" PRIMARY KEY("KEY"))

【解决方案1】：

好的，我终于找到了解决方案。

我还必须在 mview 日志上授予选择权限。

GRANT SELECT ON MLOG$_BATCH_CONFIG TO PROFILE;
