PLS-00201: 必须声明标识符 'DBMS_SODA_ADMIN.DESCRIBE_COLLECTION'

Question

我正在使用 SODA for Java 从 oracle 12c 数据库中存储和检索文档。我正在关注这个 example.

我在执行代码后遇到异常。

Java代码

try(OracleConnection conn = (OracleConnection) DriverManager.getConnection(/*connection url*/)) {

        conn.setImplicitCachingEnabled(true);
        conn.setStatementCacheSize(50);

        OracleRDBMSClient cl = new OracleRDBMSClient();

        OracleDatabase db = cl.getDatabase(conn);

        db.admin().createCollection("MyFirstJSONCollection");

    } catch (SCExceptions | SQLException | OracleException e) {
        e.printStackTrace();
    }
}

此异常背后的原因是什么？

Answer 1

在您调用 db.admin().createCollection("MyFirstJSONCollection"); 时执行的代码中某处引用了数据库中不存在的名为 DBMS_SODA_ADMIN.DESCRIBE_COLLECTION 的对象。您应该检查模式 DBMS_SODA_ADMIN 是否存在，以及该模式中是否存在名为 DESCRIBE_COLLECTION 的对象。一种方法是执行查询，例如

SELECT *
  FROM DBA_USERS u
  WHERE u.USERNAME = 'DBMS_SODA_ADMIN'

SELECT *
  FROM DBA_OBJECTS o
  WHERE o.OWNER = 'DBMS_SODA_ADMIN' AND
        o.OBJECT_NAME = 'DESCRIBE_COLLECTION'

如果缺少任何一个，则表明 Soda 数据库组件的安装未执行或未成功完成。如果这些东西确实存在，则表明您的代码所连接的用户没有访问此对象所需的权限。

Answer 2

您是否将 SODA_APP 角色授予您在其下创建 collection 的用户？例如：

将 SODA_APP 授予 userNameHere；

如果您不这样做，就会发生您遇到的错误。
