在 ODI 12c 中运行过程时出现 ORA-00933

Question

我正在创建一个一次性过程，以从现有源更新目标表中新添加的列。我创建了更新语句，在 SQLDeveloper 中对其进行了测试，并确认它完全符合我的要求。但是，当我将此代码添加到过程任务中时，它给了我一个 ORA-00933（SQL 命令未正确结束）错误。我附上了有问题的 sql 语句以及我选择的选项的一些解释。

已经完成：

• 新列添加到数据库表中
• 目标表模型已更新
• 映射已更新
• 验证初始加载在新列中的结果正确
• 已验证日志负载在新列中的结果正确

尝试过（没有区别）：

• 添加和删除分号 (;)
• 简化查询以删除“WHERE EXISTS”子句

目标命令：

UPDATE <%=odiRef.getSchemaName( "TARGET_SCHEMA", "D")%>.TARGET_TABLE target
   SET NEW_COLUMN = (SELECT source.EXISTING_COLUMN
                         FROM <%=odiRef.getSchemaName( "SOURCE_SCHEMA", "D")%>.SOURCE_TABLE source
                        WHERE target.SOURCE_KEY = source.PRIM_KEY)
 WHERE EXISTS (
    SELECT 1
      FROM <%=odiRef.getSchemaName( "SOURCE_SCHEMA", "D")%>.SOURCE_TABLE source
     WHERE target.SOURCE_KEY = source.PRIM_KEY)

目标命令设置：

技术：甲骨文
事务隔离：无变化
上下文：执行上下文
逻辑架构：TARGET_SCHEMA
事务：自动提交
提交：未定义

错误信息：

ODI-1217: Session POPULATE_TARGET_TABLE_NEW_FLAG (123456789) fails with return code 933.

所以问题不在于完全代码本身，而是我没有在代码更改之间重新生成我的场景这一事实。我自己的错，我在 ODI 中主要是自学成才，没想到要尝试...

感谢 Marmite Bomber，您的评论让我更深入地研究了这个问题，并意识到“生成”的代码在我做出任何更改时都没有更新。

Answer 2

由于发布的代码中存在无效字符，我希望这些无效字符应该被传递给 Oracle 执行的代码中的目标表所有者和 table_name 替换，因此我怀疑生成的 SQL 不正确。无论如何，您可以捕获传递给 Oracle 的代码吗？
