Question

我正在尝试编写一个sqlldr.ctl文件，以便在条款中将导入的记录限制为与当前Schema名称的一部分匹配的记录。

我的代码（ NOT 工作）是：

 LOAD DATA
 TRUNCATE INTO TABLE TMP_PRIM_ACCTS
 when REGION_NUM = substr(user,-3,3)
 Fields terminated by "|" Optionally enclosed by '"'
 Trailing NULLCOLS
  ( PORTFOLIO_ACCT,
    PRIMARY_ACCT_ID NULLIF (PRIMARY_ASSET_ID="NULL"),
    REGION_NUM    NULLIF (PARTITION_NUM="NULL")
  )

sqlldr返回：

 SQL*Loader-350: Syntax error at line 3.
 Expecting quoted string or hex identifier, found "substr".
 when PARTITION_NUM = substr(user,-3,3)

我不能在“user”周围添加单引号，因为它将其转换为文字字符串“user”。任何人都可以解释我如何在这个WHEN条款中引用“活跃”用户？

谢谢！

你可以试试这样的东西吗？（现在我无法使用SQLLDR进行测试，但这是我用来更改值的语法）：

Answer 2

它看起来不像你。 The documentation仅显示固定值：

尝试在when该子句中使用表达式（或在nullif中;我想我是否会尝试查看是否可能导致基于空PK值的拒绝）您只看到日志中的文字值：

Table TMP_PRIM_ACCTS, loaded when REGION_NUM = 0X73756273747228757365722c2d332c3329(character 'substr(user,-3,3)')

当你说你不能引用user时，这就是你所提到的那种，但你无论如何都要完整。使用:user也不起作用，冒号只被视为另一个字符，它不会尝试找到名为user的列。

最简单的方法可能是预处理数据文件并删除任何与模式不匹配的行（例如通过正则表达式）。如果您使用外部表而不是SQL * Loader，那实际上会更容易一些。

或者，生成您的控制文件，并根据您要连接的用户嵌入正确的文字值。
