Question

我有一个通过sql查询动态创建CTL文件的进程。我必须将文件名插入到oracle表中。我能够获得在查询上显示的文件名，但它一直拒绝它。 ctls只接受数字吗？因为如果我将它硬编码为数字，它将起作用。如果我硬编码到varchar，它将拒绝它。如何在加载时插入文件名？

           '  LEAD_TIME,' || chr (10) ||
       '  DELIVERY_TIME,' || chr (10) ||
       '  DELIVERY_NO,' || chr (10) ||
       '  FREQUENCY,' || chr (10) ||
       '  FREQUENCY_UNIT,' || chr (10) ||
       '  MODE_TYPE,' || chr (10) ||
       '  AUDIT_LOG_ID "' || MAX(audit_log_id) || '",' || chr (10) ||
       '  STAGING_STATUS_ID "1",' || chr (10) ||
       '  FILENAME "&fname",' || chr (10) ||
       '  LINENO SEQUENCE(1)' || chr (10) ||
       ' )' || chr (10)
   from   audit_log
   where filename_orig = '&fname';

spool off

这是运行sqlldr的输出。它正确显示文件名，但仍拒绝该条目。

  0 Rows not loaded because all fields were null.

Answer 1

您应该看到ORA-00984: column not allowed here之类的错误。 filenamexxx.csv被视为列名而不是值，因为它没有引用;您可以将其更改为：

FILENAME "'filenamexxx.csv'"

要做到这一点，你的查询已经转换了替换变量周围的单引号：

       '  FILENAME "''&fname"'',' || chr (10) ||

或者如果您愿意，可以选择引用机制：

       q'[  FILENAME "'&fname"',]' || chr (10) ||

在sqlldr
