Oracle sqlcl格式在格式化文件时忽略自定义规则

Question

sqlcl在格式化缓冲区时似乎使用格式化规则，但在格式化文件时忽略它们。

我有一个输入文件（test.sql）和一小套格式化规则（format.xml）

[abayley@abayley1 ~]$ cat test.sql
SELECT * from DUAL;

[abayley@abayley1 ~]$ cat format.xml
<options>
<useTab>false</useTab>
<idCase>oracle.dbtools.app.Format.Case.lower</idCase>
<kwCase>oracle.dbtools.app.Format.Case.lower</kwCase>
</options>

显示应用于缓冲区而非文件的规则的sqlcl会话：

[abayley@abayley1 ~]$ sql username/[e-mail]:1521/dbname

设置SQLFORMATPATH也不起作用：

[abayley@abayley1 ~]$ export SQLFORMATPATH=format.xml
[abayley@abayley1 ~]$ sql username/[e-mail]:1521/dbname

将文件加载到缓冲区中，在那里格式化并保存回来可能是一种解决方法：

  format rules format.xml
  get test.sql nolist
  format buffer
  save test.sql replace
