我有以下sql：

select
CASE
          WHEN Count(*) > 1
              THEN 'Archiving task was executed succesfully!'
              ELSE 'Archiving task was not executed succesfully for day: ' || Days
          END CASE
from
(select substr(table_name,12,8) as Days from user_tables
where table_name like 'CDR_DETAIL_%' AND SubStr(table_name,12,8) IN ( SELECT * FROM tmp_archive_process_ict )
OR SubStr(table_name,12,8) IS null
order by 1 asc )
where rownum <= 7
GROUP BY Days
;

在 sql 工具中返回以下结果：

CASE
Archiving task was not executed succesfully for day: 20130819
Archiving task was executed succesfully!
Archiving task was not executed succesfully for day: 20130821
Archiving task was not executed succesfully for day: 20130820

在 shell 中使用 sqlplus，我试图将之前显示的 sql 的结果返回到一个文件中：

Unix外壳的一部分：

#Make oracle conneciton
-oracle connection sqlplus

SET PAGESIZE 0;
SET ECHO OFF;
SET SPACE 0;
SET FEEDBACK OFF;
SET HEADING OFF;

SPOOL /bmd/mail_check.txt

select
CASE
          WHEN Count(*) > 1
              THEN 'Archiving task was executed succesfully!'
              ELSE 'Archiving task was not executed succesfully for day: ' || Days
          END CASE
from
(select substr(table_name,12,8) as Days from user_tables
where table_name like 'CDR_DETAIL_%' AND SubStr(table_name,12,8) IN ( SELECT * FROM tmp_archive_process_ict )
OR SubStr(table_name,12,8) IS null
order by 1 asc )
where rownum <= 7
GROUP BY Days
;

SPOOL OFF;
EXIT;
EOF

该脚本有效，它会生成文件，但是当我检查文件（ cat /bmd/mail_check.txt ）时，它只显示：

Archiving task was executed succesfully!

我不明白为什么它不向我显示从 sql 选择到指定文件的其他结果。：

Archiving task was not executed succesfully for day: 20130819
Archiving task was not executed succesfully for day: 20130821
Archiving task was not executed succesfully for day: 20130820

我做错了什么？

先感谢您。

此致，
