动态假脱机到文件名

Question

我想每周在 sqlplus 或 SQLCL 中提取相同的查询，可能会在 Windows 服务器上安排任务，在 csv 文件中使用帐户代码和日期的名称进行假脱机。 我编写了以下脚本，它可以工作，但我有两个问题。

SET ECHO OFF
SET FEEDBACK OFF
SET VERIFY OFF
COL VPATH NEW_VALUE NEW_VPATH;
COL PRESIDIO NEW_VALUE NEW_PRESIDIO;
COL SEPARATORE NEW_VALUE NEW_SEPARATORE;
COL DATA NEW_VALUE NEW_DATA;
COL EXT NEW_VALUE NEW_EXT;
SET SQLFORMAT CSV;
SELECT 'C:\Shared_Folder\' VPATH, 'AO_GALLARATE' PRESIDIO,'_' SEPARATORE, TO_CHAR(CURRENT_DATE) DATA,'.CSV' EXT FROM DUAL;
SET FEEDBACK ON;
SET TERMOUT OFF;
SPOOL "&NEW_VPATH&NEW_PRESIDIO&NEW_SEPARATORE&NEW_DATA&NEW_EXT";
SELECT /*CSV*/ SERIAL_NUMBER, DNS_HOST_NAME, IP_ADDRESS, MODEL_NAME, TOTAL_PAGE_COUNT - COLOR_PAGE_COUNT, COLOR_PAGE_COUNT, TRUNC(LAST_DATA_COLLECTION) FROM DEVICE WHERE ACCOUNT_CODE = '&NEW_PRESIDIO' AND model_name LIKE '%MS410%';
ORDER BY SERIAL_NUMBER ASC;
SPOOL OFF;

1. 我收到一个提示，要求为所有 new_vpath、new_presidio.. 至少第一次输入一个值。如果我删除这部分，我会在应该开始假脱机时收到请求
2. 如果我使用pl/sql，我可以成功设置变量，所以没有提示出现，但是假脱机和查询不起作用。实际上假脱机表示非法文件名和查询不适用于查询中缺少“account_code”字符串。

我在哪里做错了什么？

Answer 1

可能什么都没有。这与@ruudvan 所说的重复有点不同。您应该能够按照您的方式在 spool 命令上使用替换。

这是早期版本中的错误。在最新版本的 SQLcl 中，我已经尝试过了，似乎效果很好。

(~/qa) $cat subnew.sql
SET ECHO  OFF
SET FEEDBACK OFF
SET VERIFY OFF
COL VPATH NEW_VALUE NEW_VPATH;
COL PRESIDIO NEW_VALUE NEW_PRESIDIO;
COL SEPARATORE NEW_VALUE NEW_SEPARATORE;
COL DATA NEW_VALUE NEW_DATA;
COL EXT NEW_VALUE NEW_EXT;
COL USER NEW_VALUE NEW_USER;
SET SQLFORMAT CSV;
SELECT './' VPATH, 'AO_GALLARATE' PRESIDIO,'_' SEPARATORE, TO_CHAR(CURRENT_DATE) DATA,
       '.CSV' EXT , USER FROM DUAL;
SET FEEDBACK OFF;
SET TERMOUT OFF;
SPOOL "&NEW_VPATH&NEW_PRESIDIO&NEW_SEPARATORE&NEW_DATA&NEW_EXT";
select /* csv */ * from substitution
where upper(name) = '&NEW_USER';
SPOOL OFF;
exit
