sqlplus 输出 header 格式错误和 un-necessary 空行

Question

我是 SQL 的新手，我正在尝试运行查询以使用特定条件从数据库中提取警报并将结果输出到 csv 格式的文件。

我创建了下面的 SQL 脚本，但是 header 没有以所需的格式生成。

set markup HTML on ENTMAP on spool off PREFORMAT on;
set pagesize 0 embedded on;
set feedback off;
set termout off;
set trimout on;
spool on;
set trimspool on;
spool /tmp/scripts/outputFiles/calExport.csv REPLACE;
select (y.ALARM_DN||','||x.CO_NAME||','||to_char(y.ALARM_TIME, 'dd-MM-yyyy HH24:MI:SS')||','||y.ALARM_TEXT||','||y.ALARM_TYPE||','||y.PERCEIVED_SEVERITY||','||y.ADDITIONAL_INFO_1||','||y.ADDITIONAL_INFO_3||','||y.ADDITIONAL_INFO_2) from CTP_COMMON_OBJECTS x, FM_ALARM y where y.NE_GID=x.CO_GID and y.ALARM_STATUS=1;
spool off;
exit;

当前输出： '

'
(Y.ALARM_DN||','||X.CO_NAME||','||TO_CHAR(Y.ALARM_TIME,'DD-MM-YYYYHH24:MI:SS')||
    --------------------------------------------------------------------------------
xxxx/xxxx-143/xxxx-143,xxxxxxxxxxxxxxxxxxxx,xxxxxxxxxxxxxx
,03-10-2017 15:19:49,Dead Peer Detected,1,2,shared:N;,,additionalFaultId:0;

xxxx/xxxx-143/xxxx-143,xxxxxxxxxxxxxxxxxxxx,xxxxxxxxxxxxxxxxxx,13-09-
2017 12:45:48,LOS on unit 0, Ethernet interface 4,1,1,,,

xxxx/xxxx-143/xxxx-143,xxxxxxxxxxxxxxxxxxxx,03-10-2017 15:19:39,BA
NOTIFICATION,3,3,Files collected,,100 100 100 6450xxxx 1 0
 path=/xxxx-1(Left) additionalFaultId:6450;

问题：

如何更正 header 格式以匹配以下内容？

ALARM_DN,NAME,ALARM_TIME,TEXT,TYPE,SEVERITY,A,B,C

如何去除输出文件开头和结尾的"pre"标签？
如何去除输出中每行后面的空行？我使用了 set trimspool on 但空白行仍然存在。

感谢您的帮助。

要将标题更改为您想要的内容，请将您的 SQL*Plus 脚本更改为：

set markup HTML on ENTMAP on spool off PREFORMAT on;
set pagesize 0 embedded on;
set feedback off;
set termout off;
set trimout on;
SET HEADING OFF;
spool on;
set trimspool on;
spool /tmp/scripts/outputFiles/calExport.csv REPLACE;
SELECT 'ALARM_DN,NAME,ALARM_TIME,TEXT,TYPE,SEVERITY,A,B,C' FROM DUAL
UNION ALL
select (y.ALARM_DN||','||x.CO_NAME||','||to_char(y.ALARM_TIME, 'dd-MM-yyyy HH24:MI:SS')||','||y.ALARM_TEXT||','||y.ALARM_TYPE||','||y.PERCEIVED_SEVERITY||','||y.ADDITIONAL_INFO_1||','||y.ADDITIONAL_INFO_3||','||y.ADDITIONAL_INFO_2) from CTP_COMMON_OBJECTS x, FM_ALARM y where y.NE_GID=x.CO_GID and y.ALARM_STATUS=1;
spool off;
exit;
