如何创建Oracle SQL脚本假脱机文件 [英] How to create a oracle sql script spool file
问题描述
我有一个关于假脱机程序结果的问题.我的示例sql脚本如下所示.
I have a question about spooling the the results of my program. My sample sql script looks like this.
whenever sqlerror exit failure rollback
set heading off
set arraysize 1
set newpage 0
set pages 0
set feedback off
set echo off
set verify off
declare
ab varchar2(10) := 'Raj';
cd varchar2(10);
a number := 10;
c number;
d number;
begin
c := a+10;
select ab,c into cd,d from dual;
end;
SPOOL
select cd,d from dual;
SPOOL OFF
EXIT;
上面的脚本不起作用,但是我想做这样的事情,其中在begin end块中我们计算一些值,并且我要假脱机处理那些结果.
The above script does not work, but I want to do something like this where in the begin end block we compute some values and i want to spool those results.
谢谢.
推荐答案
这会将匿名块的输出假脱机到位于本地PC C:驱动器根目录中的名为output_<YYYYMMDD>.txt
的文件中,其中<YYYYMMDD>
是当前日期:
This will spool the output from the anonymous block into a file called output_<YYYYMMDD>.txt
located in the root of the local PC C: drive where <YYYYMMDD>
is the current date:
SET SERVEROUTPUT ON FORMAT WRAPPED
SET VERIFY OFF
SET FEEDBACK OFF
SET TERMOUT OFF
column date_column new_value today_var
select to_char(sysdate, 'yyyymmdd') date_column
from dual
/
DBMS_OUTPUT.ENABLE(1000000);
SPOOL C:\output_&today_var..txt
DECLARE
ab varchar2(10) := 'Raj';
cd varchar2(10);
a number := 10;
c number;
d number;
BEGIN
c := a+10;
--
SELECT ab, c
INTO cd, d
FROM dual;
--
DBMS_OUTPUT.put_line('cd: '||cd);
DBMS_OUTPUT.put_line('d: '||d);
END;
SPOOL OFF
SET TERMOUT ON
SET FEEDBACK ON
SET VERIFY ON
PROMPT
PROMPT Done, please see file C:\output_&today_var..txt
PROMPT
希望有帮助...
在为每个游标的迭代输出一个值后(我意识到在此示例中每个值都将是相同的,但是您应该了解我在做什么的要点)后发表评论:
After your comment to output a value for every iteration of a cursor (I realise each value will be the same in this example but you should get the gist of what i'm doing):
BEGIN
c := a+10;
--
FOR i IN 1 .. 10
LOOP
c := a+10;
-- Output the value of C
DBMS_OUTPUT.put_line('c: '||c);
END LOOP;
--
END;
