[英]How to create a oracle sql script spool file
I have a question about spooling the the results of my program. 我有一个关于假脱机程序结果的问题。 My sample sql script looks like this.
我的示例sql脚本看起来像这样。
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;
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. 上面的脚本不起作用,但我想做这样的事情,在开始结束块我们计算一些值,我想假设这些结果。
Thanks. 谢谢。
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: 这会将匿名块的输出假脱机到名为
output_<YYYYMMDD>.txt
的文件中,该文件位于本地PC C:驱动器的根目录中,其中<YYYYMMDD>
是当前日期:
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
Hope it helps... 希望能帮助到你...
EDIT: 编辑:
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): 在您的注释为光标的每次迭代输出一个值之后(我意识到在这个例子中每个值都是相同的,但你应该得到我正在做的事情的要点):
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;
With spool: 使用线轴:
set heading off
set arraysize 1
set newpage 0
set pages 0
set feedback off
set echo off
set verify off
variable cd varchar2(10);
variable d number;
declare
ab varchar2(10) := 'Raj';
a number := 10;
c number;
begin
c := a+10;
select ab,c into :cd,:d from dual;
end;
SPOOL
select :cd,:d from dual;
SPOOL OFF
EXIT;
To spool from a BEGIN
END
block is pretty simple. 从
BEGIN
END
块进行假脱机非常简单。 For example if you need to spool result from two tables into a file, then just use the for loop
. 例如,如果您需要将两个表的结果假脱机到文件中,那么只需使用
for loop
。 Sample code is given below. 示例代码如下。
BEGIN
FOR x IN
(
SELECT COLUMN1,COLUMN2 FROM TABLE1
UNION ALL
SELECT COLUMN1,COLUMN2 FROM TABLEB
)
LOOP
dbms_output.put_line(x.COLUMN1 || '|' || x.COLUMN2);
END LOOP;
END;
/
In order to execute a spool file in plsql Go to File->New->command window -> paste your code-> execute. 为了在plsql中执行假脱机文件,请转到文件 - >新建 - >命令窗口 - >粘贴代码 - >执行。 Got to the directory and u will find the file.
到达目录,你会找到该文件。
