如何创建oracle sql脚本假脱机文件

发布于 2024-12-22 10:48:29 字数 497 浏览 4 评论 0原文

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。

  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，但我想做这样的事情，在开始结束块中我们计算一些值，并且我想假脱机这些结果。

谢谢。

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;

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.

Thanks.

这会将匿名块的输出假脱机到名为 output_.txt 的文件中，该文件位于本地 PC C: 驱动器的根目录中，其中是当前日期：

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

希望它有帮助...

编辑：

在您发表评论后，为游标的每次迭代输出一个值（我意识到在这个示例中每个值都是相同的，但您应该了解我的要点正在做）：

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;

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

Hope it helps...

EDIT:

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;

带线轴：

  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;

With spool:

  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;

从 BEGIN END 块进行假脱机非常简单。例如，如果您需要将两个表的结果假脱机到一个文件中，则只需使用 for 循环。下面给出示例代码。

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;
/

To spool from a BEGIN END block is pretty simple. For example if you need to spool result from two tables into a file, then just use the for loop. Sample code is given below.

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;
/
