我正在尝试使用SQL*Plus来控制一个小的Windows命令脚本。
基本上,我想执行一些pl/sql(可能从视图或表中选择或执行一个函数),它显示数据库中某些行的状态,然后根据行的状态执行一些windows命令。
我的问题是如何将结果返回到命令脚本中。
sqlplus user/password@server @script.sql
IF <CONDITIONAL HERE BASED on script.sql results> GOTO :runprocess
REM log and email that process had to be skipped
EXIT
:runprocess
REM run various Windows service commands
最佳答案
我可能会从调用的script.sql
本身编写脚本(或条件脚本,取决于需求)。
例如,下面的script.sql
创建一个.bat文件windows_commands.bat
:
set feedback off
set echo off
set trimspool on
set termout off
set serveroutput on size 100000 format wrapped
set lines 500
set pages 0
-- create the bat file to be executed later:
spool windows_commands.bat
declare
c number;
begin
select count(*) into c from dual;
-- depending on a conditional, write the stuff to be executed into the
-- bat file (windows_commands.bat)
if c = 1 then
dbms_output.put_line('@echo everthing ok with dual');
else
dbms_output.put_line('@echo something terribly wrong with dual');
end if;
end;
/
spool off
exit
然后可以从另一个.bat文件调用
script.sql
,如下所示:@rem create oracle session, call script.sql
sqlplus %user%/%password%@%db% @script.sql
@rem script.sql has created windows_commands.bat.
@rem call this newly created bat file:
call windows_commands.bat
