如何在Windows命令脚本中使用sql*plus来控制流程？

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

我可能会从被调用的脚本（或条件，取决于要求）编写脚本script.sql itself.

例如，以下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

然后你可以打电话script.sql来自另一个.bat 文件像这样：

@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
