Question

我想使用来自sql脚本的过滤数据，并使用它在数据库中使用过滤列表进行升级以运行升级。

1）我有一个每天都在变化的SQL文件，它看起来像以下内容：

select 
'OBJECT1' object_name, 
'PACKAGE BODY' object_type, 
'999999' target_vers, 
(Select statement which finds current version),
Decode (decode which comperes target version and current version) status 
from DUAL union

选择（相同的5列） .. ... ..

它可以达到100多个选择

2）我只想使用目标版本>当前版本（有时目标版本可能是<当前版本）

的表条目

3）对象名称对应于.code目录，在该目录中找到了相应的sql，view，pks。

4）经过过滤的步骤之后，我想在db服务器中运行这些sql文件（看起来它需要循环执行）。

5）由于我是cmd / batch的新手，所以不确定如何执行此操作。

for /f  %%k in ('sqlplus -s %LOGIN%/%LOGIN%@%DBSERVER% @%SCRIPTPATH%\CHECK_CODE.sql') do (
set theValue=%%k
)

上面的代码运行上面提到的sql文件，

spool new.txt 
select ...... 
spool off 
/ 
exit

这将返回以下txt文件

OBJECT_NAME                 OBJECT_TYPE  TARGE                                  
--------------------------- ------------ -----                                  
INSTALLED_VERS                                                                  
--------------------------------------------------------------------------------
STATUS                                                                          
-------------------------                                                       
OBJECT_NAME              PACKAGE BODY 72021                                  
72021                                                                           
--- INSTALLED ---

现在，我只想遍历所需的对象来更新数据库。

for /f  %%a in ('List of entries which need upgrade') 
do (
sqlplus -s %LOGIN%/%LOGIN%@%DBSERVER% @%%a.[object_name].[object extension]
)

问题是如何从第一个SQL脚本中获取过滤后的数据到CMD中的数组中，然后使用它们来运行SQL文件（与object_name相同）

最终做了类似的事情：

从多个select UNION返回表放入数组
