i have an oracle Database with 3 users (user1/user1 , user2/user2, user3/user3) and i have the same number/structure of tables in the 3 users.
我有一个拥有3个用户的oracle数据库(user1 / user1,user2 / user2,user3 / user3),我在3个用户中拥有相同数量/结构的表。
my issue is : when i want to update for example my table1 in the user1 , i want to update the same table1 in the user2 and user3 in order to keep them updated , i want to execute my script once , without login to the other users and execute the same script because i will have an other users (4 and 5 ) and this will take a lot of time to execute one script in the all users.
我的问题是:当我想更新例如我在user1中的table1时,我想更新user2和user3中的同一个table1以保持更新,我想执行我的脚本一次,而无需登录其他用户并执行相同的脚本,因为我将有其他用户(4和5),这将花费大量时间在所有用户中执行一个脚本。
i'm wondering if there is a tool or technique to execute an script once for multiple users.
我想知道是否有一个工具或技术可以为多个用户执行一次脚本。
Thanks in advance.
提前致谢。

You can use SQLPlus to build a script that runs your script once per user. Say you have a script like this:
您可以使用SQLPlus构建一个脚本,每个用户运行一次脚本。假设您有这样的脚本:
script.sql:
script.sql:
select count(1) from obj;
and you want to run it for two users; you can build a script like the following:
你想为两个用户运行它;您可以构建如下的脚本:
scriptLauncher.sql:
scriptLauncher.sql:
conn alek/****@xe
@d:\script
conn hr/****@xe
@d:\script
The result:
结果:
SQL> @d:\scriptLauncher
Connected.
COUNT(1)
----------
15
Connected.
COUNT(1)
----------
35
Of course this means that you have to store your passwords in a plain text fle, which may be a security risk to take in consideration.
当然,这意味着您必须将密码存储在纯文本文件中,这可能存在安全风险。

Try this if your script has only DML operations
如果您的脚本只有DML操作,请尝试此操作
SET SERVEROUTPUT ON
DECLARE
TYPE my_users_type IS VARRAY (5) OF VARCHAR (256);
my_users my_users_type;
BEGIN
my_users := my_users_type ('USER1', 'USER2', 'USER3'); --your users
FOR i IN my_users.FIRST .. my_users.LAST LOOP
EXECUTE IMMEDIATE 'ALTER SESSION SET CURRENT_SCHEMA =' || my_users (i);
@D:\yourscript.SQL; --your script with path
END LOOP;
end;
/
yourscript.SQL should contain only DML commands splitted by ; Nothing else. Or you can modify it - create a procedure has string parameter. Parameter will be single DML command which will be executed in loop for all users.
yourscript.SQL应该只包含由分割的DML命令;没有其他的。或者你可以修改它 - 创建一个过程有字符串参数。参数将是单个DML命令,它将在循环中为所有用户执行。
or just use
或者只是使用
ALTER SESSION SET CURRENT_SCHEMA = USER1
@D:\yourscript.SQL;
ALTER SESSION SET CURRENT_SCHEMA = USER2
@D:\yourscript.SQL;
ALTER SESSION SET CURRENT_SCHEMA = USER3
@D:\yourscript.SQL;
No limitations to your script yourscript.SQL, except don't use schema names as prefixes in your DML operations
脚本yourscript.SQL没有限制,除了在DML操作中不使用模式名称作为前缀
P.S. Executing user should have enough rights.
附:执行用户应该有足够的权限。

I would have a folder in which I have
我有一个文件夹,我有
- the sql script
- sql脚本
- an OS script which connects to each database at a time and runs the script
- 一个OS脚本,它一次连接到每个数据库并运行脚本
OR
要么
Run it with a user which has rights over all the other 3 and personalize the script so it runs for each.
使用对所有其他3具有权限的用户运行它并对脚本进行个性化,以便为每个脚本运行。
