根据用户登录名自动过滤记录？ [英] automatically filter records based on a userlogin name??
问题描述
大家好，对MySQL来说还是个新手。我是
想知道是否有办法根据mysql用户登录名自动过滤
记录？
我有为了更有效地管理数据库，我想要组合几个数据库
。
- 我正在使用MySQL 4.1.12和我'我目前正在测试5.0.14
- 我有一个每个用户帐户的数据库。
- 每个数据库都有相同的模式和实体关系模型。
- 我必须通过各种连接提供对数据库的原始访问（odbc，mysql客户端）
例如，当用户登录时，通过任何应用程序/ odbc连接/
mysql utiltiy，MySQL服务器设置变量DatabaseAccount = $ loginusername，
其中DatabaseAccount是所有表中的表列。服务器
只返回与DatabaseAccount名称匹配的记录。
我认为这将是命名空间，但我确实搜索了mysql数据库命名空间<在谷歌的
和一堆.Net的东西回来了。
感谢您的时间，
Matt

您好，
您可以使用存储过程执行此操作。使用''select user（）''，您可以查询已登录用户的
。您可以例如设置一个参考表，用户
可以选择哪一组数据并用准备好的语句设置一个查询，
你在哪里组建部件。
也许这听起来有点复杂，如果你需要一些更详细的帮助 -
这可能是我在博客上写的一个很好的例子;-)。

我想我们必须设置一个触发器来检测SELECT，INSERT
UPDATE和DELETE语句并运行进一步过滤的存储过程
返回的结果（如果有的话）。如果在数据库核心中内置了这样一个功能，那将会很酷。
我期待着阅读你的博客Markus。我认为这将是一个整洁的
小写。
谢谢，

Hi everyone, still pretty new to MySQL. I was
wondering if there is a way to automatically filter
records based on a mysql userlogin name??
I have serveral databases that I want to combine
in order to manage the databases more efficiently.
- I''m currently using MySQL 4.1.12 and I''m currently testing 5.0.14
- I have a databases for each user account.
- Each database has the same schema and entity relation model.
- I have to provide raw access to the database via various connections (odbc, mysql clients)
Example, when the user logs in, via any applicaition/odbc connection/
mysql utiltiy, MySQL server sets a variable DatabaseAccount=$loginusername,
where DatabaseAccount is a table column in all the tables. The server
only returns records that match the DatabaseAccount name.
I think this would be a namespace but I did search for "mysql database namespace"
in google and got a bunch of .Net stuff back.
Thanks for your time,
Matt

Hi,
you can do this with a stored procedure. With ''select user()'' you can query
the user who''s logged in. You can e.g. set up a reference table, which user
can select which set of data and set up a query with a prepared statement,
where you build the parts together.
Maybe this sounds a bit complicated, if you need some more detailed help -
this could be a nice example that I could write about in my weblog ;-).

I suppose we would have to setup a Trigger to detects SELECT, INSERT
UPDATE and DELETE statements and run the Stored Procedure that further filters
the returned results, if any. It would be cool if such a feature where
built into the database core.
I look forward to reading your blog Markus. I think it would be a neat
little write up.
Thanks,
Matt
