如何获得DBExpress TSqlConnection实际连接到的数据库的名称？ [英] How can I get the name of the database a DBExpress TSqlConnection is actually connected to?
问题描述
我正在测试一个相当老的Delphi 6应用程序，并且想显示TSqlConnection实际连接到的数据库名称，因此我可以快速查看是否连接到测试或生产数据库。
在sqlconnections.ini中，应用程序具有一个名为 Vienna的连接到如下定义的Firebird数据库：
Database = 192.168.1.15：ProductionDB（这是别名）
，为了测试目的，我将其替换为
Database = 192.168.1.15：TestDB。
但是我已经看到仅访问TSqlConnection的参数-List，数据库的值不起作用。此值始终设置为与设计模式下相同。
如何找出TSqlConnection实际连接到哪个数据库（在我的情况下为哪个Firebird别名） ？
监视表已引入FB 2.1.x：-）
所以尝试
从MON $ DATABASE中选择MON $ DATABASE_NAME pre>
或尝试
从MON $ ATTACHMENTS中选择MON $ ATTACHMENT_NAME
，其中MON $ ATTACHMENT_ID = CURRENT_CONNECTION

I'm testing a quite old Delphi 6 application and would like to display the database name the TSqlConnection is actually connected to, so I can see quickly if I'm connected to the test or production database.
In sqlconnections.ini, the app has a connection named 'Vienna' to a Firebird database defined like this: Database=192.168.1.15:ProductionDB (it's an alias) and I've replaced that for testing purposes with Database=192.168.1.15:TestDB.
But I've seen that just accessing the TSqlConnection's Params-List and there the value of 'Database' does not work. This value is always set the same as it is in design mode.
How can I find out which database (which Firebird alias in my case) the TSqlConnection is actually connected to?
monitoring tables were introduced into FB 2.1.x :-)
So try
select MON$DATABASE_NAME from MON$DATABASE
Or try
select MON$ATTACHMENT_NAME from MON$ATTACHMENTS
where MON$ATTACHMENT_ID = CURRENT_CONNECTION
