How can i identify the environment name or database name in the PL/SQL code

Question

Hi,
I am using UTL_FILE to genearate the files.,
My problem is, I have to design the common sql file , which can be executed in 2 diffrent environments ( Say QA & DEV ) , with no parameters. It has to identify the environment and based on the environment , it has to generate the concern files.,
The only change needs to be incorporated is , file names , which will change based on the environment.,
can nay one tell me , how can i identify the environment name or database name in the PL/SQL code ??

In this case, USEC_GI_DEV.NA.XXXNET.NET is a TNS alias. That alias exists only on the client machine. There is no way to access that information on the database server.
You would have to find something in the v$database or v$instance table that uniquely identifies the database (and you may need some help from the DBAs to do this because you need to ensure that the data element you choose is compatible with whatever refresh process(es) are used in your environment).
Now, if you are writing a stand-alone SQL*Plus script, SQL*Plus, as a client tool, does have access to the TNS alias in later versions. But that is a client-side determination, not a server-side determination.
