Re: Get database name in OCI or PL/SQL

Michael,

You can try the following code in PL/SQL

DECLARE
IDontKnowWhereIHaveConnected VARCHAR2(25); BEGIN

     IDontKnowWhereIHaveConnected := database_name;
     dbms_output.put_line('I am connected to ' || IDontKnowWhereIHaveConnected);
END;     

The database name is defined in dbms_standard
