How do I query the database name in Oracle SQL Developer? I have tried the following and they all fail:
SELECT DB_NAME();
SELECT DATABASE(
I know this is an old thread but you can also get some useful info from the V$INSTANCE
view as well. the V$DATABASE
displays info from the control file, the V$INSTANCE
view displays state of the current instance.
DESCRIBE DATABASE NAME; you need to specify the name of the database and the results will include the data type of each attribute.
try this:
select * from global_name;
Once I realized I was running an Oracle database, not MySQL, I found the answer
select * from v$database;
or
select ora_database_name from dual;
Try both. Credit and source goes to: http://www.perlmonks.org/?node_id=520376.
Edit: Whoops, didn't check your question tags before answering.
Check that you can actually connect to DB (have the driver placed? tested the conn when creating it?).
If so, try runnung those queries with F5
You can use the following command to know just the name of the database without the extra columns shown.
select name from v$database;
If you need any other information about the db then first know which are the columns names available using
describe v$database;
and select the columns that you want to see;
