I have created a database named \'movie_db\', set default schema to APP. Then created a sample table named \'USERS\'.
My connection to DB is as follows:
There are basically two ways to control the default schema name:
If you haven't issued a SET SCHEMA statement, then Derby will use your username as the schema name.
So if you login as user "APP", and don't issue a SET SCHEMA statement, then your schema name will be APP.
