------------------------------------

             Summary: Valid statements rejected if Derby has not implicitly 
created the current user's schema.
                 Key: DERBY-6361
                 URL: https://issues.apache.org/jira/browse/DERBY-6361
             Project: Derby
          Issue Type: Bug
          Components: SQL
            Reporter: Rick Hillegas


There are many examples of statements failing because Derby has not implicitly 
created the schema associated with the current user. You don't see this if the 
schema is the default APP schema. But if the user is anyone other than APP, 
then various statements can fail. Maybe we should implicitly create a schema 
even if the user isn't APP. Right now, you get an error like this:

ERROR 42Y07: Schema 'ROOT' does not exist

The following script shows an example of this problem:

connect 'jdbc:derby:memory:db;create=true;user=esq';

create table licreq( domain varchar( 10 ) );

connect 'jdbc:derby:memory:db;user=root';

-- fails
ALTER TABLE esq.licreq ADD COLUMN u_domain GENERATED ALWAYS AS (UPPER(domain));

connect 'jdbc:derby:memory:db;user=app';

-- succeeds
ALTER TABLE esq.licreq ADD COLUMN u_domain GENERATED ALWAYS AS (UPPER(domain));
