Myrna van Lunteren commented on DERBY-6662:
-------------------------------------------
The merge to 10.10 from 10.11 needed tweaking because 'goodStatement' and
'assertResults(...)' were not available in the 10.10 BaseJDBCTestCase, and also
I could not use 'String.contains()' as that gave me a build failure (10.10 came
out with support for 1.4.2; contains is from Java 1.5).

> DatabaseMetaData.usesLocalFiles() returns true for in-memory databases. And
> it also returns true for DatabaseMetaData.usesLocalFilePerTable(). The
> following script shows this:
> {noformat}
> connect 'jdbc:derby:memory:db;create=true';
> call syscs_util.syscs_register_tool( 'databaseMetaData', true );
> values usesLocalFiles();
> values usesLocalFilePerTable();
> {noformat}
> I think that these methods should return false because an in-memory database
> does not store tables in files.
