> Currently, if one creates a cache without DDL (via {{QueryEntity}} or {{indexedTypes}}), separate schema for this cache is created. Schema name is case sensitive, so to connect to it with JDBC driver, it's required to provide the name in quotes. Here is how it looks like in SqlLine:
> {noformat}
> ./bin/sqlline.sh -u jdbc:ignite:thin://127.0.0.1/\"CacheQueryExamplePersons\"
> {noformat}
> However, if name is provided without quotes, driver still connects, but then fails with a very unclear exception when a query is executed:
> {noformat}
> ./bin/sqlline.sh -u jdbc:ignite:thin://127.0.0.1/CacheQueryExamplePersons{noformat}
> This is a huge usability issue. We should disallow connections to schema that does not exist, throw exception in this case. Exception should provide proper explanation how to connect properly.
