In MySQL and PostgreSQL is is possible to define your entities in multiple schemas. In MySQL terminology, it is called database, but from implementation point of view, it is a schema.
To use multiple schemas, your connection needs to have access to all of them (multiple connections are not supported).
All you need to do is simply define the table name including schema name in
Then use those entities as usual. Resulting SQL queries will use this
tableName value as a
table name so as long as your connection has access to given schema, everything should work
