Currently, only create/use DDLs for the database that is in the current thread is stored in the context. However, we do store CREATE DDL statements of other database tables in the context, if they are referred by the query. So, while replaying the context, if the other database is not present in the system, then we get an error. == SOLUTION == Store CREATE DATABASE DDLs of the databases to the context, if any of those database tables are referred by the original query.
