This command enables you to take a copy of the schema and the statistics for an existing database into a new database. According to the documentation, DBCC CLONEDATABASE
Creates a new destination database that uses the same file layout as the source but with default file sizes as the model database.
Creates an internal snapshot of the source database.
Copies the system metadata from the source to the destination database.
Copies all schema for all objects from the source to the destination database.
Copies statistics for all indexes from the source to the destination database.
I knew there were ways of scripting out statistics, but DBCC CLONEDATABASE looks like a new and interesting beast.
