As per my understanding, You can use BCP Tool to Import/Export only the data.
Other such tools can be via SSIS Data Import/Export Wizard, Select INTO statement.
Or you can also export the table data onto a csv & import it into the new database via BULK INSERT.
Hope this helps!
If you have new database with same structure and metadata as old db, bettter to take full backup and restore it.
Other option could be SSIS package. If you have huge data in the tables, you may need to drop the indexes on destination db and recreate them. Other thing like table relations have to be considered (Load primary tables first).
