Another method that can be used to copy tables from the source database to the destination one is the SQL Server Export and Import wizard, which is available in SQL Server Management Studio.
You have the choice to export from the source database or import from the destination one in order to transfer the data.
This method is a quick way to copy tables from the source database to the destination one, if you arrange to copy tables having no concern with the tables’ relationships and orders.
When using this method, the tables’ indexes and keys will not be transferred. If you are interested in copying it, you need to generate scripts for these database objects.
If these are Foreign Keys, connecting these tables together, you need to export the data in the correct order, otherwise the export wizard will fail.
Feel free to read more about this method, as well as about some more methods (including generate scripts, SELECT INTO and third party tools) in this article:
