Methods to Transfer Table Data and Schema from One Database to Another
Suppose there are two databases-

Destination – “databasetest2”
In source database “databasetest1”, there is a table named EMP containing data like Name, Address, City, and so on. To copy the EMP table data and schema from source database to destination database. You can try any of the method mentioned below:

Use this query to copy database in SQL Server
Syntax:
Select * into DestinationDB.dbo.tablename from SourceDB.dbo.SourceTable
Example:
Select * into databasetest2.dbo.stu from databasetest1.dbo.emp
Note: If you want to copy other database objects such as indexes, triggers, and constraints, etc. then you need to use the second method Generate Scripts, prepare the script individually for this, after that you need to apply the script to the destination database.
