Certain situations such as maintenance, testing, demonstration, migration, transfer to a different instance, and so on influence the requirement of copying SQL tables from one database to another. This is a very easy procedure and can be performed in different ways.
It can be easy for the technical users who have knowledge about the SQL queries and can easily perform the same procedure in SQL Server but it can be a difficult task for the novice person who has no/ little knowledge.
The Manual Methods to Copy Tables in SQL Server
So the things that you need to copy tables, we have to access particular databases – the source server and the destination server.
This method query can copy the table schema and data only if you want to copy objects, indexes, triggers, and constraints that are not possible with SQL queries/commands. Later in this article, I will explain to you the procedure by which you can copy the rest of the database items.
Try the SQL Server Management Studio
It is the second procedure that can copy tables in SQL Server through Export and Import wizard, in SQL Server Management Studio. In this, the user can pick either to import from the destination database or to export from the source database to transfer/copy the data.
You have to follow these steps to copy tables from one database to another in SQL Server:
1. Open SQL Server Management Studio.
2. Right-tap on Database > Tasks > select the Export Data command in the object explorer.
3. Then, state the Server Name, Authentication method, and the Source database name, and tap on the Next.
While performing this step, change the source database name with yours and specify the server name & authentication method.
4. Then, state the Destination database name and tap on the Next.
Note: You have to provide the Server name and authentication method again in this step.
5. Choose the Copy data from one or more tables or views and Tap on the Next.
6. Now, choose the Source Tables and Views wizard will be displayed on-screen; choose the Tables of your choice to copy from source database to destination database, and tap on the Next.
Note: Ensure the tables of your choice to generate in the destination database, tap on the Edit Mappings and Mark on the Create destination table.
In case, if the tables have the identity column, then mark the Enable identity insert option, and tap on the Ok button.
If picking more than one table to copy to the destination database, tap on the Edit Mappings again and review all the tables.
7. Once you have reviewed all the tables through Edit Mappings, tap on the Next in the Select Source Tables and Views.
8. Now, open the Save and Run wizard, tap on Next.
9. Tap on the Finish.
Note: Kindly provide the correct names of the Source & Destination databases so that you can move your tables from one database to another.
You can use the SQL Server Management Studio for Copying tables SQL Server as itis a quick method to perform the process, but it is unable to transfer/copy the table’s indexes and keys.
In case you want to copy the table indexes & keys, then use the Generate Scripts method.
This method allows you to imitate the table schema, data, objects, indexes, trigger, constraints, keys, etc.
You have to follow these steps in order to create a script to fully copy tables from one database to another in the SQL Server:
1. First, Open the SQL Server.
2. Press the Right-tap on the database name > Tasks > Generate Scripts.
3. Once Script Wizard opens, tap on the Next button.
4. Choose the Database of your choice for which you want to Generate Script.
5. Choose the Object types and tap on the Next button.
6. Choose the tables to copy.
7. Pick the particular Output option for the script.
8. Change the database name of your choice to execute the script.
9. Process is completed
What if the Database Files get Corrupted or Damaged?
While performing tasks with SQL Server, you always have the probability of data loss or SQL Server database file corruption. It will be worse if your data gets corrupted or damaged as it is impossible to get back the data from the inaccessible MDF/NDF database files. So, to deal with this situation you should get an alternative tool/method.
You can use the SQL Database Recovery offers to restore and retrieve corrupt NDF and MDF file extension without misusing the original data. This software is highly cooperative with Windows 10, 8, 7, Vista, 2003, XP, and 2000.
This blog explains the procedure to Copy SQL Tables from One Database to Another, its reasons, and its manual and alternative methods. Users should save their time by using the alternative tool which will help you to perform your procedure smoothly and it also will deduct the chances of the database or data files getting corrupted and damaged.
