There are various situations where the requirement to transfer tables from one database to another arises, such as during maintenance, testing, demonstrations, migrations, or when moving data to a different instance. This task can be accomplished through several methods provided by SQL Server, making it a straightforward process.
Individuals proficient in SQL queries can effortlessly perform the same task within SQL Server. However, those with limited familiarity in SQL queries and Transact-SQL might encounter challenges when attempting the operation.
In this article, we’ll guide you through how to copy tables from one database to another in SQL Server using different methods available and discuss a little on SQL Server database file corruption and how to repair corrupt SQL database. SQL administrators will have to do all these tasks now or then to keep their databases healthy and to work always.
Get Kernel for SQL Database recovery tool to repair corrupt or damaged MDF/NDF file. The software is also capable to preserve the original structure and properties of data.
To copy tables, we need access to specific databases – the source server and the destination server. Here,
Source Database: TechForums19
Destination Database: TechForums20
This method makes utilization of SELECT INTO query.
Select * into TechForums20.userforum.user from TechForums19.userforum.user
The preceding query exclusively duplicates the table schema and data. If you desire to replicate objects, indexes, triggers, and constraints, accomplishing this task via SQL queries or commands is not feasible. In this article, we will delve into methods for copying the remaining components of the database.
The second approach for duplicating tables in SQL Server involves using the Export and Import wizard, which is accessible within SQL Server Management Studio. With this option, users have the flexibility to either import data from the destination database or export data from the source database for the purpose of transferring or copying information.
Follow below steps to copy tables from one database to another in SQL Server:
Note: For this guide, TechForums19 is the source database name as specified above. Change the source database name with yours and mention the server name & authentication method.
Note: Again, mention the Server name and authentication method in this step as well.
Note:
To ensure that the tables you’ve chosen are generated in the destination database, click the Edit Mappings button, and check the Create destination table option.
If the tables include an identity column, check the “Enable identity insert” option, and then click the “Ok” button.
If selected more than one table to copy to the destination database, click on Edit Mappings again, and check for all tables one after the other.
Note: Make sure to specify correct names of both Source & Destination databases, to transfer tables from one database to another.
SQL Server Management Studio provides a speedy method for duplicating tables in SQL Server. However, it falls short when it comes to transferring or replicating the indexes and keys associated with the tables.
If you intend to replicate the table indexes and keys, you will need to utilize the Generate Scripts method.
This method enables you to copy not only the table schema and data but also objects, indexes, trigger, constraints, keys, etc.
Go through the steps below to generate a script to fully copy tables from one database to another in SQL Server:
Whenever you undertake a task or job involving a SQL Server database, there exists a minor but potential risk of data loss or corruption of the SQL Server database files. This can occur due to incorrect execution or mishandling of the database files. In such critical scenarios, the frustration of retrieving data from inaccessible MDF/NDF database files can become nearly insurmountable.
In scenarios of SQL Server Database file corruption or damage, we recommend using a SQL recovery .
This tool empowers you to effortlessly restore corrupted, impaired, or inaccessible MDF and NDF files, all the while preserving their original file structure and properties. It also allows you to recover MDF files after a ransomware attack. With this tool, you can recover SQL all objects like tables, triggers, functions, rules, deleted records, etc.
It provides the user with full control over database objects and sets no restriction over the file size.
Furthermore, we have ensured compatibility with a broad spectrum of Microsoft SQL Server editions, spanning from SQL Server 2000 to 2019. This means that regardless of the specific SQL Server version running on your system, our product will be readily available for use upon completing the installation.
Migrating or duplicating tables from one SQL Server database to another can be a straightforward task, but certain approaches can be time-consuming and intricate. Moreover, in case of any mishap during the operation, both the data and the database file become susceptible to potential corruption and harm. To address these challenges effectively, consider employing Kernel for SQL Database Recovery, a leading third-party SQL recovery tool designed for SQL administrators. This tool offers compatibility with all SQL versions, including SQL Server 2019, ensuring comprehensive support for your database recovery needs.
