Renaming a Table in SQL Server

Hello Dev, welcome to this journal article on how to rename a table in SQL Server. Renaming a table can be a common requirement in many scenarios such as changing the table name to better reflect its contents or complying with naming conventions. In this article, we will take you through the steps necessary to rename a table in SQL Server.

1. Back Up Your Database

The first and most important step before making any changes to your database is to back it up. This ensures that in case anything goes wrong during the renaming process, you have a backup to restore from. You can use the SQL Server Management Studio (SSMS) to create a backup of your database.

To create a backup, follow these steps:

Step
Action
1
Open SSMS and connect to your database.
2
Right-click on the database and select “Tasks” > “Back Up”.
3
In the “Back Up Database” dialog box, select the destination for the backup, and click “OK”.

2. Create a New Table with the Desired Name

Once you have a backup of your database, the next step is to create a new table with the desired name. To do this, follow these steps:

Step
Action
1
Open SSMS and connect to your database.
2
Right-click on the database and select “New Query”.
3
In the query window, type the following command:

CREATE TABLE new_table_name (column1 datatype1, column2 datatype2, ...);
4
Execute the query to create the new table.

3. Copy the Data from the Old Table to the New Table

The next step is to copy the data from the old table to the new table. To do this, you can use the SELECT INTO statement. Follow these steps:

Step
Action
1
In the query window, type the following command:

SELECT * INTO new_table_name FROM old_table_name;
2
Execute the query to copy the data.

4. Drop the Old Table

The last step is to drop the old table. To do this, use the DROP TABLE statement. Follow these steps:

Step
Action
1
In the query window, type the following command:

DROP TABLE old_table_name;
2
Execute the query to drop the old table.
