How to Rename a Column in SQL Server | Easy Step-by-Step Tutorial

To execute this tutorial, you’ll need to have SQL Server installed on your device. In our examples throughout this article, I’ll be using SQL Server 2019.

Understanding the Basics of Renaming a Column

If you want to rename a column in SQL Server, you primarily need to understand the sp_rename stored procedure. This built-in stored procedure in SQL Server is used to rename columns and other user-defined objects in your database.

EXEC sp_rename 'table_name.old_column_name', 'new_column_name', 'COLUMN'

Rename A Column in SQL Server Using sp_rename

Let?s assume we have a table named ‘Employees’ with a column ‘EmplID’, and we want to rename this column to ‘EmployeeID’.

EXEC sp_rename 'Employees.EmplID', 'EmployeeID', 'COLUMN';

Now, your column ‘EmplID’ in the ‘Employees’ table is renamed to ‘EmployeeID’. It’s that simple!

Things to Consider

1. It’s important to note that this action cannot be undone. So, make sure that you really want to rename your column.

2. Using sp_rename will not automatically update the column name in to any related scripts, stored procedures, or user-defined functions etc. You must manually update those.

3. Renaming a column will not automatically rename constraints or indexes linked to it.

Safeguarding against Errors

It’s always a good practice to safeguard yourself against any possible errors or issues. Let’s have a look at a way to ensure an error-free column renaming:

IF EXISTS (
SELECT 1 
FROM sys.columns 
WHERE Name = 'EmplID' 
AND Object_ID = OBJECT_ID('Employees')
)
BEGIN
EXEC sp_rename 'Employees.EmplID', 'EmployeeID', 'COLUMN';
END

The above code first confirms the existence of the column and then renames it to avoid any errors.
