SQL SERVER – How to Rename a Column Name or Table Name

I often get requests from blog reader for T-SQL script to rename database table column name or rename table itself. Both are easy with sp_RENAME, so let me show how to rename a column and a table.

Here is a video demonstrating the discussion

The script for renaming any column :
sp_RENAME 'TableName.[OldColumnName]' , '[NewColumnName]', 'COLUMN'

The script for renaming any object (table, sp etc) :
sp_RENAME '[OldTableName]' , '[NewTableName]'

This article demonstrates two examples of renaming database object.

1. Renaming database table column to new name.
2. Renaming database table to new name.

In both the cases we will first see existing table. Rename the object. Test object again with new name.

1. Renaming database table column to new name.

Example uses AdventureWorks database. A small table with name “Table_First” is created. Table has two fields ID and Name.

Now, to change the Column Name from “Name” to “NameChange” we can use command:

USE AdventureWorks
GO
sp_RENAME 'Table_First.Name', 'NameChange' , 'COLUMN'
GO 

Following Fig. show use of SP_RENAME Command

You can see the column name “Name” is now changed to “NameChange”.

USE AdventureWorks
GO
SELECT *
FROM Table_First
GO

Following fig. verify that the column name has been changed.

2.Renaming database table to new name.

We can change the table name too with the same command.

sp_RENAME 'Table_First', 'Table_Last'
GO

Following fig. Shows how we can change Table Name.

Now, the table name “Table_First” is renamed as “Table_Last”.

“Table_First” will no longer be available in database. We can verify this by running script:

USE AdventureWorks
GO
SELECT *
FROM Table_First
GO

The Messages shows an error “Invalid object name ‘Table_First’.”

To check that the new renamed table exist in database run script:

USE AdventureWorks
GO
SELECT *
FROM Table_Last
GO

You can see the same data now available in new table named “Table_Last”
