Renaming a Table in SQL Server: A Comprehensive Guide for Devs

Greetings, Devs! Are you looking for a step-by-step guide on how to rename a table in SQL Server? Look no further! In this article, we will walk you through the entire process of renaming a table in SQL Server. We will also provide you with some frequently asked questions (FAQs) about renaming tables in SQL Server. Let’s get started!

Understanding the Basics of Renaming a Table in SQL Server

Before we dive into the steps of renaming a table in SQL Server, let’s first understand the basics of renaming a table. Renaming a table in SQL Server is a simple process that involves changing the name of the table. When you rename a table, all the associated objects like triggers, stored procedures, and views that reference the table also get updated with the new name. Renaming a table is often useful when you want to give the table a more descriptive name or change the name to follow a naming convention.

When you rename a table in SQL Server, the table’s name is updated in the sys.objects table, which stores information about all the objects in the database. The old name of the table is also updated in the sys.sql_expression_dependencies and sys.sql_modules tables, which store information about the dependencies of the object.

Now that we have a basic understanding of renaming a table let’s move on to the steps involved.

Step-by-Step Guide to Rename a Table in SQL Server

Step 1: Connect to SQL Server Management Studio (SSMS)

The first step in renaming a table in SQL Server is to connect to SSMS. Open SSMS and connect to the SQL Server database where the table exists.

Step 2: Expand Databases and Locating the Table to be Renamed

Next, expand the Databases folder and locate the database that contains the table you want to rename. Expand the database, and you should see a list of objects within that database.

Find the table that you want to rename, and right-click on it. From the dropdown menu, select the ‘Rename’ option.

Step 3: Rename the Table

Once you select the ‘Rename’ option, the table name will become editable. Type in the new name for the table, and hit ‘Enter’.

This will update the table’s name in the sys.objects table and all associated objects like views, stored procedures, and triggers that reference the table will also be updated with the new name.

Step 4: Verify the Table Rename

To verify that the table has been renamed successfully, expand the database that contains the table and look for the new table name. You can also run a SELECT query to retrieve data from the table to ensure that everything is working correctly.
