How to Fix "Cannot open user default database" Error in SQL 2012 Login

Introduction

When working with SQL Server 2012, you may come across an error message stating "Cannot open user default database" when trying to login. This error indicates a problem with the default database associated with the user's login credentials. Thankfully, there are several simple solutions to fix this issue. In this article, we will discuss the causes of this error and provide step-by-step solutions to resolve it.

Causes of "Cannot open user default database" Error

  1. Invalid Database Configuration: One of the common causes of this error is an invalid or non-existent default database configuration. If the database associated with the user's login credentials is offline, inaccessible, or has been deleted, you may encounter this error.

  2. Incorrect Login Credentials: Another cause of this error is when the provided login credentials are incorrect. If the username or password is entered incorrectly, SQL Server will fail to open the user's default database.

  3. Corrupted User Profile: Occasionally, the user profile associated with the SQL Server login can become corrupted. This corruption may prevent SQL Server from accessing the default database.

Solutions to "Cannot open user default database" Error

To fix the "Cannot open user default database" error in SQL 2012 login, you can follow these step-by-step solutions:

Solution 1: Using SQL Server Management Studio

  1. Open SQL Server Management Studio (SSMS) and connect to the SQL Server instance where the error occurs.

  2. Navigate to the "Security" folder in the Object Explorer panel, then expand the "Logins" folder.

  3. Right-click on the login experiencing the error and select "Properties" from the context menu.

  4. In the Login Properties window, navigate to the "General" tab. Locate the "Default database" dropdown and ensure it is set to a valid and accessible database.

  5. If the default database is set to a non-existent or inaccessible database, select a valid database from the dropdown.

  6. Click "OK" to save the changes.

Solution 2: Using Transact-SQL Commands

Alternatively, you can use Transact-SQL commands to address the "Cannot open user default database" error. Follow these steps:

  1. Open SQL Server Management Studio and open a new query window.

  2. Execute the following query, replacing "username" with the actual login name experiencing the error:

ALTER LOGIN [username] WITH DEFAULT_DATABASE = [valid_database]
  1. Replace "[valid_database]" with the name of a valid and accessible database.

  2. Execute the query by clicking on the "Execute" button or pressing the F5 key.

Solution 3: Re-creating User Profile

In some cases, a corrupted user profile can cause the "Cannot open user default database" error. To re-create the user profile, follow these steps:

  1. Open SQL Server Management Studio and connect to the SQL Server instance.

  2. Expand the "Security" folder and select the login that encounters the error.

  3. Right-click on the login and choose "Delete" to remove the login.

  4. Re-create the login by right-clicking on the "Logins" folder and selecting "New Login."

  5. Enter the necessary login details and configure the default database to a valid and accessible database.

  6. Click "OK" to create the new login.

Frequently Asked Questions
