Background
Error Code 4060 typically means that the client could not connect to the specified database in Azure SQL Database. It often happens when the database name is incorrect, the login credentials don’t match, or the database is unavailable due to access control or network settings. This error message is commonly associated with login failures or permission issues when attempting to access a database.
Error Explanation
The error message for Error Code 4060 generally reads:
Error 4060: Cannot open database “<DatabaseName>” requested by the login. The login failed.
This error indicates that the Azure SQL Database server was able to process the login request but could not access the specified database, possibly due to authentication failures, lack of permissions, or incorrect database configuration.
Common Causes
- Invalid Database Name: The database name in the connection string is incorrect, or the database does not exist on the server.
- Incorrect Login Credentials: The username or password is incorrect, leading to authentication failure.
- Insufficient Access Rights: The login does not have sufficient permissions to access the specified database.
- Firewall Restrictions: The Azure SQL Database firewall may be blocking access from the client’s IP address.
Steps to Troubleshoot and Resolve Error Code 4060
Step 1: Verify Database Name
Ensure that the database name in your connection string is correct and that it matches an existing database on the server.
- Example Query to Check Database Existence:
SELECT name
FROM sys.databases
WHERE name = '<DatabaseName>';
- Replace
<DatabaseName>
with the name of the database you are trying to access. - If the database name does not appear in the results, it might be misspelled, or the database may not exist.
Step 2: Verify Login Credentials
Ensure that the login credentials (username and password) provided in the connection string are correct.
- Check Login Credentials:
- In Azure Portal, navigate to SQL Database > Settings > Connection Strings.
- Verify that the credentials in your application configuration match the required credentials in the portal.
- Example Connection String:
Server=tcp:<YourServerName>.database.windows.net,1433;Database=<DatabaseName>;User ID=<Username>@<ServerName>;Password=<Password>;Encrypt=true;Connection Timeout=30;
Step 3: Grant Appropriate Permissions to the User
If the login exists but lacks sufficient permissions to access the database, grant the necessary access rights.
- Grant Access to Database:
CREATE USER <UserName> FOR LOGIN <LoginName>;
ALTER ROLE db_datareader ADD MEMBER <UserName>;
ALTER ROLE db_datawriter ADD MEMBER <UserName>;
- Replace
<UserName>
with the desired username and<LoginName>
with the login name. - Purpose: Adding the user to
db_datareader
anddb_datawriter
roles grants read and write access to the database.
Step 4: Configure Firewall Rules
Ensure that the client’s IP address is permitted by the Azure SQL Database firewall.
- Steps to Update Firewall Rules:
- In Azure Portal, go to your SQL Server.
- Under Settings, select Firewalls and virtual networks.
- Add the IP address or range of the client.
- Save the changes to apply the firewall rules.
Step 5: Use Azure Active Directory Authentication
If using Azure Active Directory (AD) for authentication, ensure the correct AD roles and permissions are set up, and the AD authentication method is configured correctly in the connection string.
- Example for AD Authentication Connection String:
Server=tcp:<YourServerName>.database.windows.net,1433;Database=<DatabaseName>;Authentication=Active Directory Password;UID=<AADUsername>;PWD=<AADPassword>;
- Replace
<YourServerName>
,<DatabaseName>
,<AADUsername>
, and<AADPassword>
with the appropriate values.
Step 6: Check Database Status and Availability
Sometimes, the database may be unavailable due to maintenance or configuration issues. Check the status of the database in the Azure Portal.
- Steps to Verify Database Status:
- In Azure Portal, navigate to SQL Databases.
- Select your database and check its Status under Overview.
Workarounds
- Verify Database Name: Double-check the database name in the connection string to avoid typos or incorrect names.
- Use Correct Connection Credentials: Confirm the login credentials match what’s required for the target database.
- Use Backups: If the database is temporarily unavailable, consider using a recent backup if read access is required.
Solutions
- Correct Connection String: Ensure that the connection string is configured correctly, including the correct database name, username, and password.
- Firewall Rules: Add the client’s IP address to the firewall settings to allow access.
- Grant Permissions: Create or modify the user’s permissions to enable access to the database.
- Azure Active Directory: If using Azure AD, set up the correct authentication method in the connection string.
Example Scenario
Suppose you encounter Error Code 4060 while trying to connect to an Azure SQL Database.
- Step 1: Run a query to verify the database name:
SELECT name FROM sys.databases WHERE name = '<DatabaseName>';
- The database name is correct.
Step 2: Check login credentials by reviewing the connection string in your application configuration.
Step 3: Grant permissions to the user:
CREATE USER <UserName> FOR LOGIN <LoginName>;
ALTER ROLE db_datareader ADD MEMBER <UserName>;
ALTER ROLE db_datawriter ADD MEMBER <UserName>;
- Step 4: Configure firewall rules in the Azure Portal to include the client’s IP address.
- Step 5: Test the connection again. The database connection should now succeed without Error 4060.
Following these steps should help you diagnose and resolve Error Code 4060, allowing seamless database access.
