How to Fix the \"Access Denied\" Error for MySQL Users?

"Access Denied" Error for MySQL User

This error typically occurs when a MySQL user lacks the necessary permissions to access a specific database. Here's how to resolve it:

1. Grant Privileges:

As mentioned in the answer, you need to grant privileges to the user who is attempting to access the database. To do this, use the following command:

<code class="sql">GRANT ALL PRIVILEGES ON `<database_name>`.* TO `<username>`@'localhost';</code>

Replace with the name of the database you want to grant access to, and with the username of the user who should have access.

2. Flush Privileges:

After granting privileges, it's crucial to flush them so they take effect. Run this command:

<code class="sql">FLUSH PRIVILEGES;</code>

3. Proper Database Selection:

In your PHP code, ensure you use the correct database name when connecting to MySQL:

<code class="php">mysql_select_db($dbname);</code>

Make sure that $dbname matches the database you granted access to in step 1. If the database name is empty, MySQL will default to the associated database for the user, which might not be the intended one.
