Base Table or View Not Found: 1146 Table ‘example_app.sessions’ Doesn’t Exist? Don’t Panic! Here’s Your Solution

Posted on

If you’re reading this, chances are you’re staring at a dreaded error message that’s got you scratching your head: “Base table or view not found: 1146 Table ‘example_app.sessions’ doesn’t exist”. Don’t worry, it’s not the end of the world! In this article, we’ll dive into the reasons behind this error, and more importantly, provide you with step-by-step instructions to fix it and get your app up and running smoothly.

What’s causing the error?

Before we jump into the solution, let’s quickly understand what’s causing this error. The “Base table or view not found” error occurs when your database can’t find a table or view that your application is trying to access. In this case, the table ‘example_app.sessions’ doesn’t exist, which means that either:

  • The table was never created in the first place.
  • The table was deleted or dropped.
  • There’s a typo or incorrect naming convention in your database schema.
  • Your database connection is pointing to the wrong database or schema.

Step 1: Verify your database connection

Let’s start by ensuring that your database connection is correct. Double-check your database configuration file or settings to ensure that:

  • Database host, username, and password are correct.
  • Database name and schema are correctly specified.

If you’re using a framework like Laravel or Django, make sure you’ve configured your database settings correctly in the respective files (e.g., database.php for Laravel or settings.py for Django).


<?php
return [
    'default' => env('DB_CONNECTION', 'mysql'),
    'connections' => [
        'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', 'localhost'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'example_app'),
            'username' => env('DB_USERNAME', 'root'),
            'password' => env('DB_PASSWORD', ''),
        ],
    ],
];
</?>

Step 2: Check your database schema

Next, let’s investigate your database schema to ensure that the table ‘example_app.sessions’ exists or can be created:

  1. Log in to your database management system (e.g., phpMyAdmin, MySQL Workbench, etc.).
  2. Navigate to your database schema (e.g., ‘example_app’).
  3. Check if the table ‘sessions’ exists in the schema. If it doesn’t, proceed to the next step.

If the table doesn’t exist, you can either create it manually using SQL or run the necessary migration commands to create it.


CREATE TABLE sessions (
  id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  user_id INT(6) UNSIGNED,
  session_data TEXT,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

Step 3: Run database migrations (if applicable)

If you’re using a framework that supports database migrations (e.g., Laravel, Django), run the necessary migration commands to create the ‘sessions’ table:


php artisan migrate

This command will execute the pending migrations and create the required tables, including the ‘sessions’ table.

Step 4: Verify table permissions

Ensure that your application has the necessary permissions to access the ‘sessions’ table:

  1. Check the table permissions using the following SQL command:
SHOW GRANTS FOR 'your_username'@'your_host';

This command will display the privileges associated with your database username and host. Make sure the username has the necessary permissions to SELECT, INSERT, UPDATE, and DELETE records from the ‘sessions’ table.

Step 5: Update your application code

If you’ve reached this point, it’s likely that your application code is trying to access the ‘sessions’ table before it’s created or before the database connection is established. Update your code to:

  1. Delay the access to the ‘sessions’ table until the database connection is established.
  2. Use a try-catch block to handle the error and create the table or skip the operation if it doesn’t exist.
// Example code snippet
try {
    $ sessions = Session::all();
} catch (\Exception $e) {
    if ($e->getCode() === 1146) {
        // Create the sessions table or handle the error according to your app's logic
    } else {
        // Handle other exceptions
    }
}

Conclusion

By following these steps, you should be able to resolve the “Base table or view not found: 1146 Table ‘example_app.sessions’ doesn’t exist” error and get your application up and running smoothly. Remember to:

  • Verify your database connection and schema.
  • Create the required tables or run database migrations.
  • Ensure necessary permissions for your application.
  • Update your application code to handle errors and exceptions.

Don’t let this error hold you back! With these steps, you’ll be well on your way to fixing the issue and getting your app back on track.
