Why Does MySQL Throw a \'Table Doesn\'t Exist\' Error Despite Correct SQL Code?

Table Existence Conundrum: Understanding Error #1146 in MySQL

When creating a table in phpMyAdmin using its built-in feature, you may encounter the frustrating error #1146: Table 'ddd.mwrevision' doesn't exist, even though the SQL code generated looks correct.

The Problem

This error often occurs after you encounter issues with the database files, particularly those related to the InnoDB storage engine. When InnoDB tables are moved or the MySQL server is updated, these tables can become inaccessible and lead to the existence error.

Solution

To resolve this issue and regain access to your InnoDB tables, you should consider the following steps:

• Recreate the Database: Create a new database with the same name as the affected one.
• Restart MySQL Service: Stop and restart the MySQL service to refresh the database and storage engine.

Understanding InnoDB Table Binaries

InnoDB tables are stored in binary files, which contain both the table structure and data. When you move or edit these files, it's crucial to ensure that the MySQL server is aware of the changes. The recreation of the database and restarting of the MySQL service enforce this awareness and allow the affected tables to be recognized again.
