Navigating the Unusual MySQL Error 1003 (ER_YES): Diagnosis and Solutions

When working with MySQL, encountering Error 1003 with the SQLSTATE HY000 and the message “YES” can be quite perplexing. This error message is not a typical one and can leave many developers scratching their heads. The message “YES” associated with Error 1003 is not an error in the conventional sense but rather an internal message that MySQL uses, which is not expected to be seen by users.

Understanding Error 1003 – SQLSTATE: HY000 (ER_YES)

Error 1003 is an unusual message that you would not typically encounter during normal MySQL operations. It is, in essence, a placeholder or a test message within the MySQL source code. According to the MySQL Server Error Codes and Messages documentation, this error code is accompanied by a simple message “YES,” which does not provide any indication of what might be wrong.

Diagnosing the Issue

Since Error 1003 is not intended to be an actual error message for end-users, its appearance is highly unusual. If you do encounter this message, it may be due to a rare bug or a situation where MySQL’s internal state has produced an unexpected result. To diagnose this issue, consider the following steps:

  1. Check the MySQL error log for any additional context or messages that might accompany Error 1003.
  2. Review the query or operation that led to the error message to ensure it is syntactically correct and logical.
  3. Look for any triggers, stored procedures, or user-defined functions that might be interacting in unexpected ways.

Fixing the Error

Given the nature of Error 1003 as an internal test message, there is no direct fix or solution. However, you can take the following general troubleshooting steps:

Example 1: Restarting the MySQL Service

Sometimes, simply restarting the MySQL service can resolve transient issues:

sudo service mysql restart

Example 2: Upgrading MySQL

If you are using an older version of MySQL, consider upgrading to the latest stable release, as the issue might have been resolved in a newer version:

sudo apt-get update
sudo apt-get install mysql-server

Example 3: Checking for Bugs

Search the MySQL bug tracker or forums to see if other users have reported this issue and if there is a known bug or resolution.

Example 4: Contacting Support

If the error persists and you cannot find a solution, consider reaching out to MySQL support or community forums for assistance.


Error 1003 in MySQL with the message “YES” is an anomaly and not something you would typically need to address. If this message does appear, it’s likely indicative of a deeper issue that may require support from MySQL professionals or a review of the system’s configuration and code. Always ensure your systems are up-to-date and regularly backed up to mitigate any potential impact from such rare occurrences.
