"Tables Missing" Error
Databases created manually through the MySQL Databases section in cPanel are initially empty, meaning they do not contain any tables. This error may appear when executing a search query within the database.
Error Message:
Tables missing. No tables found in the database!
Please ensure that the target database contains tables.
How to Fix:
- Import data into the database.
- If the database has tables but they are not visible, try refreshing the page.
- Alternatively, navigate to the Structure tab of the selected database and click Browse under the Action column to view the tables.
"Table is Full" Error
Error Message:
1114 (HY000) at line 1234: The table "abc" is full.
This error can occur due to several reasons, including:
- The database reaching its storage limit.
- Insufficient disk space.
- Database server configuration restrictions.
How to Fix:
- Check and free up disk space – Ensure the server has enough storage available.
- Adjust SQL server settings – Modify database configurations to increase table size limits.
- Recreate indexes – Rebuilding indexes can optimize space usage and improve performance.
Error 2002: Server Not Responding
Error Message:
#2002 - The server is not responding (or the local MySQL server's socket is not correctly configured).
Causes:
- The MySQL server is down or unresponsive.
- The socket file is incorrectly configured.
How to Fix:
To resolve this issue, restart the MySQL server. If you do not have root access, contact your hosting provider for assistance via support or live chat.
Error Code 1064: SQL Syntax Error
Error Message:
Error Code 1064 (42000): You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near ____.
Cause:
This error occurs when the SQL query contains incorrect syntax. The most common issues include:
- Improper use of quotation marks (single ', double ").
- Incorrect backticks (`) around table or column names.
- Missing or misplaced keywords in the SQL statement.
How to Fix:
- Review the SQL query and ensure proper use of single quotes ('), double quotes ("), and backticks (`).
- Cross-check the syntax against your MySQL version’s manual.
- If unsure, run small sections of the query separately to identify the problematic part.
Error Code 2013: Lost Connection to MySQL Server During Query
Error Message:
Error Code 2013: Lost connection to MySQL server during query.
Cause:
This error occurs when the connection between the MySQL client and the database server times out. It usually happens when:
- A query takes too long to execute.
- The server’s timeout settings are too low.
How to Fix:
- Increase the timeout values in the MySQL server configuration (wait_timeout and max_allowed_packet).
- Optimize your SQL queries to reduce execution time.
- Check server performance to ensure it can handle the query load.
Error: Packet Too Large
Error Message:
ERROR: Packet too large
Cause:
This error typically appears alongside Error Code 2013: Lost Connection to MySQL Server During Query and occurs when a query attempts to send data that exceeds the server’s allowed packet size.
How to Fix:
- Increase the max_allowed_packet value in the MySQL configuration file (my.cnf or my.ini).
- Set it to a size that matches or exceeds the largest BLOB field used in your database.
- Restart the MySQL server for the changes to take effect.
MySQL Can't Create/Write to File Error
Error Message:
MySQL can't create/write to file
Cause:
This error occurs when MySQL is unable to create a temporary file for the result set in the temporary directory (tmpdir). Common reasons include:
- Insufficient permissions on the tmpdir directory.
- The temporary directory does not exist.
- The file system is full, preventing MySQL from writing new files.
How to Fix:
- Check and adjust file permissions for the tmpdir directory.
- Ensure the directory exists and is correctly set in MySQL’s configuration.
- Free up disk space if the file system is full.
phpMyAdmin Showing Login Screen
Issue:
If clicking on the phpMyAdmin button in cPanel redirects you to a login page, it indicates that your MySQL and cPanel passwords are not synchronized.
How to Fix:
To resolve this, simply change your cPanel password. This will sync it with your MySQL password, allowing you to log in to phpMyAdmin without issues.
