Data too long for column

❌ Error​

Data too long for column 'xyz' at row 1

📍 Context​

This error occurs when an inserted or updated value is larger than the defined column size (e.g., trying to insert 300 characters into a VARCHAR(100)).

✅ Solution​

  • Increase the column length:
    ALTER TABLE table_name MODIFY COLUMN xyz VARCHAR(512);
  • Ensure your script does not insert oversized values.
  • Validate data before inserting into the database.

ℹ️ Additional Information​

  • Review default values in your scripts.
  • Consider using TEXT or LONGTEXT for larger strings.
  • For more details, refer to the MySQL documentation.
