    mysql tutorial for data import from CSV
    The key to importing CSV data to MySQL is to make sure the format is correct and use the appropriate commands. First, confirm that the CSV file path is accessible to MySQL, and that the field structure of the target table matches the CSV column; second, it is recommended to use the LOADDATAINFILE command to import, pay attention to setting correct field separators, line breaks, and skipping title lines. In addition, if you are not familiar with SQL operations, you can complete the import through graphic tools such as phpMyAdmin or Navicat; finally, when dealing with common problems, you need to check whether the number of fields is consistent, whether the file encoding is UTF-8, whether the user has FILE permissions, and whether the file path is valid. Follow these steps and the CSV import process will be smoother.
