How to Import a CSV File into MySQL with Different Column Names

In this article, we'll guide you through importing a CSV file into a MySQL table, even when the column names differ.

To facilitate this process, you can use a query that includes the LOAD DATA INFILE syntax. This approach allows you to specify which CSV column will be imported into which database column, even if the names are different.

Syntax

LOAD DATA INFILE 'csv_file_path' INTO TABLE table_name (column_name1, column_name2, ...);
Copy after login

Example

Assuming you have a CSV file named data.csv with the following data:

<code class="csv">uniq_name,uniq_city,uniq_comment
John Doe,New York,This is John's comment
Jane Smith,Los Angeles,This is Jane's comment</code>
Copy after login

And a MySQL table named my_table with the following columns:

id,name,city,comments
Copy after login

You can use the following query to import the CSV data into the my_table table, mapping the columns accordingly:

<code class="sql">LOAD DATA INFILE 'data.csv' INTO TABLE my_table (id, name, city, comments);</code>
Copy after login

Additional Notes

  • Make sure that the CSV file path is correct and accessible.
  • Ensure that the data types in the CSV file match the corresponding columns in the database table.
  • You can use the INTO IGNORE clause to ignore duplicate records.
  • If you encounter any issues during the import process, review the MySQL documentation for additional troubleshooting tips.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
