How to Convert Unix Timestamps to Human-Readable Dates in MySQL?

Humanizing Unix Timestamps with MySQL's FROM_UNIXTIME() Function

Question:

How can I convert Unix timestamps, stored in a MySQL database field, into human-readable date formats?

Answer:

To efficiently convert Unix timestamps into a user-friendly format within MySQL, leverage the built-in FROM_UNIXTIME() function. This powerful function allows you to transform timestamp values into human-readable date formats.

Syntax:

SELECT
  FROM_UNIXTIME(timestamp) 
FROM 
  your_table;

Example:

Suppose you have a field named timestamp that stores Unix timestamps. To retrieve the corresponding human-readable dates, execute the following query:

SELECT
  FROM_UNIXTIME(`timestamp`) AS formatted_date 
FROM 
  your_table;

This query returns a new column named formatted_date that contains the humanized dates.

Additional Information:

  • The FROM_UNIXTIME() function supports various date formatting options. By using format specifiers, you can customize the output date format. For more details, refer to the MySQL documentation on FROM_UNIXTIME().
  • This function is incredibly versatile and can be employed in various scenarios, such as displaying timestamps in chronological order, filtering records based on date ranges, and performing date-related calculations.

When should you use a composite index versus multiple single-column indexes?When should you use a composite index versus multiple single-column indexes?Apr 11, 2025 am 12:06 AM

In database optimization, indexing strategies should be selected according to query requirements: 1. When the query involves multiple columns and the order of conditions is fixed, use composite indexes; 2. When the query involves multiple columns but the order of conditions is not fixed, use multiple single-column indexes. Composite indexes are suitable for optimizing multi-column queries, while single-column indexes are suitable for single-column queries.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
