How Can I Retrieve Only Unique Dates from a MySQL Table?

Eliminating Duplicate Values from a Column: A Comprehensive Approach

When accessing data from a database, encountering duplicate values can be an issue. In the context of a MySQL table containing dates, it may be desirable to display only unique dates. This can aid in data analysis or presentation by avoiding redundant entries.

To address this, the DISTINCT operator provides an effective solution. By modifying the original script, we can incorporate DISTINCT as follows:

$sql = mysql_query("SELECT DISTINCT(Date) AS Date FROM buy ORDER BY Date DESC");

The DISTINCT operator ensures that only unique values for the Date column are retrieved. This results in the desired output:

12.dec.2011
10.dec.2011

By excluding duplicates, the script now displays a concise list of unique dates from the database table. This refined approach improves both data clarity and efficiency.
