How to Select the Row with the Highest ID in a Database Table?

Selecting a Row with the Highest ID in a Table

The question presents a need to retrieve a row from a table that holds the maximum ID value. To address this, one approach revolves around utilizing a subquery. By embedding a subquery that calculates the maximum ID within a larger query, it becomes possible to filter the table and select only rows that match this maximum ID criteria.

Syntax for this approach:

SELECT row 
FROM table 
WHERE>

It's noteworthy that when employing this method, multiple rows may be returned if the maximum ID value is not unique. However, if the goal is to retrieve just one such row, an alternative approach is available:

SELECT row from table ORDER BY id DESC LIMIT 1

This method arranges the table in descending order based on ID values and retrieves the first row, which effectively represents the row with the highest ID.
