How to Retrieve the Row with the Maximum ID from a Database Table?

Retrieving the Row with the Maximum ID

In a database table, selecting the row with the largest ID can be a useful operation. Suppose you have a table named table with a column named id that uniquely identifies each row. To retrieve the entire row with the highest id value, you can employ the following approaches:

Using a Subselect:

This method involves using a subselect to determine the maximum id value and then filter the table to select the corresponding row:

SELECT row 
FROM table 
WHERE>

Note that if multiple rows have the same maximum id, this subquery will return all those rows.

Using a Single Query:

If you only need a single row with the maximum id, you can use the following query:

SELECT row 
FROM table 
ORDER BY id DESC 
LIMIT 1

This query retrieves the rows in descending order of id and limits the result to the top row, which will be the one with the maximum id value.
