Retrieve the maximum value in a specific field from a MySQL query.

You can use the following MySQL query to find the row with the maximum value in a certain field:

SELECT * FROM your_table ORDER BY your_field DESC LIMIT 1;

The above query will sort the results in descending order based on the field you specify (your_field), and then use LIMIT 1 to return only one row, which is the highest one. Please replace your_table with your table name and your_field with the field you want to search for.
