Hello
Given you have a date column, you can use it to determine the latest row. However, there is still a chance that two rows were inserted at exactly the same time in which case you will need something in addition to your date column to decide which is the latest...
The first option uses a sub query and the second uses analytics, as does the 3rd - however with the 3rd, if 2 rows have exactly the same date and time, it will pick one at random unless you include another column in the order by to determine the latest...
select
FROM
    your_table
WHERE
    your_date_column = (SELECT MAX(your_date_column) from your_table)
SELECT
FROM
        select
            a.*,
            MAX(your_date_column) OVER() max_date_column
        FROM
            your_table a
WHERE
    your_date_column = max_date_column
SELECT
FROM
        select
            a.*,
            ROW_NUMBER OVER(ORDER BY your_date_column DESC) rn
        FROM
            your_table a
WHERE
    rn = 1HTH
