How to Find Matching Max Video IDs with URLs, Dates,

Finding Corresponding Max Values in SQL

You're attempting to retrieve specific values from your "videos" table, where each category's maximum video ID should correspond to the matching URL, date, title, and description. However, your query is currently selecting the first row for these values instead of those associated with the maximum video ID.

To resolve this issue and ensure that the values for different columns align with the maximum video ID for each category, you can use a SQL query like the following:

SELECT
    *
FROM
    videos v
WHERE
    v.video_id IN (
        SELECT
            DISTINCT
            MAX(video_id)
        FROM
            videos
        GROUP BY
            video_category
    ) 
ORDER BY
    v.video_category ASC

This updated query guarantees that the values for URL, date, title, and description correspond to the maximum video ID for each category. It uses a subquery to identify the maximum video ID for each category, and then filters the main query to retrieve the matching rows.

Alternatively, you could also use the following query:

SELECT
    *
FROM
    videos s
JOIN
    (SELECT MAX(video_id) AS id FROM videos GROUP BY video_category) max
    ON s.video_id = max.id

This query uses a join to filter the "videos" table based on the maximum video ID for each category, ensuring that the selected rows have corresponding values for URL, date, title, and description aligned with the maximum video ID.
