This is the code for Getting all the channel_ids that uploaded at least one video in "AI/ML" or "Robotics" technologies between 2018 and 2021.
SELECT
DISTINCT channel_id
FROM
video
WHERE
video_id >= 1
AND name LIKE '%AI/ML%'
OR name LIKE '%Robotics%'
AND strftime('%Y', published_datetime) BETWEEN "2018"
AND "2021"
GROUP BY
channel_id
ORDER BY
channel_id ASC;
Output Table:
channel_id 351 353 364 365 377
But,
How can I Get all the channel_ids that uploaded at least 20 videos in "AI/ML", "Cyber Security", "Data Science" or "Robotics" technologies between 2018 and 2021.
Example: If a channel publishes 5 videos in AI/ML, 10 videos in Cyber Security and 5 videos in Data Science, consider the channel
the table data is very huge so, I cant send the complete table data.
please help me.
A weight A pound on one side of a beam balances a weight of 40 pounds placed 6 feet from the fulcrum on the other side. If the unknow weight is moved 3 feet nearer the fulcrum, it balances a weight of 20 pounds place 7 1/2 feet from the fulcrum. Find the unknow weight and its distance from the fulcrum in the first instance. (Neglect the weight of the beam.)
