I have a added a new column bill_cycle in Coaching_class_entries table and I have the same column bill_cycle in another table called Coaching_classes . Now I want to copy the values of bill_cycle from Coaching_classes to Coaching_class_entries bill_cycle column for all the rows of coaching_class_entries. I am very new to database can anyone give me some hint please.
I think a simple update join should work here:
UPDATE Coaching_class_entries t1
INNER JOIN Coaching_classes t2
ON t1.coaching_class_id = t2.id
SET t1.bill_cycle = t2.bill_cycle;

I want to be able to select classes that are starting on or after the next two hours up until the end of tomorrow's date but I am not sure of how to do this.
My current sql is below, I have only been able to select classes that are after today's date and after the current time. I want to be able to only return classes that start two hours after now up until the end of tomorrows date.
I am able to pass the current date and current time into my node.js function that will construct the sql statement. Also, I have access to moment.js library if I need to use this I could.
Any help would be appreciated.

phpMyAdmin automatically adds a LIMIT clause to the query. Because you do not have an ODER BY clause, MySQL sends the results as soon as it has found the number of records that you requested in the LIMIT clause.
Add a LIMIT clause to the query that you execute on the command line.

try this. it may works properly...

,p.account_id AS account.id
,acsub.subscription_id as subscription.id
FROM Person AS p
LEFT JOIN Account-Subscription AS acsub ON p.account_id=acsub.account_id

Here is the deal. I have two tables

+----------------+------------------+------+-----+---------+----------------+
And the question is:
How can I select all the tracks and the date that has maximum visits for every specific track?
Regards
Nasko
Since you are using MySql, you can use this:
SELECT tracks.*, track_visits.*
FROM
tracks LEFT JOIN (
SELECT track_id, MAX(created_at) MaxCreatedAt
FROM track_visits
GROUP BY track_id) mx
ON tracks.track_id=mx.track_id
LEFT JOIN track_visits
ON mx.track_id=track_visits.track_id
AND mx.MaxCreatedAt=track_visits.created_at
GROUP BY
tracks.track_id
