Hey folks, I need your help. I stuck with my Database project.
I have five tables on the database: These are

Room, Guest, Booking, Employee and Admin

Room (room_ no, room_ type, price)
Guest (guest_ no, Fname, Sname, address,…)
Booking (room_no, guest_no, Fname, Sname, arrival_date,
departure_date, emp_no, user_name, password)
Employee (emp_no, Fname, Sname, uaser_name, password)
Admin (admin_no, fname, Lname, user_name, password)

I used the fallowing query to search for available rooms:

Select *
From Room R
Where R.room_no
NOT IN (Select B.room_no
From R.room_no = B.room_no
And R.room_type = ‘single’
And B.arrival_date = ‘2005-03-16’
And Bdeparture_date = ‘2005-04-19’

Q1. Whenever I do a query on localhost it retrieves a value, but when I try on live it shows an error. Please, tell me what the problem in this query could be?

Q2. Does MySQL use different SQL query such as like PL SQL or is it the similar query?

Q3.Is their any simple query than this.

Thanks for all your help.
