SQL Query Report Writing

Question

I provided the ERD showing all the Tables and their info. How would I go about writing an SQL query for this report? Let me know if any other details are needed or if the ERD is sufficient.

Thanks!

Answer 1

SELECT date(s.showtime) as date
    , s.showtime
    , c.channelnumber
    , p.progname
    , p.proglength 
    , su.suppliername
FROM program as p left join schedule as s on p.progid = s.programid 
left join channel as c on s.channelid = c.channelid 
left join supplier as su on p.supplierid = su.supplierid 

your schedule table has many pk and your structure is not according to normalized form. better restructure it thanks
