How to add condition in mySQL statement - mysql

Question

I'm trying to add a condition in my mySQL statement where if the status is >= 6 then it only shlows the dates between fit_appointment_start_date and if the status is <= 5 then it uses the appointment_start_date condition instead. Is there a way to do this in Mysql?
At the moment i'm just doing an (and or) which is bringing back all the records in the condition, but i need it to change the condition depending on the status
This is my SQL.
SELECT j.client_first_name,
u.home_postcode,
j.engineer_id,
j.deposit_taken,
j.men,
j.time_taken,
j.potential_instalation_date,
j.id,
j.status,
j.postcode,
j.calendar_notes,
j.hasinvoice,
u.color,
j.fit_appointment_start_date,
j.fit_appointment_end_date,
j.client_surname,
j.appointment_start_date,
j.appointment_end_date,
u.username AS engineer_username,
j.potential_instalation_notes
FROM jobs j
INNER JOIN users u
ON u.id = j.engineer_id
INNER JOIN status s
ON s.id = j.status
WHERE u.active = 1
AND ( j.fit_appointment_start_date BETWEEN
'2021-05-04 00:00:00' AND '2021-05-04 23:59:59'
OR j.appointment_start_date BETWEEN
'2021-05-04 00:00:00' AND '2021-05-04 23:59:59' )
ORDER BY engineer_username

Answer 1

if the status is >= 6 then it only shlows the dates between fit_appointment_start_date and if the status is <= 5 then it uses the appointment_start_date condition instead.
...
AND CASE WHEN status >= 6
THEN j.fit_appointment_start_date BETWEEN
'2021-05-04 00:00:00' AND '2021-05-04 23:59:59'
WHEN status <= 5
THEN j.appointment_start_date BETWEEN
'2021-05-04 00:00:00' AND '2021-05-04 23:59:59'
END
...
PS. The rows with status IS NULL won't be selected.
