Why is my SQL query not running? - mysql

Question

Can someone help me, i don't know why my SQL script wont run? can any one see why?
Here it is
SELECT
vi.`id` as 'VehicleId', vi.`class_type` as 'VehicleClass',vi.`registration_number` as 'VehicleRegistrationNumber',
vr.`role_name` as 'VehicleRole',
vm.`name` as 'VehicleMake',
vmo.`name` as 'VehicleModel',
ud.`name` as 'Depot location',
WHERE vehicle_role = 'High Volume Jet Vac'
FROM
unify_rebuild.vehicle_information as vi
LEFT JOIN
unify_rebuild.vehicle_role as vr
ON
vi.unit_role = vr.role_id
LEFT JOIN
unify_rebuild.vehicle_manufacturer as vm
ON
vi.make = vm.id
LEFT JOIN
unify_rebuild.vehicle_model as vmo
ON
vi.model = vmo.id
LEFT JOIN
unify_rebuild.unify_depot as ud
ON
vi.depot_current_location = ud.id
I am trying to make one master table by joining data into the one so i can then display it on my web app, if anyone can see anything wrong i would greatly appreciate some pointers.

Answer 1

Have you tried to execute your query? I'm pretty sure that you'll receive some interesting errors in order to fix it.
The WHERE clause needs to be at the end of your query (after FROM and the JOINS) and you need to remove the last comma of your SELECT statement.

Answer 2

If you got still error's please check all the column names in your database or use "SELECT *. The where clause is also with the prefix "unify_rebuild." - maybe this helps:
SELECT
vi.id as 'VehicleId',
vi.class_type as 'VehicleClass',
vi.registration_number as 'VehicleRegistrationNumber',
vr.role_name as 'VehicleRole',
vm.name as 'VehicleMake',
vmo.name as 'VehicleModel',
ud.name as 'Depot location'
FROM
unify_rebuild.vehicle_information as vi
LEFT JOIN
unify_rebuild.vehicle_role as vr
ON
vi.unit_role = vr.role_id
LEFT JOIN
unify_rebuild.vehicle_manufacturer as vm
ON
vi.make = vm.id
LEFT JOIN
unify_rebuild.vehicle_model as vmo
ON
vi.model = vmo.id
LEFT JOIN
unify_rebuild.unify_depot as ud
ON
vi.depot_current_location = ud.id
WHERE
unify_rebuild.vehicle_role = 'High Volume Jet Vac'

SELECT vi.id VehicleId
, vi.class_type VehicleClass
, vi.registration_number VehicleRegistrationNumber
, vr.role_name VehicleRole
, vm.name VehicleMake
, vmo.name VehicleModel
, ud.name 'Depot location'
FROM vehicle_information vi
LEFT
JOIN vehicle_role vr
ON vi.unit_role = vr.role_id
AND vr.role_name = 'High Volume Jet Vac'
LEFT
JOIN vehicle_manufacturer vm
ON vi.make = vm.id
LEFT
JOIN vehicle_model vmo
ON vi.model = vmo.id
LEFT
JOIN unify_depot ud
ON vi.depot_current_location = ud.id
