SQL でクエリを記述する方法がわかりません。

これが私のテーブルです。

CREATE TABLE offences (
oOffenceID VARCHAR (30),
oDescription VARCHAR (200),
oMaximumFine INT (10),
CONSTRAINT o_pk
PRIMARY KEY (oOffenceID)
);

CREATE TABLE drivers (
dPersonID VARCHAR (30),
dLicenseNumber INT (20),
dLicenseRemoved ENUM('yes','no'),
dExpiryDate DATE,
CONSTRAINT d_pk
PRIMARY KEY (dLicenseNumber),
CONSTRAINT d_fk
FOREIGN KEY (dPersonId)
REFERENCES People (pPersonID)
);

CREATE TABLE people (
pPersonID VARCHAR (30),
pName VARCHAR (30),
pAddress VARCHAR (50),
pNIN VARCHAR (30),
CONSTRAINT p_pk
PRIMARY KEY (pPersonID)
);

CREATE TABLE vehicle (
vOwnerID VARCHAR (30),
vColour VARCHAR (30),
vModel VARCHAR (30),
vMake VARCHAR (30),
vVehicleID VARCHAR (30),
CONSTRAINT v_pk
PRIMARY KEY (vVehicleID),
CONSTRAINT v_fk
FOREIGN KEY (vOwnerID)
REFERENCES People (pPersonID)
);

CREATE TABLE fines (
fFineID INT (30) AUTO_INCREMENT,
fVehicleID VARCHAR (30),
fPersonID VARCHAR (30),
fTime DATE,
fAmount INT (10),
fOfficerStatement VARCHAR (500),
fOffenceID VARCHAR (30),
CONSTRAINT f_pk
PRIMARY KEY (fFineID),
CONSTRAINT f_fk
FOREIGN KEY (fVehicleID)
REFERENCES vehicle (vVehicleID),
CONSTRAINT f_fk1
FOREIGN KEY (fPersonID)
REFERENCES people (pPersonID),
CONSTRAINT f_fk2
FOREIGN KEY (fOffenceID)
REFERENCES offences (oOffenceID)
);

車の VehicleID、所有者の名前、および 1000 を超える罰金を累積したすべての自動車の累積罰金の合計額を表示するクエリが必要です。誰でもそれを行う方法を見ることができますか?

Select a.vVehicleID,
       b.pName,
       sum(d.fAmount) fine 
from vehicle a,people b,fines d,drivers e 
where a.vVehicleID=d.vVehicleID and d.fPersonID=e.dPersonID and d.fPersonID=a.vOwnerID and
      b.pPersonID = e.dPersonID 
group by a.vVehicleID,b.pNamem
having fine > 1000;

これはうまくいくはずです
