How to fix an SQL design - sql

Question

I'm doing the study of a medical software. This software asks the patients questions about their symptoms and from them it can determine the possible pathologies. My study involves comparing the symptoms and pathologies found by the software with those from the hospital.
In order to make my work easier, I decided to enter the data in a database made with javadb on netbeans 8.2.
But it seems like that I did something wrong since my statement doesn't work.
I thank you in advance anybody who would take the time to help me.
SQL design:
Create table Patients(
nip varchar(32) primary key,
sexe varchar(8) not null,
age int not null,
dateArrivee timestamp not null,
constraint ck_sexe check(sexe='Male' or sexe='Female'),
constraint ck_age check (age>=0)
);
Create table Symptoms(
symptomID int primary key generated always as identity (start with 1,
increment by 1),
nip varchar(32) not null,
symptom varchar(64),
origin varchar(16) not null,
foreign key (nip) references Patients(nip),
constraint ck_origin check (origin='SOFTWARE' or origin='HOSPITAL')
);
Create table Pathologies(
pathologyID int primary key generated always as identity (start with 1,
increment by 1),
nip varchar(32) not null,
pathology varchar(64),
origin varchar(16) not null,
foreign key (nip) references Patients(nip),
constraint ck_origin check (origin='SOFTWARE' or origin='HOSPITAL')
);
Values entered:
Insert into Patients values ('001','Male', 25, '2019-05-27 14:00:00');
Insert into Patients values ('002', 'Female', 30, '2019-05-26 15:00:00');
Insert into Symptoms values (, '001', 'Headache', 'SOFTWARE');
Insert into Pathologies values (,'001', 'Fever', 'SOFTWARE');
Insert into Symptoms values (,'001', 'Stomache', 'HOSTPITAL');
Insert into Pathologies values (, '001', 'Gastro-enteritis', 'HOSPITAL');
Insert into Symptoms values(,'002', 'Headache', 'SOFTWARE');
Insert into Pathologies values (,'002', 'Unknow', 'SOFTWARE');
SQL statement:
Select *
from (Patients inner join
Symptoms
on Patients.nip = Symptoms.nip
) inner join
Pathologies
on Symptoms.nip = Pathologies.nip
where Symptoms.origin = 'MEDVIR' and
Pathologies.origin = 'MEDVIR';
So sorry I forgot to put the errors I'm getting.
SQL design:
First I have an error concerning the auto_incrementation, even thought this was the good method. It says that the syntax is incorrect near the 'generated'.
Values entered:
Here I have an error concerning the a wrong syntax near the coma (',').
SQL statement:
Lastly I have an error saying that the object 'Patients' is unavaible.

Answer 1

If I am not wrong, you are trying to fetch entries where 'Origin' = 'MEDVIR'
Although, none of your insert statements have Origin as 'MEDVIR'
Please check below,
Select *
from (Patients inner join
Symptoms
on Patients.nip = Symptoms.nip
) inner join
Pathologies
on Symptoms.nip = Pathologies.nip
where Symptoms.origin IN ('SOFTWARE', 'HOSPITAL') and
Pathologies.origin IN ('SOFTWARE', 'HOSPITAL');
Also, some of your INSERT statement has an extra comma before the values, which would cause a syntax error.
