Sql не может создать таблицу без правой скобки

Question

Я создал таблицу employee и Salaire. Но я получаю ошибку при создании таблицы Zone:

00907-0000 отсутствует правая скобка

Код:

Create table Employee 
(
    CodeEmploye int,
    NAS Number (9),
    Nom Varchar(20) not null,
    Prenom Varchar(20) not null,
    NomJeuneFille varchar(20) not null,
    DateNaissance Date,   
    Adresse varchar(100) not null,
    Sexe Char(1),
    Telephone Varchar(14),
    Fonction Varchar(20) not null,
    Service varchar(13) not null,
    Taux Number(6,2) default (0),
    Grade Varchar(2),

    Constraint PK_Employe Primary key (CodeEmployee),
    Constraint NAS_Employe Unique (NAS),
    Constraint Verfi_Sexe Check Sexe IN ('F', 'M'),
    Constraint verif_Service Check Service IN ('adminstratif', 'surveillance', 'medical'),   
    Constraint verfi_Grade Check grade in ('G1', 'G2','G3', 'G4', 'G5')
);

Create Table Salaire
(
    CodeEmployee int, 
    Mois int,     
    Salaire Number(11,2) default (0),

    Constraint PK__Salaire Primary key (CodeEmployee, Mois),
    Constraint verif_Mois Check Mois between 1 and 12,
    Constraint FK_Salaire_Employe Foreign Key (CodeEmploye) references Employee(CodeEmployee) 
);

Create Table Zone
(
    CodeZone int,
    NomZone Varchar(20), not null 
    ChefZone Varchar(20),     

    Constraint PK_Zone Primary Key (CodeZone),
    Constraint FK_Zone_Employee Foreign Key (ChefZone) references Employee(Taux, Grade) On delete set null on update cascade

Answer 1

вам нужно добавить скобки после проверки

Create table Employe (
CodeEmploye int,
NAS Number (9),
Nom Varchar(20) not null,
Prenom Varchar(20) not null,
NomJeuneFille varchar(20) not null,
DateNaissance Date,   
Adresse varchar(100) not null,
Sexe Char(1),
Telephone Varchar(14),
Fonction Varchar(20) not null,
Service varchar(30) not null,
Taux Number(6,2) default 0,
Grade Varchar(2),
Constraint PK_Employe Primary key (CodeEmploye),
CONSTRAINT NAS_Employe Unique  (NAS),
Constraint Verfi_Sexe Check (Sexe IN ('F', 'M')),
Constraint verif_Service Check ( Service IN ('adminstratif', 'surveillance', 'medical')),   
Constraint verfi_Grade Check (grade in ('G1', 'G2','G3', 'G4', 'G5'))
);

Create Table Salaire(
CodeEmploye int, 
Mois int,     
Salaire Number(11,2) default (0),
Constraint PK__Salaire Primary key (CodeEmploye, Mois),
Constraint verif_Mois Check (Mois between 1 and 12),
Constraint FK_Salaire_Employe Foreign Key (CodeEmploye) references Employe(CodeEmploye));

и для 3-й таблицы вам нужно исправить определение ключа foregin
