Hello, I am trying to run my tables in the Sql Workshop using the Sql Commands option in Oracle, and I get this error - "ORA-00922: missing or invalid option". I read that this is somehow related to the NOT NULL option, but I think this is how my table should look like, and it still gives me an error. So, would you, please, take a look at it.
CREATE TABLE Izraboteni proekti (
Primaren_broj NUMERIC(30) NOT NULL ,
Kandidat_ID NUMERIC(30) NOT NULL ,
Tema VARCHAR(255) ,
Ocena NUMERIC(30) ,
PRIMARY KEY(Primaren_broj, Kandidat_ID),
FOREIGN KEY(Kandidat_ID)
REFERENCES Kandidat(Kandidat_ID));
