    CREATE TABLE [dbo].[STUDENT]
    (
         STUDENT_ID  int not null Identity,
         SCHOOL_ID INT NOT NULL,
         CONSTRAINT PKEY PRIMARY KEY (STUDENT_ID),
         CONSTRAINT FKEY FOREIGN KEY (USER_ID)  REFERENCES USER (USER_ID)

     );

it gives me and sql80001 error please help

Answer 1

USER is a reserved keyword in SQL Server . Use [] to escape the name

CREATE TABLE [dbo].[STUDENT]
(
     STUDENT_ID  int not null Identity,
     SCHOOL_ID INT NOT NULL,
     CONSTRAINT PKEY PRIMARY KEY (STUDENT_ID),
     CONSTRAINT FKEY FOREIGN KEY (USER_ID)  REFERENCES [USER] (USER_ID)
)
