I have never "hand-coded" object creation code for SQL Server and foreign key decleration is seemingly different between SQL Server and Postgres. Here is my sql so far:
drop table exams; drop table question_bank; drop table anwser_bank; create table exams ( exam_id uniqueidentifier primary key, exam_name varchar(50), ); create table question_bank ( question_id uniqueidentifier primary key, question_exam_id uniqueidentifier not null, question_text varchar(1024) not null, question_point_value decimal, constraint question_exam_id foreign key references exams(exam_id) ); create table anwser_bank ( anwser_id uniqueidentifier primary key, anwser_question_id uniqueidentifier, anwser_text varchar(1024), anwser_is_correct bit );
When I run the query I get this error:
Msg 8139, Level 16, State 0, Line 9 Number of referencing columns in foreign key differs from number of referenced columns, table question_bank .
Can you spot the error?
