i new sql , relational databases, writing code add data tables have created. not sure if code have written correct inserting table. can tell me if correct please.

insert job (job_id, job_name)              values (‘1’, ‘teacher’);

you code right if use autoincrement column job_id should use

and use single quote s , not ‘

insert job ( job_name)          values ( 'teacher');

otherwise code prodivided 

insert job (job_id, job_name)          values ('1', 'teacher );
