Insert into table with a foreign key

问题

Using Postgresql

Customer

Nmb_id | Order History | Search |

Contacts

Primary_Key | Nmb_id_fk | Fax | Email | 

Nmb_id_fk is a foreign key to the Customer primary key Nmb_id.

Trying to insert data into a table with a FK relationship:

SQL:

insert into contacts (fax, email, Nmb_id_fk) 
values( '123', 'a@a.com', (select "Nmb_id" from customer where "Nmd_id" = 4));

Keep getting error:

ERROR: column "Nmb_id_fk" of relation "contacts" does not exist

回答1:

insert into contacts (fax, email, "Nmb_id_fk") 
select '123', 'a@a.com', c."Nmb_id" 
from customer c 
where c."Nmd_id" = 4;
