Hi
I have a question regarding foreign keys, I just cannot get it to create
them for me....I must be doing something wrong but I have no idea what
that might be :)
I have a table "clients"
clientID (primary)
ticode
Firstname
SecondName
I have a second table "titles"
ticode (primary)
Title
I am trying to create a foreign key on TIcode "clients" table as in below,
ALTER TABLE clients ADD CONSTRAINT the_title FOREIGN KEY (ticode)
REFERENCES titles (ticode) ;
I keep getting this error
ERROR: insert or update on table "clients" violates foreign key
constraint "the_title"
DETAIL: Key (ticode)=( ) is not present in table "titles".
Sorry, I have no idea where I am going wrong...Any help would be great
TIA
C
