An immediate question: did you check that Key (docuuserid)=(8415) is actually present in table "trade"?

     hi group,

    trying to create foreign key:

    ALTER TABLE porder1 ADD CONSTRAINT order_exist
    FOREIGN KEY (docuuserid) REFERENCES trade(tradeid) ON DELETE RESTRICT;

    column docuuserid is integer in porder1
    column tradeid    is serial  in trade and belong to primary key
    (single column)

    getting In EMS PostgreSQL
    ERROR:  insert or update on table "porder1" violates foreign key
    constraint "order_exist"
    DETAIL: Key (docuuserid)=(8415) is not present in table "trade".

    In PostgreSQL  Code Factory
    SQL Error: ERROR:  insert or update on table "porder1" violates
    foreign key constraint "order_exist"
    DETAIL:    Key (docuuserid)=(8415) is not present in table "trade".

    postgresql 8.4.4-1 on windows 7 ultimate 64 bit standard installation

    I'm not able to figure out what should be a problem.



    kindly regards
