Hi all,
I do it in table synop:
ALTER TABLE synop
ADD CONSTRAINT estacoes_fk
FOREIGN KEY (id_estacao)
REFERENCES estacoes
Then I check the DDL and it is like this:
....
CONSTRAINT estacoes_fk FOREIGN KEY (id_estacao, id_estacao) REFERENCES
estacoes (id_estacao, id_estacao)
....
- Why id_estacao is duplicated????
- id_estacao is the only column in pk of estacoes.
Tks
