You will find herebelow the sql schema, to import into a mysql 5.0 database. I used mysql --default-character-set=utf8 to import it.

The error does not happen if the last line of the schema (adding a foreign key) is removed.

Thanks for any help.

----
DROP TABLE IF EXISTS Catégorie;
CREATE TABLE Catégorie
(
ID Int8
);

DROP TABLE IF EXISTS Transaction;
CREATE TABLE Transaction
(
Compte_positif Int8
);
alter table Catégorie ADD INDEX(ID);
alter table Transaction add constraint youpee foreign key (Compte_positif) references Catégorie(ID);
