mysql 1452 在使用插入表时

Question

我在尝试将数据插入我的数据库时遇到 1452 错误。 这是我所做的:

create table Agenzia(
PartitaIva char(11) primary key,
Nome varchar(20) not null unique,
Pass varchar(20) not null,
Indirizzo varchar(35),
NumeroTelefonico varchar(10)
);

create table Parco(
Nome varchar(20) primary key,
Indirizzo varchar(35),
NumeroTelefonico varchar(11),
Cap decimal(5)
);

create table Affiliazione(
Agenzia char(11) not null,
Parco varchar(20) not null,
foreign key (Agenzia) references Agenzia(PartitaIva) on delete cascade on update cascade,
foreign key (Parco) references Parco(Nome) on delete cascade on update cascade,
primary key(Agenzia,Parco)
);

LOAD DATA LOCAL INFILE 'mypath\\Agenzia.csv'
    INTO TABLE Agenzia
        FIELDS TERMINATED BY ';' LINES TERMINATED BY '\n'
    ();

LOAD DATA LOCAL INFILE 'mypath\\Parco.csv'
    INTO TABLE Parco
        FIELDS TERMINATED BY ';' LINES TERMINATED BY '\n'

直到这一点，我没有收到任何错误并且数据到达了它们的位置，当我检查选择时，我尝试执行:

LOAD DATA LOCAL INFILE 'mypath\\Affiliazione.csv'
    INTO TABLE Affiliazione
        FIELDS TERMINATED BY ';' LINES TERMINATED BY '\n'
    ();

我得到了这个错误:

0 row(s) affected, 10 warning(s): 1452 Cannot add or update a child row: a foreign key constraint fails (parchidb.affiliazione, CONSTRAINT affiliazione_ibfk_2 FOREIGN KEY (Parco) REFERENCES Parco (Nome) ON DELETE CASCADE ON UPDATE CASCADE)

重复10次

这是我试图用来自动填充我的数据库的 csv:

奇怪的是，如果尝试手动插入“Affilizione”的值，我没有引用错误，是不是我做错了什么？

Answer 1

好的。那就是'\r\n'而不是'\n'。用notepad++发现的。要使其正常工作，只需将 LINES TERMINATED BY '\n' 替换为 LINES TERMINATED BY '\r\n'
