錯誤代碼 1452 mysql 出現在 windows 但不在 linux

Question

我有一個 django 項目，它在 manage.py 遷移后創建表。 我對兩者都使用了一些 LOAD DATA LOCAL INFILE MySQL 查詢。 我有 7 張桌子。 所有前 6 個表在 Linux 和 Windows 中的填充方式相同。 除了最后一個表在以前的表中有一些外鍵。

Windows 和 Linux 表都在 InnoDB 中，並且父表具有完全相同的數據。

INSERT INTO `seas_database`.`section_t`
(`eSession`,`eDays`,`dYear`,`nSectionNumber`,`nSectionCapacity`,`nEnrolled`,`bIsBlocked`,`tStartTime`,`tEndTime`,`cCoffCode_ID`,`cFaculty_ID`,`cRoom_ID`)
VALUES
("Spring","F",2009,1,250,43,0,"14:00","15:30","AAT101","T001","C10210-S");

證明 AAT101 存在於 Windows

然而我只在 Windows 中得到這個錯誤。 不在 Linux 中。

Error Code: 1452. 
Cannot add or update a child row: 
a foreign key constraint fails 
(`seas_database`.`section_t`, CONSTRAINT `section_t_cCoffCode_ID_ade53504_fk_cooffered` FOREIGN KEY (`cCoffCode_ID`) 
REFERENCES `coofferedcourse_t` (`cCoffCode_ID`))

Linux MySQL版本：

mysql  Ver 8.0.27 for Linux on x86_64 (MySQL Community Server - GPL)

Windows MySQL 版本：

C:\Program Files\MySQL\MySQL Server 8.0\bin\mysql.exe  Ver 8.0.27 for Win64 on x86_64 (MySQL Community Server - GPL)

如果有幫助，運行 LOAD DATA INFILE 的 csv 由 Pandas 從 xlsx 文件修改和創建。

編輯 1：顯示 django sqlmigrate

WINDOWS：

Answer 1

事實證明，該解決方案確實是特定於平台的。 自動生成的 csv 文件中的行終止字符我正在從中加載數據，在 Windows 和 Linux 中有所不同。 因此，在 linux 中，我從未遇到過以下代碼的問題，

-- Populating CoOfferedCourse_T
LOAD DATA LOCAL
INFILE "path/to/foo.csv" 
INTO TABLE coofferedcourse_t 
FIELDS TERMINATED BY "\t"
IGNORE 1 LINES 
(@COFFER_COURSE_ID,@COFFERED_WITH)
SET cCoffCode_ID=@COFFERED_WITH,cCourse_ID=@COFFER_COURSE_ID;

在 windows 中，我必須添加

LINES TERMINATED BY '\r\n'

之后，兩個平台中的表格狀態變得相同
