无法查询外部表 - 批量加载数据转换错误

问：

嗨，我刚刚创建了我的外部表，它添加得很好，只是我似乎无法查询它。我一直收到此错误：

大容量加载数据转换错误（类型不匹配或字符无效） 对于指定的代码页），第 1 行的第 1 列 （Student_ID） dbo。ETStudents。

用于构建外部表的代码为：

CREATE EXTERNAL TABLE ETStudents
     (
     Student_ID INT,
     First_Name VARCHAR(25),
     Last_Name VARCHAR(25),
     Age INT,
     Over_18 TINYINT,
     Email VARCHAR(25),
     City VARCHAR(25),
     Country VARCHAR(25)
)WITH
 (
     DATA_SOURCE =course_data,
     LOCATION = '/MySQL_Project-Table_Students.csv',
     FILE_FORMAT = CsvFormat
 ); 

我是这样查询的：

SELECT TOP (100) 
[Student_ID]
,[First_Name]
,[Last_Name]
,[Age]
,[Over_18]
,[Email]
,[City]
,[Country]
 FROM [dbo].[ETStudents]

原始数据集为：

2,"Jordan","Parker",19,1,"[email protected]","London","England"
