【英文标题】：Error Code: 1366. Incorrect integer value: 'NULL' for column 'ReportsTo' at row 2

【问题描述】：

在我从 .csv 文件加载数据时创建表后，它显示错误：

“错误代码：1366。不正确的整数值：列的'NULL' 'ReportsTo' 在第 2 行"。

我的 csv 文件在第 2 行有空值。我已经搜索了互联网，但我没有找到解决方案。我正在使用北风数据。

【问题讨论】：

你能告诉我们那一排吗？

我一直发现将 CSV 数据批量加载到所有字段都是可为空的 VARCHAR 的表中作为暂存，然后将其作为步骤 2 插入到真实表中更容易，而不是尝试在批量加载过程中与垃圾搏斗..

您应该阅读“NULL 值的处理因所使用的 FIELDS 和 LINES 选项而异”部分：-dev.mysql.com/doc/refman/8.0/en/load-data.html 并发布您遇到问题的行示例。

在该行写入 NULL。 @jarlh

您尝试过什么调试问题？这甚至与编程有关吗？

【参考方案1】：

显然，您需要特殊处理来处理该值。您没有指定哪个值，但一种方法是使用变量。那么，如果salary哪里出了问题：

LOAD DATA INFILE 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/employees.csv'
INTO TABLE EmployeeS (EmployeeId, LastName, . . . , @salary)
    SET salary = (CASE WHEN @salary <> 'NULL' THEN CAST(@salary AS FLOAT) END)
FIELDS TERMINATED BY ','
IGNORE 1 ROWS;

当然，我不知道哪一栏是真正的问题。这只是说明如何修复它。

也就是说，您可能还有其他问题。我希望数据与表中的列对齐，您可能想了解它们为什么不对齐。

【讨论】：

您的意思是“如果 salary 是问题所在”？

在 .csv 文件中，ReportsTo 列中有 NULL。试过这段代码不起作用。 @戈登林诺夫

我认为salary 不是问题所在。 @朱莉娅

@GHOSTRIDER，薪水总是是个问题，无论是对员工还是对公司...

【参考方案2】：

此代码有效。

LOAD DATA INFILE 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/employees.csv'
INTO TABLE Employees
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
IGNORE 1 ROWS;
