mysql - 尽管数据看似合适，但插入时为 "String or binary data would be truncated"

Question

我有一个这样的表:

CREATE TABLE Customers
(CustomerID int Identity (1,1) NOT NULL PRIMARY KEY,
customerName varchar (50),
Address varchar (255),
Phone int NOT NULL,
Email varchar,
Gender varchar,
Age int, 
);

我尝试像这样插入到这个表中:

Insert into Customers (customerName, Address, Phones, Email, Gender, Age)
Values ('Anosa Seunge', 'Keskuskatu 200', 358-3-4180, 'ijiosd@ao.com', 'Male', 19),
        ('Jihad Christian', '305 - 14th Ave. Suite 3B', 358-1-3688, 'jihado@ao.com', 'Female', 29);

并收到此错误:

Msg 8152, Level 16, State 14, Line 4
String or binary data would be truncated.
The statement has been terminated.

Answer 1

您的电子邮件和性别字段的长度为1，这可能是您想要的性别(尽管可能不基于您的insert 语句)，但肯定不适用于电子邮件。

你想要这样的东西:

CREATE TABLE Customers
(CustomerID int Identity (1,1) NOT NULL PRIMARY KEY,
customerName varchar (50),
Address varchar (255),
Phone int NOT NULL,
Email varchar(50),
Gender varchar(50),
Age int, 
);
