Question

我收到以下错误消息：

字符串或二进制数据将被截断

我已经尝试过增加列大小但没有运气，我已经通过代码检查了一倍，但似乎无法找到任何问题。它在插入期间：

SqlCommand insert = new SqlCommand(@"INSERT 
into orderDetails 
(orderID, Name, Phone, Mobile, Email, DelName, DelRoad, DelTown, DelCity, DelCounty, DelPostCode, BilName, BilRoad, BilTown, BilCity, BilCounty, BilPostCode) 
values 
(@orderID , @Name , @Phone , @Mobile , @Email , @DelName , @DelRoad , @DelTown , @DelCity , @DelCounty , @DelPostCode , @BilName , @BilRoad , @BilTown , @BilCity , @BilCounty , @BilPostCode)", connection);
insert.Parameters.AddWithValue("@orderID", ID);
insert.Parameters.AddWithValue("@Name", name);
insert.Parameters.AddWithValue("@Phone", customer.Phone);
insert.Parameters.AddWithValue("@Mobile", customer.Mobile);
insert.Parameters.AddWithValue("@Email", customer.Email);
insert.Parameters.AddWithValue("@DelName", customer.DelName);
insert.Parameters.AddWithValue("@DelRoad", customer.DelRoad);
insert.Parameters.AddWithValue("@DelTown", customer.DelTown);
insert.Parameters.AddWithValue("@DelCity", customer.DelCity);
insert.Parameters.AddWithValue("@DelCounty", customer.DelCounty);
insert.Parameters.AddWithValue("@DelPostCode", customer.DelPostCode);
insert.Parameters.AddWithValue("@BilName", customer.BilName);
insert.Parameters.AddWithValue("@BilRoad", customer.BilRoad);
insert.Parameters.AddWithValue("@BilTown", customer.BilTown);
insert.Parameters.AddWithValue("@BilCity", customer.BilCity);
insert.Parameters.AddWithValue("@BilCounty", customer.BilCounty);
insert.Parameters.AddWithValue("@BilPostCode", customer.BilPostCode);
insert.ExecuteNonQuery();

这是我的表定义代码：

CREATE TABLE [dbo].[orderDetails] (
    [orderID]     INT         NOT NULL,
    [Name]        NCHAR (100) NULL,
    [Phone]       NCHAR (100) NULL,
    [Mobile]      NCHAR (15)  NULL,
    [Email]       NCHAR (15)  NULL,
    [DelName]     NCHAR (100) NULL,
    [DelRoad]     NCHAR (100) NULL,
    [DelTown]     NCHAR (100) NULL,
    [DelCity]     NCHAR (100) NULL,
    [DelCounty]   NCHAR (100) NULL,
    [DelPostCode] NCHAR (100) NULL,
    [BilName]     NCHAR (100) NULL,
    [BilRoad]     NCHAR (100) NULL,
    [BilTown]     NCHAR (100) NULL,
    [BilCity]     NCHAR (100) NULL,
    [BilCounty]   NCHAR (100) NULL,
    [BilPostCode] NCHAR (100) NULL,
    PRIMARY KEY CLUSTERED ([orderID] ASC)
);

客户类

public class Customer
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Phone { get; set; }
    public string Mobile { get; set; }
    public string Email { get; set; }
    public string DelName { get; set; }
    public string DelRoad { get; set; }
    public string DelTown { get; set; }
    public string DelCity { get; set; }
    public string DelCounty { get; set; }
    public string DelPostCode { get; set; }
    public string BilName { get; set; }
    public string BilRoad { get; set; }
    public string BilTown { get; set; }
    public string BilCity { get; set; }
    public string BilCounty { get; set; }
    public string BilPostCode { get; set; }
    public bool sameasDel { get; set; }
}

Answer 1

当您尝试插入一些对于该字段来说太大的数据时，会显示此消息。

此处的主要候选人是Email - 您只将其设置为15个字符，而大多数电子邮件地址将会更大！将其增加到255然后重试。

检查所有其他内容，尤其是Mobile等小内容。

Answer 2

每当你看到错误

    string or binary data would be truncated error message

请理解您正在尝试将值插入到无法保存您尝试插入的值的字段中

    [Mobile]      NCHAR (15)  NULL,
[Email]       NCHAR (15)  NULL,

他们只能容纳15个字符，请检查自己是否尝试插入更多字符。
