在SQL Server中插入新记录

我在这里甚至在Visual Studio中都还是新手，所以我不完全知道Visual Studio中的所有功能。我试图将数据插入到SQL Server中。当我运行这些代码并输入必要的信息时，我的标签消息就会显示出来，但是当我查看SQL Server时，没有任何变化。 Visual Studio已连接到SQL Server。我在这里先向您的帮助表示感谢。在SQL Server中插入新记录

是SQL服务器上的命令？你的列类型到底是什么？如何尝试使用'Add'方法添加参数并指定它的类型和大小？ ['AddWihValue' _might_有时会产生意外的结果]（http://blogs.msmvps.com/jcoehoorn/blog/2014/05/12/can-we-stop-using-addwithvalue-already/）并使用'using'语句自动处理连接和命令，而不是手动调用'Close'方法。 –

您是否尝试过通过ssms或sqlcmd运行查询？它是否工作，然后，什么都不做或给出错误信息？ – BeanFrog

'1.使用事务和异常处理''2。使用Sql Profiler来跟踪发送给SQL Server的值。 –

试试这个

using(SqlConnection vid = new SqlConnection("Data Source=JOSAN;Initial Catalog=AdventureWorks2012;Integrated Security=True")) 
{ 
    using(SqlCommand xp = new SqlCommand()) 
    { 
     xp.CommandText = @"Insert into HumanResources.Employee(NationalIDNumber, LoginID, JobTitle, BirthDate, MaritalStatus, Gender, HireDate, SalariedFlag, VacationHours, SickLeaveHours, CurrentFlag, ModifiedDate) Values(@NationalIDNumber, @loginID, @JobTitle, @BirthDate, @MaritalStatus, @Gender, @HireDate, @SalariedFlag, @VacationHours, @SickLeaveHours, @CurrentFlag, @ModifiedDate)"; 
     xp.Connection = vid; 
    xp.Parameters.AddWithValue("@NationalIDNumber", TextBox1.Text); 
    xp.Parameters.AddWithValue("@LoginID", TextBox2.Text); 
    xp.Parameters.AddWithValue("@JobTitle", TextBox3.Text); 
    xp.Parameters.AddWithValue("@BirthDate", TextBox4.Text); 
    xp.Parameters.AddWithValue("@MaritalStatus", Convert.ToChar(TextBox5.Text); 
    xp.Parameters.AddWithValue("@Gender", TextBox6.Text); 
    xp.Parameters.AddWithValue("@HireDate", TextBox7.Text); 
    xp.Parameters.AddWithValue("@SalariedFlag", TextBox8.Text); 
    xp.Parameters.AddWithValue("@VacationHours", TextBox9.Text); 
    xp.Parameters.AddWithValue("@SickLeaveHours", TextBox10.Text); 
    xp.Parameters.AddWithValue("@CurrentFlag", TextBox11.Text); 
    xp.Parameters.AddWithValue("@ModifiedDate", TextBox12.Text); 
     try 
     { 
      vid.Open(); 
      xp.ExecuteNonQuery(); 
     } 
     catch 
     { 
      MessgeBox.Show(e.Message.ToString(), "Error Message"); 
      vid.Close(); 
     } 
     if (IsPostBack) 
     { 
      TextBox1.Text = ""; 
      TextBox2.Text = ""; 
      TextBox3.Text = ""; 
      TextBox4.Text = ""; 
      TextBox5.Text = ""; 
      TextBox6.Text = ""; 
      TextBox7.Text = ""; 
      TextBox8.Text = ""; 
      TextBox9.Text = ""; 
      TextBox10.Text = ""; 
      TextBox11.Text = ""; 
      TextBox12.Text = ""; 
     } 
    } 
}

编辑

您可以使用隐式转换AddWithValue并更改声明这样

xp.Parameters.AddWithValue("@NationalIDNumber", TextBox1.Text); 
xp.Parameters.AddWithValue("@LoginID", TextBox2.Text); 
xp.Parameters.AddWithValue("@JobTitle", TextBox3.Text); 
xp.Parameters.AddWithValue("@BirthDate", TextBox4.Text); 
xp.Parameters.AddWithValue("@MaritalStatus", Convert.ToChar(TextBox5.Text); 
xp.Parameters.AddWithValue("@Gender", TextBox6.Text); 
xp.Parameters.AddWithValue("@HireDate", TextBox7.Text); 
xp.Parameters.AddWithValue("@SalariedFlag", TextBox8.Text); 
xp.Parameters.AddWithValue("@VacationHours", TextBox9.Text); 
xp.Parameters.AddWithValue("@SickLeaveHours", TextBox10.Text); 
xp.Parameters.AddWithValue("@CurrentFlag", TextBox11.Text); 
xp.Parameters.AddWithValue("@ModifiedDate", TextBox12.Text);

为什么你认为在命令上使用逐字串会改变什么？它不会包含任何转义字符。 –

@SonerGönül：谢谢你的通知。让我改变它 –
