Question

我需要帮助：我正在尝试使用网页作为界面向数据库插入多个值。当我尝试保存时，我收到了错误

＆＃34;关键字＆＃39;值＆＃39;附近的语法不正确。＆＃34;

以下C＃代码供您参考。

using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Data.SqlClient;

public partial class _Default : System.Web.UI.Page
{
    SqlConnection con = new SqlConnection("Data Source=INHRPSM1D7C;Initial Catalog=Controller_Forecast;Integrated Security=True;");

    protected void Page_Load(object sender, EventArgs e)
    {
    }

    public void refress()
    {
        TextBox1.Text = "";
        TextBox2.Text = "";
        TextBox3.Text = "";
        TextBox4.Text = "";
        TextBox5.Text = "";
        TextBox6.Text = "";
        TextBox7.Text = "";
        TextBox8.Text = "";
        TextBox9.Text = "";
        TextBox10.Text = "";
        TextBox11.Text = "";
        TextBox12.Text = "";
        DropDownList1.Text = "";
        DropDownList2.Text = "";
    }

    protected void btnSave_Click(object sender, EventArgs e)
    {
        SqlCommand cmd = new SqlCommand("insert into Controller_Forecast(C1,C2,C3,C4,C5,C6,C7,C8,C9,C10,C11,C12,C13) values('" +
            TextBox1.Text + "','" + TextBox2.Text + "','" + TextBox3.Text +

            DropDownList5.Text + "','" + DropDownList6.Text + "')",con);

        cmd.CommandType = CommandType.Text;
        try
        {
            con.Open();
            cmd.ExecuteNonQuery();
            Literal1.Text = "Data Updated Successfully!!!";
            con.Close();
            refress();
        }
        catch (Exception ex)
        {
            Literal1.Text = ex.Message;
        }
    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        refress();
        Literal1.Text = "";
    }
}

Answer 1

您不能像尝试使用INSERT statement那样执行2组值。你有效地做了：

INSERT INTO Controller_Forecast(C1,C2...)
VALUES(...loads of values...)
VALUES(...Loads of more values...)

这是无效的。要插入2组数据，这就是你想要做的事情，你可以做2 INSERT INTO语句或用逗号分割值列表，如下所示：

多个插入语句

INSERT INTO Controller_Forecast(C1,C2...)
VALUES(...your first set of values...)
INSERT INTO Controller_Forecast(C1,C2...)
VALUES(...your second set of values...)

以逗号分隔

INSERT INTO Controller_Forecast(C1,C2...)
VALUES(...your first set of values...), (...second set of values...)

然而，这似乎效率低下，你最好在商店程序中编写它并参数化你的值以避免sql注入。

Answer 2

你有两次“价值”。你能试试吗？

“插入 Controller_Forecast（C1，C2，C3，C4，C5，C6，C7，C8，C9，C10，C11，C12，C13）值（'“+ TextBox1.Text +“'，'”+ TextBox2.Text +“'，'”+ TextBox3.Text + “'，'”+ TextBox4.Text +“'，'”+ TextBox5.Text +“'，'”+ TextBox6.Text + “'，'”+ TextBox7.Text +“'，'”+ TextBox8.Text +“'，'”+ TextBox9.Text + “'，'”+ TextBox10.Text +“'，'”+ TextBox11.Text +“'，'”+ TextBox12.Text + “'，'”+ DropDownList1.Text +“'，'”+ DropDownList2.Text +“'，'”+ DropDownList3.Text +“'）”，con）;

无法将多个值插入数据库
