【问题描述】:
这是我的Registration.aspx 文件的编码。每当我点击提交时,我都会得到 p>
System.Data.sqlclient.sqlexception:关键字“表”附近的语法不正确
这是代码部分。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Configuration;
public partial class Registration : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["RegistrationConnectionString"].ConnectionString);
conn.Open();
// This is the part im getting error in.
string checkuser = "select count(*) from Table where UserName ='" + uname.Text + "'";
SqlCommand com = new SqlCommand(checkuser, conn);
int temp = Convert.ToInt32(com.ExecuteScalar().ToString());
if (temp == 1)
{
Response.Write("User Already Exists");
}
conn.Close();
}
}
protected void Button1_Click(object sender, EventArgs e)
{
try
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["RegistrationConnectionString"].ConnectionString);
conn.Open();
string insertQuery = "insert into Table (UserName,Email,Password,Country) values (@uname ,@email ,@pass ,@country)";
SqlCommand com = new SqlCommand(insertQuery, conn);
com.Parameters.AddWithValue("@uname", uname.Text);
com.Parameters.AddWithValue("@email", email.Text);
com.Parameters.AddWithValue("@pass", pwd.Text);
com.Parameters.AddWithValue("@country", DropDownList1.SelectedItem.ToString());
com.ExecuteNonQuery();
Response.Redirect("Manager.aspx");
Response.Write("Registration Successful");
conn.Close();
}
catch (Exception ex)
{
Response.Write("Error:" + ex.ToString());
}
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
}
}

-
这个问题与jquery和visual studio无关。请注意适当地标记您的问题。

你确定你的表名是
Table? -
是的@KartikeyaKhosla
