文件后面的代码
受保护的void Submit_Click(对象发送者，EventArgs e)
{
SqlConnection con =新的SqlConnection();
con.ConnectionString = ConfigurationManager.ConnectionStrings ["sampleConnectionString2"].ToString();
con.Open();
SqlCommand cmd =新的SqlCommand("UPDATE Users SET Password =""+ NPwd.Text.Trim()+"其中UserName =""+ UserId.Text +""AND Password =""+ Pwd.Text + ");
cmd.ExecuteNonQuery();
con.Close();
Response.Write(< script language = Javascript> alert(``您的密码已更改，请使用新密码登录'')</script>");
Response.Redirect(〜/Default.aspx");
}
}
在执行nonquery
code behind file
protected void Submit_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection();
con.ConnectionString = ConfigurationManager.ConnectionStrings["sampleConnectionString2"].ToString();
con.Open();
SqlCommand cmd=new SqlCommand("UPDATE Users SET Password=''" +NPwd.Text.Trim()+ "'' where UserName = ''" +UserId.Text+ "'' AND Password=''" +Pwd.Text+ "''");
cmd.ExecuteNonQuery();
con.Close();
Response.Write("<script language=Javascript>alert(''Your Password Has Been Changed,Please Login With New Password'')</script>");
Response.Redirect("~/Default.aspx");
}
}
its showing error while updating password in execute nonquery
推荐答案
SqlCommand cmd=new SqlCommand("UPDATE Users SET Password='" +NPwd.Text.Trim()+ "' where UserName = '" +UserId.Text+ "' AND Password='" +Pwd.Text+ "'",con);
