I'm interesting in deploy the .net authentication system but with a little changes. The first thing is changing the database that it uses by default to MySQL database.I'm not wondering in how/what to change on the web.config rather how to get the scripts that build all the database that it need(tables and so..).
After that I'll expend the user profile, maybe the roles and that enough for my website.So how to do a full move to MySql DB?
Why does a very simple script which inserts 26,000 records into a mysql database (myisam, no transactions) take 13 seconds in the php implementation, and then 35-50 seconds using mono+mysql connector? I thought asp.net was faster than php? Could the problem be the mono mysql connector is "platform independent", so the performance just stinks? or does asp.net suffer more overhead than php when it comes to executing each query? Aren't there any native linux binaries for mysql connector for mono that may be faster?
My code is to update a record if it already exists in database else insert as a new record. My code is as follows:
protected void Button3_Click(object sender, EventArgs e) { OdbcConnection MyConnection = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver};Server=localhost;Database=testcase;User=root;Password=root;Option=3;"); MyConnection.Open(); String MyString = "select fil_no,orderdate from temp_save where fil_no=? and orderdate=?"; OdbcCommand MyCmd = new OdbcCommand(MyString, MyConnection); MyCmd.Parameters.AddWithValue("", HiddenField4.Value); MyCmd.Parameters.AddWithValue("", TextBox3.Text); using (OdbcDataReader MyReader4 = MyCmd.ExecuteReader()) { //** if (MyReader4.Read()) { String MyString1 = "UPDATE temp_save SET order=? where fil_no=? AND orderdate=?"; OdbcCommand MyCmd1 = new OdbcCommand(MyString1, MyConnection); MyCmd1.Parameters.AddWithValue("", Editor1.Content.ToString()); MyCmd1.Parameters.AddWithValue("", HiddenField1.Value); MyCmd1.Parameters.AddWithValue("", TextBox3.Text); MyCmd1.ExecuteNonQuery(); } else { // set the SQL string String strSQL = "INSERT INTO temp_save (fil_no,order,orderdate) " + "VALUES (?,?,?)"; // Create the Command and set its properties OdbcCommand objCmd = new OdbcCommand(strSQL, MyConnection); objCmd.Parameters.AddWithValue("", HiddenField4.Value); objCmd.Parameters.AddWithValue("", Editor1.Content.ToString()); objCmd.Parameters.AddWithValue("", TextBox3.Text); // execute the command objCmd.ExecuteNonQuery(); } } }
I am getting the error as: ERROR [42000] [MySQL][ODBC 3.51 Driver][mysqld-5.1.51-community]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'order,orderdate) VALUES ('04050040272009',' &' at line 1
The datatype for fields in table temp_save are:
fil_no-->INT(15)( to store a 15 digit number) order-->LONGTEXT(to store contents from HTMLEditor(ajax control)) orderdate-->DATE(to store date)
protected void Button3_Click(object sender, EventArgs e) { //Create a connection to the database MySqlConnection conn = new MySqlConnection("Database=kid07025;Data Source=195.178.228.254;User Id=kid07025;Password=********"); //open the connection conn.Open(); //MySQL Query which updates the row where Anvandarnamn = Anvandarnamn (recieved from a cookie) MySqlCommand cmd = new MySqlCommand("UPDATE personer SET Information=?Information,Fnamn=?Fnamn,Enamn=?Enamn,Personnr=?Personnr,Adress=?Adress,Postnr=?Postnr,Ort=?Ort WHERE Anvandarnamn=?Anvandarnamn", conn); // Update with new text cmd.Parameters.AddWithValue("?Anvandarnamn", Request.Cookies["Anvandarnamn"].Value); cmd.Parameters.AddWithValue("?Information", TextBox1.Text); cmd.Parameters.AddWithValue("?Fnamn", TextBox2.Text); cmd.Parameters.AddWithValue("?Enamn", TextBox3.Text); cmd.Parameters.AddWithValue("?Personnr",TextBox4.Text); cmd.Parameters.AddWithValue("?Adress", TextBox5.Text); cmd.Parameters.AddWithValue("?Postnr", TextBox6.Text); cmd.Parameters.AddWithValue("?Ort", TextBox7.Text); cmd.ExecuteReader(); conn.Close(); RefreshProfile(); }
I don't know what I am doing wrong here, but the database doesn't get updated when I press the button.
I'm in the market for an ASP.NET host to start learning on and to host personal projects. I've noticed most of them provided both MySQL and MS SQL databases. However, usually they will only provided a couple MS SQL databases, but a large number (like 10) MySQL Databases. Can I use a MySQL database as a back end to a ASP.NET website? If so why would I want to pay extra to use MS SQL over MySQL?
I've installed the Components from the links below. But I still can't find any SQL references when I try to add them? I'm wondering if anyone would know the reason for this? I just started with asp.net. I've found several other questions regarding code for connecting but I can't find anyone who've had trouble with the Connector/components before?
I want to use MVC 2 with MySQL database. Is it possible?because my shared hosting limits the size of SQL Server database, but there is no limit on Size of MySQL database.MySQL seems to take less disk space than SQL Server database which is costly on the Internet.
When I build the website and upload everything as it is, I get this error:
Quote:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) I guess I have to deploy Database, or?

I found this code for user authentication. How secure is this? Can this be bypassed? Can I protect a MySQL database with a password? Can people see a MySQL database's data if it's not protected?
I did all the instructions which are in the following link: [URL] in order to do a connection between MySQL database and ASP.NET but I did not successed. Sometimes, it told me that I have a mistake in the <asp: button> and sometimes it told me that I did a mistake in calling (addImage) method. And this is my whole code:-
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="HW5._Default" %> <script> public class DataAccess { private string _strConn = @"Driver= {MySQLODBC 3.51 Driver};SERVER=localhost;DATABASE=test1;"; private OdbcConnection _objConn; public DataAccess() { this._objConn = new OdbcConnection(this._strConn); } // This function adds the Images to database public string addImage(timestamp id, byte [] data,string extension) { string strSql = "SELECT * FROM File"; DataSet ds = new DataSet("Image"); OdbcDataAdapter tempAP = new OdbcDataAdapter(strSql,this._objConn); OdbcCommandBuilder objCommand = new OdbcCommandBuilder(tempAP); tempAP.Fill(ds,"Table"); try { this._objConn.Open(); DataRow objNewRow = ds.Tables["Table"].NewRow(); objNewRow["Extension"] = extension; objNewRow["Data"] = buffer; objNewRow["ID"] = id; ds.Tables["Table"].Rows.Add(objNewRow); // trying to update the table to add the image tempAP.Update(ds,"Table"); }.....................................
I recently developed a Java Application for a client with MySQL database. Now he wants to have ASP.NET website connected with the Java Application. I'm thinking of placing the database on a local server which would support both the desktop application and the website. What i want to know is, is it the good way to handle these kind of scenario or is there any standard method?
I am developing a webapplication in ASP.NET 2.0 and MySQL 5.0 Now I want to upload this application to My WebServer (The windows web hosting space which I have purchased).
But I am not much familiar with MySQL, and I Don't Know how can I Upload the database on web server. This database contains approx 14 Tables and 95 Stored procedures. Recently I have developed some small web applications in asp.net with access database, at that time uploading was simple(just upload the access file to App_Data folder) But I don't know how i can do this with MySQL.
I watched many videos about using LINQ to SQL, I am happy I learned something,but is it the good way of using is: dragging and dropping and that's done???what are the best practices to use LINQ to access Database ( my database is not only SQL server..MYSQL..)
I have the following piece of code in my web.config file.. I am trying to connect to a MySQL database. The code compiles fine and when I am ruuning the website I come across this error - 'Keyword not supported: 'server'.':
I am using ASP.NET C# with mySql database. What is the best way for implementation of login system like Membership and Role. Membership and Role dont work with mySql database.
