Asp net with mysql database tutorial
This tutorial will teach you how to connect to MySQL from .NET Core using C#. Show
1. Install MySqlConnectorFirst, install the MySqlConnector NuGet package. From a command prompt, run:
Or right-click your project, choose Manage NuGet Packages…, in the Search box enter 2. Connection StringA typical connection string for MySQL is:
Replace the values in that string with the appropriate settings for your database. For more advanced settings, see Connection Options. If you are using ASP.NET Core, your connection string will usually be stored in
3. Configure Service (ASP.NET Core)If using ASP.NET Core, you will want to register a database connection in
4. Open and Use the ConnectionIn ASP.NET Core, the
You can then open the connection and execute a query:
Abstract.NET is the new distributed computing platform developed by Microsoft and ASP.NET is its programming model for web development. I'm creating a Web Form with a Overview of the SolutionMySQL:MySQL Server 4.0 laid the foundation for the new features implemented in MySQL 4.1, such as subqueries and Unicode support, which were desired by many of our customers. The server is available as a separate program for use in a client/server networked environment. It is also available as a library that can be embedded (linked) into standalone applications. Such applications can be used in isolation or in environments where no network is available. Clients can connect to a MySQL server using TCP/IP sockets on any platform. On Windows systems belonging the NT family (NT, 2000, XP, or 2003), clients can connect using named pipes. On UNIX systems, clients can connect using UNIX domain socket files. In MySQL 4.1, we cannot write stored procedures, functions, or views. The following are sample SELECT column_names from table_name [WHERE ...conditions]; UPDATE table_name SET column_names = ‘’ WHERE ...conditions; DELETE FROM table_name WHERE ...conditions; ODBC:The Microsoft Open Database Connectivity (ODBC) interface is a C programming language interface that makes it possible for applications to access data from a variety of database management systems. The ODBC interface permits maximum interoperability — an application can access data in diverse DBMSs through a single interface. Furthermore, that application will be independent of any DBMS from which it accesses data. Users of the application can add software components called drivers, which interface between an application and a specific DBMS. Applications that use ODBC are responsible for any cross-database functionality. For example, ODBC is not a heterogeneous join engine, nor is it a distributed transaction processor. However, because it is DBMS-independent, it can be used to build such cross-database tools. The following will explain to you the architecture of ODBC: Namespace used for ODBC: using System.Data.Odbc; The The .NET Framework Data Provider for ODBC describes a collection of classes
used to access an ODBC data source in the managed space. Using the Solution with CodeFirst, let us see how to connect ASP.NET with a MySQL database. The following code will explain how to connect with a MySQL 4.1 database: private const string ConnStr = "Driver={MySQL ODBC 3.51 Driver};Server=localhost;" + "Database=test;uid=root;pwd=;option=3"; private void BindDataGrid() { using(OdbcConnection con = new OdbcConnection(ConnStr)) using(OdbcCommand cmd = new OdbcCommand("SELECT * FROM Sample", con)) { con.Open(); DataGrid1.DataSource = cmd.ExecuteReader( CommandBehavior.CloseConnection | CommandBehavior.SingleResult); DataGrid1.DataBind(); } } This snippet shows the code to bind data from a MySQL database to a private void InsertInfo() { if(CheckIsAddNameValid()) { HtmlTable2.Visible = false; using(OdbcConnection con = new OdbcConnection(ConnStr)) using(OdbcCommand cmd = new OdbcCommand("INSERT INTO sample" + "(name, address) VALUES (?,?)", con)) { cmd.Parameters.Add("@name", OdbcType.VarChar, 255).Value = TextBox3.Text.Trim(); cmd. Parameters.Add("@address", OdbcType.VarChar, 255).Value = TextBox4.Text.Trim(); con.Open(); cmd.ExecuteNonQuery(); BindDataGrid(); } } } private void UpdateInfo(int id, string name, string address) { using(OdbcConnection con = new OdbcConnection(ConnStr)) using(OdbcCommand cmd = new OdbcCommand("UPDATE sample " + "SET name = ?, address = ? WHERE ID = ?", con)) { cmd.Parameters.Add("@name", OdbcType.VarChar, 255).Value = name; cmd.Parameters.Add("@address", OdbcType.VarChar, 255).Value = address; cmd.Parameters.Add("@ID", OdbcType.Int).Value = id; con.Open(); cmd.ExecuteNonQuery(); } } private void DeleteInfo(int id) { using(OdbcConnection con = new OdbcConnection(ConnStr)) using(OdbcCommand cmd = new OdbcCommand("DELETE " + "FROM sample WHERE ID = ?", con)) { cmd.Parameters.Add("@ID", OdbcType.Int).Value = id; con.Open(); cmd.ExecuteNonQuery(); } } The table design for this sample:CREATE TABLE sample ( id int AUTO_INCREMENT NOT NULL, name varchar(45) NOT NULL, address varchar(45) NOT NULL, PRIMARY KEY(id) ) GO Details about the DataGrid:The private void DataGrid1_UpdateCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e) { try { int cUsrID ; string strName; string strAddress; Literal ltID; TextBox txtTempName; TextBox txtTempAddress; ltID = (System.Web.UI.WebControls.Literal ) e.Item.Cells[0].FindControl("Label"); cUsrID = Convert.ToInt32 (ltID.Text); txtTempName = (System.Web.UI.WebControls.TextBox) e.Item.Cells[1].FindControl("TextBox1"); strName = txtTempName.Text; txtTempAddress = (System.Web.UI.WebControls.TextBox) e.Item.Cells[2].FindControl("Textbox2"); strAddress = txtTempAddress.Text; UpdateInfo(cUsrID, strName, strAddress); DataGrid1.EditItemIndex = -1; BindDataGrid(); } catch(Exception ex) { } } ConclusionAfter reading this article, you will have a basic knowledge about ODBC connections, Reference

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages. Can you use ASP net with MySQL?NET Core and MySQL are both free and open source technologies. The new ASP.NET Core can run on Linux and in Linux Containers, and MySQL is one of the easiest databases to get started with. This makes the combination of ASP.NET Core and MySQL a pretty compelling combination.
Which database is best for ASP NET?SQL Server is the most popular database when talking about ASP.NET Core since it's what Microsoft is also selling and also the first one that Entity Framework Core is developed for. It's not free mind you. You can now use SQL Server in Linux as Microsoft has developed a Linux version that you can use.
Can C# work with MySQL?Connect C# to MySQL
All the communication between a C# application and the MySQL server is routed through a MySqlConnection Object. So, before your application can communicate with the server, it must instantiate, configure, and open a MySqlConnection object.
Can I use MySQL with Visual Studio?Many MySQL for Visual Studio features also require that MySQL Connector/NET be installed on the same host where you perform Visual Studio development. Connector/NET is a separate product. The options for installing MySQL for Visual Studio are: Using MySQL Installer (preferred): Download and execute the MySQL Installer.
