This article describes how to add MySQL support to Microsoft Visual Studio. With MySQL and Visual Studio integration, you can develop Microsoft .NET applications that access MySQL databases on A2 Hosting servers.
Visual Studio does not include support for MySQL by default. To add MySQL support to Visual Studio, you must install the following components:
You should download and install both of these components to obtain the best possible MySQL integration with Visual Studio.
After you install the MySQL for Visual Studio component, you can use Visual Studio's visual database tools to access and view MySQL databases on A2 Hosting servers.
The following procedure demonstrates how to use the Server Explorer to view MySQL databases on your A2 Hosting account.
You can double-click any of these items to navigate through the database. For example, to see the tables defined in the database, double-click Tables. To view the actual data stored in a table, right-click the table name, and then click Retrieve Data.
After you install the Connector/Net component, you can write .NET code that accesses MySQL databases. To do this, you must add a reference to the MySQL .NET library in your project, and specify the correct parameters in a database connection string.
The following procedure demonstrates how to create a simple C# or Visual Basic console application that connects to a remote MySQL database and runs an SQL query.
Copy the following code for the language you selected in step 3, and then paste it into the code window. Modify the connstring definition to use the login information for your own database. Additionally, replace the three instances of table_name with the name of the table you want to query.
Visual C#:
using System;
using System.Data;
using MySql.Data.MySqlClient;
namespace MySQL_test
{
class Program
{
static void Main(string[] args)
{
string connstring = @"server=example.com;userid=example_user;password=example_password;database=example_database";
MySqlConnection conn = null;
try
{
conn = new MySqlConnection(connstring);
conn.Open();
string query = "SELECT * FROM table_name;";
MySqlDataAdapter da = new MySqlDataAdapter(query, conn);
DataSet ds = new DataSet();
da.Fill(ds, "table_name");
DataTable dt = ds.Tables["table_name"];
foreach (DataRow row in dt.Rows)
{
foreach (DataColumn col in dt.Columns)
{
Console.Write(row[col] + "\t");
}
Console.Write("\n");
}
}
catch (Exception e)
{
Console.WriteLine("Error: {0}", e.ToString());
}
finally
{
if (conn != null)
{
conn.Close();
}
}
}
}
}
Visual Basic:
Imports System
Imports System.Data
Imports MySql.Data.MySqlClient
Module Module1
Sub Main()
Dim connstring As String = "server=example.com;userid=example_user;password=example_password;database=example_database"
Dim conn As MySqlConnection = Nothing
Try
conn = New MySqlConnection(connstring)
conn.Open()
Dim query As String = "SELECT * FROM table_name;"
Dim da As New MySqlDataAdapter(query, conn)
Dim ds As New DataSet()
da.Fill(ds, "table_name")
Dim dt As DataTable = ds.Tables("table_name")
For Each row As DataRow In dt.Rows
For Each col As DataColumn In dt.Columns
Console.Write(row(col).ToString() + vbTab)
Next
Console.Write(vbNewLine)
Next
Catch e As Exception
Console.WriteLine("Error: {0}", e.ToString())
Finally
If conn IsNot Nothing Then
conn.Close()
End If
End Try
End Sub
End Module
Scroll down the list of assemblies, and then double-click MySql.Data. A check box appears next to the assembly name.
