This document explains how to dynamically create a connection to a SQL Anywhere Studio database through a C# project.
Required Software
Sybase SQL Anywhere Studio 7.x or later
asademo.db file (included with Adaptive Server Anywhere)
ASA 8.0 Sample data source (created by default when Adaptive Server Anywhere is installed)
Microsoft Visual Studio .NET version 7.0
Microsoft ADO.NET
Windows NT, 98, 2000, Me, or XP
Steps
Start Visual Studio .NET.
Create a new project.
Select Visual C# Projects from the left side.
Select Console Application from the right side.
Enter the project name CustomerDataReader.
Enter the project location: c:\temp.
Click OK to close the New Project dialog.
In your code, you must set the System.Data name space. This is where all the ADO.NET classes are located. Enter the following using directive at the beginning of your project:
Using system.Data;
The next required using directive is the OLE DB .NET Data Provider. Add the following using directive to your project to use the Microsoft OLE DB .NET provider:
Using System.Data.OleDb;
Your source should now look like the following:
using System;
using System.Data;
using System.Data.OleDb;
namespace CustomerDataReader
{
/// <summary>
/// Summary description for Class1.
/// </summary>
class Class1
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
//
// TODO: Add code to start application here
//
}
}
}
Now you can write the code required to establish communication between Adaptive Server Anywhere and your C# application.
Add the following code to the public static void Main() function after the //TODO: Add code to start application here comment:
//Set your connection string
OleDbConnection myConnection = new OleDbConnection(
@"Data Source=ASA 8.0 Sample;Provider=ASAProv.80");
//open the connection
myConnection.Open();
//Creating command object.
OleDbCommand myCommand = myConnection.CreateCommand();
//Specify query
myCommand.CommandText = "Select fname, lname from Customer";
//DataReader for the command
OleDbDataReader myDataReader = myCommand.ExecuteReader();
//Let's display data
while ( myDataReader.Read())
{
Console.WriteLine("\t{0}\t{1}",
myDataReader["fname"],myDataReader["lname"]);
}
myDataReader.Close();
myConnection.Close();
Run the project by pressing CTRL+F5.
