Hi,

i need to get data from sql server to my application in android mobile for that one

1. Installed sql server 2008 and created one database

2. Created sample project with jtds and sqljdbc4 jar files.

my code

public class ConnectionTask extends AsyncTask<void,>
	{
		 Connection conn = null;
		  String connString = "jdbc:jtds:sqlserver://localhost:1433/Sample";
		@Override
		protected String doInBackground(Void... params) {
			
			 try {
	             String driver = "net.sourceforge.jtds.jdbc.Driver";
	             Class.forName(driver);
	          
	           
	            String username = "";
	            String password = "";
	            conn = DriverManager.getConnection(connString,username,password);
	            Log.d("Connection","open");       
	            Statement stmt = conn.createStatement();    
	            ResultSet reset = stmt.executeQuery("select * from sree");

	           //Print the data to the console    
	          while(reset.next()){
	            Log.d("Data:",reset.getString(1));
	          
	          }
	         conn.close();

	      } catch (Exception e)       
	         { 
	             Log.d("Error connection","" +
	           e.getMessage());
	          }
			return null;
		}
}
