Refresh Database Manually

Well i think there is no need to refresh the database you can do it in following manner:

Step 1-
// Code for storing the message details into your databasetable

Step 2-
// Code for sending that message and take the response whether it sent or not

Step 3-
//if(message_sendSuccessfull)
{
  // code for storing it into SentSuccessTable
}
else
{
// code for inform user that your message has not been sent
}

Hi Ipsita,
please clarify one thing that when do you want to send message from your database?
