Okay Thanks Jason,
Just let me clarify it.
In my comment table I will also add reply column and another primary key for that reply column. Right ?
So therefore their are two primary keys in the comment table. The first is the comment_id and the second is the reply_id. Right ?
Yes it is a reply comment, but what do you mean I will set the value of the reply column... blah blah blah ... ? Can you elaborate it well. I didn't understand what to do want to tell.
Thanks in Advanced Again ... :)
