Dear Thaigu its time to go and attend some Computer institute, and learn like other had done. I had seen your and few others questions in the past two weeks and come to the following views. (Before throwing your so basic questions please refer to a manual or do some effort. ) Dear frends on the forums, its good to guide and lend a helping hand to a fellow but to help by giving free ride to an unqualified / untrained person, is to harm other qualified person who can do a better job where ever Thaigoo is working, there will be many qualified DBAs in that part of the world looking for a job or can be hired by the company where Thaigoo works and help Thaigoo for some money. I know many will hate me for this reply specailly Thaigoo but many qualified proffesional will under stand from where I am comming from or going to. Nisar Tareen (Help a fellow DBA).
