Sergey,
I am looking at there site right now as we type, as there was an earlier thread about SQL, and I sort off booked marked it. I have to go through another party to get books from this Great and valued site, and some times it takes a few weeks to get here rather than days. This is why I posted on the net to see if I can get my fingers going on the keyboard to ge things going.
Regards
Iain Brodie
