Thank you Joerg!
Its of great help. I'll try to explore things from here on BTEQ.. But let me know one thing. Whats the diff between full stat collection vs
sampling or random amp sampling? Is full means collecting the statics for all the columns for a table and the sampling and random amp sampling
means collecting stat for some perticular columns or columns combination or on index..? I am not getting any solid definition of these two types
of stat collection over the net.
Thanks & Regards
