Subj:   Re: Performance related issues in full statistics

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

-Rit
