Subj:   Estimating row count

All,

I need to know what is the least cost-effective method of getting the row count(assuming we have tables with more than a billion rows - and the size of the database is huge - Terabytes)

Obvious answer to getting the row count is:

select count(*) from ;

But a count(*) w.r.t a huge table under consideration is too costly a deal.

So what are the alternatives?
