What I remember is that select * from foo; where foo has millions of records, wil build the complete list as result set before it returns the first record. That may take long.

Isn't that true of every RDBMS?

And isn't it unavoidable (without the use of LIMIT) when using DBI? (Cos if there is a way around it, I'd love to see it.)

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
