Обсуждение: joining databases

how can i join separate DATABASES?

    select
        a.fld1,b.fld2
    from
        DBfirst.alphaTable  as a,
        DBsecond.bravoTable as b
    where
        a.xyz = b.pdq
    ;

if not possible, what's the procedure for breaking up tables
across various disk drives for speed optimization?

It can't be done

The simplest method is to use symbolic links.

Currently there is no way to acces more than one db at a time.. But i
heard that there will be implementation of schema pretty soon..
