10 by default if I recall properly.

Can be perhaps be increased to 62 at most:

The table names stay the same. Each attached database can have a unique name.

So, for example:

attach … as attached01;
attach … as attached02;
...

with
DataSet
as
(
  select count( * ) as count
  from   attached01.table

  union all
  select count( * ) as count
  from   attached01.table

  union all
  ...
)
select sum( count ) as sum
from     DataSet;
