  *: Multiple databases are not supported.  For example, the following construct for creating a table in a database db1 based on a table in database db2 won't work: create table db1.table1 as select * from db2.table1; But I often need this.  So, it should looks like a schemas in ORACLE database.
- Comment from a second user: The documentation under {link http://sqlite.org/lang.html#expr Expressions} allows for database names.  I'd be happy enough if that could work somehow (even so, I don't see how the current PHP 5RC would allow for it).  [My particular context being that one database of Users, say, belongs in one place (file) logically, while each type of service might have its own separate database, no problem.  But complicated queries against this type of 'separate databases system' run into severe issue under the current scheme.]
