Cross Database Table Joins In Drupal?

Is it possible to do cross database joins in drupal?

Say you have two databases, drupal and old_data_source. You want to join drupal.node to old_data_source.page.

db_set_active() can be called to use multiple databases. However can't find anything about cross database table joins!

MySQL Query - Table Set Up Issue

If I have a table set up like this:

Name | VARCHAR
Email | VARCHAR
Age | TINYINT | NULL (Default: NULL)

And I want the user to enter his or her name, email, and age - but AGE
is optional.

My insert would look something like:

INSERT INTO data (Name, Email, Age) VALUES ('$name', '$email', $age)

This is all good, except if the user doesn't enter an age. Then $age is
an empty variable. I thought that since the table is set up where Age
can be NULL, that this should be fine. But MySQL is giving me an error.
If $age is a number, it is no problem.

Query Time For Large MySQL Table

To preface my question I am a rookie in the PHP area, so forgive my incompetence.I am performing a query on a MySQL table and displaying the fields in a HTML table supported by DataTables, and due to the number of records I have stored in my table (5000+ rows) i have a big problem with the initial load time. I am using caching methods to enhance navigation beyond the initial load, however I still need a solution for reeling in the carp.I wanted to use the js datatables plugin to allow users quick access to paginated data, but if the load time hogs their memory and delays first glance...obviously I need to go a different route.
