MySQL Query - Table Set Up Issue

If I have a table set up like this:

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.
