A few questions:

1) Are you sure your RDBMS supports sub-queries?  Most do, but MySQL does

2) Have you tried echoing the query to see exactly what is being passed to
the RDBMS?  That is, perhaps session_id() or $customer_id is not giving a
valid value.

3) Using the results of (2) above, have you input the query into another
RDBMS client (i.e., command line version) to see what kind of errors are
