MS-SQL query question

SELECT     patient_name.*, patient_address.*, doctor.*
FROM         patient_name CROSS JOIN
                      patient_address CROSS JOIN
                      doctor
where <myDatecolumn> > dateadd("m",-12,getdate())

I tried to grab billing dates from a billing submission table called reconsideration_table and it bombs

Msg 170, Level 15, State 1, Line 6
Line 6: Incorrect syntax near '<'.

The server will gag from those CROSS JOINs, because they are inappropriate here.

Something like below will be close, although it's probably still not quite right, since there should be a "doctor_patient" table and/or a "patient_visit" table that would be more accurate to use for this.


SELECT     patient_name.*, patient_address.*, doctor.*
FROM         dbo.patient_name pn
INNER JOIN dbo.patient_address pa ON
    pa.patient_id = pn.patient_id
INNER JOIN dbo.doctor d ON
    d.doctor_id = pn.doctor_id

Too many errors, I don't know enough about SQL to interpret directions
