MS SQL Trigger

Hey All!

Ok, new to MS SQL triggers...  SO, I need to try and do the following...

1: 2 tables SYS_USER, SERV_REQUEST, and SERV_NOTE
2: When a user is deleted from SYS_USER I need all refrences in SERV_REQUEST, and SERV_NOTE to be deleted as well.
3: I want the trigger to be on the SYS_USER table.

Here is the SQL for the tables and the joins...

SELECT
  user1229049.SYS_USER.ID_USER,
  user1229049.SYS_USER.ID_DISTRICT,
  user1229049.SYS_USER.ID_BUILDING,
  user1229049.SYS_USER.[USER_NAME],
  user1229049.SYS_USER.USER_PASSWORD,
  user1229049.SYS_USER.FIRST_NAME,
  user1229049.SYS_USER.LAST_NAME,
  user1229049.SYS_USER.EMAIL,
  user1229049.SYS_USER.RIGHTS,
  user1229049.SERV_REQUEST.ID_REQUEST,
  user1229049.SERV_REQUEST.ID_DISTRICT,
  user1229049.SERV_REQUEST.ID_BUILDING,
  user1229049.SERV_REQUEST.ID_ADMIN,
  user1229049.SERV_REQUEST.ID_TECHNICIAN,
  user1229049.SERV_REQUEST.ID_USER,
  user1229049.SERV_REQUEST.ID_PRIORITY,
  user1229049.SERV_REQUEST.ID_SUB_PRIORITY,
  user1229049.SERV_REQUEST.ID_ROOM,
  user1229049.SERV_REQUEST.ID_SERVICE_TYPE,
  user1229049.SERV_REQUEST.ID_SUB_SERVICE_TYPE,
  user1229049.SERV_REQUEST.ID_START_STATUS,
  user1229049.SERV_REQUEST.ID_SERVICE_STATUS,
  user1229049.SERV_REQUEST.ID_MODIFIED_LAST_BY,
  user1229049.SERV_REQUEST.INVENTORY_TAG,
  user1229049.SERV_REQUEST.REQUEST_POSTED_DATE,
  user1229049.SERV_REQUEST.REQUEST_REQUESTED_DATE,
  user1229049.SERV_REQUEST.REQUEST_OPEN_DATE,
  user1229049.SERV_REQUEST.REQUEST_MODIFIED_DATE,
  user1229049.SERV_REQUEST.REQUEST_CLOSED_DATE,
  user1229049.SERV_REQUEST.REQUEST_SERVICE_TIME_TOTAL,
  user1229049.SERV_REQUEST.ISSUE_DESCRIPTION,
  user1229049.SERV_NOTE.ID_NOTE,
  user1229049.SERV_NOTE.ID_SERV_REQUEST,
  user1229049.SERV_NOTE.ID_USER_TYPE,
  user1229049.SERV_NOTE.POSTED_DATE,
  user1229049.SERV_NOTE.NOTE
FROM
  user1229049.SYS_USER
  INNER JOIN user1229049.SERV_REQUEST ON (user1229049.SYS_USER.ID_USER = user1229049.SERV_REQUEST.ID_USER)
  INNER JOIN user1229049.SERV_NOTE ON (user1229049.SERV_REQUEST.ID_REQUEST = user1229049.SERV_NOTE.ID_SERV_REQUEST)

Here is the start of the trigger...

CREATE TRIGGER [SYS_USER (user1229049)].[SYS_USER_trd] ON [SYS_USER (user1229049)].[]
FOR DELETE
AS
BEGIN
  /* Trigger body */
END
GO

Any help would be great!
