ANSI SQL

I have the following SQL:

select ptd.MPID, ptd.FIRST_NAME, ptd.LAST_NAME, ptd.DOB, ptd.SSN, ptd.ADMIT_STATUS_DESCR,
FD.FACILITYNO, FD.FACILITYNAME,
pdl.MD_FIRST_NAME, pdl.MD_LAST_NAME, pdl.MD_UPIN, mdd.LICENSE_NO, mdd.OFFICE_PHONE, ptd.NOTES
FROM
(

    (
    PT_DATA PTD LEFT JOIN FACILITY_DATA FD ON     PTD.HOME_LOCATION_ID = TO_NUMBER(FD.BILLINGLOCATION_ID)     AND FD.BILLINGLOCATION_ID IS NOT NULL     )
    LEFT JOIN PT_DATA_LOCATION PDL ON
    PTD.MPID = PDL.MPID AND PTD.HOME_LOCATION_ID = PDL.LOCATION_ID )
LEFT JOIN MD_DATA MDD ON PDL.NEPHROLOGIST_ID = MDD.ID ORDER BY PDL.FACILITY_NO, PTD.MPID; Can someone show me the translation of this query in Oracle SQL.

TIA
