I am using this query where I only want to exclude the rows with the date '01-JAN-00' but I am getting the same results without any changes or filtering.

```
SELECT PT.SITE_PROJECTS_ID, WS.WORKSTEP_ID, WS.WORKSTEP_NAME, PTT.TASK_STATUS, PTT.CREATED_DATE, PTT.COMPLETED_DATE,
    sp.SITE_PROJECTS_ID, spm.SITE_INFO_ID, si.SITE_ID, si.CITY, si.STATE, si.ZIP, si.COUNTY
    From site_projects sp
    Inner join site_projects_map spm on spm.site_projects_id = sp.site_projects_id
    Inner join site_info si on si.site_info_id = spm.site_info_id
    INNER JOIN PROJ_TRACKER PT on PT.site_projects_id = sp.site_projects_id
    INNER JOIN PROJ_TRACKER_TASKS PTT ON PT.PROJ_TRACKER_ID = PTT.PROJ_TRACKER_ID
    INNER JOIN WORKSTEPS  WS ON WS.WORKSTEP_ID = PTT.WORKSTEP_ID
    INNER JOIN WORKFLOW WF ON WF.WF_ID = WS.WF_ID
    WHERE PTT.COMPLETED_DATE <> '01-JAN-00'

```
