Working with hierarchy

Question

Hi,
I am working with hierarchy (using start with and connect by prior ) in order to built a "tree" of application jobs.
For each job , the hirarchy start with LEVEL 1 until level "n" .
In the example bellow i have built the hirarchy for job number 34461 , which have 4 LEVELs.
Of curse i have hundreds of jobs , but in order to keep the example simple i am showing only the values of one job.
I need your advise with the following issue:
In case that one of rows return the value "bz" at column mach_name , i need to retun the ENTIRE job hirarchy (in the example bellow - all the 11 rows)
in case that the value "bz" does not exists at column mach_name - non of the rows related to the specific job should be return.
Please advise.

Hi Ann,
The suggested solution is not completed bacuse it didnt take in consideration the fact that i have several hirarchy.
In order to make the test case easier to understand , i have created the following test case :
CREATE TABLE mytest
  JOB_NAME   VARCHAR2(64 BYTE)                  NOT NULL,
  JOID       NUMBER(10)                         NOT NULL,
  "LEVEL"    NUMBER,
  BOX_JOID   NUMBER(10),
  MACH_NAME  VARCHAR2(80 BYTE)
Insert into mytest (JOB_NAME, JOID, "LEVEL", BOX_JOID)
Values   ('Ys_Inv_Push_Load_Ctrl_tr_BOX', 31596, 1, 34461);
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID)
Values    ('Ys_Inv_Push_Load_Ctrl_tr', 31605, 2, 31596);
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID)
Values    ('Ys_Inv_BOX', 31586, 3, 31605);
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID, MACH_NAME)
Values    ('Ys_Inv', 31587, 4, 31586, 'bz');
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID, MACH_NAME)
Values    ('Ys_Inv_OK', 31588, 4, 31586, 'auto');
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID)
Values    ('E_Push_Trx_BOX', 31594, 3, 31605);
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID, MACH_NAME)
Values    ('E_Push_Trx', 31595, 4, 31594, 'cr');
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID, MACH_NAME)
Values    ('E_Push_Trx_OK', 31597, 4, 31594, 'auto');
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID)
Values    ('Ys_Load_Cntrl_tr_BOX', 31599, 3, 31605);
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID, MACH_NAME)
Values    ('Ys_Load_Cntrl_tr', 31600, 4, 31599, 'bz');
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID, MACH_NAME)
Values    ('Ys_Load_Cntrl_tr_OK', 31602, 4, 31599, 'auto');
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID)
Values    ('GetPRM.bat_BOX', 37583, 1, 37581);
Insert into mytest    (JOB_NAME, JOID, "LEVEL", BOX_JOID, MACH_NAME)
Values    ('GetPRM.bat', 37585, 2, 37583, 'ha');
COMMIT;
select * from mytest;
JOB_NAME                             JOID      LEVEL   BOX_JOID MACH_NAME
Ys_Inv_Push_Load_Ctrl_tr_BOX        31596          1      34461
Ys_Inv_Push_Load_Ctrl_tr            31605          2      31596
Ys_Inv_BOX                          31586          3      31605
Ys_Inv                              31587          4      31586 bz
Ys_Inv_OK                           31588          4      31586 auto
E_Push_Trx_BOX                      31594          3      31605
E_Push_Trx                          31595          4      31594 cr
E_Push_Trx_OK                       31597          4      31594 auto
Ys_Load_Cntrl_tr_BOX                31599          3      31605
Ys_Load_Cntrl_tr                    31600          4      31599 bz
Ys_Load_Cntrl_tr_OK                 31602          4      31599 auto
GetPRM.bat_BOX                      37583          1      37581               
GetPRM.bat                          37585          2      37583 ha           
13 rows selected.
The last TWO rows should NOT be return , beacuse the last hirarachy (identified by the fact that it start again with LEVEL 1) does not contain "bz"
values under column mach_name.
Please advise
Thanks
