Thanks for the question regarding "connect by ", versi

c_NAME VARCHAR2(40),
c_ID VARCHAR2(10),
c_MGRID VARCHAR2(10),
c_MGRNAME VARCHAR2(40)
);
Typical Data is
insert into EMPINFO VALUES ('A','HR','','','JASON BICKER','0000001','','');
insert into EMPINFO VALUES ('A','HR','','','NANCY WALTER','0400001','0000001','JASON BICKER');
insert into EMPINFO VALUES ('','MF','NAN3005','WIN','NANCY WALTER','0400001','','');
insert into EMPINFO VALUES ('','MF','NAN3005','UNIX','NANCY WALTER','0400001','','');
insert into EMPINFO VALUES ('A','HR','','','ADAM BRYAN','0400002','0000001','JASON BICKER');
insert into EMPINFO VALUES ('','MF','BRY0034','WIN','ADAM BRYAN','0400002','','');
insert into EMPINFO VALUES ('A','HR','','','STING CORY','0400003','0400002','ADAM BRYAN');
insert into EMPINFO VALUES ('','MF','STI4040','UNIX','STING CORY','0400003','','');
For example I want to display all records of NANCY WALTER. The c_MGRID is blank for 2nd and 3rd
record of NANCY WALTER. Similar structure will follow for other records as well.
Regards,
Rao

This table is kind of a master table that includes employee and its manager and the
systems(Unix/Windows) and userids the employee has on it.
Nancy Walker has a manager whose c_MGRID is populated for the 1st row. But the 2nd and 3rd row of
Nancy Walker shows
the system and the userid's she has access to. c_MGRID of this 2nd and 3rd row is empty. Is it
possible to include these rows in the hierarchy as well similar to "start with .... connect by
prior"

need more details, can there be two (or zero, or more than two) records for nancy in there with
c_mgrid filled in? would they have the same value?

Reviewer: A reader
For a user
a) only one record wherver c_mgrid is filled. This will always be there when he/she joins the
company.
b) 0 or more records wherever c_mgrid is not filled. Rows will be there only if user has access to
any Windows/Unix/Mainframe systems and has an userid on it.

use this as your "source" to connect by on:
ops$tkyte%ORA10GR2> select c_name, max( c_mgrid) over (partition by c_name) mgrid
2 from empinfo;
C_NAME MGRID
