Multiple columns in connect by prior

Hi,
I have data something like below
SKU:
ITEM LOC PARENT_ITEM PARENT_LOC
NULL NULL A 001
A 001 NULL NULL
A 001 NULL NULL
NULL NULL D 002
D 002 NULL NULL
D 002 NULL NULL
And I need output like this
ITEM LOC PARENT_ITEM PARENT_LOC
NULL NULL A 001
B 001 A 001
C 001 A 001
NULL NULL D 002
E 002 D 002
F 002 D 002
And I tried it with connect by prior.
Select CONNECT_BY_ROOT as item,loc,parent_item,parent_loc FROM
sku
start with parent_item is null and parent_loc is null
connect by prior parent_item = item and parent_loc = loc
But I am getting only parent record not others.
ITEM LOC PARENT_ITEM PARENT_LOC
A NULL A 001
D NULL D 002
I should apply CONNECT_BY_ROOT and connect by PRIOR on set (like item at loc).
Please help..
Thanks...

Hi ,
Can some one please explain me how to comprehend/understand multiple conditions in connect by prior conditions with some example data.
I am creating a table like this

Can some one please explain me comprehension of both these query or give me a example where i can understand multiple connect by prior conditions
Thanks

the ftvorgn table is hierachical in nature, where the forusor table is not . The FORUSOR table holds the name and a hiearchy node from the FTVORGN TABLE within it.
I have spent several hours trying to get a query to work. I just don't see what my error is? if you follow the trail thus far you will notice that the FORUSOR table contains a value of '1006' in the FORUSOR_ORGN_CODE column. However everytime I run this query i get duplicate rows in return.

             AND   PRIOR FTVORGN_COAS_CODE = FTVORGN_COAS_CODE
             AND   FTVORGN_EFF_DATE <= TO_DATE(sysdate)

             AND   FTVORGN_NCHG_DATE > TO_DATE(sysdate);
I't trying to basically get all the predecessor notes for everynote on FORUSOR but i keep ending up with duplicate rows.
I should end up with something similar to this.
sorry for the format of the results I'm not very good at formatting.

on column FORUSOR_ORGN_CODE in the FORUSOR table there is a node value that corresponds to a value on FTVORGN. However , that value could have a FTVORGN_ORGN_CODE_PRED which basically says I'm reporting to this value.
if I basically run this query for a node you can see the hierachy.
SELECT FTVORGN_ORGN_CODE,
             FTVORGN_DATA_ENTRY_IND,
             FTVORGN_STATUS_IND,
             LEVEL, FTVORGN_ORGN_CODE_PRED
     FROM    FTVORGN2
CONNECT BY PRIOR FTVORGN_ORGN_CODE = FTVORGN_ORGN_CODE_PRED
             AND   PRIOR FTVORGN_COAS_CODE = FTVORGN_COAS_CODE
             AND   FTVORGN_EFF_DATE <= TO_DATE(sysdate)
             AND   FTVORGN_NCHG_DATE > TO_DATE(sysdate)
START WITH       FTVORGN_ORGN_CODE = '1006'
             AND   FTVORGN_COAS_CODE = 'D'
             AND   FTVORGN_EFF_DATE <= TO_DATE(sysdate)
             AND   FTVORGN_NCHG_DATE > TO_DATE(sysdate);
I now need to pass the orgn code from forusor to this query to get all the ftvorgn_orgn_code that this user technically has reporting to him on FORUSOR.
so for example user jma337 has org
1006 in forusor
when i run the query i should get
jma337 2027
jma337 2028
jma337 5275 etc.
Reason in because these are all predecessors of 1006 which in this case would essentially be our level 1.
I need to do this all the FORUSOR_ORGN_CODE this user has recorded to him on FORUSOR.

Switching to four digit years (to make the query work)
with

Query tuning for query using connect by prior

I have written following query to fetch the data. The query is written in this format because there are multiple rows, which make one recrd and we need to bring that record into one row.
For one CAT(commented here), this query takes around 4 minutes and fetches 6900 records but when it runs for 3 CAT, it takes 17 mins.
I want to tune this as this has to run for 350 CAT values.
It is doing FTS on the main table. I tried to use different hints like PARALLEL, APPEND (in insert) but nothing worked.
The cost of the query is 51.
Any help/suggestions will be appreciated.
SELECT DISTINCT MIN(SEQ) SEQ,
PT, APP, IT, LR, QT,CD, M_A_FLAG,
STRAGG(REM) REM, -- aggregates the data from different columns to one which is parent
CAT
FROM (WITH R AS (SELECT CAT, SEQ, PT, M_A_FLAG, IT, LR,QT,CD, REM, APP
FROM table1
WHERE REC = '36' AND M_A_FLAG = '1'
--AND CAT = '11113')
SELECT CAT, SEQ,
CONNECT_BY_ROOT PT AS PT,
CONNECT_BY_ROOT APP AS APPL,
M_A_FLAG,
CONNECT_BY_ROOT IT AS IT,
CONNECT_BY_ROOT LR AS LR,
CONNECT_BY_ROOT QT AS QT,
CONNECT_BY_ROOT CD AS CD,
REM
FROM R A
START WITH PT IS NOT NULL
CONNECT BY PRIOR SEQ + 1 = SEQ
AND PRIOR CAT = CAT
AND PT IS NULL)
GROUP BY PT, APP, IT,LR, QT, CD, M_A_FLAG, CAT
ORDER BY SEQ;
Thanks.

Can anyone please help with a Connect by PRIOR sql?

Hi,
I am not so well versed in Oracle analytic functions and am having trouble with a sql.
Oracle Version: 9.2.0.1.0
I have a tree table storing heirarchies upto 4 levels.
create table FAMILY_TREE
TREE_ID NUMBER not null,
PARENT_ID NUMBER,
NAME VARCHAR2(100)
I know that using a CONNECT BY PRIOR, I can find out who the previous ancestar is.
select
f.tree_id TreeId,
f.parent_id ParentId,
f.Name Name
from family_tree f
connect by
prior f.tree_id = f.parent_id
start with f.parent_id is null
I need to display all the ancestars in a single line (in different columns), which is where I am stumped.
I need the output, in different columns as :
Joe Jack Harry Rick Ned
Bascially, I need to display in a single row, all the ancestars.
I tried to use joins but it was very very slow due to the fact that I had to perform multiple joins.
Can anyone please point me in the right direction?
Data:
insert into FAMILY_TREE (TREE_ID, PARENT_ID, NAME)
values (1, null, 'Joe');
insert into FAMILY_TREE (TREE_ID, PARENT_ID, NAME)
values (2, 1, 'Jack');
insert into FAMILY_TREE (TREE_ID, PARENT_ID, NAME)
values (3, 2, 'Harry');
insert into FAMILY_TREE (TREE_ID, PARENT_ID, NAME)
values (4, 3, 'Rick');
insert into FAMILY_TREE (TREE_ID, PARENT_ID, NAME)
values (5, 4, 'Ned');

This may give you a start

Result to be in multiple columns instead of one

Hi,
i have used the below sql :
select parent_id, max(sys_connect_by_path(name,'^')) History
from (select parent_id, name, row_number() over (partition by parent_id order by name) rn
from notes )
start with rn = 1
connect by prior rn = rn-1
and prior parent_id = parent_id
group by parent_id
order by parent_id
this gets me the 'HISTORY' row returned in a single column. Problem is if i have 5 HISTORY notes, they all appear in same column with delimiter ^.
Please help to modify query as to get History as multiple columns instead of 1
Below is example of sample data returned , NOTE: history could contain any amount of rows.
ID     HISTORY
1     ^TT updates requested^TT updates requested^Update on TT #104836
2     ^Call back actioned^Delivery Update^Internation Dialing ^TT Follow up (147023)
3     ^Queried poor signal strength
Idea case would be :
ID     HISTORY HISTORY1 HISTORY2
1     TT updates requested TT updates requested Update on TT #104836

Hi,
You might want to leave the results as one long string, but just add some spacing.
Right now you're using
sys_connect_by_path(name,'^')and getting output like
1 ^TT updates requested^TT updates requested^Update on TT #104836
2 ^Call back actioned^Delivery Update^Internation Dialing ^TT Follow up (147023)
3 ^Queried poor signal strengthwhich is as hard to read as an OTN posting that doesn't use \ tags. Naturally you're not going to insult your uses by asking them to read something like that.
If you use this instead:REPLACE ( sys_connect_by_path ( RPAD (name, 32)
               ,'^'
     , '^'
then the output will look like this:TT updates requested          TT updates requested          Update on TT #104836
Call back actioned          Delivery Update               Internation Dialing           TT Follow up (147023)
Queried poor signal strength

Drill-down to multiple columns at same time

Hello,
Is it possible to simultaneously drill down to multiple columns on the same level with one click? I have several attributes that the user will want to see together at all times, so I want to be able to drill from level1 to level2a,2b, and 2c with one click.
Thanks,
Elliot

This drilling down to all the levels may not be available with the OBIEE drill level based hierarchy feature OOTB but as an alternative you can try this at you DB level to create a hierarchy within you data using START WITH and CONNECT BY PRIOR to generate the parent->child levels hierarchy within the view instead of creating multiple hierarchical columns.
Or may be you can try to create separate columns in a table for each hierarchy level. That table could either be in the database or be a logical one in the repository. For example:
Level 1 Level 2 Level 3 Description
1 2A 3A
1 2A 3B
1 2B 3A
1 2B 3B
etc
You then create separate reports for each level, so one report has only level1 in it for this dimension, another report has levels 1 an 2 and a third report has levels 1, 2 and 3 etc.
In each report you put an action link on the levels' cells so that if you click on them you drill up or down by displaying a new report with either less or more level columns.
Hope this helps. Pls mark if it does.
Thanks,
SVS

Merge multiple columns into single column?

Hi,
I need to execute queries dynamically and return the values. I need to fetch the values of the queries in single column only by concatenating the multiple columns. I cannot use PL/SQL in my scenario.
is there any way to execute a query and the result will be fetched in single column (values of multiple columns needs to be concatenated)?
Thanks,
Raja.

How to get the root node for a child using connect by prior

Hi,
I searched at many places to do this but not able to get the exact o/p sp posting my question here.
I have a table with parent_id and child_id columns. The levels of this parent_child can be many but my aim is to find the ultimate parent ( dont know the right term)
like if I have a child_node= xyz and its parent= pqr and its parents=lmn which might be ultimate parent which doesnt have any further parent.
So if i start with child_code= "xyz" then i should get the parent as "lmn" and not the immediate parent "pqr".
Please help.
Thanks,
Aashish

To find the Parent on emp table:
select empno,ename,level
from emp
where level=3
start with empno=7934
connect by empno= prior mgrTo find the Child on emp table:
select empno,ename,level
from emp
where level=1
start with empno=7934
connect by prior empno= mgrBut you need to know the level or position to specify the level of parent or child. But there are some other possible options available if we can know the requirement properly.

How to insert from one table to another (multiple columns to single column)

I want to insert data from table1 into table2 and the data looks in 3 columns as below
Table1
RepNm ObjNm DbNm
123     abc def
456     def xyz
789     123 456
and the data in table2 should be display as
Table 2
ObjNm
123
456
789
abc
def
xyz
the dupes should get eliminated and only the distinct values should be inserted into a single column in table2 from multiple columns in table1

How do you want to handle nulls? If there is a null in any value of a column, do you want to insert it?
Then,
WITH T
     AS (SELECT LEVEL colnum
           FROM DUAL
         CONNECT BY LEVEL <= 3)
SELECT DECODE (colnum, 1, RepNm, 2, ObjNm, 3, DbNm) as ObjNm
FROM table1, T;if you dont want to insert nulls then,
WITH T
     AS (SELECT LEVEL colnum
           FROM DUAL
         CONNECT BY LEVEL <= 3)
SELECT DECODE (colnum, 1, RepNm, 2, ObjNm, 3, DbNm) AS ObjNm
FROM table1, T
WHERE DECODE (colnum, 1, RepNm, 2, ObjNm, 3, DbNm) = DECODE (colnum, 1, RepNm, 2, ObjNm, 3, DbNm)G.

Connect by prior in Oracle 11g

I am upgrading an application from 9i to 11g and I've been told that the connect by prior sql is broken. While I am waiting for the example and the error message, is 11g pickier about looping than 9i was? Can someone point me to some documentation on 10 or 11 changes to hierarchical queries?
Thanks in advance.

Hi, Jim,

While I am waiting for the example and the error message, is 11g pickier about looping than 9i was? Can someone point me to some documentation on 10 or 11 changes to hierarchical queries?There were a lot of improvements to CONNECT BY in Oracle 10, including CONNECT BY NOCYCLE (for working with loops), the CONNECT_BY_ROOT operator, and pseudo-columns CONNECT_BY_ISCYCLE and CONNECT_BY_ISLEAF. Look them up in the SQL Language manual for your version.
I don't know of any improvements or changes to CONNECT BY in Oracle 11.
Oracle 11.2 has recursive WITH clauses, that can do everything that CONNECT BY does, and more. Some things in 11.2 are simpler and more efficient using CONNECT BY, others are better done using recursive WITH clauses.
Everything that CONNECT BY did in earlier versions, it does in Oracle 11, as well. If you have a CONNECT BY query that works in Oracle 9, it should work in Oracle 11, without any changes, though there might be better ways to get the same results in Oracle 11.
Whenever you have a question, post youir code, and whatever is necessary to run it, including CREATE TABLE and INSERT statments for a little sample data. Post the results you want from that sample data, and an explanation of how you get those results from that data.
Always say which version of Oracle you're using, e.g. 11.2.0.2.0. The difference between 11.1 and 11.2 may be very significant in this case.
See the forum FAQ {message:id=9360002}

Connect by prior problem with order by

Hi,
I and using connect by prior within a query on Oracle 8 and would like to order the results within the parent levels.
All the documentation that I have read shows that in Oracle 9i there is an option to say order siblings by which looks like what I need, but this does not work on Oracle 8.
Can anyone tell me how I can order the children within the parents without changing the tree structure?
I have also tried SYS_CONNECT_BY_PATH and I just get an error saying that it is an invalid column name,

Karen, see here for a dicussion on how to order the siblings in a pre-9i environment:

I have a table containing events backup.
i want to list the hierarchy within that backup oreder by the time_stamp for all levels.
create table BCK_EVENTS
bck_backup_id           NUMBER(9) default 0 not null,
event_id                   NUMBER(15) default 0 not null,
event_name              NVARCHAR2(100) default ' ' not null
time_stamp               NUMBER(9) default 0 not null,
parent_event            NUMBER(15) default 0 not null,
add constraint BCK_EVENTS_PK primary key (BCK_EVENT_ID, EVENT_ID); // event_id is not unique can be under one or more backup id'sthis is not a tree with one root, there is more than one event in the root level (level 1).
example:
Event Name      Time         level   <- time is numeric but for easier reading.
*Event A          10:00         1
   *Event C        10:30         2

    *Event M      16:57          3
   *Event G        20:20         2What i tried was :
select lpad( '*', level*2 ) || event_id,event_name,time_stamp,parent_event,level from bck_events
     where bck_event_id=100031
     start with parent_event is null
    connect by prior event_id = parent_eventand there are two problems with it.
1. it's not ordered even when i added an Index (parent_event,time_stamp) and try to hint it.
2. it returns loads of multiple rows.
hope it's clear enough. I thank for any help.

this is not a tree with one root, there is more than one event in the root level (level 1).Is it a forest, that is, a set of trees?

*Event M      16:57          3
*Event G        20:20         2
That seems to be a forest, that is, every row has 0 or 1 parent, and no row is its own ancestor.
What i tried was :
select lpad( '*', level*2 ) || event_id,event_name,time_stamp,parent_event,level from bck_events
where bck_event_id=100031
start with parent_event is null
connect by prior event_id = parent_event
and there are two problems with it.
1. it's not ordered even when i added an Index (parent_event,time_stamp) and try to hint it.Depending on your data, you may just need to add
ORDER SIBLINGS BY time_stampat the end, after the CONNECT BY clause.
If you need rows sorted by time_stamp under their roots, but otherwise without regard to the hierarchy, then use CONNECT_BY_ROOT.
2. it returns loads of multiple rows.Again, it depends on your data. I'll bet you need something more in the CONNECT BY clause, but I can't tell what without some sample data and an exxplanation of how you gett the results you posted from that data. The fact that bck_event_id is part of the primary key makes me suspect that maybe bck_event_id needs to be somewhere in the CONNECT BY clause, but that's just a wild guess.
hope it's clear enough. I thank for any help.As mentioned before, see the forum FAQ {message:id=9360002}

CONNECT BY PRIOR statement issue

Hi,
I'm using the below select query to build a relationship b/w ID & parent_id, but HANA studio is throwing a syntax error. I don't see a problem around the syntax. Please throw some light's here.
SELECT * FROM "SIVA_TEST"."Core_Competency" START with "Competency_ID"=1
CONNECT BY PRIOR "Competency_ID" = "Parent_Competency_ID" ;
Error:
Could not execute 'SELECT * FROM "SIVA_TEST"."Core_Competency" START WITH "Competency_ID"='1' CONNECT BY PRIOR ...' in 170 ms 563 µs .
SAP DBTech JDBC: [257] (at 46): sql syntax error: incorrect syntax near "START": line 2 col 1 (at pos 46)
Table struct:
create column table "SIVA_TEST"."Core_Competency"("Competency_ID" integer,
"Competency_Name" varchar(200),
"Competency_description" varchar(1000),

"start_date" date,
primary key("Competency_ID"));
Thanks,

CONNECT BY PRIOR question

Hi, I have following problem
Table TMP contains following data
ID PID
1
2 1
3 2
select t.id
from tmp t
where level=(select max(level)
from tmp t2
connect by prior t2.pid=t2.id
start with t2.id=&ID)
connect by prior t.pid=t.id
start with t.id=&ID
Select returns 1 when ID=3
Is there a way to write select so that it returns value for first node
and value of ID used in select?
Something like
select value_of_ID
,t.id
from tmp t
start with t.id=&ID
so I could use group by on first column (group by value_of_ID)
Following select would not satisfy:
select &ID
,t.id
from tmp t
start with t.id=&ID

I would suggest something more straightforward:
select :startnode, id
from tmp
where pid is null
start with id = :startnode
connect by prior pid = id;The WHERE clause will limit the result to just the top level - no need for a subquery or aggregate functions.
