help to connect by query

I have a requirement where I need to find the parent ID, so I use connect by to find the answer, but there is a mistake I'm committed for which I need help

Table structure: -.

CREATE TABLE EMP

(NUMBER OF BOSS,

NUMBER OF EMP,

NUMBER OF TL);

Insert the script: -.

Insert into EMP (BOSS, EMP, TL)

values (1, -1, null);

Insert into EMP (BOSS, EMP, TL)

values (2, 1, 100);

Insert into EMP (BOSS, EMP, TL)

values (3, 1, 101);

Insert into EMP (BOSS, EMP, TL)

values (4, 1, 102);

Insert into EMP (BOSS, EMP, TL)

values (5, -1, null);

Insert into EMP (BOSS, EMP, TL)

values (6, 5, 201);

Insert into EMP (BOSS, EMP, TL)

values (7, 5, 202);

Insert into EMP (BOSS, EMP, TL)

values (226, -1, null);

Insert into EMP (BOSS, EMP, TL)

values (227, 226, null);

Insert into EMP (BOSS, EMP, TL)

values (228, 227, 726);

Insert into EMP (BOSS, EMP, TL)

values (227, 229, 724);

Insert into EMP (BOSS, EMP, TL)

values (230, 227, 725);

commit;

Up to now, what I've tried is

SELECT * FROM EMP

WHERE TL = 725

START WITH EMP = - 1

CONNECT BY THE BOSS BEFORE = EMP;

I expect output is

EMP BOSS TL

______________________________

227 226

Please correct me where exactly I make a mistake

Thank you

[8i] need help with hierarchical (connection by) query

First of all, I work in 8i.

My problem is, I get the error ORA-01437 message: cannot have join with CONNECT BY.
And the reason why I get this error because one of the criteria that I use to cut a few branches with is in another table... Is anyway to circumvent this? I tried a view online (but got the same error). I thought to use the connection by query views online and filtering off the coast of what I don't want in this way, but I don't know how to filter an entire branch...

Simplified data examples:

CREATE TABLE     bom_test
(     parent          CHAR(25)
,     component     CHAR(25)
,     qty_per          NUMBER(9,5)
);

INSERT INTO     bom_test
VALUES     ('ABC-1','101-34',10);
INSERT INTO     bom_test
VALUES     ('ABC-1','A-109-347',2);
INSERT INTO     bom_test
VALUES     ('ABC-1','ABC-100G',1);
INSERT INTO     bom_test
VALUES     ('ABC-1','1A247G01',2);
INSERT INTO     bom_test
VALUES     ('ABC-100G','70052',18);
INSERT INTO     bom_test
VALUES     ('ABC-100G','M9532-278',5);
INSERT INTO     bom_test
VALUES     ('1A247G01','X525-101',2);
INSERT INTO     bom_test
VALUES     ('1A247G01','1062-324',2);
INSERT INTO     bom_test
VALUES     ('X525-101','R245-9010',2);

CREATE TABLE     part_test
(     part_nbr     CHAR(25)
,     part_type     CHAR(1)
);

INSERT INTO     part_test
VALUES     ('ABC-1','M');
INSERT INTO     part_test
VALUES     ('101-34','P');
INSERT INTO     part_test
VALUES     ('A-109-347','P');
INSERT INTO     part_test
VALUES     ('ABC-100G','M');
INSERT INTO     part_test
VALUES     ('1A247G01','P');
INSERT INTO     part_test
VALUES     ('70052','P');
INSERT INTO     part_test
VALUES     ('M9532-278','P');
INSERT INTO     part_test
VALUES     ('X525-101','M');
INSERT INTO     part_test
VALUES     ('1062-324','P');
INSERT INTO     part_test
VALUES     ('R245-9010','P');

It's the questioning of base (with no pruning of branches):

SELECT     LEVEL
,     b.component
,     b.parent
,     b.qty_per
FROM     bom_test b
START WITH          b.parent     = 'ABC-1'
CONNECT BY PRIOR     b.component     = b.parent

The above query results:

      LEVEL COMPONENT                 PARENT                        QTY_PER
----------- ------------------------- ------------------------- -----------
      1.000 101-34                    ABC-1                          10.000
      1.000 A-109-347                 ABC-1                           2.000
      1.000 ABC-100G                  ABC-1                           1.000
      2.000 70052                     ABC-100G                       18.000
      2.000 M9532-278                 ABC-100G                        5.000
      1.000 1A247G01                  ABC-1                           2.000
      2.000 X525-101                  1A247G01                        2.000
      3.000 R245-9010                 X525-101                        2.000
      2.000 1062-324                  1A247G01                        2.000

9 rows selected.

.. .but I want to only the branches (children, grandchildren, etc.) the type of part of'm '.
for example:

      LEVEL COMPONENT                 PARENT                        QTY_PER
----------- ------------------------- ------------------------- -----------
      1.000 101-34                    ABC-1                          10.000
      1.000 A-109-347                 ABC-1                           2.000
      1.000 ABC-100G                  ABC-1                           1.000
      2.000 70052                     ABC-100G                       18.000
      2.000 M9532-278                 ABC-100G                        5.000

Hello

Difficult problem!

Sorry for the false leads I posted last night.
In Oracle 8.1, you can CONNECT BY first of all, in a view online and then to join her, but you can't do the reverse.
We can change the 3 query to get the desired results by replacing the external CONNECTION BY a series of analytical functions to locate all ancestors and finally SELECT a line only if all the ancestors had part_type = am'.

It's not pretty, but it works:

SELECT       component, parent, qty_per
--,       r_num, lvl
--,       SUM (ancestor_ok)
FROM        (       -- Begin in-line view to calculate ancestor_ok
       SELECT       m.*
       ,       CASE
                  WHEN c_num < lvl
                      THEN  LAG ( part_ok
                                  , r_num - NVL ( a_pos

                                      )
                            ) OVER ( PARTITION BY  c_num
                                             ORDER BY          r_num
                                     )

On 11 lines from the bottom, I assumed that the maximum depth of any node would be 10. If you do not higher that it should really be, or if you delete that WHEN the clause, then the query still works, it'll just be less effective.

This works for your sample data and some variations I've tried, including the case where a component has many parents. Sorry, I could not test it very carefully. Try it on some of your actual data, and let me know if there are problems.

I'll try to post a more detailed explanation later.
Basically, it works by capturing the results CONNECT BY in subquery h. Each line is identified solely by r_num, giving its place in CONNECT BY results.
In the subquery m, where most of the work takes place, it calculates the a_pos, the r_num of the ancestor of a node at a given level. That value is used in the LAG later function to see if the ancestor was part_type = am' or not. Only the lines where all the ancestors had part_type = am' are included in the final result set.

I did have the time to read the messages you and Dev published today. I'll try to do this and get back to you.

Once more remind the people responsible that the Oracle 8.1 was replaced 9 years ago. Whatever they save by not upgrading is offset by what you have to write and maintain much more complicated code, which in turn runs much, much slower than something on a more recent database.
The following works in Oracle 10 and I think it would work in Oracle 9, too:

SELECT     b.component, b.parent, b.qty_per
FROM     bom_test     b
JOIN     part_test    p     ON     b.component     = p.part_nbr
START WITH      b.parent     = 'ABC-1'
CONNECT BY     b.parent       = PRIOR b.component
     AND     PRIOR p.part_type = 'M'
;

It's 7 lines of code instead of about 65 years it takes to do the same in Oracle 8.1.

Help me with SQL Query to retrieve data from a view
Hello Guru,

I need help in my sql query.
I use SQL TeraData.
I want an Oracle result in the following form-

Open tickets
Open months failure / Repair Service s/o improvement request Total general
2009-01-2 4 4 5 15
2009-02 1 0 2 3 6
2009-03 4 1 2 2 9
Grand Total 7 5 8 10 30

I wrote the query as where - TIME_PERIOD, RQST_TYPE_DM and DEMAND_SUMMARY_FCT are the points of view and I extract the data from the views only.

Select NVL (CA. TIME_PERIOD. PERIOD_CD, 'Total') THAT year.
COUNT (CASE WHEN CA. RQST_TYPE_DM. RQSTTYP_DESC Like '% of Break' THEN 1 END) as BreakFix
COUNT (CASE WHEN CA. RQST_TYPE_DM. RQSTTYP_DESC as 'N/a', 1 END) by n/a
COUNT (CASE WHEN CA. RQST_TYPE_DM. RQSTTYP_DESC as 'Improvement' THEN 1 END) accessories
COUNT (CASE WHEN CA. RQST_TYPE_DM. RQSTTYP_DESC Like '% Service' THEN 1 END) as ServiceRequests
COUNT (CA. RQST_TYPE_DM. RQSTTYP_DESC) AS grand_total
FROM CA. TIME_PERIOD, CA. RQST_TYPE_DM, CA. DEMAND_SUMMARY_FCT
WHERE (CA. DEMAND_SUMMARY_FCT. RQSTTYP_ID = CA. RQST_TYPE_DM. RQSTTYP_ID)
AND (CASE
WHEN CA. DEMAND_SUMMARY_FCT. MONTH_ID = CA. TIME_PERIOD. PERIOD_ID, 1
WHEN {fn concat ({fn concat (SUBSTR (CA. TIME_PERIOD. {(PERIOD_CD, 3, 4),'-')}, SUBSTR (CA. TIME_PERIOD. PERIOD_CD, 7, 2))} BETWEEN ' 2009-01' AND ' 2009-03' THEN 1
WHEN CA. DEMAND_SUMMARY_FCT. RQSTTYP_ID = '1' then 1
END) = 1
GROUP BY ROLLUP (CA. TIME_PERIOD. PERIOD_CD)

After executing the query, I get the following error:
3076: syntax Error: Data Type 'Time' does not match a defined Type name.
:( Kindly help me with this and let me know where I'm wrong... Please.
Messages indicates something wrong with your data... It would seem that the data does not match your format mask.

Thus, the data or the format mask.

Help with making SQL query references to column aliases in the Case statement
I need help with a sql query that I'm trying. I can go about it the wrong way, but I would be grateful if I could get any suggestions on possible solutions. This is my query:

SELECT DISTINCT spriden_pidm, spriden_id id, spriden_last_name | ',' | spriden_first_name name,

CASE
WHEN rcresar_comm_code_01 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_01
WHEN rcresar_comm_code_02 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_02
WHEN rcresar_comm_code_03 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_03
WHEN rcresar_comm_code_04 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_04
WHEN rcresar_comm_code_05 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_05
WHEN rcresar_comm_code_06 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_06
WHEN rcresar_comm_code_07 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_07
WHEN rcresar_comm_code_08 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_08
WHEN rcresar_comm_code_09 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_09
WHEN rcresar_comm_code_10 IN ('268 ', '269', ' 270') THEN rcresar_comm_code_10
END acg_elig_comm_code

CASE
WHEN acg_elig_comm_code = ' 268' THEN 'rigorous HS course. "
WHEN acg_elig_comm_code = '269' THEN ' 2 or several AP or IB"
WHEN acg_elig_comm_code = '270' THEN 'NOC as possible ".
END comm_code_description

OF spriden, rcresar, rcrapp1

WHERE (rcresar_comm_code_01 IN ('268 ', '269', ' 270')

OR rcresar_comm_code_02 ('268 ', '269', ' 270')

OR rcresar_comm_code_03 ('268 ', '269', ' 270')

OR rcresar_comm_code_04 ('268 ', '269', ' 270')

OR rcresar_comm_code_07 ('268 ', '269', ' 270')

OR rcresar_comm_code_08 ('268 ', '269', ' 270')

OR rcresar_comm_code_09 ('268 ', '269', ' 270')

OR rcresar_comm_code_10 ('268 ', '269', ' 270'))

Rcresar_aidy_code = & aidy_code

AND rcrapp1_aidy_code = rcresar_aidy_code

AND rcrapp1_curr_rec_ind = 'Y '.

AND rcrapp1_seq_no = rcresar_seq_no

AND spriden_pidm = rcresar_pidm

AND rcrapp1_pidm = rcresar_pidm

AND spriden_change_ind IS NULL

ORDER BY name

The second case statement is where I don't know exactly what it takes to get what I want.

Output should be like:
spriden_pidm name ID acg_elig_comm_code comm_code_description
«0000000000', ' 1111111111 ","John Doe","268", «rigorous HS race"»

If I take the second case statement it works great except that I do not have my comm_code description column. My question is how can I use my first statement value box to determine this column? I think that I need a case statement as I have, but I don't know how to reference the value of acg_elig_comm_code. Any help would be greatly appreciated. Thank you.

Hello

You cannot use the alias column in the query, even where it is set (except in the ORDER BY clause).
You can set the alias in a subquery and then use it in a great query, like this:
```
WITH  sub_q  AS

    SELECT DISTINCT spriden_pidm,spriden_id id, spriden_last_name||', '||spriden_first_name name,

ORDER BY  name
```
Furthermore, you might think to rearrange your table, so that you do not have 10 columns (rcresar_comm_code_01, rcresar_comm_code_02,...) that essentially do the same thing. The usual way to handle this kind of one-to-many relationship is to have all rcresar_comm_codes in a separate table, one per line, with a pointer to the table where you have them now.

SQL query help (we connect by clause level)

Hi all
I have this application developed with data with the clause.

 With dat As
(
  select '@AAA @SSS @DDD' col1 from dual union all
  select '@ZZZ @XXX @TTT @RRR @ZZA' col1 from dual 
)
Select regexp_substr( col1 , '[^@][A-Z]+',1,level) Show from dat
connect by level  <= regexp_count(col1, '@');

Output current: -.

SHOW

1st row comes very well, but the next line data copy. And the number of total records = 30. I tried with some, but not worked.
Expected results: -.

SHOW
-----------------------
AAA

I need some changes on my request and I am not able to see that. So anyone can add to that or can also provide a different solution also.

Thank you!
Ashutosh

Thanks for providing the loan to the use of query. :)

Here's a solution :-(tested on 10 g, do not have 11 g at hand)

For 11g, just use regexp_count instead of functions of the length.

With dat As
(
  select '@AAA @SSS @DDD' col from dual union all
  select '@ZZZ @XXX @TTT @RRR @ZZA' col1 from dual
)
Select regexp_substr( col, '[^@][A-Z]+',1,level) Show from dat
connect by nocycle level  <= length(col) - length(translate(col, 'A@', 'A'))
       and col = prior col
       and prior sys_guid() is not null;

SHOW
------------------------

Clearly, I used cross join. But I want to get the same result with another way. I don't want to use cross join and Union

Please help me in this.
What you desire can be accomplished using the outer join partitioned.
The documentation shows an example of [url http://docs.oracle.com/cd/E11882_01/server.112/e26088/statements_10002.htm#i2177515] this way to fill the gaps in the data.

Here's how you can use it in your case:

I have redesigned weeks of date columns for the join which will probably perform better and can possibly use indexes.
I assume that you have no time portion in your supply_date data? If you do, then week_end will need to be modified.

Where the order-by Nick is like this:

ORDER BY fmev. ENTRY_SEQUENCE for the lowest level, but where there is a submenu, then include those to the right place!

My apologies for the fact I can't recreate the data here for use in the trial, but as I am using E-Bus tables, it is not so easy.

Any advice much appreciated.

Thank you

ORDER of brothers and SŒURS BY fmev.entry_sequence

Hello

Thanks for posting the CREATE TABLE and INSERT.
Please post instructions that work. Did you mean to add something at the beginning of all the statements that now begin with "VALUES"?
It seems that there are errors in the application, too.

Because I can not re - create your tables, I'll show what you can do with tables in the scott schema.
Let's say you have information about the Department, type of employment, date and salary, like this:
```
SELECT       d.dname
,       e.job
,       e.hiredate
,       e.sal
FROM       scott.dept     d
JOIN       scott.emp     e  ON   d.deptno     = e.deptno
ORDER BY  d.dname
,            e.job
;
```
Output:
```
DNAME          JOB       HIREDATE         SAL
-------------- --------- --------- ----------
ACCOUNTING     CLERK     23-JAN-82       1300
ACCOUNTING     MANAGER   09-JUN-81       2450
ACCOUNTING     PRESIDENT 17-NOV-81       5000
RESEARCH       ANALYST   19-APR-87       3000
RESEARCH       ANALYST   03-DEC-81       3000
RESEARCH       CLERK     23-MAY-87       1100
RESEARCH       CLERK     17-DEC-80        800
RESEARCH       MANAGER   02-APR-81       2975
SALES          CLERK     03-DEC-81        950
SALES          MANAGER   01-MAY-81       2850
SALES          SALESMAN  22-FEB-81       1250
SALES          SALESMAN  08-SEP-81       1500
SALES          SALESMAN  20-FEB-81       1600
SALES          SALESMAN  28-SEP-81       1250
```
and you want to summarize the data, showing the total salary for all those hired for the 2 exercises (July to June), like this:
```
DNAME          JOB         Y1_TOTAL   Y2_TOTAL
-------------- --------- ---------- ----------
ACCOUNTING     CLERK              0       1300
ACCOUNTING     MANAGER         2450          0
ACCOUNTING     PRESIDENT          0       5000
RESEARCH       ANALYST            0       3000
RESEARCH       CLERK            800          0
RESEARCH       MANAGER         2975          0
SALES          CLERK              0        950
SALES          MANAGER         2850          0
SALES          SALESMAN        2850       2750
```
Here, Y1_TOTAL means the fiscal year beginning July 1, 1980, and Y2_TOTAL refers to the fiscal year beginning July 1, 1981. If hiredate is not in one of these exercises, the line is ignored.

The Oracle 9 (and more) you can get these results like this:
```
VARIABLE     fy_begin     VARCHAR2 (20)
EXEC  :fy_begin := '07/01/1980';

WITH     years     AS
(
     SELECT     LEVEL     AS year_num
     ,     ADD_MONTHS ( TO_DATE (:fy_begin, 'MM/DD/YYYY')
                  , 12 * (LEVEL - 1)
                  )              this_year_begin
     ,     ADD_MONTHS ( TO_DATE (:fy_begin, 'MM/DD/YYYY')
                  , 12 *  LEVEL
                  )              next_year_begin
     FROM    dual
     CONNECT BY     LEVEL <= 2     -- Can be any positive integer
)
SELECT    d.dname, e.job
,       SUM (CASE WHEN year_num = 1 THEN e.sal ELSE 0 END)     AS y1_total
,       SUM (CASE WHEN year_num = 2 THEN e.sal ELSE 0 END)     AS y2_total
FROM       scott.dept     d
JOIN       scott.emp     e  ON   d.deptno    = e.deptno
JOIN       years          y  ON   e.hiredate  >= y.this_year_begin
                  AND     e.hiredate  <  y.next_year_begin
GROUP BY  d.dname, e.job
ORDER BY  d.dname, e.job
;
```
From Oracle 11, you can also use the SELECT... Function PIVOT. Whenever you have any questions, please say what version of Oracle you are using.

If you want more exercise, simply change the CONNECT BY clause and add another expression of the SUM (CASE...) by hand, SELECT clause.

In the above, query: fy_begin determines when to start exercising.
In your request, it looked like: fy_begin could be any date in the same year civil and July 1 of the calendar year (regardless of the question whether it was before or after: fy_begin) was the beginning of the year. If this is what you want, then instead of
: fy_begin above, use
"07/01 /' | SUBSTR (: fy_begin,-4)

connect by query, element need root for each line
Hello

I'm working on a hierarchical query using connection by front. Each node in the tree has two properties, a type and a sequence.

The table that contains the hierarchy has 4 fields:
element_type_from
element_sequence_from
element_type_to
element_sequence_to

Each child has a parent, a parent can have several childeren. For a map, the element_type_to and element_sequence_to fields are zero.

To generate a tree, you can run:
```
select element_type_to
,      element_sequence_to
from   element_hierarchy
start with element_type_from = [root_element_type]
       and element_sequence_from = [root_element_sequence]
connect by prior element_type_to = element_type_from
       and prior element_sequence_to = element_sequence_from
```
That works well... but... not only don't want child elements, I would like to return the sequence of element root for each child (in our table is a type of root element is always the same). There are several root elements and I want to create a list containing all the trees and each node in the tree must have its roots as well.

There is the possibility to use sys_connect_by_path. This returns the root, but also the full path to the current child. It also returns a varchar2, requiring to be substr-ed and to_number-ed to get the sequence... not nice.

warning, extremely ugly (but functional) code:
```
select element_type_to
,      element_sequence_to
,      to_number(substr(sys_connect_by_path(element_sequence_from ,','),2,instr(sys_connect_by_path(element_sequence_from ,',') ||',',',',2)-2)) root_sequence
from   element_hierarchy
start with element_type_from = [root_element_type]
       and element_sequence_from = ( select [root_element_sequence] from all_root_elements )
connect by prior element_type_to = element_type_from
       and prior element_sequence_to = element_sequence_from
```
There must be something simple I'm missing here! Can you help me?

Edit: Oops, the database version is 10.2.0.4.0
CONNECT_BY_ROOT maybe?
