But it seems very slow and very complicated ,I want another one query using with connect by prior ..
Please help me.

[Oracle 8i] Need help pruning branches from a hierarchical query
My problem is that my hierarchical query seems only to trim out the values that don't meet my criteria, but still includes their children. When my query hits a record that does not meet my criteria, I want it to stop there. I've tried including the criteria in just the 'where' clause of the query, and have also put the criteria in the 'connect by' clause as well, but nothing has fixed it. Please keep in mind I'm using Oracle 8i, so I can't use some of the 'nicer' statements for hierarchical queries that they introduced in 9. I'm stuck with 'Start With...Connect By'.
I have sample tables/data that I can post if someone needs to see that to help me, but to start with, here's my current query:
SELECT *
FROM (
SELECT

) a
WHERE c_part_type = 'M'The outside criterion of part_type='M' isn't my problem. Where I'm actually seeing my issue rear its ugly head is in the criterion:
(c_bill.view_code IN ('M','G'))What I'll have happen is that one of the children or grandchildren of the part number I'm querying for (my parameter), will be of some view code that's not 'M' or 'G'. In my sample data below, I have a level 4 part that is part of the 'H' view code, which I don't want, nor do I want it's children. However, its child is in the 'G' view code, and my query returns it anyway.
In my sample data below, I'm assuming that the parameter = 'XYZ-100'

Ah, just spotted it's a delete statement - you won't be able to do it using subquery factoring in Oracle.
I had a go at trying to convert for you, but notice that you reference the cte from inside the cte... I can only assume you have a table called cte too...
DELETE FROM dbo.tb1
WHERE col1 = 12
OR col2 IN (SELECT col1 FROM cte)

ORACLE 9I의 HIERARCHICAL QUERY의 ORDER SIBLINGS BY CLAUSE
제품 : ORACLE SERVER
작성날짜 : 2003-10-22
(V9I) Oracle 9i의 Hierarchical query의 ORDER SIBLINGS BY CLAUSE
===============================================================
PURPOSE
이 문서는 Oracle 9i의 new feature인 ORDER SIBLINGS BY 절을
Hierarchical query에 사용하는 예를 통하여 특정 컬럼을 기준으로
Ordering된 형태로 display하는 방법을 보여준다.
Explanation & Example
Hierarchical query를 구현할 때 ORDER BY 절을 사용하는 것은
Oracle 7.1 버젼부터 가능한 것이었다.
그러나, 순서대로 ordering되지 않고 특정 컬럼(emp table의 ename)을
기준으로 ordering하기를 원한다면 <Bulletin:10373>처럼 procedure를
작성하여야만 하였다.
그러나, Oracle 9i 에서는 ORDER BY 절 대신에 ORDER SIBLINGS BY 절을
사용할 수 있어 user-defined stored procedure를 만들 필요가 없게 되었다.
1) Ordering 하기 전의 emp table의 Hierarchical query
SQL> @a
ename EMPNO MGR JOB
KING 7839 PRESIDENT
JONES 7566 7839 MANAGER
SCOTT 7788 7566 ANALYST
ADAMS 7876 7788 CLERK
FORD 7902 7566 ANALYST
SMITH 7369 7902 CLERK
BLAKE 7698 7839 MANAGER
ALLEN 7499 7698 SALESMAN
WARD 7521 7698 SALESMAN
MARTIN 7654 7698 SALESMAN
TURNER 7844 7698 SALESMAN
ename EMPNO MGR JOB
JAMES 7900 7698 CLERK
CLARK 7782 7839 MANAGER
MILLER 7934 7782 CLERK
14 rows selected.
Ordering 하기 전의 a.sql 은 다음과 같다.
col ename format a25
col empno format 99999
col mgr format 99999
col job format a15
select rpad(' ', LEVEL*5) || ename "ename", empno, mgr, job
from emp
start with job='PRESIDENT'
connect by prior empno=mgr;
2) 9i의 new feature인 Hierarchical query를 사용하여 Ordering한 경우
SQL> @new_a
ename EMPNO MGR JOB
KING 7839 PRESIDENT
BLAKE 7698 7839 MANAGER
ALLEN 7499 7698 SALESMAN
JAMES 7900 7698 CLERK
MARTIN 7654 7698 SALESMAN

ename EMPNO MGR JOB
SMITH 7369 7902 CLERK
SCOTT 7788 7566 ANALYST
ADAMS 7876 7788 CLERK
14 rows selected.
Ordering하기 위해 사용한 new_a.sql 은 다음과 같다.
col ename format a25
col empno format 99999
col mgr format 99999
col job format a15
select rpad(' ', LEVEL*5) || ename "ename", empno, mgr, job
from emp
start with job='PRESIDENT'
connect by prior empno=mgr
order siblings by ename;

<Bulletin:10373>Thanks to Kendenny, Boneist and Odie.
Got the point that "Order Siblings by clause" cannot be used with connect by query with analytical function, Thanks Kendenny.
Yes, I now use main query and subquery, however the subquery be just "connect by" and have the all html tags added in the main query.
The below query is working now.
SELECT
CASE WHEN LAG(mylevel,1,0) OVER (ORDER BY myrownum) >= mylevel THEN '<li>'
ELSE
CASE LEAD(mylevel) OVER (ORDER BY myrownum)
WHEN mylevel THEN
CASE WHEN myrownum = 1 THEN '<ul id="sidebarmenu1" '
ELSE '<ul'
END ||'><li>'
ELSE
CASE WHEN myrownum =1 THEN '<ul id="sidebarmenu1"'
ELSE '<ul '
END ||' ><li>'
END
END ||'<a href="'||
CASE WHEN link_url IS NOT NULL THEN
link_url||'title="'||menu_item||'"'
ELSE '#"' END ||
'><span>'||short_menu_item||'</span></a>'||
CASE mylevel - LEAD(mylevel,1,1) OVER (ORDER BY myrownum)
WHEN -1 THEN NULL
WHEN 0 THEN '</li>'
ELSE REPLACE(LPAD('*', myleveL-LEAD(mylevel,1,1) OVER (ORDER BY myrownum),'*'), '*','</li></ul></li>')
END ||
CASE WHEN LEAD(mylevel,1,0) OVER (ORDER BY myrownum) = 0 THEN '</ul>'
ELSE NULL END unordered_List,
menu_item, menu_id,
above_menu_id
FROM (
SELECT LEVEL mylevel, ROWNUM myrownum,daevmt.*
FROM dae_vs_my_tasks daevmt
CONNECT BY PRIOR daevmt.menu_id = daevmt.above_menu_id
START WITH daevmt.above_menu_id = 'TOPMENU'
ORDER SIBLINGS BY display_order
) t;
Odie, I tried altering the session for the flag, still the first query was not working.
Thanks again all for your great time in answering me. -
Hi,
I have a hierarchical query which takes 2 seconds to execute. I need to get this down to milli seconds.
The table has around 8000 records. The query will never return more than 20 or so records. There is only ever 2 levels to the query.
I am quite surprised at this because it is a very simple query no table joins etc and I would have though 8000 records was nothing for Oracle.
Select id, parent_id, col1, col2, col3, col4, col5, col6
from my_table
where id=500
start with parent_id is null
connect by prior id = parent_id;
I have even tried initializing the start with say with 0 and making it a not null column...... indexing the columns used in the start with + connect by
I have tried various indexing stratergies. Does anyone have any similar experience? I am using Oracle 9i.
Thanks in advanceHow can I utilise the above query in a view if at all? Will I be able to pass in differnt ID's to the START WITH...?Certainly, you can. For example, you can use packaged
public variable to pass a parameter or Oracle CONTEXT:
SQL> create or replace package pass_param is
2 empno emp.empno%TYPE;
3 function get_empno return emp.empno%TYPE;
4 end;
5 /
 
Package created.
 
SQL> create or replace package body pass_param is
2 function get_empno return emp.empno%TYPE
3 is
4 begin
5 return empno;
6 end;
7 end;
8 /

A help with a hierarchical query
I've got two tables:
FOLDERS where relevant fields are: folderId, parentFolderId, folderQuota
and DOCUMENTS where the relevant fields are: folderId, size
FOLDERS is hierarchical - parentFolderId of a child's folder is set to folderId of the parent
folderQuota is nullable (quota not set)
Now, I need to execute a query with the following recursive logic
<i>function calcQuota (folderIdpar, isFirstpar) {
if (not isFirstpar) and (folderQuota of folder with folderIdpar is not null) return folderQuota;
return size of all documents where folderId = folderIdpar + calcQuota (folderId of all children, false);
}</i>
(I hope the pseudocode is understandable - the query is executed as <i>calcQuota(originalFolderId, true)</i>).
Now, my question is if I can achieve it with a single hierarchical query, or if I have to implement it as a recursive stored procedure.
Thanks!
P.S. I'm using Oracle XE (10g)OK,
I will need to create it (in real life it is created by an application), so I hope I will make it correct. If not, it should be easy to fix.
create table folders (
folder_id number primary key
parent_folder_id number,
quota number
create table documents (
document_id number primary key
folder_id number,
size number
INSERT INTO folders (folder_id, quota) VALUES (1, 1);
INSERT INTO folders (folder_id, parent_folder_id, quota) VALUES (2, 1, 2);
INSERT INTO folders (folder_id, parent_folder_id) VALUES (3, 1);
INSERT INTO folders (folder_id, parent_folder_id, quota) VALUES (4, 2, 4);
INSERT INTO folders (folder_id, parent_folder_id) VALUES (5, 2);
INSERT INTO folders (folder_id, parent_folder_id, quota) VALUES (6, 3, 8);
INSERT INTO folders (folder_id, parent_folder_id) VALUES (7, 3);
INSERT INTO documents (document_id, folder_id, size) VALUES (1, 1, 16);
INSERT INTO documents (document_id, folder_id, size) VALUES (2, 2, 32);
INSERT INTO documents (document_id, folder_id, size) VALUES (3, 3, 64);
INSERT INTO documents (document_id, folder_id, size) VALUES (4, 3, 128);
INSERT INTO documents (document_id, folder_id, size) VALUES (5, 4, 256);
INSERT INTO documents (document_id, folder_id, size) VALUES (6, 5, 512);
INSERT INTO documents (document_id, folder_id, size) VALUES (7, 6, 1024);
INSERT INTO documents (document_id, folder_id, size) VALUES (8, 7, 2048);
running the query for folder_id = 1 should return 1 + 2 + 64 + 128 + 8 + 2048 = 2251
running the query for folder_id = 2 should return 4 + 512 = 516
I have decided for this data, because it allows to track what values (folder.quota or document.size) is included in the result.
(it is the knapsack problem - see http://en.wikipedia.org/wiki/Knapsack_problem)
P.S. I'm leaving for three weeks, so I will come back after that. -
Problem with different execution paths in hierarchical query
Hello,
I have problems with the following query:
SELECT DISTINCT P.ID FROM PRODUCTELEMENTIMPL P WHERE ( ( LABEL = 'SomeLabel' AND PRODUCTELEMENTTYPE = 'SomeText' AND ( STATE = 'created' OR STATE = 'stored' OR STATE = 'archived' OR STATE = 'archivedRestored' ) ) ) START WITH P.ID = 42 CONNECT BY PRIOR P.ID = P.PARENT
We have two databases (an Oracle 10g XE and Oracle10g Enterprise). In the XE Database the query is executed very fast, but in the main installation it takes minutes. If I "explain" the query I get two different execution paths:
The fast:

Roland SpatzeneggerHello,
thank you for your replies. The indices and table schemas are the "same", but only the content for the tables was mirrored.
We made some tests with dropping and/or analyzing the tables, but it didn't change anything.
The main problem is that the query takes 33s in the productive environment for searching in a couple of rows. At the moment it's faster to make
SELECT DISTINCT P.ID, P.STATE FROM PRODUCTELEMENTIMPL P WHERE ( ( LABEL = 'SomeLabel' AND PRODUCTELEMENTTYPE = 'SomeText' ) ) START WITH P.ID = 42 CONNECT BY PRIOR P.ID = P.PARENT
and to test in the application if the state-values match ;-)
If I add the hint /*+ no_filtering */ in the test environment, I get the same "slow" execution path as in the production environment. So the question is, what prevents the filtering in "connect by"?
(I think in the fast version it filters only the results of the hierarchical query, in the slow version it first filters the whole table and joins/merge it with the hierachical result).
bye

Hierarchical Query Duplication Issue
Hi All,
I am trying to create a tree structure for a "NOT SO" elegantly structured data(for tree type traversing). The below mentioned query is the sample of the data that I have in the real-time system.
The assumption & requirements to be considered are as follows:
1. The query with the rep data(i.e. first WITH clause query with 9 rows) is the master data that needs to be shown in hierarchical structure.
2. The query with the group data is joined with the rep data on GROUP_ID to get the tree structure be traversing on group_id and PARENT_GROUP_ID(i.e. Second WITH clause query)
The problem is I am getting 16 rows instead of 9(which are expected since the master rep data query has 9 rows). Some part of the Tress is getting wrongly duplicated.
Can anybody please point to me where I am making any mistake in the way this hierarchical query is written.

115The duplicates are caused by the rows in REP. So Oracle is doing what you are asking of it because there is nothing further to restrict the connection to make one branch of 2 unique from the other branch of 2 -
I'm trying to use a Hierarchical Query with table joins in the "FROM" clause. According to the documentation, this will work with Oracle 9i and above.
My problem is that in some queries, using the "JOIN" syntax works correctly but in others, it gives an "ORA-00928" message.
If I change the query that gives the error to use old style Oracle joins (using the where clause), the query works.
Can anyone help me to identify the problem?Here's the query. Again, note that if I use the old oracle join syntax (using where clause) it works:
select level
, biu.parent_part_no
, biu.parent_part_serial_no
, biu.comp_part_qty
, cpi.part_no
, cpi.serial_number
, cpi.trace_code
from bom.bom_instance_usage biu
join bom.bom_part_instance cpi
on cpi.bom_part_instance_key = iu.comp_part_instance_key
start with ( biu.parent_part_no = '123456'
and biu.parent_part_serial_no = '114' )
connect by ( biu.parent_part_no = prior cpi.part_no
and biu.parent_part_serial_no = prior cpi.serial_number ) -

Hi all,
I must be tired and cannot think clearly, so I'm a bit confused the following query.
The environment is still Oracle 9i:
Oracle9i Enterprise Edition Release 9.2.0.8.0 - 64bit Production
PL/SQL Release 9.2.0.8.0 - Production
CORE 9.2.0.8.0 Production
TNS for HPUX: Version 9.2.0.8.0 - Production
NLSRTL Version 9.2.0.8.0 - Production
Suppose that I have the following data:
with mydata as
select 1 code, null code_high, 'John' cname, 'Smith' csurname, 'X' resp from dual union all
select 2 code, 1 code_high, 'Bill' cname, 'White' csurname, null resp from dual union all
select 3 code, 2 code_high, 'Fred' cname, 'Reed' csurname, 'X' resp from dual union all
select 4 code, null code_high, 'Tim' cname, 'Hackman' csurname, 'X' resp from dual union all
select 5 code, 4 code_high, 'John' cname, 'Reed' csurname, null resp from dual union all
select 6 code, 5 code_high, 'Bill' cname, 'Hakcman' csurname, 'X' resp from dual union all
select 7 code, 6 code_high, 'Fred' cname, 'White' csurname, null resp from dual union all
select 8 code, 7 code_high, 'Bill' cname, 'Smith' csurname, null resp from dual union all
select 9 code, 8 code_high, 'Tom' cname, 'Reed' csurname, null resp from dual
select *
from mydata;
CODE CODE_HIGH CNAME CSURNAME RESP
1 John Smith X
2 1 Bill White
3 2 Fred Reed X
4 Tim Hackman X
5 4 John Reed
6 5 Bill Hakcman X
7 6 Fred White
8 7 Bill Smith
9 8 Tom Reed
This is a hierarchical query where code_high represent the father.
I need to find in the hierarchy the upper responsible level for each code.
Suppose that I want to find in the hierarchy the first one having resp='X'.
Running the following query I can find it for code = 9
select code, cname, csurname
from mydata
where resp = 'X'
and rownum = 1
connect by prior code_high = code
start with code = 9;
CODE CNAME CSURNAME
6 Bill Hakcman
Is there a way to get the whole list with the corresponding responsible.
Here is the expected output:
CODE CODE_HIGH CNAME CSURNAME RESP RESP_CODE RESP_NAME RESP_SURNAME
1 John Smith X 1 John Smith
2 1 Bill White 1 John Smith
3 2 Fred Reed X 3 Fred Reed
4 Tim Hackman X 4 Tim Hackman
5 4 John Smith 4 Tim Hackman
6 5 Bill Hakcman X 6 Bill Hakcman
7 6 Fred White 6 Bill Hakcman
8 7 Bill Smith 6 Bill Hakcman
9 8 Tom Reed 6 Bill Hakcman
Regards.
AlbertoHi Anar,
check my post and my expected output.
This is too simple and it is not what I need.
Your code is showing this output:
SS CODE CNAME CSURNAME RESP
1 1 John Smith X
1 3 Fred Reed X
1 4 Tim Hackman X
1 6 Bill Hakcman X
Actually the only way I have found (in Oracle 9i) is the following:
select code, code_high, cname, csurname, resp
, ( select code
from mydata
where resp='X'
and rownum=1
connect by prior code_high = code
start with code=a.code
) resp_code
, ( select cname
from mydata
where resp='X'
and rownum=1
connect by prior code_high = code
start with code=a.code
) resp_name
, ( select csurname
from mydata
where resp='X'
and rownum=1
connect by prior code_high = code
start with code=a.code
) resp_surname
from mydata a;
CODE CODE_HIGH CNAME CSURNAME RESP RESP_CODE RESP_NAME RESP_SURNAME
1 John Smith X 1 John Smith
2 1 Bill White 1 John Smith
3 2 Fred Reed X 3 Fred Reed
4 Tim Hackman X 4 Tim Hackman
5 4 John Reed 4 Tim Hackman
6 5 Bill Hakcman X 6 Bill Hakcman
7 6 Fred White 6 Bill Hakcman
8 7 Bill Smith 6 Bill Hakcman
9 8 Tom Reed 6 Bill Hakcman
But I don't like this.
Regards.

Hierarchical query to combine two groupings into one broad joint grouping
Hi there,
I would like to know if anyone knows a way to solve the problem below with a SQL querie, maybe using some hierarchical queries or window functions (or anything else in SQL for that matter).
My environment is:
Oracle Database 11g Release 11.2.0.2.0 - 64bit
The problem is this:
I have a list of items that are grouped together in two different grouping ways (two columns).
This gives the ability for items to be linked to other items in two ways:
1. Directly if both have same value on GROUP1 and/or GROUP2;
2. indirectly if they have an item in common with at least one match on either GROUP1 or GROUP2.
The idea is to start from this dataset:
WITH T AS
SELECT 1 AS ITEM_ID, 'A' AS GROUP1, 100 AS GROUP2 FROM DUAL UNION
SELECT 2 AS ITEM_ID, 'A' AS GROUP1, 100 AS GROUP2 FROM DUAL UNION
SELECT 3 AS ITEM_ID, 'A' AS GROUP1, 101 AS GROUP2 FROM DUAL UNION
SELECT 4 AS ITEM_ID, 'B' AS GROUP1, 100 AS GROUP2 FROM DUAL UNION
SELECT 5 AS ITEM_ID, 'B' AS GROUP1, 102 AS GROUP2 FROM DUAL UNION
SELECT 6 AS ITEM_ID, 'C' AS GROUP1, 103 AS GROUP2 FROM DUAL UNION
SELECT 7 AS ITEM_ID, 'D' AS GROUP1, 101 AS GROUP2 FROM DUAL
SELECT * FROM T;
And end up with this dataset with a one single joint grouping:
WITH T AS
SELECT 1000 AS JOINT_GROUP_ID, 1 AS ITEM_ID FROM DUAL UNION
SELECT 1000 AS JOINT_GROUP_ID, 2 AS ITEM_ID FROM DUAL UNION
SELECT 1000 AS JOINT_GROUP_ID, 3 AS ITEM_ID FROM DUAL UNION
SELECT 1000 AS JOINT_GROUP_ID, 4 AS ITEM_ID FROM DUAL UNION
SELECT 1000 AS JOINT_GROUP_ID, 5 AS ITEM_ID FROM DUAL UNION
SELECT 1000 AS JOINT_GROUP_ID, 7 AS ITEM_ID FROM DUAL UNION
SELECT 2000 AS JOINT_GROUP_ID, 6 AS ITEM_ID FROM DUAL
SELECT * FROM T;The relationships are:
Item 1 is linked to Item 2 by GROUP1 and GROUP2;
Item 1 is linked to Item 3 by GROUP1 only;
Item 1 is linked to Item 4 by GROUP2 only;
Item 1 is linked to Item 5 through Item 4 by GROUP1;
Item 1 is linked to Item 7 through Item 3 by GROUP2;
Item 6 is not linked to any other item since it does not match on GROUP1 nor GROUP2 with any other item.
NOTEs:
- JOINT_GROUP_ID values could be any sequential value. I used 1000 and 2000 just to avoid confusion with the other IDs and group values used to picture the problem.
- The level of relationship is not restricted to 2 like the example above. There could be deeper relationships.
This seems to me like something that could be solved with a hierarchical query, but I could not get my head around it to solve the problem.
Hope one of you guys can help me on this.
Chears.Hi Bruno,
You are correct. Frank's solution does not work. You can do this using CONNECT BY on smaller problems, but it will be very inefficient for larger problems wirth significant looping. I wrote a quick blog article on this subject after reading your question this morning. This is actually an example of a very general class of problems and I already had three SQL solutions. I'll put the CONNECT BY one here, and you can look at my blog if you want more details (I include a diagram so I can't just post it here).

Version: Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
Hello,
I'm hoping I can get help with a Hierarchical Query.
My base table contains Projects with a Group ID. Each Group can have the same Project Name so displaying the information in a Select List on an form for data entry can be very confusing. I'm hoping I can get a query that would produce the output below.
Please let me know if I haven't provided the necessary information.
The tables involved are:
CREATE TABLE projects
PROJECT_ID NUMBER,
PROJECT_NAME VARCHAR2(100),
GROUP_ID NUMBER
CREATE TABLE vertical_group
GROUP_ID NUMBER,
GROUP_NAME VARCHAR2(50)
The data is:
INSERT INTO projects(project_id,project_name,group_id)
VALUES (1,'Proj Grp 1',1);
INSERT INTO projects(project_id,project_name,group_id)
VALUES (2,'Proj Grp 1',1);
INSERT INTO projects(project_id,project_name,group_id)
VALUES (3,'Proj Grp 1',1);
INSERT INTO projects(project_id,project_name,group_id)
VALUES (4,'Proj Grp 1',1);
INSERT INTO projects(project_id,project_name,group_id)
VALUES (5,'Proj Grp 1',1);
INSERT INTO projects(project_id,project_name,group_id)
VALUES (6,'Proj Grp 2',2);
INSERT INTO projects(project_id,project_name,group_id)
VALUES (7,'Proj Grp 2',2);
INSERT INTO projects(project_id,project_name,group_id)
VALUES (8,'Proj Grp 2',2);
INSERT INTO projects(project_id,project_name,group_id)
VALUES (9,'Proj Grp 2',2);
INSERT INTO projects(project_id,project_name,group_id)
VALUES (10,'Proj Grp 3',3);
INSERT INTO projects(project_id,project_name,group_id)
VALUES (11,'Proj Grp 3',3);
INSERT INTO projects(project_id,project_name,group_id)
VALUES (12,'Proj Grp 3',3);
INSERT INTO vertical_group(group_id,group_name)
VALUES (1,'Group 1');
INSERT INTO vertical_group(group_id,group_name)
VALUES (2,'Group 2');
INSERT INTO vertical_group(group_id,group_name)
VALUES (3,'Group 3');
The desired output is:
Group 1

CONTAINS in hierarchical query
Hello friends!
I have a table that describes some tree:
CATEGORIES (cat_id NUMBER, parent_id NUMBER, title VARCHAR2,
description VARCHAR2);
The following query works fast:
SELECT count(*)
FROM categories
WHERE CONTAINS( title,'Moscow WITHIN description OR Moscow
WITHIN title', 1 ) > 0;
But the hierarchical query
SELECT count(*)
FROM categories
WHERE CONTAINS( title, 'Moscow WITHIN description OR Moscow
WITHIN title', 1 ) > 0
START WITH cat_id = 1 CONNECT BY PRIOR cat_id = parent_id;
works very slowly.
What’s wrong and what should I do?
Thank you!
Index is:
begin
ctx_ddl.create_preference('cat_lexer', 'BASIC_LEXER');
ctx_ddl.set_attribute ('cat_lexer', 'printjoins', '_-');
ctx_ddl.set_attribute ('cat_lexer', 'index_themes', 'NO');
ctx_ddl.set_attribute ('cat_lexer', 'index_text', 'YES');
end;
exec ctx_cd.Create_CDstore('categories_cdstore', 'categories')
exec ctx_cd.Add_Column ('categories_cdstore', 'title')
exec ctx_cd.Add_Column ('categories_cdstore', 'description')
create index categ_title_index on categories( title ) INDEXTYPE
IS ctxsys.context
PARAMETERS ('LEXER cat_lexer DATASTORE categories_cdstore
SECTION GROUP categories_cdstore MEMORY 50M');Thank you Thomas,
I tried to use subquery like this:
SELECT count(*)
FROM (SELECT cat_id, title, description
FROM categories
START WITH cat_id = 2 CONNECT BY PRIOR cat_id =
parent_id) c
WHERE CONTAINS( c.title,'Moscow WITHIN description OR Moscow
WITHIN title', 1 ) > 0;
It works more faster <0.5-1 min.> then that in my first post <5-
7 min.>, but still slow than I wish.
If I use normal index (WHERE title LIKE '%Moscow%' AND ...) the
answer is immediate in this query!!! Yo!
Is this an Oracle's bag or mine?
Indeed, I try to solve more complex task.
I have another table RESOURCES (cat_id, url, title) that is
detail of CATEGORIES table. Assosiation one-to-many
categories.cat_id = resources.cat_id.
SELECT COUNT(*)
FROM resources r, (
SELECT cat_id
FROM categories
START WITH cat_id = 2 CONNECT BY PRIOR cat_id =
parent_id) c
WHERE c.cat_id = r.cat_id
AND CONTAINS(title,'Moscow',2)>0;
Again this works more slowly than if I use NORMAL index. -

In Oracle, START WITH, CONNECT BY commands will give all the direct and indirect child records. Other way round, is they are command which gives all the parent records till the root? Please let me know. I am working on Oracle 9i Release 2.
