Help with Oracle Text
Hello all,
Can someone point me in the right direction as to how to actually use this feature of Oracle? I've got a series of tables in my database that contain > 1 VARCHAR2 columns and one CLOB column. I need to be able to issue a query similar to this: select * FROM TABLE WHERE CONTAINS(*, 'Search Text') > 0. I want to be able to search all of the indexed columns in the table for the same text. If it finds the text in any of the columns, then return the row. I haven't yet been able to find any defacto document that shows me how to do this. It's been REALLY frustrating.
Thanks.
First of all, Text doesn't support a "contains(*,query)" syntax.
I don't know how familiar are you with the features so I'll recommend looking at the code samples:
http://otn.oracle.com/products/text/x/Samples/index.html
An then into the different datastore types to see which one will fit your requirements.

Hello,
I have the following table:
create table table1(col1 clob)
In columns COL1 I store some XML with the following structure:
<ROW>
<NAME>....</NAME>
<COL1><VAL>...</VAL><VAL>....</VAL></COL1>
<COL2>....</COL2>
</ROW>
So I compare two indexes:
1. Simple index:
create index myindex on table1(col1)
indextype is ctxsys.context
parameters ('datastore ctxsys.default_datastore
filter ctxsys.null_filter
section group ctxsys.auto_section_group')
2. Another index with stop sections, I think it will allow to increase performance and decrease index's size as I will index only NAME tag.
begin
ctx_ddl.create_section_group('xmldatagroup', 'AUTO_SECTION_GROUP');
ctx_ddl.add_stop_section('xmldatagroup', 'VAL');
ctx_ddl.add_stop_section('xmldatagroup', 'COL1');
ctx_ddl.add_stop_section('xmldatagroup', 'COL2');
end;
create index myindex on table1(col1)
indextype is ctxsys.context
parameters ('datastore ctxsys.default_datastore
filter ctxsys.null_filter
section group xmldatagroup')
But when I compared these indexes I found that sizes are the same and the token's table DR$MYINDEX$I for the second index contains tokens from tags from stop sections however in documentation I see:
Stop sections, empty tags, processing instructions, and comments are not indexed.
Is anybody know what's wrong with my code or stop section is just logical declaration for using on the query's execution step?I'm not sure why your stop sections aren't working, but if you know the layout of the document I would recoomend using explcitly-defined field sections rather than auto_section_group.
This will be a lot more efficient for querying.
It will still index the data outside of the <NAME> section, though as part of the "default" section. If you don't want to index that, you could use a user_datastore to remove all the stuff apart from what you want to index.

- I find if such search is too slow, I have studied but have not found a way to accelerate your returns faster results like?
- I want to improve performance query is how?
- I hope people will help me solve
Thanks every body!Hi,
what is the plan for this query? I think it is maybe a full scan on the table and it uses not even the indexes. Is it possible to rewrite the query to use union?

Problem with oracle text indexes during import
We have a 9.2.0.6 database using oracle text features on a server with windows 2000 5.00.2195 SP4.
We need to export its data ( user ARIANE only ) and then import the result into another 9.2.0.6 database.
The import never comes to an end.
The only way to make it work is to use the "indexes=n" clause.
Then ( without the indexes ), we tried to create manually the oracle text indexes.
We get this error :
CREATE INDEX ARIANE.DOSTEXTE_DTTEXTE_CTXIDX ON ARIANE.DOSTEXTE (DTTEXTE)
INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS('lexer ariane_lexer stoplist ctxsys.default_stoplist storage ariane_storage');
ORA-29855: erreur d'exécution de la routine ODCIINDEXCREATE
ORA-20000: Erreur Oracle Text :
DRG-10700: préférence inexistante : ariane_lexer
ORA-06512: à "CTXSYS.DRUE", ligne 157
ORA-06512: à "CTXSYS.TEXTINDEXMETHODS", ligne 219
We then tried to uninstall Oracle text and install it ( My Oracle Support [ID 275689.1] ). The index creation above still fails.
We also checked our Text installation and setup through My Oracle Support FAQ ( ID 153264.1 ) and everything seems ok.
Do we have to create some ARIANE* lexer preferences through specific pl/sql ( ctx_report* ? ) before importing anything from the ARIANE user ?
What do we need to do exactly when exporting data with oracle text features from one database to another given we used to restore the database through a copy of the entire windows files ?
Is there a specific order to follow to succeed an import ?
Thank you for your help.
Jean-michel, Nemours, FRANCEHi
index preferences are not exported, ie ariane_lexer + ariane_storage, only the Text index metada, thus the DRG-10700 from index DDL on target/import DB.
I recommend to use ctx_report.create_index_script on source/export DB, see Doc ID 189819.1 for details, export with indexes=N and then create text indexes manually after data import.

we are design a simple document management application using psp with oracle text.
we can query on index and finding the record and display the result on browser page.
but we can't take document link on the same browser page. So we can't take document itself.
We are using Oracle database release 1 text
Thanks for your help.Sorry. The correct one is http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/text.920/a96517/acase.htm#620714

I need help with my text tone. I have ring tone no text tone. I have a 4s.
Hi Sarar2333! Let's get your text tones working again!
Here's a link with instructions how to enable and change your alert sounds for your text/notification settings on your iPhone 4S: http://vz.to/1stiF8a. You can ensure text tones are enabled by selecting a tone in the "Text Tone" setting. Let me know how that works out for you. Thanks!

Help with oracle 11g pivot operator
i need some help with oracle 11g pivot operator. is it possible to use multiple columns in the FOR clause and then compare it against multiple set of values.
here is the sql to create some sample data
create table pivot_data ( country_code number , dept number, job varchar2(20), sal number );
insert into pivot_data values (1,30 , 'SALESMAN', 5000);
insert into pivot_data values (1,301, 'SALESMAN', 5500);
insert into pivot_data values (1,30 , 'MANAGER', 10000);
insert into pivot_data values (1,301, 'MANAGER', 10500);
insert into pivot_data values (1,30 , 'CLERK', 4000);
insert into pivot_data values (1,302, 'CLERK',4500);
insert into pivot_data values (2,30 , 'SALESMAN', 6000);
insert into pivot_data values (2,301, 'SALESMAN', 6500);
insert into pivot_data values (2,30 , 'MANAGER', 11000);
insert into pivot_data values (2,301, 'MANAGER', 11500);
insert into pivot_data values (2,30 , 'CLERK', 3000);
insert into pivot_data values (2,302, 'CLERK',3500);
using case when I can write something like this and get the output i want
select country_code
,avg(case when (( dept = 30 and job = 'SALESMAN' ) or ( dept = 301 and job = 'SALESMAN' ) ) then sal end ) as d30_sls
,avg(case when (( dept = 30 and job = 'MANAGER' ) or ( dept = 301 and job = 'MANAGER' ) ) then sal end ) as d30_mgr
,avg(case when (( dept = 30 and job = 'CLERK' ) or ( dept = 302 and job = 'CLERK' ) ) then sal end ) as d30_clrk
from pivot_data group by country_code;
output
country_code D30_SLS D30_MGR D30_CLRK
1 5250 10250 4250
2 6250 11250 3250
what I tried with pivot is like this I get what I want if I have only one ( dept,job) for one alias name. I want to call (30 , 'SALESMAN') or (301 , 'SALESMAN') AS d30_sls. any help how can I do this
SELECT *
FROM pivot_data
PIVOT (SUM(sal) AS sum
FOR (dept,job) IN ( (30 , 'SALESMAN') AS d30_sls,
(30 , 'MANAGER') AS d30_mgr,
(30 , 'CLERK') AS d30_clk
this is a simple example .... my real life scenario is compliated with more fields and more combinations .... So something like using substr(dept,1,2) won't work in my real case .
any suggestions get the result similar to what i get in the case when example is really appreciated.Hi,
Sorry, I don't think there's any way to get exactly what you requested. The values you give in the PIVOT ... IN clause are exact values, not alternatives.
You could do something like this to map all alternatives to a common value:
WITH got_dept_grp AS
SELECT country_code, job, sal
, CASE
WHEN job IN ('SALESMAN', 'MANAGER') AND dept = 301 THEN 30
WHEN job IN ('CLERK') AND dept = 302 THEN 30
ELSE dept
END AS dept_grp
FROM pivot_data
SELECT *
FROM got_dept_grp
PIVOT ( AVG (sal)
FOR (job, dept_grp)
IN ( ('SALESMAN', 30)
, ('MANAGER' , 30)
, ('CLERK' , 30)
;In your sample data (and perhaps in your real data), it's about as easy to explicitly define the pivoted groups individually, like this:
WITH got_pivot_key AS
SELECT country_code, sal
, CASE
WHEN job = 'SALESMAN' AND dept IN (30, 301) THEN 'd30_sls'
WHEN job = 'MANAGER' AND dept IN (30, 301) THEN 'd30_mgr'
WHEN job = 'CLERK' AND dept IN (30, 302) THEN 'd30_clrk'
END AS pivot_key
FROM pivot_data
SELECT *
FROM got_pivot_key
PIVOT ( AVG (sal)
FOR pivot_key
IN ( 'd30_sls'
, 'd30_mgr'
, 'd30_clrk'
;Thanks for posting the CREATE TABLE and INSERT statements; that really helps! -
Hi,
I need some help... if someone can help its great.
I need to make a statement in Oracle SQL that read data from a file and insert in a Oracle Database ... if someone can show me the syntax of it i appreciate..
ThanksOkay, I see you followed the advice in that other thread and started a new post for you question. Congratulations. Your next lesson in forum etiquette is to give your posts a more relevant subject. Pretty much everybody who posts here needs help with oracle; if they need help with cooking catfish they've come to the wrong place.
It that other thread I suggested using SQL*Loader or External Tables might be a more suitable solution. Find out more.

How to get exact match when working with Oracle Text?
Hi,
I'm running Oracle9i Database R2.
I would like to know how do I get exact match when working with Oracle Text.
DROP TABLE T_TEST_1;
CREATE TABLE T_TEST_1 (text VARCHAR2(30));
INSERT INTO T_TEST_1 VALUES('Management');
INSERT INTO T_TEST_1 VALUES('Busines Management Practice');
INSERT INTO T_TEST_1 VALUES('Human Resource Management');
COMMIT;
DROP INDEX T_TEST_1;
CREATE INDEX T_TEST_1_IDX ON T_TEST_1(text) INDEXTYPE IS CTXSYS.CONTEXT;
SELECT * FROM T_TEST_1 WHERE CONTAINS(text, 'Management')>0;
The above query will return 3 rows. How do I make Oracle Text to return me only the first row - which is exact match because sometimes my users need to look for exact match term.
Please advise.
Regards,
Jap.But I would like to utilize the Oracle Text index. Don't know your db version, but if you slightly redefine your index you can achieve this (at least on my 11g instance) :
SQL> create table t_test_1 (text varchar2(30))
2 /
Table created.
SQL> insert into t_test_1 values ('Management')
2 /
1 row created.
SQL> insert into t_test_1 values ('Busines Management Practice')
2 /
1 row created.
SQL> insert into t_test_1 values ('Human Resource Management')
2 /
1 row created.
SQL>
SQL> create index t_test_1_idx on t_test_1(text) indextype is ctxsys.context filter by text
2 /
Index created.
SQL> set autotrace on explain
SQL>
SQL> select text, score (1)
2 from t_test_1
3 where contains (text, 'Management and sdata(text="Management")', 1) > 0
4 /
TEXT SCORE(1)
Management 3

Note
- dynamic sampling used for this statementJust read that you indeed mentioned your db version in your first post.
Not sure though if above method is already available in 9i ...

Huge Databases to be indexed with Oracle Text?
Is there anybody with experience with Oracle Databases with several TB and an fulltext index with Oracle Text? Are there any success stories by oracle?
Oracle Text, data load by partitation, async refresh index.
Hi Gurus,
Here I got a question,
Serniro:
A table with 2 partitions, text index created.
When I load data into 1st partition, performance good.
Sync partion text index, performance good.
Then I load data into 2nd partition, it's so slow.
My question is,
How to disable/offline 2nd partition text index?
Sync it after I loaded 2nd partition data. -

only return 2 row but should return 3I just noticed that I forgot to use an empty stoplist, so I have added that to the revised example below. Otherwise, it uses a default stoplist that would not index common single-letter words like A and I.
1. Whtat is Just search on single character 'L'? It give me error.
Since it uses the NEAR operator, searching for just one letter causes incomplete syntax, asking it to search for L near a missing second value. So, I have added additional code to allow for just one letter.
2. How do I do auto refresh on this index on datastore?
If I add "sync (on commit)" it does not refresh the previously set token.
Sync(on commit) does synchronize so that the data is immediately searchable. You have to either optimize or rebuild or drop and recreate the index to condense the rows in the domain index table.
3.lastly explanation of
<seq>NEAR((' || letters_func (:search_string) || '),1,TRUE)</seq>
<seq>NEAR((' || letters_func (:search_string) || '),100,TRUE)</seq>
<seq>NEAR((' || letters_func (:search_string) || '),100,FALSE)</seq>
why 100 true and 100 false
100 is just a default value that I used for the second parameter of near, indicating how close the letters need to be to each other. True and False are values for the third parameter of near, indicating whether or not the letters must be in the same order or not. So, it returns the results in the order of first those that are very close to one another and in the same order, then those that may be further away but in the same order, then those that may be further away and in any order.

but here I have a problem. how can i run the below select for my above query?
SELECT *

here what can I do the value for :I_opensearchText ? confused.
please help me..!!

Performance issue with Oracle Text index
Hi Experts,
We are on Oracle 11.2..0.3 on Solaris 10. I have implemented Oracle Text in our environment and I am facing a strange performance issue that is happening in our environment.
One sql having CONTAINS clause is taking forever - more than 20 minutes and still does not complete. This sql has a contains clause and an exists clause and a not exists clause.
Now if I remove the exists clause and a not exists clause , it completes fast. but with those two clauses it is just taking forever. It is late night so i am not able to post the table and sql query details and will do so tomorrow but based on this general description, are there any pointers for me to review?
sql query doing fine:
SELECT
U.CLNT_OID, U.USR_OID, S.MAILADDR
FROM
access_usr U
INNER JOIN access_sia S
ON S.USR_OID = U.USR_OID AND S.CLNT_OID = U.CLNT_OID
WHERE U.CLNT_OID = 'ABCX32S'
AND CONTAINS(LAST_NAME , 'TO%' ) >0
--sql query that hangs forever:
SELECT
U.CLNT_OID, U.USR_OID, S.MAILADDR
FROM
access_usr U
INNER JOIN access_sia S
ON S.USR_OID = U.USR_OID AND S.CLNT_OID = U.CLNT_OID
WHERE U.CLNT_OID = 'ABCX32S'
AND CONTAINS(LAST_NAME , 'TO%' ) >0
and exists (--one clause here wiht a few table joins)
and not exists (--one clause here wiht a few table joins);
--Now another strange thing I found is if instead of 'TO%' in this sql, if I were to use 'ZZ%' or 'L1%' it works fast but for 'TO%' it goes slow with those two exists not exists clauses!
I will be most thankful for the inputs.
OrauserNHi Barbara,
First of all, thanks a lot for reviewing the issue.
Unluckily making the change to empty_stoplist did not work out. I am today copying the entire sql here that has this issue and will be most thankful for more insights/pointers on what can be done.
Here is the entire sql:
SELECT U.CLNT_OID,
U.USR_OID,
S.EMAILADDRESS,
U.FIRST_NAME,
U.LAST_NAME,
S.JOBCODE,
S.LOCATION,
S.DEPARTMENT,
S.ASSOCIATEID,
S.ENTERPRISECOMPANYCODE,
S.EMPLOYEEID,
S.PAYGROUP,
S.PRODUCTLOCALE
FROM ACCESS_USR U
INNER JOIN
ACCESS_SIA S
ON S.USR_OID = U.USR_OID AND S.CLNT_OID = U.CLNT_OID
WHERE U.CLNT_OID = 'G39NY3D25942TXDA'
AND EXISTS
(SELECT 1
FROM ACCESS_USR_GROUP_XREF UGX
INNER JOIN ACCESS_GROUP RELG
ON RELG.CLNT_OID = UGX.CLNT_OID
AND RELG.GROUP_OID = UGX.GROUP_OID
INNER JOIN ACCESS_GROUP G
ON G.CLNT_OID = RELG.CLNT_OID
AND G.GROUP_TYPE_OID = RELG.GROUP_TYPE_OID
WHERE UGX.CLNT_OID = U.CLNT_OID
AND UGX.USR_OID = U.USR_OID
AND G.GROUP_OID = 920512943
AND UGX.INCLUDED = 1)
AND NOT EXISTS
(SELECT 1
FROM ACCESS_USR_GROUP_XREF UGX
INNER JOIN
ACCESS_GROUP G
ON G.CLNT_OID = UGX.CLNT_OID
AND G.GROUP_OID = UGX.GROUP_OID
WHERE UGX.CLNT_OID = U.CLNT_OID
AND UGX.USR_OID = U.USR_OID
AND G.GROUP_OID = 920512943
AND UGX.INCLUDED = 1)
AND CONTAINS (U.LAST_NAME, 'Bon%') > 0;
Like I said before if the EXISTS and NOT EXISTS clause are removed it works in sub-second. But with those EXISTS and NOT EXISTS CLAUSE IT TAKES ANY WHERE FROM 25 minutes to more than one hour.
NOte also that it was not TO% but Bon% in the CONTAINS clause that is giving the issue - sorry that was wrong on my part.
Also please see below the ORACLE TEXT index defined on the table ACCESS_USER:
--definition of preferences used in the index:
SET SERVEROUTPUT ON size unlimited
WHENEVER SQLERROR EXIT SQL.SQLCODE
DECLARE
v_err VARCHAR2 (1000);
v_sqlcode NUMBER;
v_count NUMBER;
BEGIN
ctxsys.ctx_ddl.create_preference ('cust_lexer', 'BASIC_LEXER');
ctxsys.ctx_ddl.set_attribute ('cust_lexer', 'base_letter', 'YES'); -- removes diacritics
EXCEPTION
WHEN OTHERS
THEN
v_err := SQLERRM;
v_sqlcode := SQLCODE;
v_count := INSTR (v_err, 'DRG-10701');
IF v_count > 0
THEN
DBMS_OUTPUT.put_line (
'The required preference named CUST_LEXER with BASIC LEXER is already set up');
ELSE
RAISE;
END IF;
END;
DECLARE
v_err VARCHAR2 (1000);
v_sqlcode NUMBER;
v_count NUMBER;
BEGIN
ctxsys.ctx_ddl.create_preference ('cust_wl', 'BASIC_WORDLIST');
ctxsys.ctx_ddl.set_attribute ('cust_wl', 'SUBSTRING_INDEX', 'true'); -- to improve performance
EXCEPTION
WHEN OTHERS
THEN
v_err := SQLERRM;
v_sqlcode := SQLCODE;
v_count := INSTR (v_err, 'DRG-10701');
IF v_count > 0
THEN
DBMS_OUTPUT.put_line (
'The required preference named CUST_WL with BASIC WORDLIST is already set up');
ELSE
RAISE;
END IF;
END;
--now below is the code of the index:
CREATE INDEX ACCESS_USR_IDX3 ON ACCESS_USR
(FIRST_NAME)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('LEXER cust_lexer WORDLIST cust_wl SYNC (ON COMMIT)');
CREATE INDEX ACCESS_USR_IDX4 ON ACCESS_USR
(LAST_NAME)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('LEXER cust_lexer WORDLIST cust_wl SYNC (ON COMMIT)');
The strange thing is that, like I said, If I remove the exists clause the query returns very fast. Also if I modify the query to use only one NOT EXISTS clause and remove the other EXISTS clause it returns in less than one second. Also if I remove the EXISTS clause and use only the NOT EXISTS clause it returns in less than 4 seconds. But with both clauses it runs forever!
When I tried to get dbms_xplan.display_cursor to get the query plan (for the case of both exists and not exists clause in the query), it said that previous statement's sql id was 0 or something like that so that I was not able to see the query plan. I will keep trying to get this plan (it takes 25 minutes to one hour each time but will get this info soon). Again any pointers are most helpful.

Searching from beginning of a line/string with Oracle Text ...
Oracle Database 10.2.0.3, Solaris
Hi,
what sounds very easy with the LIKE operator seems to be impossible with the Oracle Text Operator Contains ;
Searching for 'Deutsche%' results with LIKE ->
'Deutsche Bank'
'Deutsche Post'
'Deutsche Oracle Community'
But with Contains-Operator which is token based the result is following ('$Deutsche%')
'Deutsche Bank'
'Armin Deutscher'
We want to get results starting with 'Deutscher...' But with Contains and some configuration i did not find a way. Combining LIKE with Contains did not help too because Contains expands the word in more instances then LIKE.
Indexed Columns are varchar2 typed
any idea?
kind regards
Karl

KeyHave a look at the reports help for the purpose header and trailer sections. Here is an exert:
"Report sectioning enables you to define multiple layouts in the same report, each with a different target audience, output format, page layout, page size, or orientation. You can define up to three report sections, each with a body area and a margin area: the names of the sections are Header, Main, and Trailer. By default, a report is defined in the Main section. In the other sections, you can define different layouts, rather than creating multiple separate reports. If you wish, you can use the margin and body of the Header and Trailer sections to create a Header and Trailer page for your reports."
