Oracle Text query parser - sample code

I've posted a new entry on my "searchtech" blog which includes code for a "Google-like" query syntax parser:
https://blogs.oracle.com/searchtech/entry/oracle_text_query_parser
Currently it's just sample code, but if it goes down well we might include it, or something similar, in a future release of the product.
I'd very much welcome feedback on it, either here on the forum, or on the blog, or directly to me email address (which is included in the download file).
Thanks, everyone.

When I select the "open in browser" option for each now, I get formatted, readable code, which can easily be copied and pasted into a file without the extra txt extension, and I much prefer that. So, for me, that is a sufficient fix.
It seems like this is handy, virtually idiot-proof code, easy to create the package, easy to use it, and provides the Google-like search that users expect, without raising errors or producing unexpected results. Frequently, on the OraFAQ forums, where I am a moderator, when there are various ways to solve a problem and I provide a Text solution, the complaint is that it is too complicated to create all of the formatting to fix potential problems with user input. Your code solves that problem and I hope it will be included in the next version. If you don't mind, I will post an announcement in the OraFAQ Text forum with the permanent link that you provided.

Parse times in Oracle 11G

Has anyone else experienced extremely long parse times for Oracle 11G versus 10G? We are experiencing at least a 10 times increase in the parsing of our SQL statements. This is causing our customers to complain when running reports which contain several SQL statements that aren't in the SGA due to the infrequent use. I have opened a Service Request and development stated that this is to be expected with Oracle 11G due to the new optimizer features. I have tried to disable the features by settting the optimizer version to anything but 11G and no setting has helped. To make thing even worse, this increased parse time is on a new server that should be 2.5 times faster than the server that is running the 10G database. I do get at least a 2.5 times increase, larger if I/O intensive, in almost every other aspect of the database except for the parse times.

I wondered what the resolution was to this issue. We currently experiencing this will our Oracle 11.1.0.7 database with a small but important set of queries and it seems to be getting worse. We first noticed it with a query that went from taking 3.5 seconds to 7 seconds. A SQLTrace / TKProf revealed that 99% of the time was being spent during the parsing. A second similar query that brings in more data is taking around 1.5 minutes to parse then only a few seconds to actually execute. These are queries that are part of on online web transaction so this is not acceptable. We are able to replicate the behavior in multiple database instances.As a starting point it would be interesting to see the tkprof output from :
alter session set events '10046 trace name context forever, level 8';
+your select statement+
exitWhen posting the output, use the "code" tags (see below) to make the output readable.

DRG-50901: text query parser syntax error

The query
SELECT * FROM ij
where
CONTAINS (ij.summary, 'ATTENZIONE!') > 0 returns an error:
ORA-29902: error in executing ODCIIndexStart() routine
ORA-20000: Oracle Text error:
DRG-50901: text query parser syntax error on line 1, column 13
Why?
There is a TEXT index on the summary column:
CREATE INDEX IJL_SUMMARY_IX ON IJ
(SUMMARY)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('
    lexer           MITO_LEXER
    wordlist        DEFAULT_WORDLIST
    stoplist        IJL_STOPLIST
    storage         IJL_TEXT_STORAGE
    SYNC (EVERY "SYSDATE + 10/1440")')
PARALLEL ( DEGREE 4 INSTANCES 1 );where the MITO_LEXER is
BEGIN
CTX_DDL.create_preference ('mito_lexer', 'BASIC_LEXER');
CTX_DDL.set_attribute ('mito_lexer', 'INDEX_STEMS', 'ITALIAN');
-- MITO-318: search on Text Index for Asterisks
CTX_DDL.set_attribute ('mito_lexer', 'printjoins', '*');
END;
/

Because the exclamation mark ("!") is a reserved operator, meaning soundex, and must appear before the word it applies to.

Text query parser issue

Hello guys,
I rather need an advice and my experience with the Oracle forums has always been auspicious.
I am using jDeveloper 11gR2 and Oracle database 11.2.0.1. Running the following query I have a view object based on that query and a search form with results table.
SELECT
SEEKER.SEEKER_ID SEEKER_ID,
SEEKER.CV CV,
SCORE(1)
FROM
SEEKER
WHERE CONTAINS(CV, '<query>
<textquery lang="ENGLISH" grammar="context">' ||
GET_RELATED_CATEGORIES(:keyword) ||
'</textquery>
<score datatype="INTEGER"/>
</query>', 1) > 0
GET_RELATED_CATEGORIES is a function which returns concatenated strings querying some semantic data in my database. The problem is when GET_RELATED_CATEGORIES returns null the "text query parser" is throwing an exception (that is how it is supposed to act).
I am asking for any suggestions for the implementation of that functionality and will be really grateful. Shall I export the whole query in a remote procedure and maybe call it as a web service or there is any other better solution (maybe some checks).
Thank you in advance!

I see two possible ways you can try.
1. cause the function in a way that no null value is returned (return an empty string '')
2. put a nvl (get..., '') around the function

Can't convert oracle.xml.parser.DTD to oracle.xml.parser.v2.DTD.

I am getting the following Error while trying
to compile the SampleMain.java file(Generating an XML document from a given Employee.dtd).
I have set my classpath to use xmlparser.jar.
D:\XMls>javac SampleMain.java
SampleMain.java:65: Can't convert oracle.xml.parser.DTD to oracle.xml.parser.v2.DTD.

Would you check the java parser version you are using? If using java parser V2, the normal lib name is xmlparserv2.jar.

Query can run in Oracle 10g but very slow in 11g

Hi,
We've just migrated to Oracle 11g and we noticed that some of our view are very slow (it takes seconds in 10g and takes 30 minutes in 11g), and the tables are using the local table.
Do any of you face the same issue?
This is our query:
SELECT
A.wellbore
,a.depth center
,d.MD maxbc
,d.XDELT xbc
,d.YDELT ybc
,e.MD minac
,e.XDELT xac
,e.YDELT yac
from
table_A d,table_A e, table_B a
where a.wellbore = d.WELLBORE (+)
and a.wellbore = e.WELLBORE(+)
and d.MD = (select max(MD) from table_A b where b.MD < a.depth and
d.wellBORE = b.wellBORE)
and e.md = (select min(md) from table_A c where c.MD > a.depth and
e.wellBORE = c.wellBORE);

Thanks I will move to the correct one..
Rafi,
Build the Indexes and it is still slow. I am querying from a view from another database, which is in 10g instances.

Regarding Query/Where box in oracle forms

Hi,
I have a query regarding query/where box in oracle.
When I enter ":" in one of the field query box pops up and when I enter some query and press F12 to execute query.
The OK button has to be pressed twice to retrieve the result.
Can anyone please let me know why this is happening, instead of retreiving results at one go by pressing OK once.
When does query box pos up? I have to avoid hitting OK button on query box twice.
Thanks for your advice in advance.
Thanks,
KLC

Query DB2 tables from oracle using normal view

This is with regard to querying db2 tables using oracle views. The view is created using dblink. The querying is not an one time activity.querying will be done once in a day. Can i use normal view (will it work ) or should i use materialised view. will i be able to view the added records in db2 table using normal view?
thanks,
vinodh

Do you think the database link or remote database care whether the select SQL that hits it, comes from a PL/SQL procedure, a view, a materialised view, a job or whatever else? It has no idea what/who is behind that select SQL - and nor does it care.
As for the benefits of a view vs. a materialised view - that depends on the requirements for needing to use that foreign database's data in the local database.

Query Data from other Oracle Database into current

Hi all,
I have to query data from another oracle database into the current oracle database. Because the customer has standard edition, I cannot use a pipe. I tried "SELECT column_name FROM external_oracle_db.schema.table WHERE column_name = 'column_value';" Unfortunately this does not work.
Does anyone have a suggestion?
Thanks
Hans

Have you tried with Database links?
SELECT column_name FROM schema.table@external_oracle_db WHERE column_name = 'column_value';

Why don't you use ResultSetMetaData instead? If you need to parse the query string before executing it, probably you have to write your own parser.
