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

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.

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.

What does it mean when the usecounts of Parse Tree for a view is incrementing when a select query is issued against the view?

I'm using SQL Server 2008 R2 (10.50.4033) and I'm troubleshooting an issue that a select query against a specific view is taking more than 30 seconds consistently.   The issue just starts happening this week and there is no mass changes in data.
The problem only occur if the query is issued from an IIS application but not from SSMS. One thing I noticed is that sys.dm_exec_cached_plans is returning 2 Parse Tree rows for the view - one created when the select query is issued
1st time from the IIS application and another one created when the same select query is issued 1st time from SSMS.   The usecounts of the Parse Tree row for the view (the IIS one) is increasing whenever the select query is issued.  The
usecounts of the Parse Tree row for the view (the SSMS one) does not increase when the select query is issued again.
There seems to be a correlation between the slowness of the query and the increasing of the usecounts of the Parse Tree row for the view.
I don't know why there is 2 Parse Tree rows for the view. There is also 2 Compiled Plan rows for the select query.
What does the Parse Tree row mean especially the usecounts column?

>> The issue just starts happening this week and there is no mass changes in data.
There might be a mass changes in the execution plan for several reason without mass changes in data
If you have the old version and a way to check the old execution plan, and compare to the new one, that this should be your starting point. In most cases you don't have this option and we need to monitor from scratch.
>> The problem only occur if the query is issued from an IIS application but not from SSMS.
This mean that we know exactly what is the different and you can compare both execution plan. once you do it, you will find that they are no the same. But this is very common issue and we can know that it is a result of different SETting while connecting
from different application. SSMS is an external app like any app that you develop in Visual studio but the SSMS dose not use the Dot.Net default options.
Please check this link, to find the full explanation and solutions:
http://www.sommarskog.se/query-plan-mysteries.html
Take a look at sys.dm_exec_sessions for your ASP.Net application and for your SSMS session.
If you need more specific help, then we need more information and less stories :-)
We need to see the DDL+DML+Query and both execution plans
>> What does the Parse Tree row mean
I am not sure what you mean but the parse tree represents the logical steps necessary to execute the query that has been requested. you can check this tutorial about the execution plan: https://www.simple-talk.com/sql/performance/execution-plan-basics/ or
this one: http://www.developer.com/db/understanding-a-sql-server-query-execution-plan.html

Either the statistics are not up to date, the data values are skewed or you have some optimizer parameter set to none default to force index access.

Checking text query validity without actually running the query: ideas?

Hi,
I would like to implement a sort of function that does a preliminary check on the validity of the search string and ideally this function should work with both CTXCAT and CONTEXT indexes (and grammars).
Initially I thought that CTXQUERY.EXPLAIN function could do this for me, but, unless I am missing something, it only works with CONTEXT indexes and it doesn't accept a string containing a text query rewrite using CTXCAT grammar (it throws DRG-11119: operation is not supported by this index type).
Plan B would be to create an empty table with a CONTEXT index and then run the query either with the CONTEXT grammar or the CTXCAT grammar via query rewrite and if the query runs, returning no rows, presumably fast enough for this purpose, then the query string is assumed to be valid.
What I don't like much about plan B is the need for an additional table plus the "dummy" context indexes just to perform the parsing of the text query, but so far I didn't come up with more brilliant ideas.
Any thoughts?
Am I missing something that does the magic without hassle?
Thanks
Flavio

Under normal circumstances I wouldn't do this, as you say I'd just run the query and catch the error, but I need to do this inside a report refresh performed via AJAX (using Oracle Apex) and the catch is that when such refresh fails owing to a syntax error, the partial refresh mechanism of APEX becomes broken, so even if you amend the query and submit a new valid string, it won't show up any more.
That's why I need to be sure that the string is valid before running the query, hence the syntax checking function.
The google-style parser sounds interesting, may be I can try to implement it in a future release of my app!
Thanks
Flavio

Parsing Issue in Filter For Date Format

Hi Folks,
I am having Parsing Issue on "Key Date" Object in Universe. See the Error and Code below for your review
Error: Parse Failed: Exception: DBD, The value entered is not valid. It must adhere to one of the following formats.
YYYYMMDD
DD.MM.YYYYState:N/A
Code:
<OPERATOR VALUE="AND"><OPTIONAL><FILTER KEY="0I_DAYIN"><CONDITION OPERATORCONDITION="Between"><CONSTANT TECH_NAME="@Prompt('Day Interval From','A','Calendar Day\LovDay IntervalBase',mono,primary_key)"/><CONSTANT TECH_NAME="@Prompt('Day Interval To','A','Calendar Day\LovDay IntervalBase',mono,primary_key)"/></CONDITION></FILTER></OPTIONAL><FILTER KEY="0P_KEYDA"><CONDITION OPERATORCONDITION="Equal"><CONSTANT TECH_NAME="@Prompt('Key Date','D',,mono,free)"/></CONDITION></FILTER></OPERATOR>
This universe is created by someone else and client need to modify it with a calendar but i did not modify it yet however its already giving me the hard time. Kindly advise, any kind of help will be appreciated
Thanks

Hi,
With the information provided I cannot for sure get to the error but here is what I would check.
Firstly, I was wondering if the 5th parameter in the @Prompt can be Primary_Key. I thought it would be either free or constrained.
Secondly, please the LOV values for the @ prompt are being populated from 'Calendar Day\LovDay IntervalBase'. So I would check the date format being used there.
Third, the To and From dates are alphaneumeric and not dates, so I am not sure how the comparision would happen.
Hope this helps.

Bpel parsing issue with special characters...

Hi All,
We are integrating Oracle Sales Order information with OTM as Order Releases.
For this we are sending the Sales Order in the form of clob from the procedure to the Bpel process.
1. A PL/SQL procedure would send the Sales order XML as a CLOB.
2.In the BPEL process , we are performing ora:parseXML() function on the clob obtained.
3.A patch was installed on the BPEL SOA server:
10.1.3.3.1 MLR#8, Patch#6906880 which was supposed to handle all the parsing activities at run time.
4. But when ever any special character viz..; #,UNIT¿S etc the BPEL process is failing with a fault string due to Parsing error.
5. Could you please provide us a workaround for solving this issue ASAP with all the special characters.
I have provided a sample xml tag due to which the parsing is failing in the bpel process. here it is failing because it is not able to parse : UNITÂ¿S successfully...

is there some other bpel patch or some other workaround using which whatever input value comes in , the bpel is able
to successully parse that through..
we are stuck with this special character parsing issue as of now and go live is very near ...your help/inputs would be highly appreciated

Guys,
I am new to OTM and SOA/BPEL architecture.
Could you please suggest me in detail as how to integrate OTM with outside world using BPEL.

Oracle Text query: Escaping characters and specifying progression sequences

How can I combine the escaping of a search string and the specification of progression sequences within an oracle text query
so that in all cases the correct results are delivered (see example below)?
The scenario in which to use this is the following:
+ Database: Oracle Database 10g Enterprise Edition Release 10.2.0.2.0
+ Requirement: Hitlist of results ordered by score whereby the different part within
the result list are specified using progression sequences within oracle text query
Example:
create table service_provider (
id number,
name_c varchar(100),
uri_c varchar(255)
insert into service_provider values (1,'ABB Company Mgmt','http://www.abb-company-mgmt.de');

insert into service_provider values (3,'SABBATA United','http://www.sabbata-united.de');
insert into service_provider values (4,'ABB','http://www.abb.de');
insert into service_provider values (5,'AND Company Mgmt','http://www.and-company-mgmt.de');
insert into service_provider values (6,'Dr. Andas Ming','http://www.dr-andas-ming.de');

Query Performance Issues

Hi Gurus,
I m woking on performance tuning at the moment and wants some tips
regarding the Query performance tuning,if anyone can helpme in that
rfrence.
the thing is that i have got an idea about the system and now the
issues r with DB space, Abap Dumps, problem in free space in table
space, no number range buffering,cubes r using too many aggrigates,
large IC,Large ODS, and many others.
So my questionis that is anyone can tell me that how to resolve the
issues with the Large master data tables,and large ODS,and one more
importnat issue is KPI´s exceding there refrence valuses so any idea
how to deal with them.
waiting for the valuable responces.
thanks In advance

Hi Amit
For Query performance issue u can go for :-
Aggregates : They will help u a lot to make ur query faster becuase query doesnt hits ur cube it hits the aggregates which has very less number of records in comp to ur cube
secondly i wud suggest u is use CKF in place of formulaes if any in the query
other thing is avoid upto the extent possible the use fo nav attr . if u want to use them use it upto the minimal level reason i am saying so is during the query exec whn ever there is nav attr it provides unncessary join to ur MD and thus dec query perfo
be specifc to rows and columns if u r not sure of a kf or a char then better put it in a free char.
use filters if possible
if u follow these m sure ur query perfo will inc
Assign points if applicable
Thanks

Oracle text query

Hi,
I have a View object with various attributes (eg, name1, name2, name3, address1, address2, address3 etc). A query/table component based on this view object works just fine. However, I wish to replace name1, name2, name3 and other attributes in the query with just 'name'. These attributes are still to be shown in the result table. This new 'name' attribute will be used in an Oracle Text query clause, instead of individual searches on each attribute.
My plan was to simply make the various name1, name2 etc attributes non-'queryable' in the View def to hide them from the query. Then I'd add a transient 'name' attribute. My hope was, that I could override the getWhereClause() in the ViewObjectImpl and simply tack on the oracle text clause to the WHERE (example below):
WHERE CONTAINS (
SOMECOLUMN,
            '<query>
   <textquery lang="ENGLISH" grammar="CONTEXT">TRANSIENT_ATTR_VALUE
..... Oracle Text query grammar stuff here .... </query>') > 0How do I access the transient value in the ViewObjectImpl to add the above SQL? Or am I going about this in completely the wrong way?
thanks,
Barry.

Based on what I found in

136.     Introducing a Checkbox to Toggle a Custom SQL Predicate on an LOV's Search Form. [11.1.1.0.0] 19-NOV-2008
I have the following implementation, which seems to work. Does anyone see any problems with this?
With regard to SQL injection, does ViewCriteriaItem sanitise the 'val' from the query, or should I do that manually here myself?
    @Override
    public java.lang.String getCriteriaItemClause(ViewCriteriaItem vci) {
        if ("OraTextTransientAttrib".equals(vci.getAttributeDef().getName())) {
            if (vci.getViewCriteria().isCriteriaForQuery()) {
                String val = (String)vci.getValue();
                logger.debug("Doing oracle text name search on '" + val + "'");
                // simplified version of my oracle text query
                return "CONTAINS ('<query>..... " + val + "....</query>') > 0 ";
            } else {
                // SQL predicate for no changes to the results
                // spaces needed if you have several of these blocks
                return " 1=1 ";
        // other blocks for other similar oracle text attribs
        return super.getCriteriaItemClause(vci);
    }

Declare a text query

If I have a text query in visual studio EXEC DCC_SPP_GetPeopleByDepartment @Department
how can i declare the @Department to be varchar (8000) ?
I tried declaring it in the stored procedure, but when I deploy the report, the query fails as it's looking at the text query.

Try :
EXEC DCC_SPP_GetPeopleByDepartment Convert(varchar(8000),
@Department)
