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.

Hi
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.

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.

Hi 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:

      ELSE

--now below is the code of the index:

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.

Problem creating Oracle text index

Hi,
I am trying to create an index in Oracle 9i using Oracle Text.
First i gave this grant as SYSDBA:
"GRANT ALL ON CTX_DDL TO <USERNAME>"
Then i executed the following :
EXECUTE CTX_DDL.CREATE_SECTION_GROUP('MYPATHGROUP','PATH_SECTION_GROUP');
CREATE INDEX SDS_SLIDE_XML_IDX ON SDS_SLIDE_DATA (SLIDE_XML)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('SECTION GROUP MYPATHGROUP');
but I got the following error :
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: Oracle Text error:
DRG-50857: oracle error in dricon.get_primary_key

Any ideas?

Oracle Text will not index the content inside the portlet of the pages. The portlet is treated as a portlet instance item and only the relevant attributes are searched for, like display name of the portlet, etc.

I have problem with The text size during the last weeks.

My IPad 2 is a little weird. During the last weeks it seems it works ok, and suddenly text size, icons size grow very big and it takes me ages to get my IPad back to its original size. Is this happening to anyone?

Short of something that might be going on with the settings, have you tried a reset of the iPad?
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the button.
In the event that something wonky is going on with your settings you can try Settings>General>Reset>Reset all settings. No data will be lost but all settings will have to be entered again.

Problems with keywords being attached during import that I did not designate

Hello all -
I am using Lightroom 2.2 on a Windows machine. I was futzing around before watching the videos and somehow now when I import photos, I have a bunch of keywords attached to each one that I had no intention of attaching. Be be clearer - when I am importing - the keyword box is either blank, or I put other keywords in it - NOT the ones that keep showing up. But each time - the keywords I didn't want show up with the ones I did want. I created a custom keyword set by mistake in the beginning, but I went back and erased those keywords, just in case it was auto-adding them. Doesn't make a difference. I'm wondering if I should go back to factory presets for everything, but I'm not sure if that would help, or how to do it.This is really keeping me from importing photos - because if I have several hundred photos, I have to then select them all to delete the keywords, then select them and put in the correct ones....a pain! What am I doing wrong? Many thanks - I've looked everywhere for this answer and it keeps eluding me.. Julie

Never mind! (I think) - it turns out that I had a metadata preset to include those keywords - I have since cleared that box and now none of those offending keywords show up

Problem with blob column index created using Oracle Text.

Hi,
I'm running Oracle Database 10g 10.2.0.1.0 standard edition one, on windows server 2003 R2 x64.
I have a table with a blob column which contains pdf document.
Then, I create an index using the following script so that I can do fulltext search using Oracle Text.
CREATE INDEX DMCS.T_DMCS_FILE_DF_FILE_IDX ON DMCS.T_DMCS_FILE
(DF_FILE)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('DATASTORE CTXSYS.DEFAULT_DATASTORE');
However, the index is not searchable and I check the following tables created by database for my index and found them to be empty as well !!
DR$T_DMCS_FILE_DF_FILE_IDX$I
DR$T_DMCS_FILE_DF_FILE_IDX$K
DR$T_DMCS_FILE_DF_FILE_IDX$N
DR$T_DMCS_FILE_DF_FILE_IDX$R
I wonder what's wrong with it.
My user has been granted the ctx_app role and I have other tables that store plain text which I use Oracle Text are fine. I even output the blob column and save as pdf file and they are fine.
However the database seems like not indexing my blob column although the index can be created without error.
Please advise.
Really appreciate anyone who can help.
Thank you.

The situation is I have already loaded a few pdf document into the table's blob column.
After I create the Oracle text index on this blob column, I find the system generated index tables listed in my earlier posting are empty, except for the 4th table.
Normally we'll see words inside the table where those are the words indexed by oracle text on my document.
As a result, no matter how i search for the index using select statement with contains operator, it will not give me any result.
I feel weird why the blob is not indexed. The content of the blob are actually valid because I tested this by export the content back to pdf and I can still view and search within the pdf.

Jap.

Help with creating oracle text index on 2 columns with partial html data

Hi,
I need to create an oracle text index on 2 columns.
TITLE - varchar(255) = contains plain text data
DESCRIPTION - CLOB = contains partial HTML data
This is what I created.
begin
ctx_ddl.create_preference ('Title_Description_Pref', 'MULTI_COLUMN_DATASTORE');
ctx_ddl.set_attribute('Title_Description_Pref', 'columns', 'TITLE, DESCRIPTION');
end;
begin
ctx_ddl.create_preference ('bid_lexer', 'BASIC_LEXER');
ctx_ddl.set_attribute('bid_lexer', 'index_stems', 'ENGLISH');
ctx_ddl.create_section_group('htmgroup', 'HTML_SECTION_GROUP');
end;
create index Bid_Title_Index on Bid(title) indextype is ctxsys.context parameters ('LEXER bid_lexer sync (every "sysdate+(1/24)")');
create index Bid_Title_Desc_Index on Bid(description) indextype is ctxsys.context parameters ('LEXER bid_lexer DATASTORE Title_Description_Pref sync (every "sysdate+(1/24)") filter ctxsys.null_filter section group htmgroup');
The problem is when I do a CONTAINS(description, '$(auction)')>0. I get results where the descriptions have the "auction" word (which is correct). But, the results also returned rows where the search word is inside an IMG tag. e.g. <img src="http://auction.de/120483" alt="Auction Logo"/>.
What I would like is to exclude rows where the search word is inside HTML tag attributes, results expected are rows having <a>Auction</a> or <p>For Auction</p> ... etc. Basically stripping the html tags and leave the text contents.
I'd appreciate some input.
Thanks,
Amiel

Oracle Text indexation problem

Hello all,
we recently migrate one of our database from oracle 10.2.0.2 to an Oracle 10.2.0.4, and since then, Oracle Text indexer engine is unable to work properly.
Indexing datas systematically result in the following error :
DRG-50857: oracle error in dreii0fsh
ORA-06550: line 1, column 106:
PLS-00302: component 'S_MODE' must be declared
ORA-06550: line 1, column 10:
PL/SQL: Statement ignored
Note that datas that were indexed with the previous version of Oracle can still be found with "Select... where contains...", though new datas can't be indexed at all.
Can anybody help me with this issue ?
Edited by: methos on 11 mai 2010 06:59

See on metalink:
'DRG-50857: oracle error in dreii0fsh' when creating TEXT index [ID 750898.1]
It seems you upgraded the binaries,but not Oracle Text itself.

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.

Oracle Text index hangs(Oracle 11g linux enterprise edition)

Hi guru,
One very criticial and showstopper issue coming in Oracle Text Indexing.
I have table ResourceTable(ResId,Contents blob ,docformat)
I am creating text index on Contents column by using follwing command:
create index [IndexName] on [TableName] (contents) indextype is ctxsys.context ('lexer mylex stoplist ctxsys.default_stoplist format column ISDOCFORMAT sync(every "sysdate+1/24") storage my_text_storage memory 200M')parallel 2
I found there is one document of text/html type which hangs oracle text indexing thread.Oracle doest not give any error message keep using CPU 100% and no progress.
I then create test table with same stucture and put this corrupted documet record in this table.and did indexing again but its not doing index /not ignoring it and hangs .We have also tried to use timeout feature of inso filter so that if such type of document comes at the time of indexing oracle text indexing process will bypass it after specific time interval but still same issue comes and oracle is not bypassing such faulty document.
This is realy show stopper issue and any kind of help will be greatly appricited.

You need to raise an SR with Oracle Support for this, and send them the file which is causing the hang. It should then be easy to investigate the problem and schedule a fix.
If you don't have a support contract, you could send the file to me and I'll raise a bug. However, if we fix it you won't be able to get the fix until it appears in the next downloadable version.

Oracle text indexes

Can anybody know is it possible to create two oracle text indexes on one column, for example, CTXCAT index and CTXRULE index and what will be during the querying of that column? is it a good practise?
Thanks in advance.

When in doubt, test and see. Yes, you can create two different types of Oracle Text indexes on the same column. If you create a CTXCAT index and a CTXRULE index, then queries using CATSEARCH will use the CTXCAT index and queries using MATCHES will use the CTXRULE index. When querying with CATSEARCH, it will find all rows where the terms searched for are found within the column value. When querying with CTXRULE, it does the opposite, and finds all rows where the column values are found within the terms searched for. Please see the demonstration below. As to whether it is a good practice, it depends on what you need. If you need both types of searches, then yes. If not, then no, it would be unnecessary overhead.

About index memory parameter for Oracle text indexes

Hi Experts,
I am on Oracle 11.2.0.3 on Linux and have implemented Oracle Text. I am not an expert in this subject and need help about one issue. I created Oracle Text indexes with default setting. However in an oracle white paper I read that the default setting may not be right. Here is the excerpt from the white paper by Roger Ford:
URL:http://www.oracle.com/technetwork/database/enterprise-edition/index-maintenance-089308.html
"(Part of this white paper below....)
Index Memory                                  As mentioned above, cached $I entries are flushed to disk each time the indexing memory is exhausted. The default index memory at installation is a mere 12MB, which is very low. Users can specify up to 50MB at index creation time, but this is still pretty low.
This would be done by a CREATE INDEX statement something like:
CREATE INDEX myindex ON mytable(mycol) INDEXTYPE IS ctxsys.context PARAMETERS ('index memory 50M');
Allow index memory settings above 50MB, the CTXSYS user must first increase the value of the MAX_INDEX_MEMORY parameter, like this:
begin ctx_adm.set_parameter('max_index_memory', '500M'); end;
The setting for index memory should never be so high as to cause paging, as this will have a serious effect on indexing speed. On smaller dedicated systems, it is sometimes advantageous to temporarily decrease the amount of memory consumed by the Oracle SGA (for example by decreasing DB_CACHE_SIZE and/or SHARED_POOL_SIZE) during the index creation process. Once the index has been created, the SGA size can be increased again to improve query performance."
(End here from the white paper excerpt)
My question is:
1) To apply this procedure (ctx_adm.set_parameter) required me to login as CTXSYS user. Is that right? or can it be avoided and be done from the application schema? This user CTXSYS is locked by default and I had to unlock it. Is that ok to do in production?
2) What is the value that I should use for the max_index_memory should it be 500 mb - my SGA is 2 GB in Dev/ QA and 3GB in production. Also in the index creation what is the value I should set for index memory parameter - I had left that at default but how should I change now? Should it be 50MB as shown in example above?
3) The white paper also refer to rebuilding an index at some interval like once in a month:   ALTER INDEX DR$index_name$X REBUILD ONLINE;
--Is this correct advice? i would like to ask the experts once before doing that. We are on Oracle 11g and the white paper was written in 2003.
Basically while I read the paper, I am still not very clear on several aspects and need help to understand this.
Thanks,
OrauserN

Perhaps it's time I updated that paper
1. To change max_index_memory you must be a DBA user OR ctxsys. As you say, the ctxsys account is locked by default. It's usually easiest to log in as a DBA and run something like
exec ctxsys.ctx_adm.set_parameter('MAX_INDEX_MEMORY', '10G')
2. Index memory is allocated from PGA memory, not SGA memory. So the size of SGA is not relevant. If you use too high a setting your index build may fail with an error saying you have exceeded PGA_AGGREGATE_LIMIT. Of course, you can increase that parameter if necessary. Also be aware that when indexing in parallel, each parallel process will allocated up to the index memory setting.
What should it be set to? It's really a "safety" setting to prevent users grabbing too much machine memory when creating indexes. If you don't have ad-hoc users, then just set it as high as you need. In 10.1 it was limited to just under 500M, in 10.2 you can set it to any value.
The actual amount of memory used is not governed by this parameter, but by the MEMORY setting in the parameters clause of the CREATE INDEX statement. eg:
create index fooindex on foo(bar) indextype is ctxsys.context parameters ('memory 1G')
What's a good number to use for memory? Somewhere in the region of 100M to 200M is usually good.
3. No - that's out of date. To optimize your index use CTX_DDL.OPTIMIZE_INDEX. You can do that in FULL mode daily or weekly, and REBUILD mode perhaps once a month.

Problem with Oracle 11g(32 bit) installation on windows 7 ultimate edition

Hello all,
I have a problem with Oracle 11g(32 bit) installation on windows 7 ultimate edition (32 bit).
I have successfully installed it immediately after OS installation. But today, i have decided to deinstall it and go for Oracle 10g version for 32 bit.
Everything went normal during installation, but i can see the services is not present in services.msc. Also its throwing some exception for dbca, netca
Now i tried to deinstall it and again go for 11g. But even the same story here..
Can anybody give me a solution for this..
-Regards
Rajesh Menon

ur problem is that u install latest version and now u trying to installing old version.
now u need to uninstall 10g and delete oracle from services, if the probleme presist then u should
install fresh windows 7.

SaqibNo need to install a fresh OS. That's like tearing your house down just because you wired a lamp wrong and blew a circuit breaker.
There are MeaLink notes on how to eradicate an Oracle install from Windows, but it boils down to this:
Stop all Oracle services
In the registery:
- Delete all oracle services from the register (HKLM\SYSTEM\CurrentControlSet
- Delete the entire Oralce folder from HKLM\Software
reboot
Delete the ORACLE_HOME directory and any other Oracle related directories/files. Offhand, it seems like there is an Oracle directory under Program Files.
reboot

A lot of problems with Oracle BI SEE 11g

I have a lot of problems with Oracle BI SEE 11g
1. I upgraded my BI SEE 10 repository and can it openning in offline mode.
2. I can't deploy my upgraded repository in EM MW Control 11g - when i try to open Farm_bifoundation_domain->Business Intelligence->coreapplication, i get error "Stream closed
For more information, please see the server's error log for an entry beggining with: Server Exception during PPR, #41".
Opening Logs by EM control doesn't work too.
in file middleware\user_projects\domains\bifoundation_domain\servers\AdminServer\logs\AdminServer.log i see this event:
<Error> <HTTP> <oratest.itera.ru> <AdminServer> <[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <b639ac3e56e9a463:bd6fa7f:12ac7271e09:-8000-00000000000009e8> <1283408423378> <BEA-101019> <[ServletContext@329875093[app:em module:/em path:/em spec-version:2.5]] Servlet failed with IOException

Have you any ideas?
3. Ok, i taking sample repository and adding a new datasource in it:
Database: Oracle 8i
Connection pool:
Call interface OCI 8i/9i
Data source name:
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (Host = oraapp) (Port = 1521) ) ) (CONNECT_DATA = (SID = MYSID) ) )
This settings are working fine in BI 10.
In BI 11g i get this funny error: "The connection has failed". I lost my time in attempts to connect to Oracle DB 8, but have not results. After that i hacked button "Query DBMS" at "Features" tab, pressed it and when get error "ORA-03134: Connections to this server version are no longer supported.".
Therefore Oracle 8 DB as datasource not supported. Am i right?
4. In sample repository i added oracle DB 10 as datasource, then added two dual tables and their connection to all layers.
Now i open BI Answers, and trying to create report with one dummy column, Now i have this error:
Error
View Display Error
Odbc driver returned an error (SQLExecDirectW).

Database features are defaults.
Does anyone solve this problem?

Turribeach, Thanks for you time.
1. It was not a question
3. Yes, i have read platforms, but not supported datasources. Now i see, that BI 11g support as datasource Oracle DB 9.2.0.7 or higher. I am sorry.
4. I'm using OCI connection type
Now i recreate Database in Physical schema and answers is showing report data for me! But only from one table, when i use columns from to tables from one datasource, i geting error:

Please Help: A Problem With Oracle-Provided 'Working' Example

A Problem With Oracle-Provided 'Working' Example Using htp.formcheckbox
I followed the simple steps in the Oracle-provided example:
Doc ID: Note:116534.1
Subject: How to use checkbox in webdb for bulk update using webdb report
However, when I select a checkbox and click on the Update button, I get a "ORA-01036: illegal variable name/number" error. Please advise. This was a very promising feature.
Fred
Below are step-by-step instructions provided by Oracle to create this "working" example:
How to use a checkbox in WEBDB 2.2 report for bulk update.
PURPOSE
This article shows how checkbox can used placed on WEBDB report
and how to use it.
SCOPE & APPLICATION
The following example to guide through the steps to create a working
example of this.
In this example, the checkbox is used to select the records. On clicking
the update button, the pl/sql procedure is called which will update col1 to
the string 'OK'.
After the update is done, the PL/SQL procedure calls the report again.
Since the report only select records where col1 is null, the updated
records will not be displayed when the report is called again.
Step 1 - Create Table
From Sqlplus, log in as scott/tiger and execute the following:
drop table chkbox_example;
create table chkbox_example
(id varchar2(10) not null,
comments varchar2(20),
col1 varchar2(10));
Step 2 - Insert Test Data
From Sqlplus, still logged in as scott/tiger , execute the following:
declare
l_i number;
begin
for l_i in 1..50 loop
insert into chkbox_example values (l_i, 'Comments ' || l_i , NULL);
end loop;
commit;
end;
Step 3 -Create SQL Query based WEBDB report
Logon to a WEBDB site which has access to the database the above tables are created.
Create a SQL based Report.
Name the report :RPT_CHKBOX
The select statement for the report is :
select c.id, c.comments, c.col1,
htf.formcheckbox('p_qty',c.id) Tick
from SCOTT.chkbox_example c
where c.col1 is null
In Advanced PL/SQL, (REPORT, Before displaying the form), put the following code
htp.formOpen('scott.chkbox_process');
htp.formsubmit('p_request','Update');
htp.br;
htp.br;
Step 4 - Create a stored procedure in the database
Log on to the database as scott/tiger and execute the following to create the
procedure.
Note: Replace WEBDB to the appropriate webdb user for your installation.
In my database, I had installed webdb using WEBDB username, hence user webdb owns
the packages.
create or replace procedure chkbox_process
( p_request in varchar2 default null,
p_qty in wwv_utl_api_types.vc_arr ,
p_arg_names in wwv_utl_api_types.vc_arr ,
p_arg_values in wwv_utl_api_types.vc_arr
is
i number;
begin
for i in 1..p_qty.count loop
if p_qty(i) is not null then
begin
update chkbox_example
set col1 = 'OK'
where chkbox_example.id = p_qty(i);
end;
end if;
end loop;
commit;
/* To Call Report again after updating */
SCOTT.RPT_CHKBOX.show
(p_request=>'Run Report',
p_arg_names=>webdb.wwv_standard_util.string_to_table2(' '),
p_arg_values=>webdb.wwv_standard_util.string_to_table2(' '));
end;
Summary
There are essentially 2 main modules, The WEBDB report and the pl/sql procedure (chkbox_process)
A button is created via the advanced pl/sql coding which shows on top of the report. (The
button cannot be placed at the bottom of the report due to the way WEBDB creates the procedure
internally)
When any button is clicked on the report, it calls the pl/sql procedure chkbox_process.
The procedure is called , WEBDB always passes the parameters p_request,p_arg_names and o_arg_values.
p_qty is another parameter that we are passing additionally, This comes from the checkbox created
using the htf.formcheckbox in the report select statement.
The pl/sql procedure calls the report again after processing. This is done to
show how to call the report.
Restrictions:
-The Next and Prev buttons on the report will not work.
So it is important that the report can fit in 1 page only.
(This may mean that you will not select(not ticked) 'Paginate' under
'Display Option' in the WEBDB report. If you do this,
then in Step 4, remove p_arg_names and p_arg_values as input parameters
to the chkbox_process)

If your not so sure you can use the instanceof
insurance,
Object o = evt.getSource();
if (o instanceof Button) {
Button source = (Button) o;
I haven't thoroughly read the thread, but I use something like this:if (evt.getSource() == someObjRef) {
// do that voodoo
]I haven't looked into why you'd be creating a new reference...
