Direct Database mapping with Grid

hi everyone,
we are making an which ask user to make changes in
databse table directly, this will led several altring in database
scheema. so we need to run alter query at every instance.
can we directly map any of grid like JTable or
something with database so that when every any user made change in
table it automaticaly reflects to database.
regards
vidhi.

1) You need to use DefaultTableModel
2) You may need to use ResultSetMetaData, DatabaseMetaData
3) You need to implement javax.swing.event.TableModelListener
in tableChanged method you can perform database related operations.

  • Direct Database Request with Dashboard Prompt LOV Source

    I have complex Direct Database Request query having Dashboard Prompt. In Dashboard prompt I want to have LOV. But to create the DPrompt having LOV, I must have the table/column in Subject Area. How I can have table in RPD not connected or joined with any table in RPD?
    The idea is to do the reporting based on direct query with Prompt/LOV but do not want to include the prompt source table with other my main logical model which is used for other purpose.

    Hi Kishore
    Thanks for the reply but it is little less clear because I already have working Dashboard level prompt where
    1. Instead of LOV I type the value, use the Presentation Variable as Set Variable on Dashboard Prompt, say pDepartment
    2. Created direct database rqeuest query having where condition .. WHERE Department= '@{pDepartment}'
    And the above Dashboard works great. Only problem is that I want to have LOV for Department for which I need to have the respective table/column in RPD

  • Direct DB request with go url

    Hi Gurus,
    I have a parent report and a child report.
    The child report is a Direct database request with no reference to any tables in the RPD.
    Now I want to use go url to pass the values to the direct database request. Is this feasible?
    Thanks,

  • EclipseLink Direct Map with Joining mapping issue

    Hi EclipseLink Team,
    We encountered an issue to map an attribute as Direct Map with Join Fetch enabled in EclipseLink Workbench 1.1.1 (Build v20090430-r4097).
    Basically, we have the following data model:
    SESSION
    SESS_NO (PK),
    PARAM_SESS
    SESS_NO (FK) (PK),
    PARAM_NAME (PK),
    PARAM_VALUE
    Then we have Session.java persistent entity associated with SESSION table. This class contains Map attribute sessionParameters which we map as Direct Map with PARAM_SESS.PARAM_NAME as key and PARAM_SESS.PARAM_VALUE as value (referenced by PARAM_SESS.SESS_NO = SESSION.SESS_NO).
    The described mapping works fine without Joining enabled (both for Lazy and Eager Loading).
    But we have cases when we want to get parameters for a number of sessions. And disabling of Joining leads to a number of performed SELECT SQL queries (both for Lazy and Eager Loading) those are bad for performance.
    So we have chosen the Eager Loading and set the Join Fetch option to Outer. Then we have got the following:
    I see in the log the only SQL query performed: SELECT DISTINCT t0.SESS_NO, …, t1.PARAM_VALUE, t1.PARAM_NAME FROM {oj SESSION t0 LEFT OUTER JOIN PARAM_SESS t1 ON (t1.SESS_NO = t0.SESS_NO)}. This is pretty good for us. This query returns exactly what we expect when executing on the database. But the Map attribute for every session is populated incorrectly: Maps are empty (not corresponding to available relational data).
    Could you please let us know if this is a bug, or kind of known issue or we made something wrong? Some hints and proposals would be very helpful and appreciated.
    I should mention that for now we want to map all of this for read only purpose.
    Thanks.
    Best Regards,
    Alexey Elisawetski

    James,
    I've tried both 1.2 release and 2.0 (v20091121-r5847) but received the same result - empty Map.
    Moreover, for both versions the following string was absent in deployed XML file:
    +<direct-key-field table="PARAM_SESS" name="PARAM_NAME" xsi:type="column"/>+
    Therefore, on application initialization I have got an exception: org.eclipse.persistence.exceptions.DescriptorException with message This descriptor contains a mapping with a DirectMapMapping and no key field set.
    So I was forced to add the line manually.
    This seems buggy to me...
    Regards,
    Alexey

  • Why does 10g EM with GRID install a 9.0.1.5 database (windows 2003)

    Having a hectic day with EM/DG. I reinstalled my enterprise manager with grid control 10g and opted to let it create a new database. I then looked at the version and found out it created a 9.0.1.5.1 database. Whats up with this??

    If that's EM Grid 10.1, Probably because the version of AS that EM builds on, builds on that version (of DB) :-) EM's repository is, of course, still 10.1.0.x
    In the correct circumstances, EM 10.1 supports having its repository in Database 10.1.0.x where x=3 or higher.

  • Direct Database Request - EBS

    Hi All,
    I am new to OBIEE but have a question regarding Direct Database Request. We have our EBS data stored in the OBIEE Data Warehouse but we'd also like to be able to use some of our Oracle SQL Developer queries against our EBS database directly using OBIEE as the platform.
    Is there any issue with having our EBS data in the data warehouse as well as a data source for Direct Database Requests? I read something about security concerns involving write-access. I figure it's easier to use our SQL queries that we have already created than to attempt to map all of the tables and fields into the data warehouse. Also, some of the queries would be nice to have in real-time.
    Thx,
    Mike

    I don't have to worry about the transactional EBS data getting tangled in the data within the warehouse right? Also, are there any security concerns?I dont think so.
    I typically use an Appsro (read-only) user when querying EBS data. Will I have the option of using read-only or will I have write access? I ask b/c I read something about this that warned of security risk of overwriting data.Read only is fine, since BI is to see data, unless you implement Write-back functionality there wont be any write(data updates) in db.

  • Issue in Color Theme on the map with ADF geographic components

    I am facing an issue in bringing up a map using color theme .I can able to bring up a map with color themes using geographic components feature in ADF.
    The problem here is 'Edit Color Map Theme' dialog which lists Map Theme in five categories like continents,counties,countries,states_abbrev,states_names.
    we had implemented map using Color Theme based on the states_abbrev and found it was working properly.
    But after some days we found that the settings we made to work for the map no longer works and resulted in no color theme on the map being displayed on the page.
    It was found that the states_names works properly instead of states_abbrev by that time.
    But again after some days it didnt work with state_names and we revert back our code to follow state_abbrev so as to get the desired result.
    Does somebody know where is the problem and how to approach this issue?

    Quick Install is gone.
    Database repair doesn't work.
    Color coded categories is gone, and as you've discovered Theme colors are gone.
    Print to Excel is gone.
    Many desktop clients that worked with 4.2 do not work.
    It won't work with legacy devces.
    and others.... There are lots of complaints about 6.2 scattered around the forums.  Personally, the HotSync manager keeps forgetting the connections I've set, and goes to default views.
    You aren't missing much of anything, IMHO.

  • Database selection with Invalid Cursor error in RSDRI_INFOPROV_READ

    Hi Everyone.
    I am using RSDRI_INFOPROV_READ Function module for reading data from a multiprovider.
    Logic of the code is as following
    while <more data>
    CALL RSDRI_INFOPROV_READ reading data in E_T_DATA
    Append lines of E_T_DATA to EO_T_DATA.
    If total lines of data in EO_T_DATA > 200000
    <save EO_T_DATA in a file using GUI_DOWNLOAD>
    <clear EO_T_DATA>
    EndIF
    EndWhile.
    As soon as number of record exceed 200000 first file is saved, but after that next data call results in error.
    Error says "Database selection with invalid cursor".
    I suspect that this because of call to FM GUI_DOWNLOAD. While calling this FM after RSDRI_INFOPROV_READ causes system to commit and again the cursor is tried to open in next call casuing it to fail.
    But it is imperative for me to save data in file at regular intervals as data volume is huge.
    Any pointers in this direction will be helpful.

  • Direct database request and session variable value

    Hi,
    I have a problem by doing the following : idea is to have report with a list of all tables in user schema (which are not all in repository physical layer).
    By clicking on the name of any, should bring answer report which is done as direct database request doing basically select * from table_clicked (this will be basically the same table with sufix _err holding error rows).
    What I'm trying to do is having some kind report for error rows which can be in different tables in my database. So i had in mind to construct name of table i need , and pass it to database request through session variable. Am i doing right by doing direct database request like this :
    select * from 'VALUEOF(NQ_SESSION.TestVar2)'
    Is there another easyer way of doing this? I know this can be done by gourl by passing parameters but not sure how when i can't filter columns in direct database request (this can be different tables with different names of columns). I hope i didn't complicated this too much.
    Thnx in adwance

    Hi,
    I know this is a hack, and would be much more easy to create one table with dimension and measures, but this is intended to be used with code generator, which can produce different error tables with different column names in different time: It is not conviniet for somebody to add them to repository every 5 minutes. For example : i run my workflow and for first run I have errors in table1(let us say customer table with 30 columns) and if click on the table name in some answer report, i want to see all the bad records in the table. Tomorrow after the run, there are bad records in table1 and in table2 (lets say products) so I would have choice to pick table 1 or table2 and see al the bad records in any of these tables. This means that I can not now which tables will I have tomorrow, and as it is generic, I can manually add some tables in my model, and would have to add err table also as a possibility to have error rows?
    I saw post saying that you can pass parameter value by using go url functionality, by modifying configinstance file, but didn't suceed - http://gerardnico.com/wiki/dat/obiee/logical_sql/obiee_session_variable_go_url . Maybe some mistake or any better solution? I created session variable TestVar2, also modified instanceconfig.xml by adding this before </ServerInstance>
    <ParamList>
    <Param name="NQ_SESSION.TestVar2" source="url" nameInSource="SETVAR"/>
    </ParamList>
    and used go url in column formula : ''||"Physical Targets"."Physical Table"||''
    Can I use @1 for using first column value?

  • How can I use an Express database build with RAA in Express Objects???

    Hello, everybody!
    I have installed Express Server and Client on my computer. I've build an Express database With Relational Access Manager mapping data from an Oracle database.
    Now I want to use this express database in Oracle Express Objects.
    I understand that an express database build with understand can be used by defining a connection to Express Server and using the option Relational Access Manager Connection.
    But, I didn't understand the settings of this option. I open the settings window and there it is :
    - the MASTER DATABASE Box where I have to write the name of the CUBE from the express database build with understand?
    - the RDC File Box : what do I have to write here? I've read the HELP but I didn't understood. There is no file with the RDC extension in my computer.
    Thank you for your help!

    you can extend it, very easly, with an Airport Express.
    once you connect the AExpress, on the App Airport Utility, in Wireless tab choose to "Extent a Network", you will be able to select your Network enter your Network Password and it is done
    i have 2 AExpress to extend my signal and also to Airplay to Remote Speakers and works perfectly

  • Date format in Direct database request

    I have a report with direct database request.
    I have a date prompt..I am storing the date in a Presentation Variable named pv_date.
    In the direct database request, I have a where clause:
    WHERE business_date IN ( @{pv_date}{'1/1/2013'} )
    when I run open dashboard for the first time, its throwing me an error near TIMESTAMP.
    WHERE business_date IN( TIMESTAMP ''2013-01-01 00:00:00'')
    AND ALSO When I run this report from dashboard after choosing a date say 2/20/2013, I see the query as:
    WHERE business_date IN (2013-02-20 00:00:00)
    and hence throwing error.
    Its throwing error in both the cases. How do I change the format in WHERE clause..
    Ideally, I want the query to be WHERE business_date IN ('2/20/2013') or Business_date IN ('2013-02-20')

    Thank you both.
    I am using Sybase and hence used convert function.
    But still I see the word TIMESTAMP in the query which is causing issue.
    business_date IN(CONVERT(char(10), TIMESTAMP ''2013-03-27 00:00:00'',101))
    and when I run the report by choosing any date, I see this: business_date IN(CONVERT(char(10),2013-03-27 00:00:00,101)) ; throwing error because No single quoted for the date.
    How do I remove the word TIMESTAMP?? and how do I impose single quotes..

  • Filter on the reports created using DIRECT DATABASE ACCESS in obiee 10g

    How do i filter on the report that is created by using DIRECT DATABASE ACCESS in obiee 10g?
    I have reprot A with link to report B, report B is created using DIRECT DATABASE ACCESS. so it is just a table, but i need to filter out 2 columns.
    here is the query in REPORT B:
    select strm, acad_group, crse_id, class_section, count(emplid) from v_crse_enrl
    group by crse_id, strm, class_section, acad_group;
    the link in REPORT A:

    from this link to report B.
    thank you!!

    I didnt tested using url, but the same works with using presentation variables.
    To your direct sql add where clause for those two columns like WHERE col='@{col1}' and col ='@{col2}'
    and try to run from url.
    let me know updates

    My intention of performing FOD schema installation was to follow the tutorial "Database Development with JDeveloper" at http://st-curriculum.oracle.com/obe/jdev/obe11jdev/ps1/databasedevelopment/obe_%20databasedevmt.htm. But I stopped at the last topic "Creating and Debugging PL/SQL Objects in the Database" ->"Running a SQL Script to Create an Object Type" when trying to create a object using script on the page.

    Any response will be appreciated.

    1. you dont have to insall Oracle database at the BO machine side, you just need any database to hold the BO repository.
    2. you cant connect directly using BO, only Crystal reports can connect directly to R3 database, you need to have a BW in between.
    extract your data into the BW, and let BO connect to BW using the BO integration kit for SAP solutions.
    3. no you dont have to have 3 different machines, using one BO machine you connect to them all, but you may need build a  BO environment, (Development, Production servers)
    good luck
