Enter_query for non-database block

Hi there,
I have a non-database block. When I click on enter query button from toolbar, i get"this function cannot be performed here' error. I want to bring up records based on certain math calculations. I was planning to write a pre-query trigger and add those to pre-query trigger. Will it work since it is a non-database block? Or should i create a button on form to get records populated?
Thanks

You won't be able to use the Query-Process-triggers PRE-QUERY and POST-QUERY on a non-database-block.
But... If you want to "simulate" the behaviour of querying, you can use the KEY-EXEQRY-trigger and put your logic there. This should also work with the standard forms-menus. To supress the error-message on entering query-mode you should additionally write as KEY-ENTQRY-trigger with code NULL;

  • Problem in Execute query on non-database block and database block together

    Hi All,
    In my form,i have
    1. First block is Non-database block with one non-database item.
    2. Second and third blocks are database blocks.
    Now the problem is that i want to perform execute-query for all the blocks.
    If the cursor is on the non-database item of 1st block and i clicks on the "Enter-query" then i am getting message " This function can not be performed here".
    If i click on the item of the database block and then clicks on the "Enter-query" and then "execute-query" it's working fine.
    But i don't want to do in this way.
    My cursor will be on the First block only and then it should perform execute-query.
    I am using this non-database item to copy value of this item to the item of the database block item.
    I think i make you understand about my problem.
    I am using forms 10g on Window xp.
    Please help me.

    Hi!
    Simply create a enter-query trigger on the non-database-block:
    begin
    go_block ( 'database_block' );
    enter_query;
    end;If your search criteria is in the non-database-item in the first block,
    you actually do not need the enter_query build-in.
    Just create a execute-query trigger on the first block like:
    begin
    go_block ( 'database_block' );
    execute_query;
    go_item ( :System.trigger_item );
    end;And in a pre-query trigger on the database-block copy the
    value of your seach item into the item you want to search for.

  • HOW TO CREATE MULTIPLE RECORDS IN A NONE DATABASE BLOCK?

    I have a Form where I have a none database block with unbound items. The block
    has 10 records. In the when-new-block instance I run a query by which I would
    like to fill up the block with data. The code fragment looks like the
    following:
    begin
    declare
    tmp_curr_rec_id number;
    begin
    -- a hibak kiolvasasa
    for c_hibak in ( select h.*, h.rowid
    from hibak h
    where 1=1 -- WF - Ide kerul a szurofeltetel
    order by bejelentes_datum asc
    ) loop
    -- bemasoljuk az adatokat az unbound item-ekbe
    :mc_adat.ub_azonosito := c_hibak.azonosito;
    :mc_adat.ub_verzio_letrehozas_datum :=
    c_hibak.verzio_letrehozas_datum;
    :mc_adat.ub_bejelento := c_hibak.bejelento;
    :mc_adat.ub_bejelentes_datum := c_hibak.bejelentes_datum;
    :mc_adat.ub_wf_verzio_csomopont :=
    c_hibak.wf_verzio_csomopont;
    :mc_adat.ub_wf_utolso_esemeny_szoveg :=
    c_hibak.wf_utolso_esemeny_szoveg;
    :mc_adat.ub_hiba_leiras := c_hibak.hiba_leiras;
    :mc_adat.ub_hiba_hely := c_hibak.hiba_hely;
    :mc_adat.ub_rekord_jelleg := 'H';
    :mc_adat.ub_rowid := c_hibak.rowid;
    -- beallitjuk a rekordot-ot olyanra, mintha semmi nem valtozott
    volna
    -- nem szeretnenk a form bezaraskor mindenfele figyelmezteteseket
    -- olvasni a kepernyon
    tmp_curr_rec_id := get_block_property( :system.current_block,
    current_record );
    set_record_property( tmp_curr_rec_id, :system.current_block,
    status, new_status );
    create_record;
    end loop;
    end;
    end;
    The block's update allowed, insert allowed, delete allowed property is set to
    true.
    The result of the code above is that only the last record fetched shows up in
    the block. The problem is - as I found out - is that aech record is fetched,
    the values are copied to the block items, but the create_record built-in
    command would not move the cursor to the next row.
    Can some one please help me with this?
    TIA,
    Tamas Szecsy

    The problem was with the following code segment:
    tmp_curr_rec_id := get_block_property( :system.current_block, current_record );
    set_record_property( tmp_curr_rec_id, :system.current_block, status, new_status );
    After omitting these two lines, the code worked properly.
    Thansk for all whoe replied.

  • Ordering a non-database block....

    Hi ,
    Is it possible to order and how a non-database block according to user's willing...????
    Thanks , a lot
    Simon

    That will work in sql*plus but to use it in a program you'll need to parameterise the Order By clause. That's why I wrote mine the way I did. It will work in sql*plus if you enter 'A' and 'B' (including the quotes) and it will work in a program if you replace the placeholders with variables.

  • Execute query with non database block

    How to execute query with non database block when new form instance trigger.

    Hi Kame,
    Execute_Query not work with non database block. To do this Make a cursor and then assign values to non database block's items programmatically, see following example,
    DECLARE
    BEGIN
         FOR i IN (SELECT col1, col2 FROM Table) LOOP
                :block.item1 := i.col1;
                :block.item2 := i.col2;
                NEXT_RECORD;
         END LOOP;
    END;
    Please mark if it help you or correct

  • Forms - query into non database Block

    This is the data in the table. I am querying into a non database block.Have two lines of data
    1. 1062|Sanitation and Cleaning|N|1025
    2. 1063|Eyewash|N|1025
    go_block('qc_procedures');
    first_record;
    loop
    Open C3;
    Fetch C3 into :qc_procedures.procedure_id,
    :qc_procedures.procedure_desc,
    :qc_procedures.optional,
    :qc_procedures.procedure_type_id;
    Exit when :system.last_record = 'TRUE';
    next_record;
    Close C3;
    End loop;
    I am only able to get the first line of data

    I'm not quite sure if i understand your problem.
    First, you didn't post the definition of your cursor C3.
    Second, if you want to populate the block using the cursor, you should loop over the cursor and not over the block, something like
    Open C3;
    first_record;
    loop
      Fetch C3 into :qc_procedures.procedure_id,
      :qc_procedures.procedure_desc,
      :qc_procedures.optional,
      :qc_procedures.procedure_type_id;
      Exit when C3%NOTFOUND;
      next_record;
    Close C3;Third, it would be much easier to base your block on a table or on your query (using FROM-clause-query), then there would be no need for any code.

  • ADF : Non Database Block Fields Validation

    How should I add validation to "Non Database Block Fields"?
    My question is based on this example:
    see http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html
    "24. Passing User-Entered Data in "Non Database Block Fields" to Stored Procedure/Function"
    http://otn.oracle.com/products/jdev/tips/muench/stprocnondbblock/PassUserEnteredValuesToStoredProc.zip
    Should I add the validation to an Entity Object (where no fields are 'linked' to database fields) on which I base the "NonDBBlock" View Object?
    If this is "Entity Object abuse" (because no database involved, only validation), what would be a better approach?
    many thanks
    Jan Vervecken

    hi Steve
    If all the attributes in my Entity Object are marked as not persistent, it makes sense this Entity Object doesn't "take part" in a transaction.
    I would like to avoid the message box about Commit or Rollback when closing my Frame, because this use case isn't transaction related in any way.
    It seems to work if I override the getPostState() method like this:
    public byte getPostState()
         return EntityImpl.STATUS_UNMODIFIED;
    question :
    Are there any side effects to this approach or is there another way to mark an Entity Object as "not in any transaction"?
    thanks

  • RM-30410: Warning: Single Record property ignored for non-control block

    Hi gurus,
    I have one block, as oracle default behavious is that when any user enters record and during that if he/she hits down arrow key then it gets to next new record, i want to prevent this behaviour.
    In other words i want that user should not enter second record and if he or she needs to enter second record after saving first then user can only do if he navigate to the form second time.
    In property pallete i put yes to single record but when i compile the form it gives me following warning
    FRM-30410: Warning: Single Record property ignored for non-control block Employees
    Created form file C:\my_forms\employees.fmxPlease seeks help that how can i sort it out.
    Thank you
    Hina

    if he/she hits down arrow key then it gets to next new record, i want to prevent this behaviour. Change the block's key-down and/or key-nxtrec trigger to
    begin
      null;
    end;(or give the user a message "Key not allowed here").

  • Query a database block based on a non-database block

    hi everybody
    can anybody help me as how to query a database block based on a non-database block, without a master-detail relationship?
    i have a block : date_input which contains a non-database item: start_date
    another database block (event_block)containing details of an event
    i have to input a date in the start_date and query the event_block
    in wich trigger should i insert the code?
    thanks

    If you are trying to query your database block (event_block) using the value from start_date in your non-database block, then you can set the Where clause in the database block using:
    SET_BLOCK_PROPERTY ('event_block', DEFAULT_WHERE, 'your where clause that includes start_date');
    Place this statement in a trigger that is executed prior to the block being queried.

  • Date query in non database block

    Hi Experts
    I am doing query in a database via a non data base block.The field in which i want to query is join(DD-MON-YYYY hh24:MI:SS) and my non database block is join.
    I want that i shall give the date in the join field like DD-MON-YYYY format and the related datafrom the database will come out.
    So In the KEY-EXEQRY i have written
    IF :system.mode = 'ENTER-QUERY' THEN
    IF :EMP.JOIN_DATE is not null then
    TRUNC(:EMP.JOIN_DATE):=to_date(:EMP.JOIN,'DD-MON-YYYY');
    END IF;
    END IF;
    EXECUTE_QUERY;
    It is showing compilation error.
    The construct is not allowed as the origin of an assignment
    Can you please tell me what is wrong with it.
    detail of join is -
    data type -char
    Regards
    Rajat

    To restrict a query to something based on a non-database-block you need a different approach:
    1. Do nothing in the KEX-EXEQRY-trigger
    2. Create a PRE-QUERY-trigger with the following logic:
    IF :CTRL.JOIN_DATE is not null then
      SET_BLOCK_PROPERTY('EMP', ONETIME_WHERE, 'TRUNC(JOIN_DATE)=TRUNC(:CTRL.JOIN_DATE)');
    END IF;I assumed the following:
    - CTRL is the name of your non-database-block and EMP is your database-block
    - There is an item JOIN_DATE of datatype DATE in your CTRL-block
    - There is a database-column named JOIN_DATE in yourt EMP-table.
    - You are using Forms 10g, if not use DEFAULT_WHERE instead of ONETIME_WHERE
    If one of these is not TRUE, adjust the code i provided to match your object-names.

  • Non database block

    i have a non data base datablock to view the date and the use(i ssign them at the when new form instance trigger),but the problem that if i make clear all for the form the date and the user will be cleared,so i write the code at when new block instence trigger for the first navigetable data block it works but i think that it is no effient any suggestion???

    All our forms have both a control block with basic data (form-name, lookup keys), and a standard clear-all procedure, Whenever user presses the key-clrfrm key, or whenever we re-display all blocks on the form, we first call the U01_Clear_Screen procedure.
    U01_Clear_SCreen saves all values in the fields we don't want cleared on the control block into pl/sql variables, then does a:      CLEAR_FORM(NO_VALIDATE,FULL_ROLLBACK);It then replaces the saved values into the control-block items.
    The Clear_Screen procedure is common to every form, and includes more code if necessary if there are other things that need to be saved/replaced when the screen is cleared.

  • How to create Entity object for Non Database Object.

    Friends,
    I have a requirement something like, I will be getting some huge amount of data from external system via CORBA, I have to display the data in jsff page in <af:table>. My requirement is If User updates any of the row I need to identify what are all the rows user updated and Need to invoke again a CORBA call for only UPDATED Rows.
    Basically here, I am not dealing anything with the Database, I assume using Entity we can find out a status of the row whether the row is updated/deleted/created .
    How can I create an Entity object in this case.
    Any help will be highly appreciated !!!

  • IAS for non Database based web site

    We are using IAS for our website using Oracle Forms/Reports and Oracle databse 8i.
    We have now to develop small websites in pure HTML (no java, no Oracle Forms), we are wondering if it is still a good option to use IAS as the web server for those applications. If yes, do we simply have to define a new application in IAS but without connection string to a database?
    Same questions for web site based on Oracle 8i databse and JSP (without any Oracle forms and reports)

    Hi,
    Yes, you can do that by creating a new custom folder that will contain the following sql:
    select 'W' Flag_lov from dual
    union all
    select 'F' Flag from dual
    union all
    select 'M' Flag from dual
    union all
    select 'D' Flag from dual
    Then cerate an item class on that field and associate it with the "Flag" field from the original folder you use in the report.
    In the process of the item class creation you can select the items that will use that item class ("Flag").
    Now when you'll run the workbook you'll get the LOV for the flag.
    Also after you finished the configuration i suggest that you'll hide the custom folder you just created since it has no use for the users. you can do that by going to the folder properties and change the "Visible to User" to "Yes".

Maybe you are looking for
