• Where clause in the "default_where" of get_block_property is not cancelled...

  Hello

  I developed a form with two blocks.

  The first - block of non - database contains the criteria.

  Database of the other - block-displays the records according to the inserted.

  Also, there is a button that executes the query criteria.

  The code of the BUTTON WHEN PRESSED is as follows:

  declare

  v_where varchar2 (3000);

  Start

  v_where: = null;

  go_block ('EKKREMOTHTES_AIT_TSG');

  clear_block (no_validate);

  v_where: = get_block_property ('EKKREMOTHTES_AIT_TSG', default_where);

  If: blk_criteria.site_id is not null then

  v_where: = v_where |' and site_id = "'|: blk_criteria.site_id | ''';

  end if;

  If: blk_criteria.yphr_klimakio is not null then

  v_where: = v_where |' and yphr_klimakio = "'|: blk_criteria.yphr_klimakio | ''';

  end if;

  If: blk_criteria.send_date_from is not null and: blk_criteria.send_date_to is not null then

  v_where: = v_where |' and send_date between to_date('''|| to_char(:blk_criteria.send_date_from,'dd/mm/yyyy')||''',''dd/mm/yyyy'') and

  to_date('''|| to_char(:blk_criteria.send_date_to,'dd/mm/yyyy') | " (', "dd/mm/yyyy)";

  end if;

  If: blk_criteria.eq_group1 is not null then

  v_where: = v_where |' and eq_group1 = "' | : blk_criteria.eq_group1 | " ' ;

  end if;

  If: blk_criteria.eq_type1 is not null then

  v_where: = v_where |' and eq_type1 = "' | : blk_criteria.eq_type1 | " ' ;

  end if;

  If: blk_criteria.eq_group2 is not null then

  v_where: = v_where |' and eq_group2 = "' | : blk_criteria.eq_group2 | " ' ;

  end if;

  If: blk_criteria.eq_type2 is not null then

  v_where: = v_where |' and eq_type2 = "' | : blk_criteria.eq_type2 | " ' ;

  end if;

  blk_def_where ('EKKREMOTHTES_AIT_TSG', v_where);                                    / * a form routine that makes the set_block_property(<block>,default_where) * /.

  do_key ('execute_query');

  end;

  The above code works when the user inserts the criteria for the first time. Later when the user deletes certain criteria - clear criteria in the block of criteria-

  and he pushed the button of the query results are exactly the same...

  After have debugged the problem, clause v_where is not nullied (do not get the value zero) in order to get the new criteria.

  Can you identify the error?

  Note: I use Oracle Forms 10 g Db 11 g v.2

  Thank you very much

  SIM

  SIM,

  The procedure "blk_def_where" sets the block where clause by using the DEFAULT_WHERE or the ONETIME_WHERE constanct?  Gets it to the user that the same results as the DEFAULT_WHERE sets the property WHERE permanently so the second time through, the 'v_where' is NOT null.  Check your BLK_DEF_WHERE procedure and if it does not use the ONETIME_WHERE constanct, change isn't.  The alternative would be to put DEFAULT_WHERE = NULL after the call to the built-in EXECUTE_QUERY.

• Oracle Forms - "DEFAULT_WHERE" is lost when used an apostrophe

  Hi all

  I faced a problem with Oracle Forms for a long time and I have no idea of what is happening so far.

  I have a block based on a stored table. I used the following statement to set the WHERE clause for this block:

  set_block_property ('MTI', default_where, l_where);

  Variable l_where has the following form:

  l_where: = ' WHERE art_nr IN (')

  || "SELECT the md5 ma_nww_ww_dat art_nr."

  || 'WHERE trunc (sysdate) BETWEEN md5.gueltig_ab AND md5.gueltig_bis'

  || ' AND UPPER (md5.art_bez_altern) AS "' | : gi_intern.txt_match_name | '%''';

  The problem arises when the user tries to search for an article, using the MATCH_NAME an apostrophe (for example, GRANT). In this case, the where conditions are lost and all records are returned as a result.

  Could you help me understand what the problem is?

  Thank you very much!

  I think you should put the link reference inside the clause, instead of its value.

  I mean: If you set the where_clause ' like mycol. "' | : my_item |' % "'

  you to hard-code the value of: my_item at the time of the set_block_property.

  I could do this instead (simplifying):

  l_where: = ' upper (md5.art_bez_altern) like: gi_intern.txt_match_name | » %'' ';

  Thus, the: my_item value will be assessed at the moment execute_query, and I think that forms will address the apostrophe in the variable to better link if hardcode you just what you do in your example.

  It is, forms will treat it in the same way it would if you were query mode enter and entering a filter: with variable binding.

  In fact, I think that this kind of filter you can even enter at the time of the design (with single apostrophes)

  In addition, liaison is supposed to be better for the performance of subsequent queries.

• SET_BLOCK_PROPERTY DEFAULT_WHERE property

  Hi all

  I use the oralce forms builder 10g version.

  I want to get the display records according to the criteria of research as

  Assume that DESCRIPTION field "NATURE %" when I click the search the block button to display the record whose DESCRIPTION starts with "NATURE CATS," NATURE DOGS etc...

  I used

  SET_BLOCK_PROPERTY ('BLOCK_NAME ', DEFAULT_WHERE,' where as DESCRIPTION: QF_VALUE');

  It gives me error DESCRIPTION is not a valid identifier.

  Because BLOCK NAME DESCRIPTION article DATABASE NON-base.

  I have description data in another table, where I can join the 2 tables.

  Please let me how can know I get the required data.

  Thank you.

  Set the block based on the code description code

  I guess, you have a description code in your BLOCK_NAME building that is based on your description table, then try as follows

  SET_BLOCK_PROPERTY ('BLOCK_NAME', DEFAULT_WHERE, ' description_code IN (SELECT description_code ' |) ")

  'OF description_table' |

  "Description WHERE AS % | : QF_VALUE | » %');

  Sorry for my English
  Thank you to

  Andreas is correct - your where clause has a problem at the end.

  We will build cleaner where clause:

  DECLARE
  
  WH_CL VARCHAR2(3000);
  
  AND_TXT VARCHAR2(5);
  
  --
  
  PROCEDURE CHECK_PART(COL_NAME VARCHAR2) IS
  
  BEGIN
  
  IF NAME-IN('BLKKEY.'||COL_NAME) IS NOT NULL THEN
  
  WH_CL := WH_CL || AND_TXT
  
  || COL_NAME ||'= :BLKKEY.' || COL_NAME;
  
  AND_TXT := ' AND ';
  
  END IF;
  
  END CHECK_PART;
  
  --
  
  BEGIN
  
  CHECK_PART('CODE');
  
  CHECK_PART('BAR_CODE');
  
  CHECK_PART('CAT_NO');
  
  CHECK_PART('SUB_CAT_NO');
  
  CHECK_PART('SUPPLIER_NO');
  
  SET_BLOCK_PROPERTY ('TBL_WHS_ITEMS', default_where, WH_CL);
  
  EXECUTE_QUERY;
  
  END;

  If you ask how to make sure at least one of your BLKKEY items is not null, you can add this before the SET_BLOCK_PROPERTY:

  IF WH_CL IS NULL THEN
  
  MESSAGE(' PLEASE ENTER AT LEAST ONE FIELD');
  
  RAISE FORM_TRIGGER_FAILURE;
  
  END IF;

  .. .and why people use tabs like this in their code?

• Problem in the use of Default_where 'between '.

  I want to find the appmnt_date between the from_date and to_date

  Hi Guy,
  Change to:

  In short, the problem is BETWEEN (: BL_CONTROL_BLOCK.) FROM_DATE AND: BL_CONTROL_BLOCK. To_date), after, BETWEEN, there is no need of pair of hooks for the beach.

  I hope this helps.

• default_where clause

  Hello
  
  I have a requirement where if the user types in a part of the string, it must question him recordings using as and %.

  If the user types in "Jo" as name, records for which the string Jo must be returned.
  
  I have my QUERY before trigger like this.

  select emp_id,first_name,last_name from employees 
       where (firstname LIKE '%Jo%') and (firstname = :1);

  I do not understand where and why (firstname =: 1) comes. The query returns all rows.
  
  Thank you

  Hello

  I guess firstname is your DB field and then when you enter enter_query mode and type something in this area and where clause, then it takes as an argument for this field (firstname) Db and puts it in where clause.

  Ideal thing to do would be to create an element of database field not and ask the user to enter the name in this field and then question.

  something like that
  declare r_string varchar2 (100);
  Start
  r_String: = NAME_IN('DHIRAJ.) ITEM11'); item11 here is an article from the database for dhiraj datablock
  If r_String is not null
  THEN
  Set_Block_Property ('YES', default_WHERE, ('name AS' | ")) ' ||' %' || r_string | » %'||''''||''));

• Block based on the stored procedure cannot modify Default_where clause

  Hi all

  I tried to create a block based on the stored procedure that it works very well with the result set for the refcursor. But if I need to add filters on the block using where clause in the palette of goods or

  using the property block set in where clause, it does not error but does not review filters .

  tried everything to you please let me know. This is a restriction whereby we can set filters on the block when we create the block based on the stored procedure.

  Thank you

  Check in Form Builder Help:

  Creating a block of data from a procedure that uses a ref cursor

  ... You can't pass a WHERE or ORDER BY clause clause in a stored procedure.

  But you can send your WHERE condition using the query Source Arguments.

  If the procedure is on the side of the database (not in the forms module), ensure that the procedure is not vulnerable to injection of SQL code.

• How to execute the query

  I want to execute a specific request, but I have no idea about this please someone help me how to a specific query, run?

  Try this.

  Yes you can write this in next item key of you text element.

  Go_Block ('Your_Block_Name');

  Set_Block_Property ('Your_Block_Name', DEFAULT_WHERE, 'STUDENT_ID =' |: STUDENT_ID);

  Execute_Query (No_Validate);

• help with the form builder

  Fit, I have the edit button and its function is that when I press the button change go IDs (text_item) and run the query

  but my problem is that when I enter text_item in any id it displays just first record

  for example

  When I enter id... 1 data display

  but I enter the id 2, 3, 4... its just id 1 information display

  Use of pre_query trigger.

  For example

  You write the code below in your button.

  Go_Block ('Your_Block_Name');

  Execute_Query (No_Validate);

  After that, you write the query pre relaxing on your query block.

  Set_Block_Property ('Your_Block_Name ', Default_Where,' Id =' |: MYSEARCHBLOCK.) Item_Id);

• Hi everyone how can filter query on the form

  I a request form based on a database of datablock table and I use some items based on the datablock control to run the query, the user can use a portion of this Articles to filter the query, what is the best way to implement this form I have tried using the set_block_property default _where but is not working If the user is using all of the elements to filter the query, which is better use of the cursor or the default_where and how.

  Hello

  You can try to use the LIKE operator instead of =.

  Str_Condition: = ' AS "' |:. . '%'' AND LIKE ''' || :. || '%'''; etc.

  And use it as the DEFAULT_WHERE clause.

• The block, by removing the block, by asking questions of compensation block

  Hello

  The current design of the shape is as below (without changes to the formatting and design)

  (1) has a P - database no block parent heading

  (2) has a child block C - block of data with a single table T

  In essence, the data is stored in a single table

  How to achieve the following

  (1) clear the block (both P and C) If you erase the block P

  (2) by deleting the records to both P and C, if the deletion of the record in P

  (3) by deleting records in C

  (4) ask Parent P (F11 and F11 control) reviews and pulling on the files in C (Ctrl + F11)

  Concerning

  S

  Hello

  Pls use for their feature the following...

  1. you can use WHEN - BUTTON - PRESSED to erase the two Trigger block using Clear_form;

  2 & 3 - oracle database to create relationship master-detail between tables using foreign keys and cascading deletes using the FOREIGN KEY constraint with the ON DELETE CASCADE clause. Oracle/PLSQL: delete foreign keys with cascade

  However, Oracle Forms manage thing delete cascade internally when you define the relationship properties. I recommend the creation of another table master P with the relationship specified in table C.

  U GOLD create a relationship out of shape between the two blocs.

  If not, try to use-DELETE or KEY of VALIDATION Trigger at the level of the form, FOR INSTANCE:

  Note: do not to consider deleting the master, since non-base of data block DELETE is used ONLY in db transaction deleting.

  So you can set their NULL values as

  :P_block.dept_id :=NULL;

  or you can use CLEAR_ITEM;

  CLEAR_ITEM('P_block.dept_id');

  Syntax

  REMOVE the TABLE Table_Name

  WHERE search_condition;

  Example of

  IF: P_block.dept_id is NOT NULL, THEN

  DELETE T

  WHERE t.dept_id =: p_block.dept_id;

  4-to resolve this point

  PLS, set the property default_where of the data block C for example

  dept_id =: p_block.dept_id;

  Therefore, to create a TIME-NEWS-BLOCK-INSTANCE Trigger on C block diagram

  Write the following text

  GO_BLOCK('C');

  EXECUTE_QUERY;

  Amatu Allah.
