• Clear the cache or return the Web query

  I have a situation where the user selects a combobox control, based on what they choose, it sends and receives data through a web service and fills another drop-down list box.  There is also a clear button that clears all selections of previous drop-down list, the list box washing box drop-down fist with the original list of choices.  If the user will choose the same selection on the first drop-down list box, as above, it does not send it through the service web like system (flex) already think he did.  Is there a way to clear the cache or force the web service to return?

• PL/SQL Query return function, adding the column links

  Hi all
  
  I'm working on a SQL report with the area type = function from PL/SQL Query to return
  All columns are generated dynamically based on my mapping table and a column of ID.
  So whenever the page is loaded, according to the ID mapping table returns a set of columns in a particular order.
  So not only the columns are dynamic, but the order of the columns varies also.
  But the first 1 column is standard (it doesn't come from the mapping table) and is coded in my pl/sql block hard.
  
  I'm fighting with the addition of a link to this column. The link must be a Javascript function which takes the parameters in the form of 2 columns in the mapping table.
  My pl/sql block is something like that...

  v_select := 'SELECT <g href=javascript:f_report1(#map_id#,#comments#)><img src=""></a> as report1, ';  // g=a
  v_cols := 'contains all columns from the mapping table based on a ID(hidden item)';
  v_from := 'FROM table';
  v_where := 'where condition is put in here';
  v_query := v_select||v_from||v_where;
  return v_query;

  Now, I'm not able to transmit the values of this #map_id # and #comments # correctly. I tried so many different combinations of channels, but could not make it work.
  
  I'm not sure that the order of this map_id and commentscolumn and therefore cannot connect through the report attributes.
  How can I go to a column value to the function?
  
  
  
  Thank you
  Dippy

  This should work if all goes well:

  v_select := q'[ SELECT '' as chart, ]';

• How to get the query of the region "PL/SQL function body returns the query string"?

  Hello
  
  is it possible to get the query string from the region of type "PL/SQL function body returns the query string"?
  
  I can get the definition of the region as a PL/SQL procedure, but I am interested in the returned query. I tried to write something like
  
  < pre > v_return_query: = «...» » ;
  : P49_QUERY: = v_return_query;
  Return v_return_query; < / pre >
  
  to save the return on hidden item P49_QUERY string, but it does not work. I get the error message: ERR-1002 cannot find the item for the "P49_QUERY" element ID in the application '4000 '.
  
  Kind regards

  If you need to make reference to a page element in the block then you can use this type of control to avoid having to use generic column names:

  if apex_application.get_current_flow_sgid(:APP_ID) = apex_application.get_sgid then-- runtime  :P9_SQL := vSQL;else-- design time  null;end if;
  

  But if all you want to do is capture the SQL debugging you can take all the references element in the block and use the insert statement (in a debug table) as I showed earlier.

• How can I show all the results returned by a sql query?

  Hi guys,.
  
  I need your help.
  Let's say I have a table: TableA. Fields in TableA are aleg, anon, monkeys. The following sentence can return, in general, several rows: select anon from TableA where aleg = somevalue. I would like to show the result of the anon column but no luck. If I try to display the results in a TextArea and the origin is a sql query shows that the first value of the line. I tried to see the like: display text (based in PLSQL) and a block anonymous plsql and coding
  DECLARE
  v_anon TableA.anon%TYPE;
  CURSOR v_cur IS
  Select anon from TableA where aleg = somevalue;
  BEGIN
  OPEN v_cur.
  LOOP
  SEEK v_cur INTO v_anon;
  EXIT WHEN v_cur % NOTFOUND;
  : FIELD_IN_FORM: = v_anon;
  END LOOP;
  CLOSE V_cur;
  END;
  but in this case, he showed no results.
  So the first question is what type of field can I use to show the result. And the second is what can I do to be able to show all the results returned by the query (if more than one line).

• Assigning a page element in the region of the "body of function return PLSQL SQL query.

  I've not been here in a long time. I like the new forum text editor!
  
  I have a search page in my application that contains a return region of query SQL PLSQL function body. I use PLSQL to build a query based on the user entries in various page numbers (search text, serial number, year, etc.). Using PLSQL is very useful to enforce the page quickly because there are 1/2 million lines with a lot of text fields some of which are CLOB.
  
  Users want to know how many rows were returned, but if I allow using a paging system that includes the total performance dies because ApEx has to sort through all the pages of output. Instead, I use ' line varies X to Y "without the part of" Z", and it's pretty fast. I can't use the #TOTAL_ROWS # because it does not work with this system of pagination.
  
  So, I built a code within the region of function body PLSQL to build a second query that counts only the lines based on the input parameters. I can do this query within the region using EXECUTE IMMEDIATE and the number to an output variable. The disconnect is that I can not then assign it to a page element. If I add a statement assigned to a page element, either by
  
  : P45_COUNT: = p_count;
  or
  APEX_UTIL. SET_SESSION_STATE ('P45_COUNT', p_count);
  
  then when I submit the changes I get
  
  ERR-1002 unable to find point item ID 'P45_COUNT' in the application '4000 '.
  
  as if the ApEx is not looking for the item in my application, but in the application development environment. I am able to write the results to a table and then recover data in the next region. That's how I got around the problem, but it seems too complicated and unnecessary.
  
  I wrote the following code just to illustrate the problem.
  
  Make sense? Any ideas?
  
  Thank you!

  Bilal, thanks for the nice problem! Another possibility to double check is to write a small PL/SQL function that returns 1 if a duplicate id is found, then equate to 0: "NUMBER of RETURN of Duplicate_Token_Found (p_str_main in VARCHAR2, p_str_trial VARCHAR2). It should analyze the second string and could use p_str_main LIKE '%', | l_id | ', %' for each id. In any case, the query complete (without that) is given below:

  I found the need to deduplicate regular expression:

  AND RegExp_Instr (r_c.itm_path | r_i.path, ',(\d+),.*?,\1,') = 0)

• Œuvres SQL query to MS SQL Server 2008, but not when you use the database kit

  I have this SQL query:

  DECLARE TABLE (@DataTypeTable)
  Name varchar (128).
  TypeID INT)

  -Add comma delimeted type data in the temporary table names
  INSERT INTO @DataTypeTable (name)
  SELECT * from WhatWeShouldDoRead.func_Split (@DataTypeTrimmed, ',')

  SELECT the name OF @DataTypeTable

  That takes a comma delimited by the string and returns the string as a table.  It works correctly in Microsoft SQL Server Management Studio.  When I run this as a stored procedure I return nothing.  There are no errors, SQL or otherwise.  I checked that I am connected to the correct database and the stored procedure is responsible without changing any error chain which is reported of this stored procedure (that code is not shown in the example above).  Has anyone seen this problem before, or have experience with SQL/Labview interfaces to tell me what I am doing wrong?

  Thanks in advance.

  
  

• Classic report shows wrong "could not parse the SQL query: ORA-00942" error after migrating app to the new environment

  After migrating my APEX 4.1 application to a new environment, one classic report displays a "cannot parse the SQL query: ORA-00942: table or view does not exist" error when the page is displayed. Change the region to report SQL source to somehow (e.g., remove spaces, changing the order of the variables in the WHERE clause) immediately solves the problem, but by returning to the source of the region causes the report error again (the source region valid code without error, however).

  Throw the error message:

  Select v.id,

  v.Col1

  of view_vw v

  where (: P1_FILTER is null or)

  v.col2 = :P1_FILTER)

  Do not throw error:

  Select v.id,

  v.Col1

  of view_vw v

  where (:P1_FILTER is null or)

  v.col2 = :P1_FILTER)

  Changing the order of column in the report has the same effect; i.e. He arranges, but return back to the original column order causes the error to display.

  It's as if a cached result for the correct select statement used by the report is displayed. However, the application does not use the caching of page/region. Any ideas of what could be the cause?

  He solved. Ultimately, all that was necessary was to clear the DB cache using:

  alter system flush shared_pool;
