• Best place to initialize the View object query where clause or params

  Where is the best place to initialize the View object 'where' clause before the page is initially rendered? Or how should it be done?
  Specifically, I can't set these values in the entity or view objects because I need information from the user or information Session
  the user has entered before you navigate to the page. I want to prepare the View object so that the results of the query appears something reasonable
  the first time before using chooses search.
  
  Note: The view object must exist and I need to access managed beans to define the query.
  
  Is there an event hook (java code) that can be called before the page is rendered?
  Also, there are hooks that can be called when the user navigates to another tab or page?

• Query where clause of different table without data

  Hello
  
  Oracle 11g.
  
  I have a 'Points' table that stores information point.
  In carts, users can record information on these points.
  Then, the user can some carts he wants to apply to display data in a report.
  
  Here is a minimal example (I hope I didn't too many mistakes):
  

  create table points (
       pt_id integer,
       pt_type varchar2(1),
       pt_accl varchar2(15),
       pt_class varchar2(10),

  );
  
  create table carts(

  insert into user_selected_classes values (1, 1, 'AAKCM');
  
  insert into user_selected_status values (1, 3, 'A');

  If a user may for example have the following carts (according to the example above):
  

  cart_1
  Types : 'B', 'S'
  Accls : 'BIONH1'
  Classes : 'AAKCM'
  Status : [All]
  
  cart_2
  Types : [All]
  Accls : 'CTF1', 'CTF2'
  Classes : [All]
  Status : [All]
  
  cart_3
  Types : 'T'
  Accls : 'L4C'
  Classes : [All]
  Status : 'A'

  When no value is selected for an item, it must return all values.
  
  For now, I have the following query:
  

  with t as (select cart_id d from carts where cart_current = 'Y')
  select
       *
  from
       points
  where
       ...
       and (
            pt_type in (select ust_type from user_selected_types where ust_cart_id in (select d from T))
            or not exists (select 1 from user_selected_types where ust_cart_id in (select d from T)))
       and (
            nvl(pt_accl, '' - (null)'') in (select nvl(usa_accl, '' - (null)'') from user_selected_accls where usa_cart_id in (select d from T))
            or not exists (select 1 from user_selected_accls where usa_cart_id in (select d from T)))
       and (
            pt_class in (select usc_class from user_selected_classes where usc_cart_id in (select d from t))
            or not exists (select 1 from user_selected_classes where usc_cart_id in (select d from T)))
       and (
            pt_status in (select uss_status from user_selected_status where uss_cart_id in (select d from T))
            or not exists (select 1 from user_selected_status where uss_cart_id in (select d from T)))

  It works, but the data or mixed...
  If the user apply cart_2 and cart_3, I don't want to for example points to accl "L4C" with status "E", forthcoming.
  I just want to return the union all selected each carts.
  
  Of course I can loop over Cart ID, PL_SQL, and build the query dynamically, as:
  

  for cur_c in (select cart_id d from carts where cart_current = 'Y') loop
       l_query := l_query || 'select ... from ... where ...' || ' union all ';
  end loop;
  l_query := substr(l_query,1,length(l_query)-11);

  But imagine the user ask 500 wagons..., I've reached the limit of varchar2.
  I can't use a CLOB that I use Oracle APEX to view the report, and he expects the query a varchar2.
  
  I don't want to use a temporary table, as it is too slow for the application (I've tested).
  
  You have a solution?
  
  Thank you.

  The cross join creates all the possible combinations of carriage/point. Then they are checked for 4 columns according to your rules. I think that the result is correct, if I read your question right?

  If it's the most effective depends a lot on your actual data. Are the usual cases each cart sets a very small subset of points, or each cart will usually define a substantial part of the points. Carts of how are your tables? How many tables of user_selected_? How is the distribution? How many points? Indexes are available?

  If the data are such that it can "pay" to build all of the possible production and "weed" down, then the foregoing can be very effective. If the data is such that the result is usually very small subset then the effectiveness may depend on the index are available.

  Test and see if it works for you ;-)
  If it takes hours, so if please give some information on the quantity and distribution of the data and the expected quantity and size carts etc. Then we could think in a different way...

• selection of values to query where clause

  Hi guys, it of maybe a silly question but do not know if I approach the solution in the correct engineering.
  
  At the top of my form, I framed that the user fills out the different values. These values are then used to refine the query results in the block below. I know that I can go in the datablock being interrogated and set the where the clause equal to the value of the text boxes above, but I don't feel it is the right place to do it.
  
  If I do like this when the above text box is empty, it returns no results when infact I want to ask all if the values are left white. So should I put it in motion pre? If so how should we do?
  
  Any help would be greatly appreciated.
  
  Thank you.

  In the trigger of the QUERY before block you, just put the value in the corresponding element

    :block.name := :ctrl.selection ;

  My goal is to create a report of sales data for 116 stores containing daily sales and count of comments in recent years. My challenge is that I am pulling data from the same table, but with different dates to get data from last year and the week in data from date of last year.
  
  
  The dates used for reports are:
  
  SalesDate = 06/04/2009
  SalesDateForLastYear = 2008-06-05
  SalesDateBeginningOfWeek = 01/06/2009

  Question: Since they all use the same store of nbrs, I specify on each request? Can't I just specify only once on outer query Where clause?
  
  Also, how would fit the following of HOEK script:
  See how I put 1 field based on another field value
  
  He reads a record for each store of 116 stores in the database. There are 2 situations that have been addressed by Hoeks code:
  For each of the 116 stores in the store table, there must be 1 and only
  registration of 1 stock to match the record of MyStoreTotals. However, sometimes there is no record of inventory.
  and sometimes there will be 2 (in a case where a manager of database updates)
  After daily treatment) files. If so, the record with Is_posted = 1
  is the one that should be included in the query. The following text accomplishes this:
  -chr (39) is the single quote
  

   Select StoreId, 
           DollarVariance 
    from   (select store.storeid, 
                     case
                            when inv.storeid is null then 'None'
                            when inv.is_posted = 0 then 'NP'
                            else chr(39)||inv.total_dol_var||chr(39)
                      end as DollarVariance, 
                      row_number() over (partition by store.storeid order by inv.is_posted desc) rn  
                 from  myInven inv 
                 right outer join mystores  store
                                on store.storeid = inv.fk_str_main_id
                                and inv.busi_date = to_date(SalesDate, 'dd-mon-yyyy'))
        where rn = 1;      

  Can I put this request on the place where clause of the outer to query I put on a JOIN clause?

  So I guess that's why you used the MAX.

  That is right.
  I used CASES to identify and complete the necessary columns since the first set of results (WITH).
  So then I more or less "swivels somehow" lines of this result set to the columns, each store will appear once the most.

• Passing the value of the where clause with the page

  Dear friends,

  I have a requirement like when I select a selection list value I should pass this value to sql query where clause without submitting the page

  ex I have a select like: P1_Dept guess I selects the value 10 in this

  then I have a query select * from emp where deptno =: P1_Dept.

  DB. ORACLE 11G

  APEX 4.1.1.00.23

  is this possible? can someone help me please in this topic

  Thanks and greetings

  Vballeda

  Suppose we have the selection list with the name P1_DEPT and query for report

  select * from emp where deptno = :P1_DEPT
  

  We create dynamic Action on the evolution of the P1_DEPT point. We will need two real actions:

  1-> set value action

  Set the Type - > body of the PL/SQL function

  The function of body - > return 1;

  Page item to submit-> P1_DEPT

  Change to delete-> Yes event

  Selecttion Type-> trigger element

  2. action-> Refresh

  Selecttion Type-> region

  Region-> your region of report

• NVL selection list does not not on the place where clause in query

  Ok. APEX 4.2...

  Im having problems with my selection lists and NULL values... I see that it has come time and time again...

  I have a tabular presentation, with a query based on a selection list.  The selection list has the ability to '- Show All -'... The value of the selection list is a number, and the display is words...  (for reference the LOV query is: select status, batch from pmt_stat_lookup by 1)

  Initially I had problems with null and invalid numbers like ' display Null = 'Yes' and the problem of null % ', so have used the code in this blog to remove the NULL values... Display Null = & amp; #34; Yes & amp; #34; and the problem of null % | Inside Oracle APEX by Patrick Wolf

  Then in the application of my report, I have a where clause clause that checks the value of the selection list... WHERE batch = nvl(:P11_STATUS_SELECT,STATUS_ID)

  everything works almost fine, and I can choose a status, or I choose - see the All-, but the query will not include the lines where the State is null.

  (I also see that maybe I should be, use the case statement instead of the NVL on where clause, but not sure of the syntax. In addition, NVL was used somewhat in the different reports in the application...)

  For reference, the code of the old blog that I as a process page is:

  BEGIN

  FOR rItem IN

  (SELECT NOM_ELEMENT

  OF APEX_APPLICATION_PAGE_ITEMS

  WHERE APPLICATION_ID = TO_NUMBER(:APP_ID)

  AND PAGE_ID IN (TO_NUMBER(:APP_PAGE_ID), 0)

  THEN

  END IF;

  END LOOP;

  END;

• Creation of a where clause clause in the LOV query box

  Hi guys is any able to help me with this one

  I have a page in my application where there down LOV down now values this menu drop-down comes from a table that looks like this

  users_for _form_TBL

  E_MAIL	Name of the vendor
  [email protected]	Oracle
  [email protected]	SAP
  [email protected]	IBM
  [email protected]	Oracle
  [email protected]	Intergraph

  So my syntax for the LOV I mentioned looks like this

  Select PROVIDER as display_value, SELLER as return_value

  of form_user_tab where email =: APP_USER

  order by 1;

  
  

  so if [email protected] connects to the application and to make a selection on the LOV it would only show suppliers compared to his E_MAIL like oracle, sap, IBM , and then he clicks the submit button on the page then the seller that he chose is inserted into another table. What I did on the table of insertion has been to create a trigger that after inserting a seller the trigger inserts a 1 in a column called assessed.

  What I did after that is add a select statement in the where clause of the LOV so that she would check in the table insert if this seller had been chosen before and not show them again to be selected my syntax, the second time around in the SQL query box has been

  Select PROVIDER as display_value, SELLER as return_value

  to users_for _form_TBL where email =: APP_USER

  and (select "seller", "ASSESSD' of _tbl inserted is null);

  order by 1;

  But im getting an error of ideas guys. Thank you

  im still get and error is the where the clause allowed in the second select statement

  He still has basic syntax errors. You posted 4 different "table names" whose only in the first query is valid so far. That can not see your database, I don't know what really is the name of these tables, and to what extent these is wrong helps your problem.

  I can tell that you are looking for:

  select
      u.vendor display_value
    , u.vendor return_value
  from
      users_for_form_tbl u
  where
      u.e_mail = :app_user

      u.vendor
  

  but the table names could be something else...

• Optimize query with function in where clause

  Hello

  I have a query like this:

  SELECT * FROM table_1 t
  WHERE
  (
  -- Clause A (very long clause that filters a lot of rows)
  )
  AND f(t.field) = 'Y' -- This function is heavy but it should filter few rows
  

  This query, it is very slow because I think he's trying to evaluate f() for all rows in table_1.

  Howerver, if I have database query:

  SELECT f(t.field) FROM table_1 t
  WHERE
  (
  -- very long clause that filters a lot of rows
  )
  

  It's very fast.

  How can I reference the query to filter the lines of division A, then by function?

  Thanks in advance!

  If you wrap the function in a select clause then the optimizer can use a scalar subquery caching:

  SELECT * FROM table_1 t 

  WHERE  (  -- Clause A (very long clause that filters a lot of rows)  ) 

  AND (Select f(t.field) From Dual) = 'Y' -- This function is heavy but it should filter few rows

  so I don't know if I'm wrong in the concept that I have. Kindly help.

  Your question is answered in the Performance Tuning Guide

  Using indexes and clusters

  14.1.4 choosing composite indexes

  A composite index contains several key columns. Composite indexes can provide additional benefits compared to the index to single column:

  • Improved selectivity

    Sometimes the two or more columns or expressions, each with a low selectivity can be combined to form a composite with a high selectivity.

  • Reduced IO

    If all columns selected by a query are a composite index, then Oracle may return these values in the index without access to the table.

  A SQL statement can use a path on a composite index if the statement contains constructions that use a main part of the index.

  Note:

  This is no longer the case with the skip index scans. See "Index Skip Scans".

  A main part of an index is a set of one or more columns that have been specified first and consecutively in the list of columns in the CREATE INDEX statement that created the index.

• Where clause causing a query slow down in a slider

  (p_user_category is a variable that is defined by the user, which may be zero if the user wants that all lines)

  ----

  c_results sys_refcursor;

  --

  Open the c_results for

  Select id

  description

  inventory

  from the_table

  where category = nvl (, p_user_category);

  extract the c_results in v_id, v_description, v_inventory;

  close c_results;

  ----

  Then, it takes five minutes to return even just a line when the p_user_category is null.

  However, if I change the where clause:

  ----

  where (p_user_category is null or category = p_user_category)

  ----

  then it returns all the rows immediately.

  He began to be a problem right at the time of the most recent update - I'm under 11.2.0.2.0 (production of 64 - bit).

  The optimizer is smart enough to recognize that null is null, then "nvl (null, category)' collapses 'category' and your 'category = nvl (null, category)' predicate is transformed into 'category is not null' (if it is allowed to be null) or simply - disappears for the test SQL is not the same as the executed PL/SQL.

  In PL/SQL rewrite your manual is not the same logicall than the original at least that you have said category to be non-null because your first testament leaking is to allow the rows with a null category to declare, while the original request would lose their.

  See the implementation plans for the SQL and PL/SQL versions.

• Tuning - using the CASE statement in the WHERE clause of the query

  Hi all
  
  My request has been changed to use a CASE statement in the WHERE clause to examine the data to some columns based on a parameter value. This modified request is made a full table and constantly running scan. Please suggest what can be done to improve its performance:
  
  Query:

  SELECT LAST_DAY(TRUNC(TO_TIMESTAMP(os.requestdatetime, 'yyyymmddhh24:mi:ss.ff4'))) AS summary_date,
  os.acctnum,
  os.avieworigin_refid,
  COUNT(1) cnt_articleview,
  SUM(NVL(autocompletedterm,0)) cnt_autocompletedterm
  FROM TABLE1 os
  WHERE os.acctnum IS NOT NULL
  AND os.avieworigin_refid IS NOT NULL
  AND os.requestdatetime IS NOT NULL
  AND UPPER(os.success_ind) = 'S'
  
  AND CASE WHEN
  Param_ValueToCheck  = 'FULL' AND get_date_timestamp(os.requestdatetime)  BETWEEN 
  TO_DATE('01-MAY-2011 00:00:00','DD-MON-YYYY HH24:MI:SS') AND
  TO_DATE('31-MAY-2011 00:00:00','DD-MON-YYYY HH24:MI:SS')
  THEN 1

  When it is executed individually, MERGE LOGIC 1 and LOGIC of MERGE 2 take about ten for a daterange of 30 days data.

  BUT FULL is to get the scores of APR - JUN, INCR becomes partitions for MAY so not both 30 days.
  Are compare us like with like?

• Setting in the WHERE clause of the query

  Hi all
  
  I have 2 tables.
  
  TABLE_A contains 10 million documents.
  TABLE_B contains 100 records.
  
  I associate myself with these 2 tables
  
  Here's a.ID left

  SELECT A.*, B.*
  FROM TABLE_A a, TABLE_B b
  WHERE a.ID = b.ID;

  Here's b.ID left

  SELECT A.*, B.*
  FROM TABLE_A a, TABLE_B b
  WHERE b.ID = a.ID;

  My question is what query will give better performance? I thought that, if we put the column in the table with a lower number of lines on the left, then it will be faster than the other.

  In current versions of Oracle, it does not matter in what order you sum-up your predicates in the WHERE clause of a query: they will be optimized/executed in a way even.

• where clause to query the hierarchy in the tree Apex area does not

  Hi all

  I am building a tree Menu in Apex 5.0.3 (Oracle 11 g XE), when using when the clause, it does show all the data, but without him, showing all the data.

  I'm trying to populate Tree Menu with data specific to a user successfully logged on.

  (A) table created as HR2. TREE_MENU

  menu_name varchar2 (50).

  number of menu_parent

  number of menu_child

  menu_id varchar2 (12),

  menu_path varchar2 (100),

  number of user_no

  (B) SQL statement for the tree in the Apex region

  Select case when connect_by_isleaf = 1 then 0

  When level = 1 then 1

  else                           -1

  end the status,

  level,

  'Menu_name' as the title,

  NULL as an icon,

  "MENU_CHILD" as a value.

  NULL as ToolTip,

  NULL as link

  to HR2. "" TREE_MENU ".

  -WHERE USER_NO =: P_USERNO

  Start with 'MENU_CHILD' is null

  connect prior "MENU_PARENT" = "MENU_CHILD."

  brothers and sisters of order by 'MENU_ID '.

  Note: also used static value where clause but is not workd.

  that the mistake of me or something else? When using the wizard, she asks (possibly) where clause, this means that when the clause can be used in the SQL statement.

  Help, please.

  Kind regards.

  If you want to prune your tree to show only the elements of the No. 7 usermenu, copy the following code helps you

  select case when connect_by_isleaf = 1 then 0
              when level = 1             then 1
              else                           -1
         end as status,
         level,
         "MENU_NAME" as title,
         null as icon,
         "MENU_CHILD" as value,
         null as tooltip,
         null as link
  from HR2."TREE_MENU"
  start with "MENU_CHILD" is null
  connect by
      prior "MENU_PARENT" = "MENU_CHILD"
      and "USER_NO" = 7
  order siblings by "MENU_ID"
