• How to add a where condition to seeds VO

  Hi I have a VO PoRequisitionLinesVO.Now knowledge I want to add the SQL where condition...

  How can I do this...? There is no addition of all fields... only adding a where condition clause?

  Will I need to extend that VO? If yes then how should I do this?

  Thank you...

  Yes, you must extend the VO.

  To get the procedure you can search the Internet, there is a great article (that I mentioned below):

• Condition within a where condition clause

  Dear friends,
  I am a beginner in PL/SQL and I need your help.
  I'll show you my code (it does not):
  

  declare
      var_mese VARCHAR2 (2);
  begin
      select max(to_number(MESE)) 
      into var_mese
      from NOC_MONITORAGGIO;
         SELECT count(*)
          FROM noc_sdoc_work a,
               noc_sdoc b,
               NOC_MONITORAGGIO
         WHERE NVL(a.CD_STRUTTURA,'x') = NVL(b.CD_STRUTTURA,'x')
           AND NVL(a.CD_SUB_STRUTTURA,'x') = NVL(b.CD_SUB_STRUTTURA,'x')
           AND NVL(a.NR_PRATICA,'x') = NVL(b.NR_PRATICA,'x')
           AND NVL(a.ASL,'x') = NVL(b.ASL,'x')
           AND b.STATO IN ( 1, 2 )         
          and
              if  var_mese in ('03','04','05','06','07','08','09','10','11','12') then

  My problem is here:

  You can code box that using a statement in the WHERE clause:

   and NOC_MONITORAGGIO.ANNO_GESTIONE =
              case
                 when var_mese in ('03','04','05','06','07','08','09','10','11','12') then b.ANNO
                 else to_number(b.ANNO)-1

• WHERE condition in a sql statement

  Hello people,

  I have a screen with data grid where one of the columns is STATES_CODES and other VOLUMES one. Grid consists of several lines. I need to create a CUSTOM SEARCH field that will be filtering on this database.

  Unfortunately a customer wants to enter a search string with custom functions: '+' (plus) to include in the selection of the result and "-" (less) to exclude from the selection of the results. For example: "+ IT + -100". Based on this string, I need to return only the States HE and and exclude volumes with a value of 100.

  A tip how to build a query where condition, so it will be more effective as possible?

  Simple example:

  test data:

  with t (select 'IT' State, volume 90 of any union double

  Select 'IT' State, 100 volumes of all the double union

  Select 'IT' State, 100 volumes of all the double union

  Select 'OF' State, 90 volume of all the double union

  Select 'OF' State, in 100 volumes of all the double union

  Select 'OF' State, in 100 volumes of all the double union

  Select 'NL' State, 90 volume of all the double union

  Select 'NL' State, 100 volumes of all the double union

  Select 'NL' State, 100 volumes of all the double union

  Select 'FR' State, 90 volume of all the double union

  Select 'FR' State, in 100 volumes of all the double union

  Select 'FR' State, in 100 volumes of all the double union

  Select 'ARE' State, 90 volume of all the double union

  Select 'ARE' State, in 100 volumes of all the double union

  Select 'ARE' State, 100 volumes of double

  )

  Select * from t

  Search string: "+ IT + - 100".

  I thought to somehow using regular expressions REGEXP_LIKE condition, but do not know how to change the entered search string in above format as long as the regular expression.

  And if you want to be specific about the characters representing the State and the numbers represent the amount then you will need to divide them into more...

  SQL > with t (select 'IT' State, 90 volume of all the double union)
  2 Select 'IT' State, 100 volumes of all the double union
  3 select 'IT' State, 100 volumes of all the double union
  4. Select 'FROM' State, 90 volume of all the double union

  
  5. Select 'FROM' State, in 100 volumes of all the double union
  6. Select 'FROM' State, in 100 volumes of all the double union
  7 select 'NL' State, 90 volume of all the double union
  8 select 'NL' State, 100 volumes of all the double union
  9 select 'NL' State, 100 volumes of all the double union
  10. Select 'FR' State, 90 volume of all the double union
  11. Select 'FR' State, in 100 volumes of all the double union
  12. Select 'FR' State, in 100 volumes of all the double union

• SQL only: WHERE Condition pulled the correct runtime of the Central "SQL" tab

  I have a requirement that seems like it should be easy to solve in SQL, but me seems to be stuck with blinders and can't see the solution.
  
  The 'problem' that I'm trying to solve is to get several reporting units to any use of the SQL even in their where clause for certain types of metrics reports. So this is the solution I am proposing that we store the sql in a central table, which, in a simplified form, would have two columns as:
  
  GroupName Varchar2 (2000)
  SQL_Filter Varchar2 (5000)
  
  
  What I want to do conceptual, it's allow the user (even if they're using MS - SQL) to
  
  
  WHERE FunctionName (GetSQL_ForGroupName)
  
  But first of all, I would tell them that this can be done in Oracle sql. However, I can't understand how to achieve this end. From what I've read so far that oracle will not do:
  
  WHERE (subquery that returns SQL)
  
  or (in SQL)
  
  WHERE VariableSubstition
  
  or
  
  WHERE FunctionName (GetSQL_ForGroupName)
  
  It seems that these things in the WHERE clause allows Oracle after only
  
  FieldName [operator]
  
  as in
  
  WHERE price > (subquery)
  
  or
  
  WHERE ID IN (Value) Function
  
  Is it possible to do a subquery (or anything else) that allows me to draw the where clause running SQL - using only SQL? I can do this with a stored procedure, but it is to say it seems to me I had start coding select specific instructions for them or code so that they could enter select statements (or joins etc.). I don't want to write a complete dynamic reporting engine. I want to do is be able to pull the sql running. This ensures that everyone is 1) with the good sql for metrics 2) by using the same sql and 3) the core sql parameters can be stored in one place instead of 3000 definitions of the various reports.
  
  I must be looking at this the wrong way, I think. The solution does NOT seem to do WHERE (pull in the SQL running)... but I was not able to find a different way of thinking. For example, WITH does not resolve as you immediately the requirement WHERE fieldname [operator] [subquery | function]. I was browsing the internet and looking through all the books SQL on Safari of O'reilly but I have not met a solution. However, I think, this issue of 'centralization of base SQL' must have been resolved several, several times previously. Why can't I find anything on it then?
  
  Brad

  You might use a pipeline function to return a TABLE object. This function accepts a parameter that contains the name of the Group (although "GetSQL_ForGroupName" is supposed to represent). The query that they deliver will then look something like this:

  SELECT column_list
  FROM   TABLE(table_function('GroupName'))
  WHERE  additional_conditions
  

  In the function, you can create the SELECT statement that channels the rows in the table with WHERE conditions pulled a table for the provided group name.

• explain query plan uses no unique index with where condition

  Hi all

  I use in the 10.2.0.5 oracle database Enterprise edition 64-bit on 64-bit windows server 2008.

  I'm following this tutorial on my own table

  Guide to understanding Oracle QUERY PLAN - 10 minutes

  my questions are below

  Analyze table LIB_CLASSIFICATIONS compute statistics;
  explain plan for  SELECT class_id  FROM lib_classifications WHERE class_no = '538' ;
  select * from table(dbms_xplan.display);
  

  the result is less than

  Hash value of plan: 3022072076

  | ID | Operation | Name                | Lines | Bytes | Cost (% CPU). Time |

  MODIFY_USER VARCHAR2 (10)

  CREATE_DATE DATE

  CLASS_CATEGORY_ID VARCHAR2 (10)

  class_id has a primary key.

  now when I remove the condition where the query, the result is lower;

  Analyze table LIB_CLASSIFICATIONS compute statistics;
  explain plan for  SELECT class_id  FROM lib_classifications ;
  select * from table(dbms_xplan.display);
  

  the result is less than

  Hash value of plan: 262704430

  ------------------------------------------------------------------------------------

  now it's using indexes with INDEX FAST FULL SCAN.

  I need the index using the WHERE condition as well.

  How to do this?

  Thank you.

  you have indexes on the column class_id not on class_no column how u would expect index to use when there is no index on the column class_no

• How to make a sum of text_field or column with where condition?

  Hi all

  In Oracle forms 6i, I created a form in which there are 5 text_Items (with 20 none of the displayed fields) namely ACCOUNT FD DO, AMOUNT, INTEREST RATE, STATUS and INTEREST_YEAR.

  FD ACCOUNT NO.	AMOUNT	INTEREST RATE	STATUS	INTEREST_YEAR
  47665	50000	11.5	E	5750
  37463	60000	12	D	7200
  47651

  100000

  1. 12.5

  D

  12500

  34766

  70000

  11

  E

  7700

  I want to make the sum of the INTEREST_YEAR where status = 'E '.

  I created a TOTAL_INTEREST_YEAR name field in which I want to display the sum.

  How the sum with where condition?

  Thank you.

  Michael,

  When you write the formula for a calculated item, it does not use PL/SQL expressions (to include built-in DECODING) in Forms 6i.  If there was no conditional control over your calculation, you can simply make your article a summary point and perform the summation over column interest_rate .  However, because your calculation depends on the value in the STATUS column, you will need to use a combination of a calculated item and a summary article because you can't use an IF, DECODE or any other PL/SQL statement in the formula for the calculated item.  Therefore, you need to create a function in the knot of program units and call the function in your formula.  I tested it using the following code and it worked correctly.

  First, create the following function in the node of the object browser program units.

  FUNCTION calc_interest RETURN NUMBER IS
       n_ret_val  NUMBER := 0;
   BEGIN
     IF ( :YOUR_BLOCK.STATUS = 'E' ) THEN
         n_ret_val := :YOUR_BLOCK.interest_rate;
     END IF;
     RETURN n_ret_val;
  END calc_interest;
  

  First, you must change the property to BLOCK request all archives = Yes

  Then, open the palette of your calculated item property, and set the following properties:

  1. calculation = Formula

  2 property Forumla = CALC_INTEREST

  3. point data base = No.

  Now create a second item in the table not based on in your block that will display the amount of the interests summarized.  Open the palette property for this element and set the following properties:

  1 Data Type = number

  2 calculation Mode = Summary

  3. function = sum

  4 summarizes point = "name of your element calculated.

  5 base of data point = No.

  6 canvas = "your canvas.

  When you query your block, you should see the sum of all records where STATUS = 'E '.

  It worked for me, in my example form that I created so this should work for you.

• questioning... where column_name is not null

  Hi all
  I have a table that contains documents 160 million (140 GB) and I need to interview as below...
  
  Select max (start_date) from table_name where column_name is not null
  
  No clue on column_name and most of the values is NULL value, but I want data wherever the values in the columns are not null
  The query should not be used in application but to check some data and it takes more than 2 hours and no results yet.
  
  Can anyone of you help me to write the request in the best way...
  
  Thank you

  He has no choice but to do a full table without index scan.

  So the only option I know to speed it up would be to use at the same time. You have a license for the parallel option?

  select /*+ parallel (4) */ max(start_date) from table_name where column_name is not null
  

  And when you do things like this you want to do as much as you can at the same time since the 2nd, 3rd, etc. are basically free. Which means you might as well do MIN, MAX on other columns, on what you might need them.

• Shot summary of a where condition clause...

  I have a form that displays the code material and this number in which different warehouses...
  
  It is possible to create an element of the summary screen is based on the place where the condition
  
  for ex.

  SQL> select  sum(arar) from tbs;
  
   SUM(ARAR)
  ----------
        1488
  
  for this query i can create a  display item and in the propery  pallete  i can select mode as summary,
  summary function as count, and select respective block and item...
  
  what i want to know is can this be based on where condition 
  some thing like the count shoudn't include where the column values is zero
  SQL> select count(arar) from tbs where arar!='0';
  
  COUNT(ARAR)
  -----------
          144

  Hello

  Create a column of formulas no database in the same block to say 'NON_ZERO.
  The formula for the column would be: SET_NON_ZERO - this function returns 1 if arar is non-zero and 0 if it is zero.

  FUNCTION SET_NON_ZERO RETURN NUMBER IS
  BEGIN
   IF :ARAR = 0 THEN
     RETURN (0);
   ELSE
     RETURN (1);
   END IF;
  END;
  

  Now you can create a column of synthesis and use the text-to-speech function 'sum' and item summarised as "NON_ZERO.

  I hope this helps.

  Best regards

• ADF: Re-apply the where condition of a view object and updating table

  Hello
  
  I have a table for documents, with columns for the title of document, document type and so on. There is also a column called "receiver".
  In the viewobject based on the table, I have a condition that only the lines where the receiver is null should be included. In other words: only documents unassigned should be indicated in the table.
  
  The purpose of the page that contains the table is to assign documents to the receivers. The idea is that the user enters a name in the column of a receiver or several lines and then press a button of validation.
  When a line - a document - has been assigned to a receiver and the change is committed, this line is more fills the where of the viewobject condition and I would like my page to reflect the fact that. In other words: as soon as one or more lines have been assigned to a receiver and the changes are committed, the lines should disappear from the table and the page.
  
  What is the best way to achieve this?
  
  Kind regards
  Andreas

  To do this is to add a navigation case to the same page and use this case to navigation after validation. Should run the query again, it costs you a full page sent.

  Another way to do the validation and the use of a managed method bean to re run the iterator.
