  A basic concept that is important to understand - sliders aren't 'sets of results' (sets of data in memory). A cursor is a series of executable steps (see plans run to cursor). It's like a program. An extraction run the program and output data. In general, which is repeated until the cursor (aka program) is no longer found the corresponding lines.

  A ref cursor is a pointer or a handle for a such slider, passed to a caller, allowing the appellant to interface directly with this slider/program.

  The slider more effective to create a search would be one without superfluous code and predicates and filters. Consider the following approach - a beefier PL/SQL procedure, do not try and play little tricks with SQL predicates in an attempt to create one (and probably not optimal) SQL.

  (not tested/compiled code)

  create or replace procedure SearchAddress(
    town     IN SEARCHADDRESS.TOWN%TYPE,
    street   IN SEARCHADDRESS.STREET%TYPE,
    postcode IN SEARCHADDRESS.POSTCODE%TYPE,
    refCur out ref_cursor
  ) is
    curHandle integer;
    res integer;
    searchSQL varchar2(1000);
  begin
    -- create base query
    searchSQL := 'select searchaddress_pk from searchaddress where 1 = 1 ';
  
    -- add dynamic predicates as needed
    if town is not null then
      searchSQL := searchSQL || 'and town = :town';
    end if;
  
    if street is not null then
      searchSQL := searchSQL || ' and street = :street';
    end if;
  
    if postcode is not null then
      searchSQL := searchSQL || ' and postcode = :postcode';
    end if;
  
    -- create a DBMS_SQL cursor
    curHandle := DBMS_SQL.open_cursor;
    DBMS_SQL.parse( curHandle, searchSQL, DBMS_SQL.NATIVE );
  
     -- bind the dynamic bind variables added as predicate values
    if town is not null then
      DBMS_SQL.Bind_Variable( curHandle, 'town', town );
    end if;
  
    if street is not null then
      DBMS_SQL.Bind_Variable( curHandle, 'street', street );
    end if;
  
    if postcode is not null then
      DBMS_SQL.Bind_Variable( curHandle, 'postcode', postcode );
    end if;
  
    -- execute cursor (to create the cursor program) and pass it back as a ref cursor

• Setting of outsourcing work is not for a SQL Where clause

  Im trying to outsource the WHERE SQL clause of a snapshot data (connecting to Siebel DB) and specify where clause in the run profile that does not work.

  Snapshot of research: Select the name of siebel.s_org_ext

  Parameter of outsourcing: where_clause_sql

  Run the content of the profile:
  

  phase. Phase1.snapshot.clt.where_clause_sql = name = "ABC0009".

  #phase. Phase1.snapshot.clt.snapshot_sql = select name from siebel.s_org_ext where name = 'ABC0009 '.

  The above parameter retrieves all the records in the table. Below the profile execution retrieves just this record that seems to work fine.

  
  

  Run the content of the profile:
  

  phase. Phase1.snapshot.clt.snapshot_sql = select name from siebel.s_org_ext where name = 'ABC0009 '.

  
  

  I want to outsource only where clause as there are many SQL and they are huge to maintain in the run profile.

  I have attached a doco with screenshots that will help to understand more.

  Hello

  You must BE

  -Choose "Select table or view" in the table of the snapshot Wizard selection page

  &

  -Use outsourced where clause

  OR

  -Choose "SQL" in the snapshot table selection wizard page.

  &

  -Outsourced use SQL snapshot

  You can't mix and match options.

• dynamic logic in SQL WHERE clause based on the value of the ELEMENT

  Hello
  
  I have a report based on the following SQL query.
  

     select dept_no,
         dept_name,
         dept_loc
    from dept
   where dept_loc = :P1_DEPT_LOC
     // If P1_DEPT_LOC is not null, I want the WHERE clause and IF  P1_DEPT_LOC is null, then I don't need the WHERE clause.
     // how can I build this logic in same SQL

  Thank you
  Deepak
  
  Published by: Deepak_J on March 11, 2010 16:37

  where: P1_DEPT_LOC IS NULL or dept_loc =: P1_DEPT_LOC

  If dept_loc is not null better would be

  where dept_loc = coalesce(:P1_DEPT_LOC,dept_loc)

• Simple conditional SQL WHERE Clause with two Subselects

  Hi SQL Experts,
  I need some quick help with a query.
  It is a ' select ' for a data source object repository phyiscal table OBI.
  So, I can't put in PL/SQL or in stored procedures. I just need
  have two conditions / selects different according to the user's role (this information comes
  of the session).
  The above does not work:

  -ORA00905. 00000 - 'lack the key word'
  SELECT OFFICENO FROM orgunit
  WHERE
  
  BOX WHEN "SESSION_VARIABLE' LIKE '% globalmanager %' THEN
  ASSIGNEDOFFICES =
  (
  SELECT DISTINCT ASSIGNEDOFFICES
  FROM USERSTABLE INNER JOIN orgunit WE
  OrgUnit. KEY = USERSTABLE. OFFICE
  WHERE USERSTABLE. USERNAME ='VALUEOF (NQ_SESSION. THE USER)"
  )
  ON THE OTHER
  OFFICENO =
  (
  SELECT DISTINCT USERSTABLE OFFICENO
  INNER JOIN orgunit WE
  OrgUnit. KEY = USERSTABLE. OFFICE
  WHERE USERSTABLE. USERNAME ='VALUEOF (NQ_SESSION. THE USER)"
  )
  END;

  Can anyone help?

  Hello

  I can't tell what you want to do by looking at the code that do not do. Maybe:

  SELECT officeno

  For orgunit

  WHERE (session_variable LIKE '% globalmanager %'

  AND IN assignedofficies

  (

  SELECT assignedoffices

  UserTable U1

  JOIN orgunit o1 ON o1.officekey = u1.officekey

  WHERE u1.username = ' VALUEOF (NQ_SESSION. THE USER)"

  )

  )

  OR (NVL (session_variable

  , '?'

  ) NOT LIKE '% globalmanager % '.

  AND IN officeno

  (

  SELECT officeno

  Of u2 usertable

  JOIN orgunit o2 ON o2.officekey = u2.officekey

  WHERE u2.username = ' VALUEOF (NQ_SESSION. THE USER)"

  )

  )

  ;

  There might be a simpler and more efficient way in function your tables and your limit.

  The condition u2.username = ' VALUEOF (NQ_SESSION. The USER) "almost certainly not what you really want.

  .

  Whenever you have any questions, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
  Explain, using specific examples, how you get these results from these data.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  Hello

  The problem is due to the "OR" condition (I did not pay attention to it earlier).

  Because of this condition, your query is given beyond 7 days recovery. You need to rewrite the code as:

  ALM_OG_CAMPAIGN_CODE in ('MED', 'MED1')
  

  Instead of

     and ALM_OG_CAMPAIGN_CODE = 'MED'
       OR ALM_OG_CAMPAIGN_CODE = 'MED1';
  

  This will do the magic for you.

• For UNION in VOImpl SQL WHERE clause

  Hey gurus,
  
  I need the ability to add a condition to VOImpl to user_id for two queries in a UNION statement. However, setWhereClause only adds condition at the end of the query. Any suggestions? I tried to make a selection online and could not because of the 'double '.
  
  Thank you

  When user_id = 16448

  You can have the condition at the request of origin itself and in the VOImpl, just switch the setting.

  select 'Sys' x from dual where exists (
  select responsibility_name from fnd_user_responsibility fur,
  fnd_responsibility_tl frt
  where user_id = :1
  and frt.responsibility_id = fur.responsibility_id

• Problem SQL querry (case statement...)

  Hi to everyone who reads this.
  
  I have a huge problem (at least for me) with a SQL I try to write in Oracle forms6 (yes I know... old app).
  
  OK, here it goes...
  
  We have a table like:
  

  create table temp (
    year     number 
    month    number,
    konto    number,
    DEBET    number, 
    KREDIT   number,
    date_tr  date,
    ind      number
  );

  The data in the table are:
  

   YEAR        MONTH    KONTO      DEBET     KREDIT DATE_TR  IND
  ---------- ---------- ----- ---------- ---------- -------- -
        2011          1 12101   4674,32           0 05.06.11
        2011          6 12101  -4674,32           0 05.06.11 R
        2011          6 12182   4674,32           0          R

  Now, to explain a little what I want to do...
  

  case when p_date > NVL(date_tr,'01012004') then
  date_tr is null;
  else
  ind is null
  end

  What I need is when p_date is entered by a user SQL should check if the date is less or greater than date_tr...
  in this case it should show only the record that has a null value in date_tr cullum.
  
  Or if it isn't... it should display records which is null in ind cullum.
  
  
  The main problem is that I do not know how to write the case statement in SQLs where clause... maybe someone can give me a hint
  or a partial code how do I solve this problem.
  
  Any ideas would be greatly apreciated.
  
  Thanks to you all!

  I was wonering just if there is a way to set the WHERE clause of the query that the session variable?  I have the following so far and have tried to go through a ton of tutorials, but it doesn't seem to work.  Is it still possible?  I don't know what follows is wrong, but can someone help me with changing the following code, or pointing me to a good tutorial?  (I write it with PHP)

  $query = "SELECT * from members where user_id = ' $_SESSION ['members']";

  Thanks for your help.

  $member = "-1";
  If (isset($_SESSION['members'])) {}
  $member = $_SESSION ['members'];

  }
  $query = "SELECT * from members where user_id = $member;

• How to set SQL that contains 'in' where clause in VO?

  I don't want to set "in" would adopt a kind of programatical in VO as below. I want to use a method declariable to set in the clause using bindings varaible.

  It can be implemented?

      private String getInClauseWithParamNames(List termCodes) {
             //logic to form the in clause with multiple bind variables
             StringBuffer inClause = new StringBuffer(); 
             if(termCodes !=null){
                 for (int i = 1; i < termCodes.size() + 1; i++) { 
                     inClause.append(":termC" + (i));
                     if (i < termCodes.size()) { 
                        inClause.append(","); 
                     } 
                 }
             }
             return inClause.toString();
      }
          
      public Row[] getYardFixedSlots(List termCodes) {
          if(termCodes != null && !termCodes.isEmpty()){
              String inClause = getInClauseWithParamNames(termCodes);
              //setting the where cluase to use the generated in clause
              this.setWhereClause("YardFixedSlot.TERMINAL_C in (" + inClause + ")");
              ////clearing all existing where clause params if any 
              this.setWhereClauseParams(null);
              if(getVariableManager() !=null){
                 this.getVariableManager().clearVariables();
              }
              //setting values for all bind variables one by one in the in clause
              for (int i = 0; i < termCodes.size(); i++) { 
                  //defining the named bind variables programatically 
                  this.defineNamedWhereClauseParam("termC" + (i + 1), null, null);
                  //setting the value for each named bind variable 
                  this.setNamedWhereClauseParam("termC" + (i + 1), termCodes.get(i)); 
              }
              this.setRangeSize(-1); 
              //executing the query 
              this.executeQuery(); 
          }
          //returning the rows from query result 
          return this.getAllRowsInRange(); 
      }
  

  You can only use the link as a parameter to the in clause. You must divide the string inside the binding variable. Sample can be found at decompilation binary ADF: using bind variable for SQL statements with the paragraph

• Can I use truncated and where clause in the statement even?

  Hello guys,.
  
  Can I use truncated with where clause in the same statement.
  
  
  For ex:
  
  TRUNCATE TABLE my_table WHERE id < 500;
  
  If not, that you recommend me to overtemperature to the level of high water line?
  
  
  By the way

  Okay I need an increasing amount of space. However, at the same time I want to recover the spaces empty below HWM. So, I need to use less amount of space I am inserting. Therefore, shouldn't use retractable for this?
  >
  Why waste the effort. Oracle will reuse the space below the HWM when doing inserts. You already said that you insert more lines you delete so all these will be more accustomed to the top.

  The only time where that oracle may not use space is when the space is too small to be useful. It is documented in the doc, I told you
  >
  Understanding recoverable unused space
  Over time, Update, and Delete on objects within a tablespace can create pockets of empty space that individually are not large enough to be reused for the new data.
  >
  Most uses of CONTRACTION I've seen are totally useless. If you follow the doc and run the Advisor of segment it will tell you if there is space that can be retrieved and how much. But, even once, for your use even if case will get you will Oracle while you need to reassign the new extensions, then the HWM will just go still higher.

  If pay you a heavy price in Oracle did a full table scan, update of many blocks from the table, update THE index, impact performance for other users to access the table during the SHRINK and reallocate extensions (maybe even some of the same areas) when you insert more data.

  Do not SHRINK unless you know it's necessary.

• using case when statement or decode unfavorable in where clause

  Hi the gems...
  
  I have a problem in the following query...
  I try to use when case statement in where clause of a select query.
  
  
  Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
  CR. Salary salary
  of customer_details cr
  where (case when ' > ' = ' > ' then ' cr.salary > 5000')
  When ' > ' = ' < ' then ' cr.salary < 5000'
  When ' > ' = '=' and then 'cr.salary = 5000'
  Another null
  (end);
  
  
  the expression in the when clause of the statement of the case, when comes from HQ and according to the choice I have to make the where clause.
  That is why, for the execution of the query, I put ' > ' in this place.
  
  If the original query will look like this (for reference):
  
  Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
  CR. Salary salary
  of customer_details cr
  where (case when variable = ' > ' then ' cr.salary > 5000')
  When the variable = ' < ' then ' cr.salary < 5000'
  When the variable = '=' and then 'cr.salary = 5000'
  Another null
  (end);
  
  
  so, in a real case, if the user selects ' > ' then the filter will be ' where cr.salary > 5000.
  If the user selects ' < ' then the filter will be ' where cr.salary < 5000.
  If the user selects '=', then the filter will be 'where cr.salary = 5000 '.
  
  but I get the error "ORA 00920:invalid relational operator.
  
  Help, please... Thanks in advance...

  Hello

  select cr.customer_name || ' - ' ||cr.customer_number as cust_name,
         cr.salary                                      as salary
   from customer_details cr
  where (    v_variable = 'bigger'
         and cr.salary > 5000
        )
     or (    v_variable = 'less'
        and cr.salary < 5000
         )
     or (    v_variable = 'eq'
          and cr.salary = 5000
         )

• Update statement with joins of tables and where Clause

  Hi, I have MS SQL background and I try to execute an update statement in Oracle with joins of tables. However, the syntax below does not work but I think it works for MS SQL.
  
  Basically, the base table must be attached to a master table trend with monthly snapshots, an account will be only an entry for a given date monthly. Where clause must be limited to accounts within a certain range of interest rates.
  
  The first approach returns command SQL ORA-00933 not correctly completed, and the second approach returns ORA-01427 row below query returns multiple rows. Can anyone help? Thanks in advance!
  
  
  
  1:
  
  Update PenaltyAll
  Set a.indicator = month (b.)
  of PenaltyAll an inner join Master b on a.acctno = b.accountnumber
  where a.monthend='01/31/2009' and b.date='12/31/2008' and b.apr < 20
  
  2:
  
  Update PenaltyAll
  adjustment indicator =
  (select to_char (b., 'MM')
  of PenaltyAll an inner join Master b on a.acctno = b.accountnumber
  "where to_char (a.monthend,'mm/dd/yyyy ') = 31 January 2009"

  and b.apr < 20)
