• How to swap two values without using the third variable using the procedure

  How to exchange the two values without using the third variable using the procedure?
  
  In a procedure using two mode we pass two values A = x and B = y, and let us pass parameters to receive the output has A = y and B = x without using the third variable
  
  Published by: Millar on August 19, 2012 11:23

  Your question doesn't seem wise. As written, there is no reason to a third variable, just

  CREATE OR REPLACE PROCEDURE(
    x IN number,
    y IN number,
    a OUT number,
    b OUT number
  )
  AS
  BEGIN
    a := y;
    b := x;
  END;
  

  If it's an interview question, I suspect that the intention was that you had two settings IN OUT and you wanted to swap the values without the help of a third variable.

• Setting a value to variable using an sql and javascript

  Hello
  
  I'm trying to be a value of variables using javascript and sql. The code is as below:
  
  
  < script >
  function getDueDate() {}
  function getVal (item) {}
  If ($x (point) .value! = "")
  Return parseFloat ($x (item) .value);
  on the other
  Returns a null value.
  }
  $x('P26_DUE_DATE').value = select sysdate + $x ('P26_PAY_TERM') of the double
  }
  < /script >
  
  Can this be achieved?

  Hello

  JS and SQL are 2 different languages, so you can't do what you want to do using this script. The good thing is that you can still do so using JS.

  $x('P26_DUE_DATE').value = select sysdate + $x ('P26_PAY_TERM') of the double

  the "Select Sysdate" try to use the date JS Object (http://www.w3schools.com/jS/js_obj_date.asp) to add dates together.

• The use of bind variables (in &amp; out) with sql dynamic

  I have a table that contains code snippets to make postings on a set of pl/sql database. what the code does is basically receives an ID and returns a number of errors found.
  To run the code, I use dynamic sql with two bind variables.
  
  When codes consists of a simpel query, it works like a charm, for example with this code:
  

  BEGIN
     SELECT COUNT (1)
     INTO :1
     FROM articles atl
     WHERE ATL.CSE_ID = :2 AND cgp_id IS NULL;
  END;

  However when I get to post more complexes that must perform calculations or run several queries I run into trouble.
  I have boiled down the problem into that:
  

  DECLARE
     counter   NUMBER;
     my_id     NUMBER := 61;
  BEGIN
     EXECUTE IMMEDIATE ('
        declare 
           some_var number;
        begin
        
        select 1 into some_var from dual
        where :2 = 61; 
        
        :1 := :2;
        end;
  ')
        USING OUT counter, IN my_id;
  
     DBMS_OUTPUT.put_line (counter || '-' || my_id);
  END;

  This code is not really make sense, but it's just to show you what is the problem. When I run this code, I get the error
  ORA-6537 ON bind variable linked to a position IN
  
  The error doesn't seem wise,: 2 is the only one IN bind variable and it is only used in a where clause clause.
  As soon as I remove this where clause, the code works again (giving me 61-61, in case you want to know).
  
  Any idea what goes wrong? I just use bind variables in a way that you're not supposed to use it?
  
  I'm using Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit

  Correction. With immediate execution , the binding is in position, but binds do not need to be repeated. My statement above is incorrect...

  You must link only once - but bind by position. And the connection must correspond to the use of the variable binding.

  If the connection never variable assigns a value in the code, link by in.

  If the binding variable assigns a value in the code, link as OUTPUT.

  If the binding variable assigns a value and is used a variable in another statement in the code, link as IN OUT.

  For example

  SQL> create or replace procedure FooProc is
    2          cnt     number;
    3          id      number := 61;

    5          execute immediate
    6  'declare
    7          n       number;
    8  begin
    9          select
   10                  1 into n
   11          from dual
   12          where :var1 = 61;       --// var1 is used as IN
   13
   14          :var2 := n * :var1;     --// var2 is used as OUT and var1 as IN
   15          :var2 := -1 * :var2;    --// var2 is used as OUT and IN
   16  end;
   17  '
   18          using
   19                  in out id, in out cnt;  --// must reflect usage above
   20
   21          DBMS_OUTPUT.put_line ( 'cnt='||cnt || ' id=' || id);
   22  end;

• definition of variables in packages and using the same variables in charge Plans as a case statement in Odi

  Hello

  I am trying to use a global variable 'Global.test' in my ODI "pkg_test" package and step declaration type as a variable that is defined with the value 1 when my package evaluates the condition successfully run and with 0 if the fails.now condition I will carry out the same "pkg_test" package in my load "LP_TEST" and using the variable 'Global.test' Plan as a case statement in terms of load "LP_TEST".

  It's workload Odi is unable to understand the value of the variable 'Global.test', which is defined in my pkg 'pkg_test' and my case statement is put down in my care Plan.

  Thank you

  Hi Santosh Pradhan,

  What kind of story do you have in your variable?

  If you have not selected any antecedent, the scope of the variable is limited to the session. As the execution of the package is a session in its own (independent of the workload performance), the value of the variable is not accessible after his execution.

  You can also try assigning / updating of the value of the variable directly from your plan, instead of in the package:

  

  It will be useful.

• Use of system variables in the configs

  Hello

  I need to build strings using java system variables and place them in tangosol-coherence - override.xml

  I need something like this:

  <init-params>
      <init-param>
          <param-type>java.lang.String</param-type>
          <param-value>${somePath}/coherence/cache-config.xml</param-value>
      </init-param/>
  </init-params>
  

  Can I use a placeholder in the form ${some} to be replaced by the variable system during execution?

  Thank you in advance!

  I assume you mean the system property.

  You should be able to use syntax like this.

  / Home/myaccount/Coherence/cache-config. XML

  Then the system my.own.cache.config set property just to substitute it at runtime, for example, "/ home/otheraccount/coherence/cache-config.xml".

  Thank you
  Madhu K.

  I guess that SAMPLE is considered as a special case, and is not considered as something that takes a 'value' in the same way as values in where clause or values in the query itself.
  Let's face it, the SAMPLE is not the standard SQL syntax and is probably something Oracle implements in a separate thread for processing SQL itself i.e. engine Oracle saying to herself... "I will remember this bit of the sample until I questioned the data using the SQL engine, so I'll take a suitable sample of the results," but it's the SQL engine treats the binding of values and the Oracle process that awaits the results taste, knows nothing of the binding values in it's special EXAMPLE of keyword.

• Impossible to filter a recordset using a session variable

  I have a voluntary application page, then when volunteers press < Submit > their info is stored in a MySQl db table and a session variable is created containing the primary key of the record in the table, control is passed to a page of 'success' The success page accesses the session variable (I proved this by displaying the session on the success page variable) so my next step was to create a recordset in the success with a filter page using the session variable to select the appropriate line in the table, allowing me to view the volunteer to the info They argued.

  I created a page to pass the test that displays the session variable and a field of the volunteer info. When I test this I can't see the session variable is displayed, but the corresponding volunteer info of the recordset field is not displayed.

  The volunteer application page is here www.hollisterairshow.com/volunteerapp.php and the successpage is here www.hollisterairshow.com/thanksvol.php

  The code that creates the session variable in the voluntary application page is displayed below

  $_SESSION ['volunteer_id'] = mysql_insert_id();

  The code to display the session variable in the success page is shown below

  <? PHP echo $_SESSION ['volunteer_id'];? >

  The code to display the volunteer info is shown below

  Thank you < h1 > <? PHP echo $row_rsVolunteerApp ["FirstName"];? >! < / h1 >

  The recordset definition is shown below

  

  The result of the test success page is shown below, as you can see the name of the volunteers is not displayed immediately after the "Thank you" message, but the session variable containing the correct primary key (41) is displayed correctly.

  

  Someone has an idea what I am doing wrong?

  Thank you

  Tony

  Where did you put session_start()? It should be before the variable is accessible. This is obviously before the line that displays the value in your page, but that's before the SQL query is generated?

  Also, have you checked in phpMyAdmin to see if volunteernumber 41A all values in the database?

• What is the correct syntax for the use of a variable in an ad-hoc query?

  Hi all
  
  I'm a casual user of the DB and right now need to update the records about 1000 + so that a certain column gets a unique value.
  
  So I thought I'd use a variable for this.
  
  Then, I built this type of SQL statement for only a small subset of records:
  ----------
  variable number recNumber;
  exec: recNumber: = 1;
  UPDATE TABLE_TO_BE_UPD
  SET COL_TO_BE_UPD = COL_TO_BE_UPD + recNumber
  WHERE COL_TO_BE_UPD IN ('VAL_A', 'VAL_B');
  ----------
  
  I get invalid SQL statement error when you try to run above (except for the guest who asks for a value I want to omit).
  
  In any case, I also tried this one:
  ----------
  CREATE SEQUENCE seqCounter;
  UPDATE TABLE_TO_BE_UPD
  SET COL_TO_BE_UPD = COL_TO_BE_UPD + seqCounter.NEXTVAL
  WHERE COL_TO_BE_UPD IN ('VAL_A', 'VAL_B');
  ----------
  
  Of it, I got the error ORA-01722: invalid number... I guess it's because seqCounter is of type number and the COL_TO_BE_UPD is of type character... (?)
  
  Then I want to ask is what is the correct way to define and use a counter variable type to add a number at the end of a string?
  
  Also another question I would ask is that are variables that are used in queries ad hoc, also called "bind variables"?
  
  Thank you muchly

  If you want to add a unique number to a column, then it would be:

  UPDATE TABLE_TO_BE_UPD
  SET COL_TO_BE_UPD = COL_TO_BE_UPD ||to_char(rownum)
  WHERE COL_TO_BE_UPD IN ('VAL_A','VAL_B');
  

• How to send different value of variable presentation in URL GO?

  Hello
  I use GO URL to send presentation Variable (d_pv) to filter the other report on column 'day '...

  It works very well. But my goal is to filter the report by using the eve of the value of d_pv (for example. If the value of d_pv is ' 2010-04-27', I need to filter the others using report "(2010-04-26')"
  
  I couldn't find to spend one day back value of presentation using variables go url.
  
  Help, please...
  
  Published by: bob123 on April 28, 2010 10:15

  I would say use TIMESTAMPADD(SQL_TSI_DAY,...,1) and use spend your variable in this column.

  When you spend the day report 28/04/2010 + 1 column target, it will display the 27/04/2010 data.

• How can I use the Session variable in the repeat region

  I have a session variable assigned to the #(numérotation automatique dans access db) of the posts ID. The variable is set to the recordset object that is displayed first (sort by message ID descending). I would like to find a way to make the variable to assign to all records, if the variable is passed to the delete page. If I use a URL parameter to send the message ID, then someone could change the number in a browser and delete messages not intended for the user.
  If you want to see the example in action goto link at the bottom of the message. Save it and reply links are URL parameters response uses the variable MM_Username to enter the name of the sender for a URL parameter is OK, but click on save and then change the value of msdID in the browser for a different number and you can record and display another message not intended for your login id. The link delete uses a session variable that I posted in the Recordset as the auto access number msdID and the good msdID # do not are they assigned.
  What to hide the URL parameters, it would be simple, but how can I do?
  Thank you

• How to use a substitution variable in a rule of load?

  I need to use a substitution variable in a rule of load in a column, I will receive a parameter to correct the month and year of the values in the loading data, could someone tell me if this is possible. I put an expression '& Yearproc' in the value column, but it does not work.

  If you are a member of the WORLD (or even if not, you can register for free associate membership) you can download the presentation from Glenn since 2009 Kaleidoscope "little used Essbase features (such as data mining and triggers) ' - there is a section to this presentation on the substitution variables - it does a great job showing how it works.

  Go to: www.odtug.com, and then Tech, then Essbase/Hyperion resources and search for Schwartzberg. It is currently the ninth presentation on the list - I think that this change based on the popularity of downloads.

• How to store the values of variable level OBIEE presentation in DB

  Hi all!
  
  We have a command prompt of dashboard which is set up to store values in variables of presentation (period start and period end dates). Is there a way to store values selected from a database? for further processing?
  that is, I need to pass the variable level (report parameters) presentation to complex calculations to a PL/SQL function.
  Also my requirement might be solved if I can get access to the selected values of logical column in the tab 'Business Model and mapping' definition in the BI administrator.
  that is, I'll be able to define the logical column using VALUEOF (NQ_SESSION. < nom_var >)
  
  Kind regards

  Hello.

  1 do SQL PL/function (in the database) which has an input parameters, which number depends on number of guests and in it you'll insert these parameters into a table.

  2. your report in column expression answers call this function that will do insert, the code would be like:
  EVALUATE ("YOUR_FUNCTION (1%, 2%, 3%, 4%) (' as varchar (20), @{p_1}, @{p_2}, @{p_3}, @{p_4})

  3. Note that the function returns something and be careful on data types inside EVALUATE it.

  4. notes that, in the case where some messages are not selected (all or nothing) you recognize this case as:

  -case when LENGTH('@{pv_var}') > 0 then ' @{pv_var}' end else' all '.

  or like this:

  -case when LENGTH('@{pv_var}') is null then 'all choice"other" @{pv_var}' end; "
