• Updated if the value of the form is empty?

  Is it possible to set a value of constant only if the value of this field is empty? My goal is to put a value down to net new contacts when the original lead source value is empty (trying to understand why this always happens).

  Thank you.

  Yes, you can add a hidden form field with a static value and using "Update Contacts - with form" stage computer, map the field to lead the original source with a Type of update if empty value "Update".

• I am defining a recordset and he asked me a test value for the variable in form, anyone can tell me what variables would look like?

  

  In your illustration, he indicates that there should be a form variable which passes the value to the query. For example, if there is an input field

  Then, when the form is submitted, it will pass the value to the query.

  When you test the query in Dreamweaver, this value is unknown, where the question. Simply a response with a value and everything's fine.

• Insert a NULL value when the field is empty

  Oracle 11 g 2
  
  Hi all
  
  This is probably a very simple question.
  
  Here's what's happening.
  
  I have a table:
  

  SQL> select * from mytable;
  
      MYCODE MYNAME          MYSAL
  ---------- ---------- ----------
        3456 Chris            8000
        9878 Bill
        6574 John             6500

  And I am running the following query:
  

  SQL> select 'insert into emp (empno, ename, sal) values (' ||mycode||', '||''''||myname||''''||', '||mysal||');'
  from mytable;

  gives me the following output:
  

  insert into emp (empno, ename, sal) values (3456, 'Chris', 8000);
  insert into emp (empno, ename, sal) values (9878, 'Bill', );
  insert into emp (empno, ename, sal) values (6574, 'John', 6500);

  If you notice, the second row has a sal as empty field. I want that he be null for what I can run this query to INSERT specific without having to manually enter the word "NULL" inside
  
  I think I need some kind of clause if-then here.
  
  If sal is NULL
  then the value NULL?

  Exactly!

  This condition IF-THEN-ELSE happening so often that they have designed a function for this.
  Instead of my_sal, use this expression:

  NVL ( TO_CHAR (mysal)
      , 'NULL'
      )
  

  It is:

  select 'insert into emp (empno, ename, sal) values ('      || mycode
                                                        ||    ', ''' || myname || ''''
                               ||       ', '      || NVL ( TO_CHAR (mysal)
                                                       , 'NULL'
                                          )

• Lag() ignore null values performance

  Hello

  I have looked around, but didn't find everybody talks about performance problems specifically with the use of 'IGNORE NULLS' inside of an analytic function of LAG() in a view online.

  This is a cut from the version of my sql, isolated to the question under discussion.

  select * from (
    SELECT /* use_nl (j,gjt,jt) */
       jt.id
      ,COALESCE
        (lag(jt.my_column ignore nulls /* this is the nasty critter */
          ) over (order by jt.order_seq)
        ,0
        )+1 AS start_days
      ,coalesce
        (jt.my_column
        ,last_value(jt.my_column ignore nulls
          ) over (order by jt.order_seq desc)
        ) AS end_days
    FROM  a,bunch,of,tables
    WHERE ...
    ) jt 
  where jt.id = '123456'
  

  If I remove ignores NULL values in the offset, there is no performance problem.

  Last_value() is not affected.

  If I do not use a view inline then performance is very good, although it is no different to explain the plan.

  select ..
  from ...
  where ...
  and id = '123456'
  

  Has anyone come across something like this, or have any suggestions?

  Happy to try to build a test scenario if it contributes to the discussion, but I thought I would just ask the question first.

  Scott,

  He would not have anything to do with your real problem, since you say that you get different performances during the removal of the IGNORE NULLS clause, but I doubt that you get exactly the same execution plan when online display is deleted these two queries are typically semantically the same.

  If you use the inline view, Oracle cannot push the filter on the ID in the view if the analytical functions partitions not by this ID, because the result will not be the same for the steps: with the online mode, the data is transformed without filtering for the evaluation of the expressions of the LAG etc, and then the filter is applied.

  If you remove the inline view and filter directly, it has a quite different meaning because now the data will be filtered first and then the analytical functions apply to the filtered result set.

  So the case of inline view maybe has to deal with a completely different volume (larger) identical to the variant of view data not online according to the selectivity of the filter - which could explain that the clause "IGNORE NULLS" made a significant difference in performance on this larger volume of data to deal with, but not necessarily.

• Ignore the condition AVERAGEIF referenced cell is empty?

  I'm trying to run an AVERAGEIF function based on up to 3 sets of test values whose conditions are determined by the entries in cells referenced in the formula.

  Here is a picture of the table:

  

  Seminar, day and hour are the columns from the drop-down list. Registered average and average archived have AVERAGEIF formulas that use the data in the table another as test values that resolves as true when they correspond to data in the corresponding cells of the seminar, day and hour [example: IFERROR (AVERAGEIF (seminar, Schedule::Registered, $Topic, $A2, $Days, $B2, hourly seminars: $B, $C2),' ')]. This set works fine if I have all three of the cells in the columns of seminar, day and time information, but I would like to also see average which which do not take into account (i.e., what are the averages for what seminar is offered Monday, regardless of what time?). Is it possible to get these formulas to ignore the conditions that are left in white?

  Thank you!

  AVERAGEIF accept them * and? wildcard characters.  You could try to enter * in the Time column and see if your formula returns desired results.  Without seeing the data format in your time table of the seminars, however, it is difficult to know if you need to make other adjustments to make it work.

  For example, you use Date & time format of data?  If so, numbers actually stores a date and time, even if you have a cell that is formatted to display only the time. This can give results, that you are not pregnant if you do not have two cells showing that same time can be interpreted by the numbers as being different, because the part of associated of the date string date and hour is different.

• display of the output cursor empty with null values

  I have the below procedure of the State where he is shown the output to the client.

  The requirement now is if the select statement does not return a value any with the input given then output parameter should see NULL values instead of no line at all.

  
  One method is to get the number of the select query that is written in "open p_out for." And then write the condition as if count is 0 then null other show data.

  Could you please suggest me any other alternative to this.

  Create or replace procedure test (p_empno in number , p_out out sys_refcursor) is

  Hello

  Check the messageChoice LOV VO is based on any Look up. If the values of the messageChoice VO is based on quick glance upward means follow these steps:

  Run the following query and get the id of the application:

  Select application_id from fnd_lookup_types WHERE lookup_type = 'LOOKUP_NAME. '

  And then run the following code passing the id of the application:

  SELECT (SELECT application_short_name
  FA fnd_application
  WHERE fa.application_id = frt.application_id
  and frt.application_id = 20386) asks,
  FRT.responsibility_id, frt.responsibility_name
  OF apps.fnd_responsibility_tl frt.

  Then check what responsibility he is attached, then go to this responsibility--> research

  Otherwise move the developer of the Application--> research

  Ask your search with the name, then check the code and feel that look upwards.

  If you can change, modify the value do not know else disable the value ignores by unchecking the checkbox.

  Add a value more that even looking for him.

• Conditional compilation: "If the $$id cannot be set to a value, then the PLW-6003 warning message is reported.

  Hello

  So according to the documentation:

  Conditional Directives of Compilation using survey

  The directive of inquiry is used to check the compilation environment. The directive of inquiry is of the form:

  inquiry_directive ::= $$id

  A directive of inquiry can be preset as described in 'predefined help investigation with Conditional Compilation Directives' or be defined by the user. The following describes the order of the processing flow during conditional compilation is trying to solve a directive of inquiry:

  1. The id is used as a guideline for investigation in the form $$ id for the search key.
  2. Re-encoding algorithm is as follows: the string in the PLSQL_CCFLAGS initialization parameter is scanned from right to left, the search with id for a matching name (case sensitive); if it's recognized. The predefined survey guidelines are sought after; Done if found.
  3. Si le $$ id cannot be resolved to a value, then the PLW-6003 warning message is sent if the original text is not wrapped. The literal NULL is substituted as the value for undefined investigation guidelines. Note that if the PL/SQL code is wrapped, then the warning message is disabled so that the directive of inquiry not defined is not revealed.

  I take this means, if you $IF $$xxx.00 = $5 THEN... $END but have not set a $$xxx.00 with "alter session set plsql_ccflags" then you should expect an error.

  But I am unable to make this trigger, a warning, or an error, either by

  ALTER session set plsql_warnings = ' error: 06003. "

  or

  ALTER session set plsql_warnings = ' enable: all ';

  test configuration:

  SCOTT@ORCL> alter session set plsql_ccflags = '';
  Session altered.
  SCOTT@ORCL> alter session set plsql_warnings = 'enable:all', 'error:06003';
  Session altered.
  BEGIN
      $IF $$DEBUGON $THEN
          dbms_output.put_line('debug is on');
      $ELSIF NOT $$DEBUGON $THEN
          dbms_output.put_line('debug is NOT on');
      $ELSE
          dbms_output.put_line('debug is neither on nor off - DEBUGON IS NOT SET!');
      $END

  debug is neither on nor off - DEBUGON IS NOT SET!

  The compiler warnings do not seem to work for anonymous blocks, only for named objects:

• How to assign the text value when the data in the column is null or empty

  Hello guys
  
  I have a small question
  
  I have a column A that half of its value is empty, now the condition is that whenever the column is empty, assign "N/a" in the column... So I wrote a code which is:
  
  <? If: not (column A)? > column a = 'n/a' <? end if? >
  
  However, when I preview the RTF model, the data in the column still has not changed at all, many lines are still empty and did not show 'n/a '... The column is of type text
  
  Please advice

• Bug in the conditional for loop with an array empty

  There seems to be a bug in the loop with a conditional terminal.

  If an empty array is connected to an indexed table auto entry tunnel, a tunnel of output array has an element instead of zero.

  

  The constant matrix is left empty.

  High loop without the conditional Terminal produces an empty array.

  Conditional down with a terminal loop never true generates an array containing a single element

• How to read the size of the array, eliminating empty values

  I have an array of size 2 X 10. In the first column, the elements are 10 and in the second column, the elements are only 6. If I use the size of the array and the size of the second column of the index, the value given is 10 which is supposed to be 6. I noticed that it creates null or empty values in the column for the other four. How can I eliminate empty values, and only get the real sze of the column?

  The column in the index and use search 1 D table for an empty string.  The result should be the number of non-empty strings.  If the result is - 1, use the actual size of table.

• Textarea conditional display based on the value of the checkbox.

  Hi all

  I have a question regarding the conditional display of an article based on the value of the checkbox.

  I have a checkbox in a region, which is a STATIC LOV:; Y and the text box in the same region. Now I want to show this textarea only if the check box is selected. ??

  Please suggest how to achieve this.

  Thank you

  Hello

  I guess that you are 4.2 Apex as you haven't shared the same.

  • Create a dynamic Action on change of box which should present the value of the checkbox and update the TextArea element.
  • Then continue as conditional Textarea with checkbox value.
