  Hi all
  I use a BPM opensource to store variables in a Workflow process. Variables are stored in an Oracle 10 database and can be retrieved using the native Api of BPM (Java) or by using Sql. For performance reasons, I use simple SQL to collect a list filtered workflow variables.
  
  Here is a simplified version of the BPM_INSTANCE Table:
  
  [NAME] [VALUE] [PROCESS_INSTANCE]
  =====================================
  AREA IN ADDITION TO 1 125
  ACME CUSTOMER 125
  ID_WO 500 125
  
  2 200 FIELD
  200 TEST CLIENT
  ID_WO 501 200
  
  1 225 FIELD
  CUSTOMER MODEL 225
  ID_WO 502 225
  
  Each PROCESS_INSTANCE has a set of variables that have a NAME and a VALUE.
  
  My need is to collect the list of all (500,501,502) ID_WO, PROCESS_INSTANCE belongs to a DOMAIN (ex. 1) and one client (e.g. ACME)
  
  I started coding the SQL:
  
  Select VALUE from BPM_INSTANCE where NAME = 'ID_WO' and PROCESS_INSTANCE in
  (select PROCESS_INSTANCE from BPM_INSTANCE, whose NAME = "CUSTOMER" and VALUE = "ACME"
  )
  However, I am not able to meet several conditions (for example I need also the PROCESS_INSTANCE also contains an AREA = 1).
  Can someone help me?
  Thank you
  Frank

  Hello

  Would this work:

  with data as (
   select 'AREA' as name, '1' as value, '125' as pi from dual union all
   select 'CLIENT' , 'ACME', '125' from dual union all
   select 'ID_WO', '500', '125' from dual union all
   select 'AREA', '2', '200' from dual union all
   select 'CLIENT', 'TEST', '200' from dual union all
   select 'ID_WO', '501', '200' from dual union all
   select 'AREA', '1', '225' from dual union all
   select 'CLIENT', 'DUMMY', '225' from dual union all
   select 'ID_WO', '502', '225' from dual)
  select o.value, i.value, ii.value from data o
   inner join data i on ( o.pi = i.pi )
   inner join data ii on ( o.pi = ii.pi ) where o.name = 'ID_WO' and i.name = 'AREA' and ii.name = 'CLIENT';

• Is it possible to delete a plot with the help of the mouse select the chart control?

  For example, when I use the plot to draw thousands of lines on the chart control, I want to delete some of them, but there are thousands of generated plotHandle.

  How can I get the plotHandle of the specific line on the chart control with the help of the mouse to select the option?

  If I save the information from the lines, such as the plotHandle and the coordinates on a table or list, etc, I compare information lines for the plotHandle of the specific line.
  Is it all a user-friendly way to remove a track selection on the chart control?

  I can't give you a reasonable way to solve this problem, since as you have already noted plot do not snappable plots.

  A possible warkaround would be to replace the plot of individual instructions with a PlotXY matching with 2 bays 2 points each, which correspond to the x 1, x 2, y1, y2 parameters to plot. PlotXY plots are snappable, so you can enable this procedure select the plot and remove it.

• Need help with the curve of a group of objects

  Salvation Group;

  This is my first post in this group. I'm quite new to Adobe Illustrator CS5, and I had to start using it to provide the type of file to a printer for Sublimation in the USA. They use CS5, and all colors are limited to the Pantone Solid Coated for their printing system. I'm swimsuit fabric printing.

  However, my question is probably very basic. It is also frustrating, because I have already successfully did this that I ask, just do not remember how I did it.

  

  In my image, the upper rectangle has curved shape finished (bottom). I've done this before, with in fact several objects together. They all have the curve with the rectangle.

  I tried to do it again, using all kinds of transformation tools (shear), the tools of the effect and everything I could find, but nothing has worked. I thought that maybe to shear would work if I could fix in the middle of the rectangle and shear on both sides of the rectangle to the top, but it does not work. I think I'll start to take notes when I find something that works!

  How this simple curves of single object or group of objects? It can be done, I know!

  Thank you, Tom.

• Help returns the array of query results

  Hi all... Pretty new to this so please forgive my ignorance. Running Oracle 11 g, trying to return results as in the example I give below. I don't know how the Sport field will have unique values, and I don't know how many unique values the year field is seen in the data. Does anyone have recommendations/suggestions?
  
  The structure of the table is:
  Year of sport
  Baseball 10-11
  Football 10-11
  Football 11-12
  Football 11-12
  Football 11-12
  Baseball 11-12
  
  The result should be sports in each year and should be grouped by year but shown as columns so:
  (GROUP OF the year)
  1, baseball 1, Football
  2, 1, Football Soccer 1, Baseball
  
  
  I hope that makes sense. Thanks for any help!
  ... Kaelon

  Does anyone have recommendations/suggestions?

• Help at the waterfall "select choice".

  Hello
  I tried to create a JSF page with 2 commands 'Select one choice' A and B. The contents of the control B depend on the selection made on the control. So far what I have is control B displays the contents of the related data of the first element on the control, but if I change the selection on the control B does not change its content.
  
  What are the steps to create a pair controls 'Select' cascading in a JSF page?
  
  Command has must indicate the attribute X table X.2
  Control B to display the attribute table Y.2 Y
  Attribute X 1 is a primary key
  Y.3 attribute is a foreign key (of the X.1 attribute)
  Y.1 attribute is a primary key
  
  Can I use read only views?
  
  Thank you.

  the steps are

  -define autosubmit = true on selectOneChoice 1
  -Have a ValueChangeListener who gets the selected value and who uses it to set the query for the dependent list condition
  -use AdfFaces.getCurrentInstance () .addPartialTarget () to update the first list

• Help on the game of query results

  Hi gurus,

  Have this survey for my requirement of dataset sql.

  Sample, it's that I have to pick up the nonfunctional currency transactions.

  Lets say for a given month, data that are present are for CurrencyA and CurrencyB for a particular account.

  Account1 has a transaction does not work CurrencyA and CurrenyB then Account2 has only transaction to CurrencyB.

  My current query result is that the 3 first lines, what I need is the 4th should also appear and be included.

  CurrencyA - amount - account1

  CurrencyB - amount - account1

  CurrencyB - amount - Account2

  CurrencyA - < '0' / or null >-Account2

  I think that my request is based on the currency < x > I have, so it should be for each account, he has all the lines for each currency.

  If please notify and let me know your thoughts.

  Hello

  It looks like you want an outer join partitioned.

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired 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).

• Help with the query to return the results of the group in the table?

  Hello
  Im a total noob, so please be nice...!
  
  I'm looking around a table contains a column of WORD and a WORD_TYPE_ID column.
  Words can have the same type_id.
  
  What I'm trying to do is to write a query that will return the longest word for each word_type_id.
  I tried for hours to get it and everything seems to get is two error messages or just the longest word in the whole WORD column.
  
  Is the furthest I can get before things break down...
  
  Select Word
  table
  where
  Length (Word) =
  (
  Select
  Max (length (Word))
  table
  )
  
  Any help on this or if I could be pointed in the right direction it would be greatly appreciated.
  
  Thank you

  Hello

  Welcome to the forum!

  Here's one way:

  SELECT    word_type_id
  ,       MIN (word) KEEP (DENSE_RANK LAST ORDDER BY LENGTH (word))     AS longest_word
  FROM       table_x
  GROUP BY  word_type_id;
  

  If there be a tie in some word_type_id (i.e. 2 or more words have exactly the same length, which is the longest in this group) the expression above will return the first one alphabetically. (This is what means here MIN.)

  Published by: Frank Kulash, 11 August 2009 13:56

  You almost had it.
  As you have noticed, you get the longest line across the table. This is because your subquery was watching the entire table.
  If you to correlate the subquery to the row in the main table, as shown below, you can get the longest word in each group:

  select  word
  from     table     m                              -- m for main
  where      length (word) = (
                              select  max (length(word))
                 from     table
                 where     word_type_id  = m.word_type_id     -- New
                 );
  

• Need help with the use of GROUP BY in a select statement UNION

  I am writing a query that allows to combine a legacy system that interfaces it is trial balance in the Oracle of R12 GL.  It was only meant to continue for a month or two, but it is likely to continue for 6 months. Please Auditors Auditors, to provide proof that the system is in balance with Oracle GL.  By my verification requirements, I need to make a full reconciliation from the month of conversion (life in the amount of date), then PTD for each month. 

  The legacy account is placed in attribute1 on the lines of the journals. Uses of the old system balancing segments that are also used on the platform in Oracle for this division, i.e., Procure-to-Pay has been cut over Oracle, but not everything yet.  So, I can't count on the GL_BALANCES table for the info, I get from the JE_LINES.

  My problem is not the only request for the month.  But when I try to combine the queries with a Union, to aggregation of each measurement period in its own column, the group is necessary after each selected instruction rather than allowing me to put at the end of the UNION.  (When I put the group by at the end of the UNION, I have the 'not one group' function)

  So I get duplicate for each month of discrete measure accounts. When I duplicate in my Oracle database accounts, I can't count on the VLOOKUP function in excel to exactly match an account of inheritance.  I know there are more sophisticated ways to provide this output, but I'm hoping to get this info in a simple query.

  Thank you in advance for any advice you can provide

  Example of data output (the goal for me is to get the two rows to appear as one based on common points on the LEGACY_ACCOUNT and the ORACLE ACCOUNT

  The LEGACY ACCOUNT	ORACLE ACCOUNT	JUN_15	JUL_15	AUG_15	SEP_15	OCT_15	NOV_15	DEC_15

  ?

  I have the following requirement, the output should be:
  
  Number of ticket (sr_number)
  % of tickets inside the DL
  Number of tickets inside the DL
  Average cycle time (cycle time = closing date - date of creation)
  Total cycle time (cycle time = closing date - date of creation)
  Number of reallocations (sum)
  
  
  DL - (deadline) formula is, closed date < = target_date
  
  This should be displayed, grouped by year, then month, then the assignment group. The values must be in descending order (dates) is not sure that group in operation here.
  I am able to write the code base of the foregoing, but group from the year, month, and group assignment is pretty confusing to me.
  
  
  Can someone give me a voucher code...

  This may not give you exactly what you want, but if all goes well, it will give you something to work with:

  WITH tickets AS (
    SELECT TO_CHAR(created, 'YYYY') created_year,
           TO_CHAR(created, 'MM') created_month,
           assignment_group,
           COUNT(sr_number) ticket_count,
           AVG(closed - created) avg_cycle_time,
           SUM(closed - created) tot_cycle_time,
           COUNT(reassignment_count) reassign_count
     FROM dummy
     GROUP BY TO_CHAR(created, 'YYYY'),
              TO_CHAR(created, 'MM'),
              assignment_group
  ),
  dl_tickets AS (
    SELECT TO_CHAR(created, 'YYYY') created_year,
           TO_CHAR(created, 'MM') created_month,
           assignment_group,
           COUNT(sr_number) ticket_in_dl_count
      FROM dummy
      WHERE closed <= target_date
      GROUP BY TO_CHAR(created, 'YYYY'),
            TO_CHAR(created, 'MM'),
            assignment_group
  )
  SELECT t.created_year,
         t.created_month,
         t.assignment_group,
         t.ticket_count,
         NVL(dl.ticket_in_dl_count, 0) ticket_in_dl_count,
         NVL(dl.ticket_in_dl_count/t.ticket_count, 0) * 100 pct_ticket_in_dl_count,
         t.avg_cycle_time,
         t.tot_cycle_time,
         t.reassign_count
    FROM tickets t,
         dl_tickets dl
    WHERE t.created_year = dl.created_year (+)
    AND t.created_month = dl.created_month (+)
    ORDER BY created_year DESC, created_month DESC
