  Actually looking at your results once again, that don't necessarily look as a problem of sorting.

  What is your version of Oracle?

  Can you explain why these lines are your expected results? For example if I have run the following query I see these results:

  SQL> SELECT  DA.ANAME
    2  ,       DA.DB_ID
    3  ,       DA.DC_ID
    4  ,       DB.ABBB
    5  ,       DC.ACCC
    6  FROM    DA
    7  JOIN    DB      ON DA.DB_ID = DB.DB_ID
    8  JOIN    DC      ON DC.DC_ID = DA.DC_ID
    9  ORDER BY 1, 2, 3, 4, 5
   10  /
  
  ANAME                     DB_ID                DC_ID ABBB       ACCC
  ---------- -------------------- -------------------- ---------- ----------
  Apples                        1                  100 B1test     C1test
  Apples                        1                  100 B1test     C2test
  Apples                        1                  100 B1test     C3test
  Apples                        1                  100 B2test     C1test
  Apples                        1                  100 B2test     C2test
  Apples                        1                  100 B2test     C3test
  

  Yet in your results, you have your lines collapsed as B1TEST and C1TEST are in the SAME ROW, but B2TEST is not in the same line as C1TEST or C3TEST. Why?

  Is that what you are looking for?

• A statement UPDATE changes the line if the update changes the column even value?

  HI -.

  I have a main classification and the corresponding audit table. I have a trigger. I created using the suggestion:http://www.runningoracle.com/product_info.php?products_id=211

  Now the problem that I am facing is that: if I run the same query (same value) update on the main table for n times (with the same data)... my audit table is updated with a new record every time. He is not able to determine that the value is the same.

  My goal is to load the audit table data if the value in a cell in the main table is really have changed.

  A statement UPDATE changes the line if the update changes the column even value?

  Best regards

  I have a main Table and the corresponding Audit Table. I have a trigger. I created using the suggestion:http://www.runningoracle.com/product_info.php?products_id=211

  Why?

  You try to resolve what made you what are the PROBLEM that select as the solution?

  Now the problem that I am facing is that: if I run the same query (same value) update on the main table for n times (with the same data)... my audit table is updated with a new record every time.

  Yes - it is EXACTLY what you say that you wanted to do and EXACTLY what the code does in this article.

  He is not able to determine that the value is the same.

  I think you mean that the code does NOT check if the value is the same. You can certainly change the code to do this check. But I have a question to start with your need for such a solution.

  My goal is to load the audit table data if the value in a cell in the main table is really have changed.

  OK - then modify the code to check EACH COLUMN and compare its NEW value to the OLD value and insert only the table of audit if SOME (or columns you care specifically) have changed.

  A statement UPDATE changes the line if the update changes the column even value?

  It depends on what you mean by 'change the line '. Of course to update a column with the SAME value does not change the resulting data value.

  But the physical structure of the line, the location of the pieces of line and information in the header block (YVERT, etc.) will change. And, as others have said Oracle doesn't know and doesn't care, so if the new value of a column is the same as the old value will create redo, undo and the rest.

  Start over and tell us what PROBLEM you're trying to solve. Then we can help you find the best way to solve it.

• I need to force the width of the columns to values that are smaller than the minimum preset (1 058 mm) indesign.

  Jongware provided two ideas to force the table rows and columns in the heights and widths smaller than the Indesign predefined 1.058 mm.

  For lines: app.selection [0] .properties = {autoGrow:false, height: "0.5 mm"};

  And for columns he sugested: app.selection [0] .width = "0.5 mm;

  The problem is that, while the code for lines works perfectly, for the columns return a error "Unit expected, but received 0.5 mm" I'm under Indesign cs6. Someone has ideas to help fixing such script, or maybe a different approach? Thank you!

  
  

  
  

  HM, other than the use of InDesign CS5.5 or underneath with scripts?
  Or export IDMS, open and edit (by script of course, it is just a plain text file in disguise), place IDMS and replace the table?

• ALTER TABLE with the column NULL time consuming

  Hello

  I have a table with nearly 2 million documents (about 10 GB size table) when I perform the following change statement its run fast

  ALTER TABLE tbl_1 ADD (DEFAULT col_4 NUMBER 100 NOT NULL);

  but when I do not give the NOT NULL in the alter its taking a long time to complete this i.e tbl_1 of ALTER TABLE ADD (NUMBER col_4 by DEFAULT 100); once I do the column as NOT NULL.

  Can someone explain why is it happening like that regarding the execution point.

  Thanks in advance.

  I can reproduce the effect in 11.2.0.1 - but not in 12.1.0.1.

  drop table tbl_1;

  create table tbl_1

  as

  Select rownum id

  , lpad ('* ', 50,' *') padding

  of the double

  connect by level<=>

  ALTER TABLE tbl_1 ADD (NUMBER col_4 by DEFAULT 100);

  --> slow in 11.2.0.1; fast 12.1.0.1

  ALTER TABLE tbl_1 ADD (DEFAULT col_4 NUMBER 100 NOT NULL);

  --> Quick 11.2.0.1 and 12.1.0.1

  A SQL trace for two operations (11g) shows that the altar slow (without the constraint explicit non-null) made explicit (and tedious) update of any row in the table:

  Update 'TBL_1"set"COL_4"= 100

  call the query of disc elapsed to cpu count current lines

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

  Parse        1      0.00       0.02          0          1          0           0

  Run 1 11,63 33.56 8336 1016125 2053531 1000000

  Fetch        0      0.00       0.00          0          0          0           0

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

  Total 2 11,63 33,58 8336 1016126 2053531 1000000

  The other trace file does not contain the explicit Update. I guess in the optimized case that oracle stores somewhere that col_4 has the value 100 and updates only the line of the block after completing DML operations. But that's just a guess.

• Error trying to filter the column named 'value' in the tab data

  Is there a way I can filter this column? I tried quotes around column name, 'value' = 60, but that did not help.

  1	Oman	Rugby Union	63180	Juv
  1	Oman	Rugby Union	63180	Teacher
  1	Oman	Rugby Union	63180	Juv

  the request requires the output as follows:

  ID	Country	Hobby	Internal_ID	CAT
  1	Oman	Rugby Union	63180	7

  because cat = 'juv' (5) is less cat =' teacher (7).

  all columns are not null and the primary key of the new_table is ID + hobby

  The script displays the following output:

  01400 00000 - 'impossible to insert NULL into (%s)' because does not recognize the function max.

  Thanks in advance.

  Actually there are values not in the range of cat. There is an error in the old data table.

• Returns the null value in HasMap.get ().

  Hi all.
  Just read the docs of java on hashmap and was interested in this topic the get() method:
  
  A NULL return value does not necessarily mean that the map contains no mapping for the key; It is also possible that the map explicitly maps the key null. The containsKey operation may be used to distinguish these two cases.
  
  I took in a case, which has been talked about: If the map allow nulls, returned by get() null will be just one key of the pair-> null value. But the second case is not clear to me. Please, show me an example for the latter case, when get() can returned null.

  There is no second case. There is a single case, if you put a null value in a map, get() will return null. And because of that, if you need to know if a certain key is in the containsKey() worksheet should be used instead of the get() method.

  Player_ID   Player_Name  Team_Name  Points Sequence
  99999       John Smith    Bulls              50         1
  99999       John Smith    Pistons          14         2
  
  
  What i want in the output
  Result B
  
  Player_ID Player_Name Team_Name  Points
  99999     John Smith      Bulls           64 (50 for Bulls)

  Here are my main request...
  

  select player_id, player_name, team_name, points
  from
          (
            SELECT player_id, player_name, team_name, sum(points) sum_points
            FROM stats_data
            WHERE season_id = 2008
            AND points > 0
            GROUP BY player_id, player_name, team_name
            ) t
  ORDER BY sum_points DESC, last_name;

  Current query gives me the result of the result of A
  
  (1) not entirely sure how, to combine the player_id basic data
  2) once I found 1, I'm sure that by adding the ("sum_points" for "team_name") to the output can be done with a case statement, I think?

  Hello

  Thank you.

  Let me make sure I understand: If a player on two or more teams, the one with the largest value of the sequence appears in the column team_name. Others will be displayed, in the order of sequence, in the points column.

  This done:

  The information listed in points (e.g. '(16 pour les TAUREAUX, 4 pour les PISTONS) ') requires the aggregation of the chain.
  [AskTom.oracle.com | http://asktom.oracle.com/pls/asktom/f?p=100: 11:0:P11_QUESTION_ID:2196162600402] shows several ways to do so.
  I used the first option on this page, the function defined by the user STRAGG, that you can copy from this page.

  You can have a similar function, the WM_CONCAT (property WMSYS), already installed.
  WM_CONCAT is not documented, so you can't use it in your Production applications.
