• Prevent the Insert with Error Message

  Hello
  
  I have a req where a user cannot insert two rows of the same kind.
  
  To achieve this I write a process to compare the line that is inserted with the existing lines.
  
  I don't know where and what to include in the code while once create button an error message pops up and the insertion of the line is not processed or the line is not processed.
  
  How to display an error message?
  How to prevent you insert this line?
  
  Please suggest.
  Thank you.

  If I add a row to a table and use all THE columns duplicate values, but the id column (which should be unique [system-generated]), I would still have some duplicate data in all the other columns, correct?

  If the OP wants to ensure without duplicating the data are entered, he would have the better to try and produce a checksum for all data entered in the line and determine if any other input line generates a corresponding checksum, if so, then an error message should / could be displayed showing the possibility of a double row of data...

• Parallel insert with noappend hint

  Hello

  I have a question about parallel to insert with the noappend indicator. Oracle Documentation says that:

  Append mode is the default for a parallel insert operation: data are always inserted in a new block, which is allocated to the table. Therefore, the APPEND is optional. You must use Add method to increase the speed of INSERT operations, but not when the use of space must be optimized. You can use NOAPPEND to void append mode.

  
  

  When I delete (all) and insert (parallel use noappend) and I see the number of blocks used by my table always increases. The blocks must not be reused due to remove it before insert?

  
  

  Version; Oracle Database 11g Enterprise Edition Release 11.2.0.4.0

  
  

  Here is the script I used:
  

  
  

  drop table all_objs;

  create the table all_objs in select * from object where rownum < 10000;

  Start

  DBMS_STATS.gather_table_stats (User, 'ALL_OBJS');

  end;

  Select the blocks of all_tables where table_name = 'ALL_OBJS ';

  ALTER session enable parallel dml.

  Start

  I'm in 1.5

  loop

  delete from all_objs;

  Insert / * + NOAPPEND PARALLEL (8 O) * /.

  in all_objs O

  Select * from object where rownum < 10000;

  end loop;

  end;

  commit;

  Start

  DBMS_STATS.gather_table_stats (User, 'ALL_OBJS');

  end;

  Select blocks of all_tables

  where table_name = 'ALL_OBJS ';

  Output:

  Deleted table.

  Table created.

  PL/SQL procedure successfully completed.

  BLOCKS

  ----------

  142

  1 selected line.

  Modified session.

  PL/SQL procedure successfully completed.

  Validation complete.

  PL/SQL procedure successfully completed.

  BLOCKS

  ----------

  634

  1 selected line.

  
  

  
  

  Why block increase of 142 to 634 even with the noappend trick?

  
  

  Thank you.
  

  Well, looks like the expected result:

  Repeated insertions PARALLELS - a lot of direct path writes, table size increases as the lines are added above the HWM, final size after ten iterations = 10 x original size

  NOAPPEND PARALLEL repeated inserts - no direct path did not write, size of the table increases do not significantly, lines inserted under the HWM

  The NOAPPEND PARALLEL insert clearly is re-use of space released by the deletion. However, I wonder why there is an overload of 3,000 blocks? It would be interesting to see how the overhead varies according to the degree of parallelism.

• BAD RESULTS WITH OUTER JOINS AND TABLES WITH A CHECK CONSTRAINT

  HII All,
  Could any such a me when we encounter this bug? Please help me with a simple example so that I can search for them in my PB.
  
  
  Bug:-8447623
  
  Bug / / Desc: BAD RESULTS WITH OUTER JOINS AND TABLES WITH a CHECK CONSTRAINT
  
  
  I ran the outer joins with check queries constraint 11G 11.1.0.7.0 and 10 g 2, but the result is the same. Need to know the scenario where I will face this bug of your experts and people who have already experienced this bug.

  Why do you not use the description of the bug test case in Metalink (we obviously can't post it here because it would violate the copyright of Metalink)? Your test case is not a candidate for the elimination of the join, so he did not have the bug.

  Have you really read the description of the bug in Metalink rather than just looking at the title of the bug? The bug itself is quite clear that a query plan that involves the elimination of the join is a necessary condition. The title of bug nothing will never tell the whole story.

  If you try to work through a few tens of thousands of bugs in 11.1.0.7, of which many are not published, trying to determine whether your application would be affected by the bug? Wouldn't be order of magnitude easier to upgrade the application to 11.1.0.7 in a test environment and test the application to see what, if anything, breaks? Understand that the vast majority of the problems that people experience during an upgrade are not the result of bugs - they are the result of changes in behaviour documented as changes in query plans. And among those who encounter bugs, a relatively large fraction of the new variety. Even if you have completed the Herculean task of verifying each bug on your code base, which would not significantly easier upgrade. In addition, at the time wherever you actually performed this analysis, Oracle reportedly released 3 or 4 new versions.

  And at this stage would be unwise to consider an upgrade to 11.2?

• Need help writing an update / insert with linked tables

  I am new to ColdFusion. I am learning to write querys and creates a small application to collect information from visitors to my web site. (It's also a good way for me to learn this language) I'm having a problem and it is not only the way to use an update / insert with related tables. I don't know if I'm still gather the appropriate variables to compare them to existing DB records until his execution is the update or insert some querys. Can someone help me, show me how can I update / insert related tables and maybe tell me if I create the varibales good to the compairison? This is my code, I commented out.

  <! - creating a variable to compare with the db table - >
  < cfset userIP = ('#CGI.) REMOTE_ADDR #') >

  I'm close on this? This throws any errors, but it is not no longer works. It is so obviously wrong. I get a cfdump the end of my query of compairison, but once it hits the stated case, it is lost.

  You must define the variable before you can use it.  You try to use it on line 1 of your model.

• Insert rows in double with difrent languages

  Hello everyone,
  I need your help to solve this query with the most efficient way.
  I have a table:

  Create Table "POSITION" (
  id  number,
  TEXT varchar2(50),
  Language Varchar2(1)
  );

  INSERT orders

  INSERT INTO POSITION 
  VALUES (1, 'Secretary', 'E');
  INSERT INTO POSITION 
  VALUES (1, 'Secrétaire', 'F');
  INSERT INTO POSITION 
  VALUES (1, 'Segretario', 'I');
  INSERT INTO POSITION 
  VALUES (1, 'Secretario', 'S');
  INSERT INTO POSITION 
  VALUES (2, 'Assistance', 'E');
  INSERT INTO POSITION 
  VALUES (2, 'Ayuda', 'S');

  As you have seen changes to text in different languages for the same identifier. for some reason, the data are complete in all languages (from the ID missing some English french and little Italian). I need to a query to insert the missing in my example above language Id number 2 French and Italian language is missing, then the application must copy the English instead of the folder but with language = 'F' and once more with language = 'I' and so on.
  In addition the query should look to copy the English if there are then French or Italian then when more than one language are.
  
  hope that I clarify for me. as I said, that this request should be performing also the data size is big.

  Hello

  Thanks for posting the CREATE TABLE and INSERT statements; THA is very useful.

  Here's a way to do what you want:

  MERGE INTO     position     dst
  USING     (
            WITH       all_language     AS
            (
                 SELECT  'E' AS language, 1 AS ord_num     FROM dual     UNION ALL
                 SELECT     'F',           2          FROM dual     UNION ALL
                 SELECT     'I',           3          FROM dual     UNION ALL
                 SELECT     'S',           4          FROM dual
            )
            SELECT     p.id
            ,     FIRST_VALUE (p.text IGNORE NULLS)
                      OVER ( PARTITION BY  p.id
                             ORDER BY      l.ord_num
                           )     AS top_text
            ,     l.language
            FROM           all_language     l
            LEFT OUTER JOIN  position     p     PARTITION BY (p.id)
                                     ON  l.language     = p.language
       )               src
  ON     (     src.id          = dst.id
       AND     src.language     = dst.language
       )
  WHEN NOT MATCHED THEN
  INSERT     (dst.id, dst.text,     dst.language)
  VALUES     (src.id, src.top_text, src.language)
  ;
  

  It might be just as effective to do an INSERT and not a MERGER.

  You probably already have a table such as all_language which indicates what are the languages, and in what order they should be used to get the missing values. If so, use this table where I used the subquery all_language above. If you do not have such a table, consider creating one; It might be useful for a number of reasons, including the validation of language when you INSERT or update the position.
  In this case, the alphabetic order of the codes 'E', 'F', 'I' and ' happens to be in the order you want, but it's wrong to programming build on this. If they change the order, or add another language, the code would require much larger changes.

  You might consider adding a new column, indicates that the word in the text really is a word in the given language, or has been copied from another language just to fill a void. I suggest another VARCHAR2 (1) column, called names, which will be equal to the language when the text is actually a word in that language.

  The interesting thing is that after cancellation of the table _e err$ I still have lines that generated errors (violations of constraint not null I produced).

  Is this a feature or a bug?

  It appears like the insertion in the error table is an autonomous transaction that gets committed automatically independent of the transaction containing the insert statement.

  Why wouldn't be so?

  The error table can be even a global temporary table with preserve rows on commit. And I think this can help because I wouldn't need to worry about truncate table prior to insertion and there is no problem if several sessions would use this table.

• Limit the records inserted with FUSION

  I created a procedure for updating a table date of termination when the user enters a date of term.  Username and ID (PK) comes from t_users and the endings are in t_terms with t_terms.user_id = t_users.id as key.  There are about 2,500 users and curently nothing in the picture of the word.

  This procedure lights are part of a dynamic of action when the page is sent on an Apex application:

  create or replace Procedure "TERM_UPDATE"

  ()p_user_id IN NUMBER

  p_term_eff_date IN DATE )

  is

  Start

  fusion en t_terms t

      using t_users u

      on (t.user_id=u.id)

  when matched then

  to update the value TERM_EFF_DATE=p_term_eff_date where useridentifier=p_user_id

  when not equal then

  integration ()user_id term_eff_date) values ()p_user_id p_term_eff_date)

  end ;

  I tried just the merge statement in SQL Workshop.  The result is an insertion of 2500 all records user to the table of endings each time that it fires.  If I run again, I get 5000 inserts.  If I understand this process, t.users_id = u.id must return nothing, triggering the insert without match.  Even when there is a match, I always get the insert.  What the hell is happening?

  The p_user_id and the p_term_eff_date are power from bind on page variables.  I put those to be bind variables when I tested the query.

  I'm under apex 4.2 on 11g.

  Thank you!

  Hello

  Thanks for posting the instructions CREATE TABLE.

  Don't forget to display instructions INSERT for you samples, a few calls to the procedure (with specific values for the arguments) and content of t_term after each call.

  What t_users role in this problem?  You get all the information to t_users; you already know the user_id to the time wherever you call the procedure.  I guess the only reason why you have to t_users to this problem is to guard against inserting a user_id not valid in t_term.  (The foreign key constraint would guard against that, too, but it would trigger an error.  You might find a little more elegant to just merge 0 line when an invalid user_id is passed to the procedure.)

  Here's a way to do it:

  create or replace procedure 'TERM_UPDATE '.

  (p_user_id in NUMBERS

  p_term_eff_date IN DATE

  )

  is

  Start

  merge into dst t_terms

  a_l'_aide_de)

  Select id as user_id

  of t_users

  where id = p_user_id

  )              src

  on (dst.user_id = src.user_id)

  When matched then

  update set TERM_EFF_DATE = p_term_eff_date

  where DECODE (TERM_EFF_DATE - if wanted

  p_term_eff_date, 1

  0

  ) = 0

  When not matched then

  Insert (dst.id, dst.user_id, dst.term_eff_date)

  values (term_id_seq. NEXTVAL, src.user_id, p_term_eff_date);

  end;

  /

  DISPLAY ERRORS

  Because t_terms.id is forced to be NON NULL, you must provide a value for the id before you can insert a new line in t_terms.  In the above procedure, I guess you have a sequence called term_id_seq for this purpose.

• &lt; Cfquery &gt; insert generates the double entry

  At the start of Thunderbird, it opens the mail entering the lower panel with one click. But after an hour or two that no longer works and I have to double-click to open the message that is sent in a new window.

  Looks like a bad add-on for me. Now restart the SHIFT key and see if the issue arises again.

• How to solve a major conflict of Firefox with the double LG Smart monitor control screen running.

  PC: Dell Dimension E510 with MS windows XP Professional, Version 2002, Service Pack 3

       Intel(R), Pentium (R) D CPU 2.8 GHz, 1.0 GB Ram.
  

  I have a new 23 "LG monitor (23EN43T). Software to manage LG displays on the screen is called double Smart Solution, which works very well except with Firefox! Firefox screen goes immediately to more than 100% of the space on the screen. I can't even leave Firefox without using Ctrl + Alt + Delete. Then, I uninstalled and reinstalled Firefox, but it does not solve the problem.

   To get around this problem I have to use Internet Explorer.
  

  Firefox may be restoring the last used window dimensions based on a non-plus-relevant monitor configuration. You can try to delete a settings file and see if Firefox detects better your installation at the next reboot.

  With Firefox closed, open your current folder of the (AKA Firefox profile) on Firefox settings. Paste this in the search box on the start menu or in the address bar of Windows Explorer:

  %APPDATA%\Mozilla\Firefox\Profiles
  

  If you find more than one folder, open the one that has been recently updated.

  Rename localstore.rdf to something like localstore.old (in case you want to recover it later)

  Restart Firefox. It is positioned more logically?

  In addition, you should be able to leave "blind" Firefox using these key combinations:

  • ALT + F4 (General combination 'close this window' on Windows)
  • ALT + F, then X (hotkey for File > Exit)
