  Hello

  If all the values needed to update a given line from table_x come from the same line of table_y (or in the same row of a result set of a query on a number any of tables), then you can do something like this:

  UPDATE  table_x  x
  SET     (col1, col2, col3, ...)
  =     (
           SELECT  NVL (y.col1, x.col1)
           ,         NVL (y.col2, x.col2)
           ,         NVL (y.col3, x.col3)
           FROM    table_y  y
           WHERE   x.pkey   = y.expr
           AND         ...
       )
  WHERE   ...
  ;
  

  If the WHERE clause is based on the same line of table_y, then it will be probably easier and more efficient to use the MERGER instead of UPDATE.

  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.
  In the case of a DML (UPDATE), for example, the sample data should show what looks like the tables before the DML, and the results will be the content of the or the tables changed after the DML.
  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).

• Update statement with joins

  Hello
  I tried to update the 50 rows in a table using joins
  
  But the error

  ORA-01732 data manipulation operation not legal on this view

  But the table I worked is not a view

  You cannot update a subquery. To update the table tran instead.

  To select the 50 lines you want, your logic in the WHERE clause of the nesting.

  UPDATE tran

  In practical terms, Alex is right. Sometimes it matter what table is selected first, but does the CBO generally a very good job of deciding what you need to select the first (assuming that your statistics are up to date) but this is the situation you are trying to avoid as much as possible.

  If you specify a table main command tables in the clause is not reliable and should be used - but think before using advice and don't do that when necessary.

  Which table to select depends firstly on the join method in the execution plan. Nested loops joins perform better by selecting in the smaller table first, make a loop on the largest table. Joins the smaller set hash table in memory first, and then go through the larger table, perform searches in memory. He can't make any difference, what table is read using first the merger joins and sort.

  Back to your original question. Using the cost-based optimizer, both queries will probably roll the same because newer versions of Oracle (9i, 10g) often transform queries for efficiency before the execution anyway. According to what do you or do not request should probably run a nested loop or hash join. With a small set of data creaing index and using a search of nested loops will probably be faster to avoid full table scans. the '%' in the LIKE clause leader would ignore an index on the ISO_NAME column in any case if a main column may be used in a composite index. All this is based on the approximation using the information provided; Tuning questions should always be tested to unexpected developments.

• Query with join optimization research and details of the extra column

  I have the following SQL used for a report that comes out some stats (with some research of names). There is a good chance it is probably possible to optimize with better SQL, but I also hope to add an additional column, which I'm not sure.

  I want the extra column at one percent, which is total % of the lines of the value of the units, for the combination of category/group.

  Oracle SQL is v11.2.0

  Here's the SQL code, as it is currently:

  select a.date_adjusted, 
         a.task_name,
         sum(case when a.units_adjusted is not null then a.units_adjusted else a.units_original end) Units, 
         b.group_name, 
         b.category_name
  from   actuals_intake a
  left join
  -- lookups to obtain group and category names from their ID's in the groupings table
         (select c.task_id, 
                 d.group_name, 
                 e.category_name, 
                 c.business_unit_id
          from   task_groupings c,
                 task_groups d,
                 task_categories e
          where  c.group_id = d.id
          and    c.business_unit_id = d.business_unit_id
          and    c.category_id = e.id
          and    c.business_unit_id = e.business_unit_id
  ) b
  on    a.task_id = b.task_id
  and   a.business_unit_id = b.business_unit_id
  where a.business_unit_id = :P10_SELECT_BUSINESS_UNIT
  and   a.date_adjusted between to_date(:P10_DATE_START, 'dd-mon-yyyy') and to_date(:P10_DATE_END, 'dd-mon-yyyy')
  group by a.date_adjusted, a.task_name, b.group_name, b.category_name
  order by a.date_adjusted, b.category_name, b.group_name
   

  This will set up the tables and data:

  CREATE TABLE ACTUALS_INTAKE (

  INTO TASK_GROUPINGS (TASK_ID, GROUP_ID, CATEGORY_ID, BUSINESS_UNIT_ID)
  VALUES (6, 3, 3, 10)
  select 1 from dual;
   

  Results will look like this. The last column is what I want the extra column to look like:

  Date_Adjusted	TaskName	Units of	GroupName	Category_Name	Units %
  15/03/2014	A task	200	Group 1	Category A	87
  15/03/2014	Task 2	30	Group 1	Category A	13
  15/03/2014	Task 3	650	Group two	Category A	100
  15/03/2014	Task 5	15	Group three	Category B	27
  15/03/2014	Task 6	40	Group three	Category B	73
  15/03/2014	Task 4	400	Group two	Category B	100

  Hope all that makes sense... Anyone able to help me do this effectively?

  Hello

  Use the analytical RATIO_TO_REPORT function to calculate the % of units column.

  If you're serious about performance, please refer to the Forum:

  Re: 3. how to improve the performance of my query? / My query is slow.

  Do you really need an outer join?  Inner joins are faster.  With the given sample data, they produce the same results.

  COALESCE may be a little faster than the CASE.

  Try this:

  WITH got_units AS

  (

  SELECT a.date_adjusted,

  a.Task_Name,

  sum of units (COALESCE (a.units_adjusted, a.units_original));

  b.group_name,

  b.category_name

  of actuals_intake one

  the left join - or just JOINED

  -research for the group names and category of their ID in the table of groupings

  (select c.task_id,

  d.group_name,

  e.category_name,

  c.business_unit_id

  of task_groupings c,.

  task_groups d,

  e task_categories

  where d.id = c.group_id

  and c.business_unit_id = d.business_unit_id

  and c.category_id = e.id

  and c.business_unit_id = e.business_unit_id

  ) b

  On a.task_id = b.task_id

  and a.business_unit_id = b.business_unit_id

  -where a.business_unit_id =: P10_SELECT_BUSINESS_UNIT - if necessary

  - and a.date_adjusted between to_date (: P10_DATE_START, 'Mon-dd-yyyy') and to_date (: P10_DATE_END, ' mon-dd-yyyy "")

  Group of a.date_adjusted, a.task_name, b.group_name, b.category_name

  )

  SELECT u.*

  ROUND (100 * RATIO_TO_REPORT (units) OVER (PARTITION BY groupname)

  category_name

  )

  ) AS units_pct

  OF got_units u

  ORDER BY date_adjusted, category_name, GroupName

  ;

  Thanks for the display of the data of the sample; It is very useful.  Don't try to insert strings, for example, March 15, 2014", in DATE columns.  TO_DATE allows to convert strings to DATEs.

  Okay I need an increasing amount of space. However, at the same time I want to recover the spaces empty below HWM. So, I need to use less amount of space I am inserting. Therefore, shouldn't use retractable for this?
  >
  Why waste the effort. Oracle will reuse the space below the HWM when doing inserts. You already said that you insert more lines you delete so all these will be more accustomed to the top.

  The only time where that oracle may not use space is when the space is too small to be useful. It is documented in the doc, I told you
  >
  Understanding recoverable unused space
  Over time, Update, and Delete on objects within a tablespace can create pockets of empty space that individually are not large enough to be reused for the new data.

  Most uses of CONTRACTION I've seen are totally useless. If you follow the doc and run the Advisor of segment it will tell you if there is space that can be retrieved and how much. But, even once, for your use even if case will get you will Oracle while you need to reassign the new extensions, then the HWM will just go still higher.

  If pay you a heavy price in Oracle did a full table scan, update of many blocks from the table, update THE index, impact performance for other users to access the table during the SHRINK and reallocate extensions (maybe even some of the same areas) when you insert more data.

  Do not SHRINK unless you know it's necessary.

  (I know that I can use ForAll Update statement, but I do not want to use Collections here.)

  Thank you carine, finally I found my answer,

  the update query requires that each record that will be updated should be updated only once. so if I do join 1<->1 it updates successfully.

• Formulation of condition CQL with the source table and Javabean event

  Hello
  
  I managed to create a State in CQL that compares 2 values of TIMESTAMP between a source table and a Java bean.
  
  I did this by complying with the standard DATETIME SimpleDateFormat in the docs.
  
  But the format does not include milliseconds. Is there another way I can do this, without losing the value of millisecond of the Javabean?
  
  The request is something like
  
  Select table.*
  table, beans
  where table.sometimestamp < bean.startdate
  and table.sometimestamp > bean.enddate
  
  
  where bean.startdate and bean.enddate is a java.util.Date? (or all)
  
  I tried all kinds of combinations like to_timestamp (bean.startdate.getTime ()) but it is not the correct timestamp.
  
  Also tried to use types of java.sql. * but came through different CQL syntax errors.
  
  
  Any tips?
  
  Thank you!
  Jarell

  Hello

  I think you have two options:

  (1) to use SimpleDateFormat the of ' pattern. For example: "' yyMMddHHmmssSS', where the last two are the number of milliseconds.

  2) keep as a long (e.g. System.currentTimeMillis)

  Best regards

• Update statement with Date field

  I'm trying to run an update statement and I want to update the date in the format:
  
  04/05/2010 12:31:54
  
  If I run this query on the double it appears correctly: select the double to_char(sysdate,'DD/MM/YYYY HH12:MI:SS PM')
  
  If I run this well query on my table, I get a 'not one month valid' error.
  
  
  UPDATE WR_MEASURE_VALUE SET HOST_CORRECTED_VALUE = 35,
  HOST_CORRECTED_DATE = to_char(sysdate,'DD/MM/YYYY HH12:MI:SS PM') WHERE WR_MEASURE_VALUE_OID = 474066
  
  
  what I am doing wrong and how can I get my update statement to update date correctly in the ' HH12:MI JJ/MM/AAAA: SS PM' form?
  
  Thank you
  
  
  Guess all I had to say was HOST_CORRECTED_DATE = SYSDATE
  
  Thanks anyway
  
  Published by: Rich75 on May 5, 2010 07:10

  If you want:

  'UPDATE WR_MEASURE_VALUE SET ' || p_FieldToInsertUpdate || '=' || v_ValueAfterFactored || ',' ||
                                    v_DateToUpdate || '= to_date(''' || to_char(sysdate, 'dd/mm/yyyy hh12:mi:ss PM') || ''', ''dd/mm/yyyy hh12:mi:ss PM'')'||
  ' WHERE WR_MEASURE_VALUE_OID= ' || v_MeasureValueOID_arr(i) ||
  ' AND ' || v_Current_25Month_Value || ' != ' || v_DisplayValue;
  

  But... smacks of dubious design if you do not know what columns you update at compile time, IMO.

• Update statement with a subquery

• Update events with the same old and new values.

  Hello.
  I use simple replicated cache and subscription to update events to it with the ObservableMap #addMapListener (MapListener) method.
  The problem is that, in the case of update received old and new values are identical by operator is.
  The values are updated by the following scenario:
  E MyEntity = cache.get (myKey) (MyEntity);
  e.setName ("new name");
  cache.put (myKey, e);
  
  I have this problem only if there is a single node of the cluster, adding new nodes solves problem.
  
  How can I solve this problem for the server node?
  
  Currently I use the copy constructor to put the new object with modified fields to get two items in my interlocutor. Like this:
  E MyEntity = new MyEntity ((MyEntity) cache.get (myKey));
  e.setName ("new name");
  cache.put (myKey, e);

  Hello

  Yes, I suppose you could say that it is a 'feature' of a single node cluster. But given that nobody uses consistency as a single node cluster, I would say that this is not a problem; even your tests should not be done on a single node cluster. The whole point of consistency is it is on ladders to store data across many virtual machines Java, if you can organize all your data in a single JAVA virtual machine, and then use a hash table and save the cost and complexity of the use of consistency.

• Intelligence with sub form table and filtering of Ajax

  Hi all
  
  I manually built a tabular presentation with a client, registration and a checkbox to select those whom we want to choose for a given operation. It is very good and works fine, however, the customer list is very long and I am wanting to get a little clever with it and put in place Ajax filtering with a search field.
  This works also very well - I used the method described in the book 'Pro Oracle Application Express' (for those who don't have it, someone's blog the exact method, Word for Word, here) and the filtering works brilliantly, but the problem is with the checkboxes.
  I want users to be able to filter the list, a few boxes, re - filter the list and check a little more and then submit with all the parts retained and submitted.
  As is the nature of the Ajax call, all the boxes are deleted whenever you update the search filter string.
  
  Can someone suggest a method to achieve what I'm trying to do here?
  
  Thank you!

  Hello

  You may have a hidden page element (one that "saves the State") which contains a list of values for the checkboxes checked and updated immediately before the Ajax call. This article begins with a ': ' then add the value like ":" for each checked item - that would give you a string like ': 1:2:3: ' when the page is sent, you can then use STRING_TO_TABLE to get your list.

  The javascript code would be something like:

  function updateCheckedItems()
  {
    var x = document.getElementsByName("f01");
    var xx = document.getElementById("P1_CHECKED_ITEMS");
    var c;
    var v;
    if (x)
    {
      for (c = 0; c < x.length; c++)
      {
        if (x[c].checked)
        {
          v = x[c].value;
          if (xx.value.indexOf(":" + v + ":") == -1)
          {
            xx.value += v + ":";
          }
        }
      }
    }
  }
  

  This assumes that your boxes have a name of "f01" attribute, and the hidden item is P1_CHECKED_ITEMS

• Update modules with the capital letters and tiny rulename make the difference

  Hello
  
  I had a problem when I'm experiementing the code example in the semantic oracle developer guide. the sample is to update a modules-family_rb:
  
  UPDATE mdsys.semr_family_rb SET
  background = ' (? x: parentOf? y) (? y: parentOf? z) (? z: height? h)'.
  filter = ' (h > = 6)',
  alias = SEM_ALIASES (SEM_ALIAS (", 'http://www.example.org/family/'))
  WHERE nom_regle = 'GRANDPARENT_RULE ';
  
  in the last line, the where clause, the name of the rule (GRANDPARENT_RULE) is a capital letter; but it's tiny, when I inserted in modules. However, when I updated the modules by using the name of tiny rule, I got ' 0 inserted row"which means nothing updated. and, the following query returns the wrong result. However, if I've updated modules by using the name of rule of capital letters, I ' 1 inserted row"and the result of the query is correct. I thought that the uppercase and lowercase should made no difference. can someone tell me why the results are different? Thanks in advance.
  
  Kind regards
  Hong

  Salvation Hong,

  When a rule is inserted in a rules database, his name will be stored as all capitals.
  So what you have observed is expected.

  If you don't want to change the name of the rule manually, you can probably do something
  Like this:

  UPDATE mdsys.semr_family_rb SET
  background = ' (? x: parentOf? y) (? y: parentOf? z) (? z: height? h)'.
  filter = ' (h > = 6)',
  alias = SEM_ALIASES (SEM_ALIAS (", 'http://www.example.org/family/'))
  WHERE nom_regle = upper ('grandparent_rule');

  Thank you

• Cannot run a «BUSINESS...» WHEN ' with a date in a WHERE CLAUSE condition

  Hello

  I need to check for a condition and date according to the date, he would check a set of host names or the other game... so I thought I could write something like this in the WHERE clause:

  AND HOST_NAME IN

  (

  CASE

  WHEN TO_DATE (: StopDate, 'MON-DD-YYYY') > = TO_DATE ('22 - DEC - 2015 "," DD-MON-YYYY ') THEN

  ('SERVERNAMEA', 'SERVERNAMEB', 'SERVERNAMEC') ON THE OTHER

  ("SERVERNAME1", "NAMESERVER2", "SERVERNAME3")

  END

  )

  I get the following:

  ORA-00907: lack of right parenthesis

  00907 00000 - "lack the right parenthesis.

  But there is no missing parentheses!

  If I take the case... when... end, and run the host_name in ('SERVERNAMEA', 'SERVERNAMEB', 'SERVERNAMEC') (separately, they run fine)...

  I also tried:

  AND

  (

  CASE

  WHEN TO_DATE (: StopDate, 'MON-DD-YYYY') > = TO_DATE ('22 - DEC - 2015 "," DD-MON-YYYY ') THEN

  HOST_NAME IN ('SERVERNAMEA', 'SERVERNAMEB', 'SERVERNAMEC') ELSE

  HOST_NAME IN ('SERVERNAME1","NAMESERVER2","SERVERNAME3")

  END

  )

  the error I get is:

  ORA-00905: lack of keyword

  00905 00000 - 'lack the key word'

  What keyword miss me?

  Hello

  It was a typo when transferred to the Oracle forum... the version of Oracle is: PL/SQL version 10.2.0.3.0 (10 G)

  I also used IF the statement and that has not worked (in error "missing parenthesis") which I'm sure is a matter of "syntax"... I did not know that the CASE statement returns the value single only, so it's probably the problem.  Is it possible to re - write this?

  ...

  IF only works in PL/SQL.  It does not in SQL, even if that SQL is embedded in PL/SQL.

  There are many ways to re - write the condition.  And here's one:

  AND ((host_name IN ('SERVERNAMEA', 'SERVERNAMEB', 'SERVERNAMEC')

  AND TO_DATE (: StopDate, "MON-DD-YYYY") > = TO_DATE ('22-DEC-2015', "MON-DD-YYYY")

  )

  OR (host_name IN ('servername1","Nameserver2","SERVERNAME3")

  AND TO_DATE (: StopDate, "MON-DD-YYYY")<  to_date="" ('dec-22-2015', ="">

  )

  )

  If: StopDate can be NULL, it must be a bit more complicated.

  You can also use nested, such as CASE expressions

  AND THE CASE

  WHEN TO_DATE (: StopDate, "MON-DD-YYYY") > = TO_DATE ('22-DEC-2015', "MON-DD-YYYY")

  WHILE CASE

  WHEN host_name IN ('SERVERNAMEA', 'SERVERNAMEB', 'SERVERNAMEC')

  AND THEN 'OK '.

  END

  OTHER CASES

  WHEN host_name IN ('servername1","Nameserver2","SERVERNAME3")

  AND THEN 'OK '.

  END

  END = 'OK '.

  I wonder if this in your application is the best way, however.  If SERVERNAMEA was put into service on December 22, maybe that that fact should be recorded in a table.  If you have a table with 1 row per server, you can consider adding 2 columns DATE to show when the server was first and last used.  Then, rather than use a WHERE clause to test servers appropriate, you could do an inner join.

• Case statement with multiple queries to the THEN clause

  Y at - it a syntax something like:
  
  Case
  
  When A = 1
  Then B: = 2 and C: = 3
  
  When A = 2
  Then B: = 4 and C: = 5
  
  Else B: = 6 and C: = 7
  
  End case;
  
  where clause can then have multiple assignments?
  
  Also, how to mark entries as code on this forum?
  
  TIA,
  
  Extreme Farley

  You can simplify a bit:

  SQL> declare
    2     a number := 0;
    3     b number := 0;
    4     c number := 0;
    5  begin
    6
    7     Case A
    8          WHEN 1 Then
    9            B := 2;
   10            C := 3;
   11          WHEN 2 Then
   12            B := 4;
   13            C := 5;
   14          Else
   15            B := 6;
   16            C := 7;
   17     End Case;
   18     dbms_output.put_line('A=' || a);
   19     dbms_output.put_line('B=' || b);
   20     dbms_output.put_line('C=' || c);
   21  end;
   22  /
  A=0
  B=6
  C=7
