  Explain the plan:

  

  Table1 a record 3Million and table 2 has 1 million records.

  I used gather stats before you run this query and 'Full' trick, even in this case, he is running for 45 minutes.

  Please suggest the best solution to optimize this query.

  Thanks in advance.

  Remove the tips.

  No need for the separate.

  Get the diff by ceil (abs(t2.m_date-t1.m_date)) and the filter for that where value_diff<>

  Assing the statement ".. MATCHED" lately in the update clause.

  Maybe give exactly to your needs with a small example may be the query may be getting more simplified or not what you want it to do.

• How to write this query?

  Hi people,

  I need to get a query in which a set of records, I get ONLY those which previous registry has a field with a value to this topic. Other values, the field can contain are not necessary.

  I know that sounds easy but... I can't get it.

  So, for Oracle 10 g 2... Here's my query:

  SELECT a.person_id, a.person_status, a.message_id, a.order_id

  OF t_HR one

  WHERE a.person_status = "rejected".

  AND a.id >

  (SELECT max (b.id)

  OF t_HR b

  WHERE b.person_id = a.person_id

  and b.order_id = a.order_id

  AND b.person_status! "revised =".

  B.ID AND < a.id)

  ORDER BY desc a.id

  Let me explain:

  1 - HR table is a table of people. These people has serveral STATUS.

  2 - ID is a sequential (each www.voyages-sncf.com has a different identification number).

  3 - the application must get THAT all people "rejected".

  4. - However, (subquery) I need ONLY those that previous register (the second register) holds a status of "OK". If the person holds a "revised" status he's not, he should be the next register (the third)

  5.-L' ORDER ID DESC, so is the first register must have a STATUS = "rejected" and the second a 'OK '.  IF the second register = "revised", then the third register must be 'OK '. And I need this query.

  HOW DO?

  My problem: the subquery gives you previous register of the same guy, but... it does not give you the value of the State, I need, which is 'OK '.

  I tried to add to the subquery...

  SELECT max (b.id)

  OF mod_human_resource b

  WHERE b.person_id = a.person_id

  and b.order_id = a.order_id

  AND b.person_status = 'OK '.

  AND b.id < a.id

  ... but if I have 5 records of that person, the first is "rejected", the second is "accepted", the third is 'new' and the fourth is 'OK'... the subquery gives you the 4th register and which is not correct for me, it must be only the second one (prior to the first State registry).

  I need to be a query, because I need to use it on a MERGER for a DWH.

  If there is another way (function, or even a procedure) to make the MERGER rather than with a request, which would be ok too. I am poor DWH knowledge.

  Thanks in advance.

  Hello

  So, you need to know if a line is the 'first' line, and you should also know what is the 'next' status, (even the 'first' and 'next' are already defined).  This sounds like a job for analytical functions.  ROW_NUMBER can tell you if a line is first or not, and LEAD can tell you what a value on the next row.

  Since you post CREATE TABLE and INSERT statements for your own table, I'll use the table scott.emp to illustrate.

  Consider these data from scott.emp:

  SELECT DeptNo

  ename

  work

  FROM scott.emp

  ORDER BY deptno

  ename DESC

  ;

  Output:

  DEPTNO ENAME JOB

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

  10 MILLER CLERK

  PRESIDENT OF KING 10

  MANAGER 10 CLARK

  20 SMITH CLERK

  ANALYST SCOTT 20

  20 JONES MANAGER

  20 FORD ANALYST

  20 ADAMS CLERK

  30 WARD SALESMAN

  SELLER OF 30 TURNER

  30 MARTIN SALESMAN

  30 JAMES CLERK

  MANAGER BLAKE 30

  30 ALLEN SALESMAN

  Now, let's say we want only who know the departments where the forefront (in order descending ename) a job = 'CLERK', and the following line (also in descending by ename order) = "ANALYST" job, and we want to know the ename of the first row.  In other words, the correct output is:

  DEPTNO ENAME

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

  20 SMITH

  Note that deptno = 10 is not included, even if the first task is to "CLERK." that was because the second job in deptno = 10 is the "PRESIDENT", not "ANALYST."

  Here's a way to get these results:

  WITH got_analytics AS

  (

  SELECT ename, deptno, job

  ROW_NUMBER () OVER (PARTITION BY deptno

  ORDER BY ename DESC

  ) AS r_num

  LEAD (employment) OVER (PARTITION BY deptno

  ORDER BY ename DESC

  ) AS next_job

  FROM scott.emp

  )

  SELECT deptno, ename

  OF got_analytics

  WHERE r_num = 1

  AND job = 'CLERK '.

  AND next_job = 'ANALYST '.

  ;

  I hope that answers your question.

  If this isn't the case, then, as Dan (and the FAQ forum) said, post CREATE TABLE and INSERT statements for some sample data and the exact results you want from these data.

  Post your query, based on the one I have posted more top and ponit out where he gets results.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• How to set this point as well COSTS in Oracle Asset R12.1.3

  Hello
  
  I created po and invoice with the assets of the clearing account or CIP Clearing and I transferred to the assets of the oracle. Prepare more mass, how can I set this as well COSTS. I already have active cost in the asset class.
  
  You need help!
  
  Thank you

  Hello

  If the query is "assets of Oracle can allow conversion of an asset Capital/CIP to a credit to expense at the stage of adding mass?"

  The answer looks like no.... I did a below test case myself to see the results.
  (1) created invoice to pay with the active account temporary, valid, approved, represents the invoice...
  (2) transferred to GL and linked the process of creating massive addition of accounts payable
  (3) asset, went to the screen adding mass to prepare...
  (4) questioned a line of addition of mass with the NEW status
  (5) in assets Details TAB, the type of property for my line is uppercase. I tried to change that in Expensed, while I can't change because the active type of expense is not listed in the drop-down options menu... I choose PAC or type of assets of the group, but not charged to the exercise...

  I tried another approach, by selecting a category (cool) for my line of massive addition, it will allow to change the type of assets or not... rather it throwed the below error message...

  «APP-OFA-48201 error: error incorrect asset Type and category combination for & stuff»

  In seeking the support of oracle with the above error reference came across the note below...
  165827.1 ID = APP-OFA-48201 when changing the category to prepare mass additions

  who says:

  "FA only allows assets reclassified between capitalized categories or between categories has expensed. Assets may not be reclassified between categories past expensed and capitalized. "

  I'm assuming that the conclusion or you can change the type of assets of immobilized to Expensed to the massive addition step prepared... .you could either remove the line and assets (load) to create manually...

  Kind regards

  Try something like this I tested with the substr function:

  SQL> select substr(pad,2,3) from t where id=368;
  
  SUB
  ---
  WET
  
  SQL> select substr((select pad from t where id=368),2,3) from dual;
  
  SUB
  ---
  WET
  

  I used the sql statement to replace the function parameter. Of course, it's stupid to use this way, if you do not need to do, but for your case, this could be a solution. In your case, you could write:

  FROM TABLE (ADMIN.find_record_dtl (
                       8,
                       (select SUBSTR(pc.pay_calendar_id, 0,3) from pr_calendar pc where  = SUBSTR(pc.pay_calendar_id, 0,3) = 'RET')),
                       'HQPRM003')
  

  Therefore, you put any sql that returns the correct value for your second parameter to your function entry. I hope that I wrote the right of expression, like yesterday, I got some garbage inside the text when I copied it.

  From the performance point of view I wouldn't function to extract the lines although it uses in BULK COLLECT but would rather use SQL function and integrate it within the main query and get something like:

  ...FROM( SELECT  DISTINCT pc.pay_calendar_id,
                   CASE WHEN ...
                   END AS pay_amount,
             rd.employee_id, cal_month, data_name, data_desc, data_seq
             FROM (SELECT distinct report_id, employee_id,  employee_name,
                                   pay_calendar_id, data_name, data_desc,
                                data_seq, display_name, section_seq,
                                item_id, base_amt, input_amt,
                                calculated_amt
                      FROM list_record_dtl) rd,
                          pr_calendar pc
               WHERE pc.pay_calendar_id = rd.pay_calendar_id
               AND   SUBSTR(pc.pay_calendar_id, 0,3) = 'RET'
               AND   rd.employee_id = 'HQPRM003'
                     and   rd.report_id = 8 ) a
           RIGHT JOIN ....
  

  So now you have two options yet :-)

  Generally, I would prefer rather to not use the service for the following reasons:
  (1.) the change of context between engine sql and pl/sql - Fortunately, in your case the function is executed only once (see column starts from your execution plan)
  2.) xxx of the instances of the type of data pay_item_t to the result of the query within the service may use lots of memory. This memory is allocated to the PGA and would be seen in v$ process_memory in the category 'other '. Of course, you can also monitor the consumption of memory of PGA of v$ sesstat. Now you will use the three parameters to the function and fewer rows returned as it was before, when the function has returned 192076 lines.
  3.) and the last one the more important one - if you use the online mode you give the CBO opportunity to optimize instruction. If you are using the CBO cannot push the predicates of main query within the query that is executed within the function and so it can be like a suboptimal plan even what exactly was your case when you started this thread. Was clearly the person who developed the conscious function of this problem and has tried to solve this problem by additional parameters that are passed to the function and are used to limit the number of rows returned by the function. Unfortunately these two parameters were not used in your case.
  4.) it is always a good practice using only the resources you really need and not much more!

• How to solve this query in database using sqlite phone gap

  am facing a problem in recent days. The problem is database. In fact, I create the mane database 'casepad '. Then I created a table because the database 'table of cases' have (ID, name, date). Now I insert the value on this table. When inserting I also create a name ("casename") .mean table if I insert the value of the case table (1, 'AB', 2/13). Then I create table AB. Now I need to get the value of the case table (I am) but I need to count the number of items in another table (AB). Here, I had to try it.

  function onDeviceReady() {
  
      db = window.openDatabase("Casepad", "1.0", "Casepad", 200000);
  
  db.transaction(getallTableData, errorCB);
  
  }
  
  function insertData() {
      db.transaction(createTable, errorCB, afterSuccessTableCreation);
  }
  
  //createtableandinsertsome record
  function createTable(tx) {
      tx.executeSql('CREATE TABLE IF NOT EXISTS CaseTable (id INTEGER PRIMARY KEY AUTOINCREMENT, CaseName  TEXT unique NOT NULL ,CaseDate INTEGER ,TextArea TEXT NOT NULL)');
  
      tx.executeSql('INSERT OR IGNORE INTO CaseTable(CaseName,CaseDate,TextArea) VALUES ("' + $('.caseName_h').val() + '", "' + $('.caseDate_h').val() + '","' + $('.caseTextArea_h').val() + '")');
  
  }
  //function will be called when an error occurred
  function errorCB(err) {
      navigator.notification.alert("Error processing SQL: " + err.code);
  }
  
  //function will be called when process succeed
  function afterSuccessTableCreation() {
      console.log("success!");
      db.transaction(getallTableData, errorCB);
  }
  
  //select all from SoccerPlayer
  function getallTableData(tx) {
      tx.executeSql('SELECT * FROM CaseTable', [], querySuccess, errorCB);
  }
  
  function querySuccess(tx, result) {
      var len = result.rows.length;
      var t;
      $('#folderData').empty();
      for (var i = 0; i < len; i++) {
  
          $('#folderData').append(
                  '
  ' + '' + '' + '
  ' + result.rows.item(i).CaseName + t+'
  ' + '
  ' + result.rows.item(i).TextArea + '
  ' + '
  ' + result.rows.item(i).CaseDate + '
  ' + '' + i + '' +
                   '
  EditDelete
  '+'
  '
                  );
      }
      $('#folderData').listview('refresh');
  
  }
  

  Instend of show the value of 'i' in the view list, I need to show how many element in the table. I have to call synchronize because I call a query that counts the number of elements to 'result.rows.item (i). CaseName"this item... ?

  Hello

  If I understand correctly, you are looking for a SQL statement that you will get the count for the number of items in the table AB? If so, this can be useful:

  Please let me know if you have any other questions.

• How to optimize this query XMLDB

  Hello dear community, we have two XMLType table they are very similar but not identical and we do not have the XSD for validation for this exercise.

  We need to make a join between these tables and the data code example go like that

  create table xmltst ( xmldata xmltype);
  create table xmltst2 ( xmldata xmltype);
  
  declare

  Create an index as above, but it does not seem to be used to explain the plan for the part of XML query.

  and a lot of time, I also get this error but I cannot now re - produce for some reason.

  I thought that its because I can't index after branch out according to s_ID

  SQL Error: ORA-29879: cannot create multiple domain indexes on a column list using same indextype
  29879. 00000 -  "cannot create multiple domain indexes on a column list using same indextype"
  *Cause:    An attempt was made to define multiple domain indexes on the same
             column list using identical indextypes.
  *Action:   Check to see if a different indextype can be used or if the index
             can be defined on another column list.
  

  and this index below seems to have choice as shown explain plan.

  Why can't I see the index above in the plan to explain it?

    CREATE INDEX "OE"."XMLTST_INDX01" ON "OE"."XMLTST" ("XMLDATA") 
     INDEXTYPE IS "XDB"."XMLINDEX"  PARAMETERS ('paths (include (/SWs/SW/@s_ID))');
  

  However, it is still the loop nest join when the join of two tables after the XML in the process... Is it possible to tell Oracle to a join index or some kind of faster join after the XML select part.

  My real case got way as many lines to make the join of X - Y and it may be nice to have an index to quickly reach?

  When do some small tests, the clause will eventually cause oracle core dump. It should not happen even it is a virtual machine with 3G of memory max and the max_memory_target = 800 M as all my data are not not even 50 M.

  We are the team of analysts and Dev team suggest that is a little too much time to contact Oracle Support and I finally create 3 global temporary table with commit preserve rows and operate with performance much better.
