• Delete records based on the foreign keys of oracle 11 g

  I have a requirement to remove the records from the tables in the order according to

  the existing foreign keys.

  I for example, the following tables and the pk, fk constraints:

  create table one

  (aa number (1),)

  descr varchar2 (20));

  ALTER table one

  Add constraint a_pk key (aa) primary;

  create table b

  (aa number (1),)

  descr varchar2 (20));

  ALTER table b

  Add constraint b_pk key (aa) primary;

  create table c

  (aa number (1),)

  descr varchar2 (20));

  ALTER table c

  Add constraint c_pk key (aa) primary;

  create table a2

  (aa number (2),)

  id_aa number (1).

  descr varchar2 (20));

  ALTER table a2

  Add constraint a2_pk key (aa) primary;

  ALTER table a2

  Add constraint a2_fk foreign key (id_aa)

  references a (aa);

  create table b2

  (aa number (2),)

  id_aa number (1).

  descr varchar2 (20));

  ALTER table b2

  Add constraint b2_pk key (aa) primary;

  ALTER table b2

  Add constraint b2_fk foreign key (id_aa)

  references b (aa);

  create table z

  (aa number (3),)

  id_aa number (1).

  id_bb number (1).

  descr varchar (20));

  ALTER table z

  Add constraint z_pk key (aa) primary;

  ALTER table z

  Add constraint z_fk1 foreign key (id_aa)

  references a (aa);

  ALTER table z

  Add constraint z_fk2 foreign key (id_bb)

  references b (aa);

  So, I want to choose the names of the tables in such an order so as

  deleting records will succeed...

  I built the following sql query (using the recursive subquery factoring):

  [p]

  with q (r_constraint_name, table_name, constraint_name, lvl) as

  (select table_name, constraint_name, r_constraint_name 1 lvl

  from user_constraints one

  where a.constraint_type = 'P '.

  Union of all the

  Select b.table_name b.constraint_name, b.r_constraint_name, q.lvl + 1 lvl

  from user_constraints b

  Join q

  on (q.constraint_name = b.r_constraint_name)

  where b.constraint_type = 'R '.

  )

  Select f.table_name, f.constraint_name, f.r_constraint_name, f.lvl

  q f

  [/ p]

  I want the results as the following list:

  Table-name

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

  B2

  A2

  Z

  A

  B

  C

  The table - B2, A2, Z - (in any order) must first referred in the list

  because they are based on the other three tables - A, B, C. Thus, in order to remove the

  A, B, C table records the B2, A2, table Z records must be beleted first.

  The query I posted above has the problem that it displays tables A2, B2 twice

  (1 because they have a pk and 2 because they have fk referring A, B relatively tables).

  Is there a solution for this problem?

  Note: I use db11g v2

  I wrote not all relationships of tables user_constraints (only argument constraint_name = r_constraint_name)

  Thank you

  I have a requirement to remove the records from the tables in the order according to

  the existing foreign keys.

  . . .

  The table - B2, A2, Z - (in any order) must first referred in the list

  A, B, C table records the B2, A2, table Z records must be beleted first.

  Is there a solution for this problem?

  Yes - the 'solution' is to use ON DELETE CASCADE, as appropriate or write a procedure that removes tables in the proper order.

  The solution is NOT to try to use dynamic sql statements to do so.

  You already know the good parent/child relationships. Simply create a procedure that uses the correct order.

  Analyses are necessary in any case to determine the proper order AND press the appropriate values to use to remove the appropriate lines

  Your DDL for tables and constraints must be in a version control system

  Update the procedure when / if new constraints or tables are added to the application

  IMHO, you must use dynamic SQL NOT to try to adjust automatically if a new constraint appears. New constraints should not appear by accident - they appear ONLY as part of a well planned release.

• Poller DB to select records based on the timestamp

  Hi all

  I want select records from the coloumn timestamp where the timestamp is older than an hour. Is it possible to do this through poller db? I tried but unable to pass the dynamic value (currently - 1 hr)

  Thanks in advance!

  Eventually create a view based on the timestamp and singled out the dbpoller view.

• Need to set the attribute of the current record based on the value of the next record

  With the help of forms 6, I have a form that displays the list of folders. There may be multiple records with the same ID, but with different expiration dates. I need set attributes for hilite only the record with the latest expiration date. The current list points of interest reviews of future expiration dates - but we found that, sometimes, the subscription is renewed before the expiration date has been reached, causing two records with the same ID with expiry dates in the future.
  
  I can (and do) sort the records by date of expiry and the identification for the record with the latest expiration date is always the last to this ID, so what I want to do is to check the next record to see whether or not it has a different ID. If the current record is the last expiration date, & must be hilited. Because I might want to hilite the current record, I can't simply navigate to another record, according to the description I found, what makes the next_record builtin. Anyone know how I can check for a value in the next record without making the current record?
  
  Thank you.

  What I would do:

  -Create a DB view based on your table and including the function call DRIVE as a separate column.
  -Base that block you on this point of view
  -If the block is modifiable, set the DML target for the block to your database table.

  Hello

  You can use the ROW_NUMBER analytic function.

  I don't have a copy of your table, so I'll use scott.emp to illustrate.  In scott.emp, there may be several lines for a single job.  To display only 1 row per job, hiredate line with the most recent:

  WITH got_r_num AS

  (

  SELECT empno, hiredate-, deptno, job or whatever columns you want

  ROW_NUMBER () taken OVER (PARTITION OF work

  ORDER BY hiredate DESC

  ) AS r_num

  FROM scott.emp

  -WHERE--if you need a filter put it here

  )

  SELECT *- or the list of all columns except r_num

  OF got_r_num

  WHERE r_num = 1

  ;

  What results do you want in the case of links?  Depending on your needs, you can add expressions of tiebreaker to the analytical ORDER BY clause or the use of RANK instead of ROW_NUMBER.

  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.
  Point where the above query is to produce erroneous results, and explain, using specific examples, how you get the right results from data provided in these places.
  If you change the query at all, post your modified version.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  I am trying to remove the news that are published before 2012, but the tables in detail consists the notebook of the child based on the news_id has been. Request certainly simple deletion will not work
  
  Please advise and thank you in advance

  Once again, I tell you, do not need ON DELETE CASCADE in the Delete query.

  Just use the Delete query like: -.

  delete from news where TO_CHAR(news_date,'YYYY') <  2008;
  

  And the child tables are deleted as a result.

• Restrict the records based on the condition

  Select * from EMP where deptno = 10;

  O/P:

  7782	CLARK	MANAGER	7839	JUNE 9, 81	2450		10
  7839	KING	PRESIDENT		NOVEMBER 17, 81	5000		10
  7934	MILLER	CLERK	7782	JANUARY 23, 82	1300		10

  But I need 1 sheet with as described in condition.

  If JOB = 'MANAGER' pick this record

  If is not available, then choose JOB = 'PRESIDENT' record

  If is not available, then choose JOB = ' ' record

  A way

  Select * from)

  Select

  EmpNo

  ename

  work

  Manager

  hire_date

  salary

  deptno

  , rank() over (stopped in case of job when = "MANAGER", 1).

  When job = 'PRESIDENT' then 2

  When job = 'CLERK' then 3

  4 something else

  end

  ) rnk

  from EMP

  where deptno = 10

  )

  where rnk = 1

  If there is more than a Manager for example, the result would be more than one line.

  If you don't want that one line in these cases use row_number instead of rank.

  In this case, you want to refine the order by clause probably.

• Select records based on the monthly anniversary date

  Hello
  
  I have a table with a field of date_added and I want to select records from monthly birthday of this field.
  
  for example. ID, Date_added
  1, DECEMBER 10, 2012
  2, 11 NOVEMBER 2012
  3, 10 MARCH 2012
  4, FEBRUARY 28, 2012
  5, 30 DECEMBER 2012
  
  So for January 10, 2013, I would like to return the documents 1 and 3 only
  
  I started watching the extract function, but this little falls down to the records at the end of the month. For example, on 28 February, I also include records where 29, 30 or 31 is the day of date_added. So, in the above table, I won't return documents 4 and 5, but retrieves only returns 4.
  
  Is there a simple function to make the request of birthday this month - have I missed something very obvious? Or I have to write a query to explicitly dates at the end of the month? So far I have not found a reasonable solution!
  
  I use 11g
  
  Thank you

  Hi Al,.

  No I don't think that there is a flaw. For example, the 30 Jan is not the last day of the month, but is June 30. Thus, on 30 January I want only to interrogate all the dates falling on the 30th - 28 February, after already being interrogated on the 28 Jan. However, on 30 June, I would query the 30th of each month, as well as the 31 January, March, may, July, Aug, Oct, dec. February is a special case, being both shorter and a leap year

  Thank you

  Richard

  Hi Richard,

  so, we can assume that your needs are:

  If the day is the last day of that month, interview the day of the other months being > = day of the current month.

  That is to say:

  Jan-30 = query only 30 other months
  Jan-31 = query only 31 of the other months

  Feb-28 (non-leap years) = question 28, 29, 30 and 31 other months
  29 February (leap year) = query 29,30,31 to other months

  Mar-30 = query only 30 other months
  Apr-30 = query 30 and 31 other months

  This hypothesis is correct?

  If so, then something like this should work:

  WITH mydates(id, date_added) AS
  (
     SELECT 1, TO_DATE('10-DEC-2012', 'DD-MON-YYYY') FROM DUAL UNION ALL
     SELECT 2, TO_DATE('11-NOV-2012', 'DD-MON-YYYY') FROM DUAL UNION ALL
     SELECT 3, TO_DATE('10-MAR-2012', 'DD-MON-YYYY') FROM DUAL UNION ALL
     SELECT 4, TO_DATE('28-FEB-2012', 'DD-MON-YYYY') FROM DUAL UNION ALL
     SELECT 5, TO_DATE('30-DEC-2012', 'DD-MON-YYYY') FROM DUAL
  )
  SELECT id, date_added
    FROM mydates
   WHERE (:input_date = LAST_DAY(:input_date) AND TO_CHAR(:input_date,'DD') <= TO_CHAR(date_added, 'DD'))
      OR TO_CHAR(:input_date,'DD') = TO_CHAR(date_added, 'DD');
  
  with input_date = 28/02/2013
  
  id   date_added
  4    28/02/2012
  5    30/12/2012
  

  Kind regards.

• Audio recorder based on the Web in Flash

  I need to create a web-based audio recorder. I want to record and play audio data in GSM format (for telephony).

  I created the TI in JavaFX that require Java Runtime on the client side

  But Flash is preferred as Flash is everywhere and widely used.

  Is there a way to do this in Flash?

  You should not use FMS. The shared link earlier was one of the examples and you give an idea that is possible through flash. As I said earlier, take a look at the microphone and FileReferece APIs in AS3. Once you are familiar with these and then the following library might be useful for you to reuse or edit them directly: http://www.bytearray.org/?p=1858

• Select a record based on the date field MAX

  I have the following query that works, but does include all the necessary columns.  I need to JOIN the run_events table, which is a child of the runroute table, such that I choose not only the run_code and max event_timestamp, but also the LATITUDE, LONGITUDE columns.  Each run_code has many events associated with it.

  Any help or pointers would be appreciated!

  Thank you

  Hello

  One way is to use the MAX function analytical rather than the MAX aggregate, like this:

  WITH

  ETV as (select run_code

  LATITUDE, LONGITUDE

  , event_timestamp-* ADDED *.

  , max (event_timestamp) OVER (PARTITION BY run_code)-* CHANGED *.

  as TS

  of run_events

  -Group by run_code-* REMOVED *.

  )

  SELECT all THE RR.run_code,

  substr(PODDept.POD_NAME,1,10) DEPT,

  To_char (ETD ' HH: mi: SS AM') r_ETD,.

  To_char (ATD, ' HH: mi: SS AM') r_ATD,.

  substr (PODDest.POD_NAME, 1, 10) Dest,

  To_char (ETA, "HH: mi: SS AM'") r_ETA,.

  To_char (ATA, ' HH: mi: SS AM') r_ATA - if ATA is NULL, what's the point?

  ETV. LATITUDE, ETV. LONGITUDE

  to_char (VTE. TS, ' dd-mm-yyyy hh: mi: SS AM') TS

  OF routerun RR

  PADE LEFT JOIN PODDest ON RR. PODEST_CODE = PODDest.POD_ID

  LEFT JOIN PADE PODDept ON RR. PODEPT_CODE = PODDept.pod_id

  ETV LEFT JOIN ON RR.run_code = VTE.run_code

  AND VTE.event_timestamp = VTE.ts-* ADDED *.

  WHERE ATA IS NULL

  ORDER BY RR. ETA, RR. RUN_CODE

  /

  If you would care to post, CREATE TABLE and INSERT statements for some sample data and the results you want from this data, then I could test it.

  What happens if there is a tie for the final event_timestamp (i.e. 2 or more lines with the same exct run_code and event_timestamp)?  You can use the analytic ROW_NUMBER function instead of MAX.

• Separate records, based on the condition of a table

  Hello PL/SQL gurus and experts.
  
  I use Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64-bit Production version
  I have table-
  
  Note - Table do not have a primary key on Order_ID.
  

  DROP TABLE T;
  create table T(Order_ID,Active_Flg) as select
  '201002', 'Y' from dual union all select
  '201002', '' from DUAL union all select
  '201003', '' from dual union all select
  '201004', 'Y' from DUAL union all select
  '201004', '' from dual union all select
  '201005', '' from DUAL ;

  I want to go get these Order_ID who have Active Flg as NULL and do not have the entry for Active_Flg = Y
  
  If use the following, then it returns the distinct Order_ID but not the expected-

  SELECT DISTINCT ORDER_ID FROM T WHERE ACTIVE_FLG IS NULL;

  Result-

  ORDER_ID
  ------
  201004
  201002
  201003
  201005

  Kindly help...

  This?

  select order_id
    from (
            select order_id
                 , active_flg
                 , count(decode(active_flg, 'Y',1)) over(partition by order_id) cnt1
                 , count(decode(active_flg, null,1)) over(partition by order_id) cnt2
              from t
         )
   where cnt1 = 0 and cnt2 > 0;

  Hello
  
  I have a table with 3 fields,

  WITH t1 AS(SELECT 'P1' po_number,'R1' route_id,1900 route_cost FROM dual
  UNION ALL SELECT 'P1','R2',2300 FROM dual
  UNION ALL SELECT 'P1','R3',1100 FROM dual

  P1     R2     2300
  P1     R3     1100
  P2     R7    1200
  P2     R8    4500

  and I want to choose single route_id for a po_number where the cost is high
  and my output should be
  

  PO_NUMBER     ROUTE_ID     ROUTE_COST
  P1     R2     2300
  P2     R8     4500
