• 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.

• Can I get the total number of records that meet the conditions of a query using the Table API?

  Hello

  A < row > TableIterator is returned when I ask operations using the index of tables. If I want to get the total number of records, I count one by one using the returned TableIterator < row >.

  
  

  Can I get the total number of records directly meets the conditions of the query?

  I can get the total number of records directly the request of the meeting of the conditions of CLI using the command Global table - name tableName - count - index index-name-field fieldName - start startValue-end endValue.

  Can I get the same results using the Table API?

  I used MongoDB and NoSQL Oracle for about a year. According to the experience of the use of these dbs, I think mongoDB querying interface is powerful. In the contras, the query interface is relatively simple, which results is a lot of work that is usually a long time in the client side.

  Hello

  Counting records in a database is a tricky thing.  Any system that gives you an accurate count of the records will have a hotspot of concurrency on updates, namely the place where the counting is maintained.  Such a count is a problem of performance in addition to competitive access problem.   The problem is even more difficult in a system widely distributed such a NoSQL database.

  The CLI has overall command that counts, but does so by brutal force - iterate keys that correspond to the parameters of the operation.  This is how you must do this within the API.  There is not a lot of code, but you have to write.  You certainly want to use TableIterator TableAPI.tableKeysIterator (), because a key iteration is significantly faster than the iteration of lines.  Just one iteration and count.

  If you use TableAPI.multiGet () and a key with a touch of brightness full then, in fact, count the results as they are returned in a single piece (a list).

• Merge the queries based on the conditional

  Apex 4.2

  I have a pretty complex question. I have a page that will have a selection list on the data entry form. The selection list contains a list of both 1) Active only or 2) active and inactive areas. We show the active areas when we create a new record (P101_ID IS NULL), we appear active and inactive sectors when you edit a record (P101_ID IS NOT NULL). I have therefore two separate queries to account for each case. Simple so far.

  Problem I am seeing that create two lists of selection on the page and put a separate condition on each one (hiding one of selection lists depending on the case the ID IS NULL or the ID IS NOT NULL) does not work. So I was wondering if there was a way to combine queries for that to work based on a conditional statement. I did experiment with the instructions box and unions, etc., but my questions are a bit complicated. They are as follows:

  LIST OF ASSETS SECTORS (P101_ID is NULL)

  Select unique
  ISEC.inspection_sector_name,
  ISEC.inspection_sector_id
  From
  INSPECTION_SECTORS ISEC
  left join HWE_INSPECTION_SCHEDULING SCH on ISEC.inspection_sector_id = SCH.inspection_sector_id
  Where (ISEC.hurricane_protection_flag = :P157_IS_HURR and ISEC.river_protection_flag = :P157_IS_RIV) AND
  ISEC.superseded_date is null AND
  ISEC.commenced_date is not null AND
  ISEC.inspection_sector_id not in (
  Select ISEC.inspection_sectors_id
  From INSPECTION_SECTORS ISEC
  left join HWE_INSPECTION_SCHEDULING SCH on ISEC.inspection_sector_id = SCH.inspection_sector_id
  Where SCH.high_water_event_id = :P157_high_water_event_id AND
  SCH.inspection_date = :P157_inspection_date)
  OR ISEC.inspection_sector_id = :P157_inspection_sector_id AND
  ISEC.superseded_date is null
  Order by inspection_sector_name
  

  LIST ACTIVE AND INACTIVE SECTORS (P101_IS is NOT NULL)

  Select inspection_sector_name, inspection_sector_id From (
  Select ISEC.inspection_sector_name, ISEC.inspection_sector_id, '0' as this
  From dual, INSPECTION_SECTORS ISEC
  left join HWE_INSPECTION_SCHEDULING SCH on ISEC.inspection_sector_id = SCH.inspection_sector_id

  If the requests are quite complex. I tested the times and they work in APex, separately from the course. Forgive me if I have mispeled anything. But any help on this would be greatly appreciated. Thanks in advance.

  Thank you for taking to your friend Frank. You are a bird-guy (my attempt at sarcasm). Nobody has questioned whether its knowledge base; more so in the way he responded to my original post did not «do» Like the people who come on this forum looking for help to those who have greater knowledge, it would be nice to be greeted a little more friendly, lol. Just my thoughts. But, feel free to correct my spelling test, grammar and syntax in my sentences so (the effort once again to emphasize that I misspelled 'AND', and that the request would not be performed--> of course... smh... you are funny)

  Apparently I failed to explain the issue in its entirety. I should start by saying... "I have two separate petitions that I tested and already working and am looking to put on a list of selection (at the top) with a conditional execution statement one or the other, through the conditional statement, but again, I was looking for more so for syntax and structure." I'm sorry, I forgot to mention that.

  Anyway, enough of this. I found a solution to my problem:

  Within the Apex 4.2, you can have a list of selection as a page element. I want to display different results depending on whether Yes or no P101_ID is set to Null or NOT NULL

  P101_ID is a primary key for a table.

  P101_ID is not the exact name I use in my application / request however.

  In addition, you don't need to include double; It's not make or break the query. Something that I forgot to omit them.

  In addition, something along the lines of

  Select inspection_sector_name, inspection_sector_id From (
  .....all the stuff in query 1.......)
  Where P101_ID is null
  UNION
  Select inspection_sector_name, inspection_sector_id From (
  ....all the stuff in query 2.....)
  Where P101_ID is not null
  

  will work on a selection list in the APex. So problem solved. Thank you for all your wonderful insight, of words and thoughts. Thank you.

• Enable and disable the item based on the Condition

  Hi Experts,

  I work in the form of 10g, I conditionally.

  I have the block master detail.

  Master block contains sub elements.

  CUSTOMER

  Address (read only) - no database element

  PRODUCT GROUP (read only) - no database article

  Note: The CUSTOMER is LOV, when I select the customers, I'm failing address and product group.

  Block detail contains sub elements.

  DATE OF START OF BLOCK

  DATE OF END OF BLOCK

  REASON

  Note: when I opened form all fields of retail blocks are enabled

  Requirement:

  1. when I created new record, at the time where I select the customer name, Bill and product group will be by default, in the block of detail - I want to activate and deactivate the block start date based on the value of the product group.

  2 if I erase block master, I need to activate the block_start_date like back when the new form is opened

  3. when I search the data also, block start date must be enabled and disabled based on the value of the product group.

  Could someone help me the best approach to achieve so that she will have no side effects.

  Thank you

  Hello

  set_item_property ('block.block_start_date', enabled, property_false);

  On the other

  set_item_property ('block.block_start_date', enabled, property_true);

  end if;

  1. it is disable the Group field when I put the cursor inside if the product category is "Aviation", but I want it to be automatic at a time where it will default to the value of product category.

  2. If the master clear record, is not allowing return product group

  3 suppose that if enter new record category of products "Aviation", once I put the cursor inside, it's debilitating, let's say if I erase the main recording without saving the changes, it not again allows the Group of products, it is now status (disable) previous.

  4. in query mode, it is not disabling or enabling from a group of products.

  Help, please.

  Thank you

  Ok.

  1. put your code on this trigger after changing point that fills the default value in the product category.

  2. remove the trigger after change of product group.

  3 put the same code to trigger once - new - Record - Instance of the main block.

  Hope this helps

• Displaying an icon for each record, based on a condition

  Hi people,
  I'm developing an application that uses forms 6i with oracle 10g. I have the "Grant" and "Deny" options in my application. I have also two icons is TICK icon and next is WRONG icon.according to the corresponding status icons ("granted" or "Refused") should be displayed for me.for this i have used multi-record block composed of 10 documents. Here is my sample code.
  

  IF :STATUS.C_STATUS = 'GRANTED' THEN
            Set_Item_instance_Property('status.tick',VISIBLE,PROPERTY_TRUE);
                 Set_Item_instance_Property('status.tick',DISPLAYED,PROPERTY_TRUE);
                 Set_Item_Property('status.wrong',VISIBLE,PROPERTY_FALSE);
                set_item_property('status.wrong',DISPLAYED,PROPERTY_FALSE);
                   .............

  Using this code, I am able to get the visibility of icons, but it affects the entire column. For example, if the first status of cases is "granted" then TICK icon should appear to runtime.similarly if second status of cases is "denied" then ERROR icon should be displayed for me.but for me that the TICK icon is displayed for all 10 records if the State of the first record is "granted". How do the visibled corresponding icons according to status ("Granted" or "Refused"). Kindly give me a solution.

  Hello

  Well, I don't think you can do it by making visible or invisible button/item. I can share an idea to create two image files a given and one for refuse. Multi record block you create an element of the image (non-database) and read the image on this element in the post (at the block level) based on the State values that you so condition...

  TRIGGER = POST-QUERY (BLOCK-LEVEL)
  IF :STATUS.C_STATUS = 'GRANTED' THEN
    READ_IMAGE_FILE('image_path\access_given.JPG','JPG','BLOCK_NAME.IMAGE_ITEM_NAME');
  ELSE
    READ_IMAGE_FILE('image_path\access_denied.JPG','JPG','BLOCK_NAME.IMAGE_ITEM_NAME');
  END IF;

• 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.

• Retention of records based on the end of the calendar year

  Content using WebCenter 11 g and Records Management, I'm looking for a way to create a rule of provision based on the end of a calendar year.  For example, the rule might wait two years after the end of the calendar year in which the content item has been published.  Does anyone know how to do this?  I'm looking for something that is easy to maintain, but right now my best option is to create a metadata field to end of calendar year and then do a little iDoc script to set point which is archived for each content.  I would really like to avoid this if possible.  Any ideas?

  I think what you're trying to do is to "synchronize on the period start date.  It is part of the definition of the trigger.

  http://docs.oracle.com/cd/E21764_01/doc.1111/e10640/e01_interface.htm#RMDSG620.

  Assuming that the trigger is based on the release date:

  -An item is activated in June 30, 2016.

  -After the date of recording, wait two years.  This makes the eligible trigger on June 30, 2018.

  - But you want to wait until the end of 2018 to make available.

  -Check the above mentioned framework would force alienation to fire on January 1, 2019, instead of June 30, 2018.

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

  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

  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.

  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).

  Any data type, this column is or what are the values it contains, as long as you can derive from the order of the rows of values in the column.  (Of course, the values can be consecutive integers, only they do not have to be).  If you do not have this type of column, you don't have any order to your lines, and what you request is impossible.

  Since you have a load_order column, here's a way to get the results you requested:

  MERGE INTO dst t2

  WITH THE HELP OF)

  WITH got_grp AS

  (

  SELECT load_order

  paramlocation

  paramtype

  ROW_NUMBER () OVER (ORDER BY load_order)

  -ROW_NUMBER () OVER (PARTITION BY CASE

  WHEN paramtype IS NULL

  THEN 0

  END

  ORDER BY load_order

  ) AS the grp

  THE t2

  )

  SELECT load_order

  paramlocation

  ROW_NUMBER () OVER (PARTITION BY grp

  ORDER BY load_order

  ), Paramnum

  OF got_grp

  WHERE the paramtype IS NOT NULL

  ) CBC

  WE (dst.paramlocation = src.paramlocation)

  WHEN MATCHED THEN UPDATE

  SET dst.paramnum = src.paramnum

  ;

  Results:

  LOAD_ORDER PARAMLOCATION BY

  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.

• The default value based on the field from another table to a custom object

  I'm trying to set the default value to a field in the custom object to the value of a field of account. I tried the syntax 50 ways different and just don't get the case. The label for the account field displays the form of s/n, the integration of the tag is ltDBA_ACCT and it appears in the fx reports area as Account.Text_22.
  
  The field of custom object that I am triying update is also called s/n, which was originally the required field 'NAME '. The name of the table, account, should it be included? Do I need a function to the field?
  
  I've updated the external ID using the line with syntex < ID > ID (at least higher ID) so I know that it is possible to define a default value, but s / < n >, < ltDBA_ACCT >, 'account '. "" S/n "and so on are simply not working.
  
  If anyone knows how to get into what I would be really grateful for the help.

  OK, so if you default a field to the value of another object, you must use the JoinFieldValue function. I think you understand that, based on your original post, but I want to be sure you do.

  Then this won't work by default if the folder is created from the object that you want to join the because a default works in record creation and the ID must be available so that it works correctly. It will not work if you choose the record of the related object after that registration of the custom object is created. You can set the default after, but that does not meet your requirements.

  The syntax of the default are the following: JoinFieldValue (ref_record_type, foreign_key, field_name).

  In your case, ref_record_type is '', foreign_key is [] and field_name is ''. The best way is to determine what is the name of the field to create a new workflow for the account and use the Workflow Rule Condition expression builder to choose your field ("DBA") in the list. The value returned by the expression builder must be placed in the field_name variable in the function JoinFieldValue (minus the parentheses and quotes).

  Give it a shot and let me know how you do.
