  It depends on what you expect. If you issue count (*) you ask Oracle "how many lines there. If you issue a County () you ask Oracle 'how non null values for are there. "

  delete from 
  where  is null;
  

  Ideally you would simply place a NOT NULL constraint on the column in question, thus prohibiting NULL values into the system (assuming that your business needs, it is that the column MUST always have a value).

  You seem to always have the same problem, but give it different titles. It would be much easier that you would hold a thread open until its resolved. The last time you had this problem that I posted the following code, it didn't help you? (Replace x and y in each if or ELSIF with the calendar you want to watch)

  CURSOR cr IS
    SELECT CODE,
           DATE,
           TIME
      FROM FROM TEMP_ATTENDANCE
     ORDER BY CODE, DATE, TIME;
  BEGIN
    FOR rec IN cr LOOP
      IF rec.TIME BETWEEN x AND Y THEN
        -- Update record for last day
        ..
      ELSIF rec.TIME BETWEEN x AND Y THEN
        -- Update record
       ..
      ELSIF rec.TIME BETWEEN x AND Y THEN
        -- Update record
       ..
      ELSIF rec.TIME BETWEEN x AND Y THEN
        -- Update record
       ..
      ELSIF rec.TIME BETWEEN x AND Y THEN
        -- Update record
       ..
      ELSIF rec.TIME BETWEEN x AND Y THEN
        -- Update record

• How to find if the data in the table are distributed on multiple disks

  Hi all
  
  I have a question on parallel processing.
  
  Assume that the Oracle (11 g 2) database is installed on a 12 CPU hardware has 24 independent labels, then I guess it's that we can have a maximum of 12 DOP.
  
  But if the table on which I use the parallel market that spans only 4 discs then the above 4 parallelism will degrade the performance of the query.
  
  My question is how do I know if the data in the table are spread over the number of disk drives, so that we can properly apply valid parallel operations on the table.
  
  Appreciate your valuable contributions here.
  
  Thank you
  MK.

  Just think logically.

• How to add data to the table using Manager POST for restful Apex application

  Hi all

  I managed to create a service application web Manager restful using GET for the Restful service module. I am able to get the data in row on the presentation of a table row id in the application. But I can't find an appropriate example, how the new data in the table can be posted or deleted. I created a POST handler for a URI scheme and look forward on how to proceed. Any help would be really appreciated.

  Source for the POST Manager:

  Start

  insert into ALL_BOOKS values(:id,:book);

  end;

  Also created 2 parameters id and the book.

  Check out the following tutorials OBE, that explains the creation of GET and POST RESTful Web Services and how to use them in the APEX.

  • Creation and use of RESTful Web application services Express 4.2
  • Creation and use of RESTful Web application services Express 5.0

  Also what yo mean "looking forward on how to proceed? Do you want to or created for use/consume in your Oracle APEX application hosted RESTful web services?

  If Yes, in your Application, you must create a RESTful Web Service reference -> shared components. Then, create a form/report based on Web Service reference.

  In this way, you can specify the Boolean parameter or omit it if you choose to use named parameters:

• How insert/DML data in the table when the data in the related table changes

  Hello guys!
  
  I came across a problem that I need to get fixed. Because I don't know how to start and get it resolved I wanted to ask you for your expertise.
  
  The scenario is as follows:
  
  I have a table 'a' in my 10g database and a view "ab" which combined table 'a' with 'b' table in a view. However, the 'b' table is a table in another schema Manager database. and accessible (read only right) via a database link.
  
  Now here it is: whenever the data changes in table "b", for example 2 new sets of data is inserted, I need to insert automatically the 2 values of these 2 sets of data in my table "a". Same procedure for update and delete in table "b".
  
  The action that inserts data into the table 'a' must be initialized in my database, I have limited access to the other. Can I somehow use a trigger my reviews of "ab" to insert data into the table "a"? Or is it possible to use the "change notification procedure database" using the view as the reference?
  
  Desperately need help and example of all suspicion/code greatly appreciated. I am very new to Oracle and not very fond of PL/SQL routines. So please be so kind as to give me more details.
  
  Thanks in advance - I hope you have any ideas how I can get this problem resolved.
  
  Sebastian

  >

  ... it does not, since the DDL operations are not permitted on the remote databases (ORA-02021). I can't create the trigger on a view either. :-(
  So what ways are left to insert data into the table 'a' when the related table changes?

  Please, help if you have an idea!

  Yes,
  You can't perform the DDL (create the trigger...) on remote databases as you can see...
  Try to create this trigger in the local database that will make DML (insert into...) on the remote database.

      CREATE OR REPLACE TRIGGER local_forward_pt_after_insert
       AFTER INSERT
           ON N2K_INV_PT
           FOR EACH ROW
  
       BEGIN
           -- Insert records into table "a"
           INSERT INTO TBL_PUNKTDATEN@remote_database_sid
            ( INT_NUMMER,
              STR_GEBIET
               )
           VALUES
            ( :new.INT_INV_PT_NR,
              :new.GEBIET );
       END;
  

  Thank you

  I often do.  Take each of your eight Boolean and consolidate them in a table, convert the table number and select your case on that based on the number.  Thus, if the first fifth suite and boolean (from above) are true, you have 25 case (10011000 = 25).  You can have a case manage multiple values, separate them with a comma in the selector.  It will make you famous.

  

  I do the same thing, but the value of the radix of the binary display case.
