• Count the number of rows in a table (s)

  Hi all

  I have a TKT_PRIORITY_LK table that I want to count the number of rows returned by a priority level... say Low, Medium, High, critical. I want to be able to count how many of each created are they, instead returning ID instead, if making any sense... Can you please help with this.

  Example; Select count (*) in TKT_PRIORITY_LK

  PRIORITY group

  Kind regards

  Sandrine

  Try this

  Select a.PRIORITY, count (*) from TKT_PRIORITY_LK a, TKT_TICKET_MAIN b

  where a.id = b.PRIORITY_ID

  A.PRIORITY group

  How can I add a last column that counts the number of rows returned by this view?
  
  EDIT - here is a dump of my paintings, and here are my views.
  
  Edit2 - this is possible by using the DECODE function, by chance?

  The function...

  CREATE OR REPLACE FUNCTION view_row_count (view_name VARCHAR2)
  RETURN NUMBER
  AS
  retval NUMBER;
  BEGIN
  EXECUTE IMMEDIATE
  'select count(*) from '||view_name INTO retval;
  RETURN retval;
  END view_row_count;
  /
  

  And now the query...

  select
  object_name,
  created,
  last_ddl_time,
  view_row_count(object_name) as view_row_count
  from user_objects
  where object_type = 'VIEW'
  

• Game max fixed the number of rows in a table

  Hi all
  
  I created a table that should contain only one line and avoid the possibility to add other lines to it, I used the following:
  

  CREATE TABLE <table_name> (
      <field_1> <field_type> unique,
      ...
      <field_2> <field_type>
      CONSTRAINT <field_1_ck> CHECK (<field_1> = <value>) 
  );

  It works, but it seems a bit heavy for me... Is there a better way to define a fixed/maximum number of rows in a table?

• Count the number of rising edges in table 1 d

  Hello

  I wanted to measure the frequency of a pulse signal using a MCC DAQ via libraries ULx in Labview. I have two methods to do this:

  1. use the analog inputs:

  Since data acquisition has only 1 ADC, I use a commune VI acquisition for all channels and create a multi-dimensional array with different channels in rows 0-15. Then divide them by using the function "Array Index".  I think this split removes the parameter 'time' to the wave, since it is now a table 1 d. But I already know that there will be 1000 samples each 100 m everything I want to do now is to count rising edges using a function and divide it by the 0.1 to obtain the frequency in Hz, but I don't know how. Can anyone help?

  2. use the input frequency meter:

  Because I can't use the DAQ assistant, I have to use the CI frequency-> counter 1ChanNSamp DBL 1 d in the ULx library. There is no reference to take aid to and I do not know if this method is good. I have no way of knowing since I do not have a signal generator. In addition, it does not work so far.

  Help, please.

  Thank you!

  Thank you.

  I note in your first post it is seems to want to get readings of speed about 10 times per second. To get a resolution of 1 Hz frequency direct count you need to get at least 2500 counts in a range of counting at the highest frequency. This means that you need to have at least a second. Measures of the time are another option.

  Some preliminary calculations:

  Period at 2500 RPM = 2500 Hz is 400,000 Americans.

  Period at 2499 RPM = 2499 Hz is 400,160 to the United States.

  You need to be able to resolve a difference of 160 ns period. To do this directly requires 6.25 MHz sampling rate.  It is 25 times faster that your DAQ card can enjoy.

  What other options are there? Consider only your Information.vi extract. He uses techniques of Fourier transformation and interpolation to find the frequency of a signal. I set up a quick test VI to check this. Using a sampling rate of 10 kech. / s and 1000 samples per read (10 reads per second), it has easily resolution of less than 0.1 Hz at both ends of the range of speed and largely independent of the amplitude.  This is the way to go.

• get the number of rows affected by their table top

  Hello, I need to count the number of rows updated in table form. In the process of ApplyMRU, I can use the string substitution #MRU_COUNT # to show the lines updated in a success message, but I need to get this value and store it on a table. Any help would be much appreciated. Thank you.

  For that you would benefit from the APEX$ ROW_STATUS integrated substitution string.

  1. create a page element display only (in my case P15_UPDATED_ROWS) Save Session State set to Yes and the Type of Condition is set to never.

  2. Add a calculation after the shows with a Type of static assignment and calculation value 0 to reset the counter whenever the page is sent.

  3. Add an On submit - after calculations and Validations process of PL/SQL page linked to your tabular presentation with a Status of Type PL/SQL Expression and Expression 1 :apex$row_status = 'U' and the code of the following process :

  :p15_updated_rows := :p15_updated_rows + 1;
  

  If you don't actually means "day" in the strict sense, and then change the status of process to include possible APEX$ ROW_STATUS 'C', 'U', and "D" values as needed. If you want to count all created, updated and deleted lines, do not add the condition to the process, but make sure the extended run is set to createand changed lines.

• count the number of occurrence in the table with toplink

  Hello!
  
  There is no way to create a query with the expressionbuilder or... to count the number of occurences in my table?
  I don't want to use the query " select count (*) from table .
  
  Thank you

  Not sure about the question. You are looking to get the SQL "select count (*) table" to use the framework of expression TopLink or pull you that SQL already and want something else?

  If you are looking just to get the count of a table/class, you can use a ReportQuery:
  ReportQuery rquery = new ReportQuery (ClassToQueryOn.class);
  rquery.addCount (); equivalent to count (*);

  session.executeQuery (rquery);

  You can use a report query to return data instead of objects and use the criteria for selection as a normal read request.

• Try to count the number of records where some columns are met

  Using SQL in Toad against an Oracle table, I'm trying to count the number of records in a table where some columns are filled. For
  example, I need to know the total number of records from a table where
  
  ln_stop_cd is not null - 65000 records
  ln_process_cd is <>- 25000 0 records
  ln_opt_cd is not null - 7500 records
  
  and the record_type = "A".
  
  I know that the total individual records as described above. However, I do not know how
  the SQL to show for record_type = 'A' the total count is 97500 records. Any help would be
  appreciated.

  Hello

  It seems that the problem is that the indictment may overlap; You can count the same rank 0, 1, 2 or 3 times, depending on whether 0, 1, 2 or 3 of these 3 independent conditions are met.

  Try something like this:

  SELECT     COUNT (in_stop_cd)
        + COUNT (CASE WHEN in_process_cd  != 0        THEN 1 END)     -- this site doesn't like the other inequality operator
        + COUNT (in_opt_cd)        AS grand_total
  FROM    table1
  WHERE     dt          >= TO_DATE ('01-JUN-2011', 'DD-MON-YYYY')
  AND     dt          <  TO_DATE ('02-JUN-2011', 'DD-MON-YYYY')
  AND     record_type       = 'A'
  ;
  

  You want to make charges without making 3 assists separated through the table. The problem is the 3 original requests had slightly different WHERE clauses.
  Put these conditions in the WHERE clause and make other conditions apply only to the individual counties, either with a column instead of *, or using a CASE statement that contains the condition that applies only to the column.

  Also, the date is not a column name good. Do not compare the DATEs to strings. If your column is really a DATE and you want to ignore the hours, the minutes and seconds, then the best way is to compare the column with 2 other DATES, as shown above. It's more coding, but it is more efficient and more reliable.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
  You don't have to display a large amount of data. You can probably give an excellent example of this problem with only 5 or 10 rows of sample data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• Get the number of rows in the oracle table

  Hi all
  I want to get the total number of rows in the sql to the appmodule table.
  After you apply the criteria to view some on the view object. If he try with getallrowsinrange the number of rows found within the viewobject was but I want a total number of rows in the sql table.
  
  How can I get that
  
  I use jdev 11.1.1.5
  
  Thanks in advance

  I threw something together, quick and dirty, don't hesitate to optimize.

  Assuming you want the County table, I put the code in a subclass of EntityDefImpl since it is representing a table in the middle tier.

  public class EmpDefImpl
        extends EntityDefImpl {
    /**
     * This is the default constructor (do not remove).
     */
    public EmpDefImpl( ) {}
  
    //~ Methods ****************************************************************************
  
    public long getTableRowCount( DBTransaction transaction ) {
      String query = getQuery( );
      String countQuery = String.format( "SELECT COUNT(*) FROM (%s)", query );
      long count = 0;
  
      ViewObject vo = transaction.createViewObjectFromQueryStmt( countQuery );
  
      try {
        vo.executeQuery( );
  
        Row row = vo.first( );
        Number number = (Number)row.getAttribute( 0 );
        count = number.longValue( );
      } finally {
        vo.remove( );
      }
  
      return count;
    }
  }
  

  Depending on your card type, you may not get an oracle.jbo.domain.Number, but something else, so the cast may need correction.

  Usage example:

  public class EmpEditViewImpl extends ViewObjectImpl {
    public EmpEditViewImpl() {
    }
  
    protected void executeQueryForCollection( Object object, Object[] object2, int i ) {
      super.executeQueryForCollection( object, object2, i );
  
      EmpDefImpl def = ( EmpDefImpl )getEntityDef( 0 );
      long tableRowCount = def.getTableRowCount( getDBTransaction() ) );
  
      // Do something with it
    }
  }
  

  As you can see, the code is fairly generic. Also, you might be able to put this in a base extension ADF class.
