  But what you can do...

  Try to create a new stored procedure, which returns the type of the database object.
  In this procedure, you can call the original procedure.
  Take what it returns and make the type object. That's what you need to retrieve your procedure ;-) (.. .huh?)

  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'

• How to write a function to estimate the number of rows returned SQL?

  How to write a function to estimate the number of rows returned SQL through SQL Execution Plan?
  My idea is
  Call dbms_sql.parse to create the SQL PLAN, then ask the PLAN for the number of estimated return lines.
  But how to get SQL plan through "id cursor?
  Thank you.

  You can use EXECUTE IMMEDIATE to explain plan statement. About the STATEMENT_ID generation, it could be anything. Even a SYSTIMESTAMP cast as TANK would work.

• Determine the number of rows returned by a cursor

  I have a problem when I need to use slightly different logic based on whether or not a cursor returns a single line or multiple lines. I know you can use % ROWCOUNT to determine the number of rows returned far+, but it's not really help me because I need to know this information before I start to do any treatment.
  
  
  In other words. How can I know the number of rows returned by a cursor without actually iterate through the entire thing.
  
  I'm looking for something like this:
  

     Cursor ReqCursor(pi_cert_id IN Varchar2) Is
        SELECT course_id cid, grade g
          FROM requirements
         WHERE cert_id = pi_cert_id;
     c_ReqCursor ReqCursor%Rowtype;
  
  Open CertCursor(p_cert_num);
      Loop
          Fetch CertCursor
            INTO c_CertCursor;
          Exit When CertCursor%Notfound;
          
          If c_CertCursor%NumOfRows > 1 THEN
              Case A;
          Else
              Case B;
          End If 
     End Loop
  Close CertCursor;

  For your business add

   SELECT course_id cid, grade g, count(*) over() Tot_Rows
          FROM requirements
         WHERE cert_id = pi_cert_id;
  --"Fetch 1st row and you will know if the cursor has more than 1 row"

• How do to display the number of rows Inserted/deleted etc. in PL/SQL

  In Oracle 10 g PL/SQL, I have a delete statement in a stored procedure. This isn't in a cursor. I want to see the number of lines that I deleted. I can use dbms_output.put_line package. I should know this, but I don't have time to perfect syntax. How do I get the number of rows that are deleted and the display via dbms_output.put_lline?

  For example:

  set serveroutput on
  
  begin
  
     delete  dept;
  
     dbms_output.put_line(sql%rowcount);
  
  end;
  /

• How to determine the number of rows in the database and save the result to a local variable?

  Hello

  I'm a newbie in the use of TestStand, databases and SQL, and now I've met difficulties. I use TestStand 2014 (32 bit).

  I have a need to know the number of rows in a database and save that number in a local variable. I tried to practice using the database of the Types of step provided with TS. I tried to use the following in a SQL statement:

  Locals.NumberOfRows = ("SELECT COUNT (*) FROM TEST_TABLE")

  It returns an error: specified value is not the expected type. My goal is possible in this way, or I'm doing this completely wrong?

  -RautSa

  Thank you for your response, Norbert. I have a database of who wins new values at random, and sometimes I need the exact number of rows in this table.

  I managed to achieve my goal by using the SQL statement: "SELECT COUNT (*) as Rowcount OF TEST_TABLE", followed by a data GET operation, which records that number of lines in a local variable.

• 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

• 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.

• Limit the number of rows retrieved

  We have the need to limit the number of rows retrieved in a table for some users.
  
  We tried to put this by adding a policy that limits the number of rows. Here is the code:
  
  
  create or replace function
  usu01_access_policy
  (obj_schema varchar2, obj_name varchar2) return varchar2
  is
  d_predicate varchar2 (2000);
  Start
  If the user = "PEPE01" then
  d_predicate: =.
  "rownum < 11';
  on the other
  d_predicate: =.
  ' 1 = 1' ;
  end if;
  Return d_predicate;
  end;
  
  This code works well when you query the table like this:
  
  Select * from usu01;
  
  the number of rows retrieved is 10.
  
  But when we define a clause 'where' the query does clause 10 recovered lines before, getting only the lines of the first 10 with the condition 'where' = true.
  
  Is there a way to limit the number of retrieved rows from a table, but by first applying the 'where' clause to the whole table and later the ' rownum < limit ' condition?
  
  Thank you

  Why do you limit the number of lines of output? It is a customer number, not a database problem, I would say.
  Which should be resolved within the query itself. Using rownum without orderly subquery also return different results on each run.
  Take a look here for top - N query: http://www.oracle.com/technetwork/issue-archive/2007/07-jan/o17asktom-093877.html

• Text box layout problem - and the number of rows displayed

  Hello
  
  Wonder if you can help with my 2 problems
  
  1. when I create text boxes, the label is displayed to the left of the text box. How can I display label above the text box
  CGH
  
  Label
  TextBox
  
  Instead of
  
  Text box label
  
  2. when I ask report showing my data, that it shows that 15 records per page, for the next set of records, I need to click on the following icon at the bottom of the table to go to the next page.
  How can I view all on the same page?
  
  Thanks for help

  1. simply check this using the Horizontal / Vertical alignment of attribute in the section of the label of the element of the Page definition.

  2. in the report of the attributes, the value of the plan of paging None; and the number of rows and number of maximum lines to more than the number of rows that will be returned by the report query.

  (You should only ignore this last you really know that the number of lines make this a reasonable option.) Nobody is going to want to scroll through thousands of lines or wait 5 minutes for total information overload. You wouldn't be popular with your admins/ISP network due to the excessive bandwidth consumed either.)
