total number of rows returned, how to learn it

Hello
I think that in Oracle should be some simple var which contains the number of rows returned, can someone help me with this.
I actually do it:
INSERT INTO TT_1 SELECT * FROM TT_2 WHERE COND_01.

Here so get the total number of rows populated without COUNT (*) extra.

TX
TR

If you want to see in PL/SQL you can do it like this:

SQL> set serveroutput on
SQL> create table t1 as select * from all_tables where 1 = 0;

Table created
SQL> BEGIN
  2    INSERT INTO t1 SELECT * FROM all_tables;
  3    dbms_output.put_line('Rows inserted: ' || SQL%ROWCOUNT);
  4  END;
  5  /

Rows inserted: 2238

PL/SQL procedure successfully completed

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.

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'

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 to display the total number of rows in the dashboard
Hello

I have a dashboard report for retrieving the list of projects and details, it grows on a daily basis, instead of users downloading the report and find out the total number of projects, I want to display 'the total number of projects' alone in the dashboard. How can I do?

Also is it possible to do like a pop up or something a little flash news - not necessary, but will be very good if I can do it.

Thanks for your time and your help.
create a report and a column to write a column invert the function max (rcount (1)). Call this column depending on the position of the column (as @1) in narrative mode.
You can view only the narrative in the dashboard.

for flash type of report, you can use the ticker view and call the same column in the view.

Count the total number of rows found in the schema

Count the total number of lines present in the schema, including the table, sequence, view

Desirable output

Table sequence views
20 of 1000 1000

Do you mean that you need to count the number of Tables, views and sequence present in the schema?

Hi something like that.

SELECT a.view_cnt AS "View Count", b.tab_cnt AS "Table Count",
       c.seq_cnt AS "Sequence Count"
  FROM (SELECT COUNT (*) view_cnt
          FROM USER_VIEWS) a,

Gives you,

How to limit the number of rows returned in the PIF
Hi friends...
How to restrict the no of lines displayed from a few 10 rows for example... at the BEEP
If its in RTF, you can use position to restrict.
<><11]?>

You can also restrict the it in your sql query using ROWNUM.

Number of rows returned by Rownum

Hello

When I run this code I get 8 rows where I see that the rownum is repeated twice. Why the rownum is repeats and if yes why alone2 times?

set serveroutput on ;
 begin
    for item in
    (
      select rownum as r, first_name||' '||last_name as full_name,salary*10 as dream_salary from employees
      where rownum <5
      )
    loop
      dbms_output.put_line(item.full_name||'dreams having'||item.dream_salary||' '||item.r);
    end loop;
  end;
  /

This is the result I get:

Steven King dreams having 264600 1
Neena Kochhar dreams having 170000 2
Lex De Haan dreams having 170000 3
Alexander Hunold dreams having 90000 4

Steven King dreams having 264600 1
Neena Kochhar dreams having 170000 2
Lex De Haan dreams having 170000 3
Alexander Hunold dreams having 90000 4

I have 107 lines.
Employees of the table contains the following columns

 desc employees
Name           Null     Type         
-------------- -------- ------------ 
EMPLOYEE_ID    NOT NULL NUMBER(6)    
FIRST_NAME              VARCHAR2(20) 
LAST_NAME      NOT NULL VARCHAR2(25) 
EMAIL          NOT NULL VARCHAR2(25) 
PHONE_NUMBER            VARCHAR2(20) 
HIRE_DATE      NOT NULL DATE         
JOB_ID         NOT NULL VARCHAR2(10)

COMMISSION_PCT          NUMBER(2,2)  
MANAGER_ID              NUMBER(6)    
DEPARTMENT_ID           NUMBER(4)    
LEFT_DATE               DATE

When I use-

       select rownum as r, first_name||' '||last_name as full_name,salary*10 as dream_salary from employees
      where rownum <=5

I get 5 rows with the correct rownums.

Thank you in advance

My guess is that you initially run it without defining the serveroutput on. If the results of the two rounds.

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.

Count the number of rows in a table (s)

How to get the total number of occurrences based on the value of a column.

Hi all

It is the first time I'll ask the question here on your forum, but since then followed several threads. I guess it's now my turn to ask a question. Anyway here's the thing, I have a query that should return to count the number of rows based on the value of HOUSING. Something like this:

-----

WIPDATAVALUE          SLOT             N            M
1-2                   TRALTEST43S1     1            3
1-2                   TRALTEST43S1     2            3
3                     TRALTEST43S1     3            3
4-6                   TRALTEST43S2     1            4
4-6                   TRALTEST43S2     2            4
4-6                   TRALTEST43S2     3            4
7                     TRALTEST43S2     4            4

-----

As you can see above, on the TRALTEST43S1 of the SLOT, there are three occurrences, so M (Total number of occurrences) must be three and this column N he's counting. It is the same with the TRALTEST43S2 of the SLOT. It's the query I have so far:

SELECT DISTINCT
WIPDATAVALUE, SLOT
, LEVEL AS n
, m 
FROM
(
  SELECT
    WIPDATAVALUE
    , SLOT
    , (dulo - una) + 1 AS m 
  FROM
  (
    SELECT 
      WIPDATAVALUE
      , SLOT
      , CASE WHEN INSTR(wipdatavalue, '-') = 0 THEN wipdatavalue ELSE SUBSTR(wipdatavalue, 1, INSTR(wipdatavalue, '-')-1) END AS una
      , CASE WHEN INSTR(wipdatavalue, '-') = 0 THEN wipdatavalue ELSE SUBSTR(wipdatavalue, INSTR(wipdatavalue, '-') + 1) END AS dulo
    FROM trprinting
    WHERE (containername = :lotID OR SLOT= :lotID) AND WIPDATAVALUE LIKE :wip
  )
) CONNECT BY LEVEL <= m
ORDER BY wipdatavalue;

And it leads to something like this:
-----

WIPDATAVALUE          SLOT             N            M
1-2                   TRALTEST43S1     1            2
1-2                   TRALTEST43S1     2            2
3                     TRALTEST43S1     1            1
4-6                   TRALTEST43S2     1            3
4-6                   TRALTEST43S2     2            3
4-6                   TRALTEST43S2     3            3
7                     TRALTEST43S2     1            1

-----

I think that my current query based results M and N on WIPDATAVALUE and not HOUSING that's why I get the wrong result. I also tried to use WITH instruction and it works well, but unfortunately, our system cannot accept the subquery factoring.

I know that you guys will be of help because you are all awesome. Thank you all

Hi sb92075,

You are right that it is available with this version. But our system doesn't put queries that use subquery factoring.

What system are you talking about? If you really have something that prevents you from using all the features of Oacle, you should seriously think about fixing it.

Any other ideas on how we can do this without help WITH clause?

Yes; If a WITH clause is referenced that once, it can be re-written as a point of view online:
