Count total rows?

Hello,
In some function of my program, I need to count total number of rows but, I don't need to fetch results. Only the number of rows.
Is there any way to count the total number of result rows without fetch?
In OCI ver.7, it was very simple.
Just Call ofen() (OCIStmtFetch() in ver.8) without defining, but it's impossible that fetch without defining in Ver.8
Is there any idea to solve this situation?
I can defining and fetching just like normal process, but customer can send any SQL statement so, it can include LOBs.. and so on.
It's very waste source codes and memory for just counting rows.
Thank you

One possibility is to execute a different statement
(i.e. select count(*) from foo;) to get the number of
rows directly. This would probably be the most efficient
way to get the row count (since no row data is shipped
with this statement).
Unfortunately, I was unable to fetch rows w/o defining
in OCI either (I got an ORA-24374), so I am not sure how
you can get around this.
Incidentallly, when fetching LOBs, I don't think that
the entire lob is fetched, only the LOB locator. In this
case, there is very little over head associated with the
data transfer.
Also, I believe that ofen() was doing roundtrips in the
past, and my impression was that the latency of the
roundtrip to the server (and not the associated latency
of transferring the data) was the bottleneck here. Hence,
there may not be as much of a performance penalty as
expected for doing the extra client define with OCI
v8. So you still might be able to use your old ofen logic
(after replacing with OCIStmtExecute/OCIDefine) and not
see a very high performance hit.
Hope that helps out somewh

Count total rows in database?

Hello all,
Is there a way to query the database for the total number of rows.... without using ANALYZE STATISTICS? (That would cause the db to sometimes use COST instead of RULE based optimization, slowing it down significantly.)
I know I could could brute force a total row count with something like:
spool get_total_rows.sql
SELECT 'SELECT COUNT(*) FROM '||owner||'.'||table_name||';'
FROM ALL_TABLES;
spool off
...then run get_total_rows and manually add all the counts.
But it just seems like there must be a cleaner way to do it.
Thanks much,
Natasha

ok. here you have that information:

Count total rows in vo.

Dear All,
I have a af:showDetailItem in which i have a af:table. I want to show the total number of records in the header of af:showDetailItem.
example:
Employees (count=10)
So any one have any idea of how to solve this problem.?

Count total number of rows present in the schema

Count total number of rows present in the schema including table, sequence, view
Desirable Output
table          Sequence     Views
1000          20          1000

You mean You need to count the No of Tables, View and Sequence Present in the Schema ??
Hi Some thing like this,
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,
       (SELECT COUNT (*) tab_cnt
          FROM USER_TABLES) b,
       (SELECT COUNT (*) seq_cnt
          FROM USER_SEQUENCES) cWhich give you,
View Count      Table Count      Sequence Count

Present a total count of rows

I'd like to present a total count of rows in the bottom of a report.
how would you recommand me to do it???
the point is that it must be presented in each report so i thought to add some HTML code to "After Rows" section in the report template. but i need a variable (or some substitution string) which will contain the total count. but how do i define a substitution string?

as i mentioned i need to present a total count in the buttom of each report in my application. therefore I think it's reasonable to add a code in the report template, which present some variable which count all rows in a report.
#TOTAL_ROWS# doesn't work if i place it on the template html code, though it works fine if i place it in the report region definition:
 Total Number of Results: #TOTAL_ROWS#.
why can't i use #TOTAL_ROWS# as a template variable? and how can i do that?

The best way to do paging and get total rows count given a sql statement

Hi,
Just got a quick question.... what is the best way to do paging as well as the total rows count given by a sql statement.
e.g. "select * from emp"
1. I need to know the total row count for this statement.
2. I also need to do a 10 rows per page....
Is there a way to do it in a SINGLE statement for best performance?
Thanks experts.

Sounds more like a "formatting" problem...

Total row count - where from is that value?

Hi,
I need the value of total row count that is displayed at the button of portal report. I need this value to use in my java script.
Is that value somewhere in database? Maybe any variable or hidden form element on the page?
Where from does the portal know when to show only the previous button and when both next and previous? It must by calucated somehow.
Thanks in advance.
best regards

Thanks. Just to make clear:
Probelm:
I need to display links to pages with part of results at the bottom of page - just like in discussion group: Pages: [1] [2] [3] ....
Solution:
I know that there is a hidden form on every report rendered by portal. In that form there are several elements like:
pagenumer, minrow and maxrows. Updating these elements I can jump to every page with results.
Total row count problem:
The problem is that I don't know the number of pages. If I had a total row count value I would calculate the number of pages and create links only to existing pages.
best regards

3.0.9.8.5 - Total Row Count in reports

"Total Row Count" seems to be broken after applying patch 3.0.9.8.5.
After applying the patch, we viewed an existing report which returned (let's say) 25 rows (and I've got max rows per page set to 5):
The first page correctly says: "Total Row Count in Report- 25" and "Row(s) 1 - 5 "
But then clicking the 'next' button, the following page incorrectly says: "Total Row Count in Report- 10" and "Row(s) 6 - 10 "
So, the total row count is getting screwed up. Clicking "previous" in the example above, the total row count goes down to '5'.
Another 3.0.9.8.5 patch problem appears to be 5 extra 's within the report customize page top level of buttons and the criteria form. Looks ugly.

Thanks for the reply.
Is there nothing I can do to fix this problem before the next 3.0.9 patch comes out? We've have perhaps another few months to go before we make the move to portal release 2.
This one issue with patch 3.0.9.8.5 is mostly definitely a show-stopper for us...we cannot live with customers seeing errors as basic as "total rows" returned in queries....we will have to roll back to our previous patch level 3.0.9.8.3. By doing this, we will continue to get bad customer feedback because of the awful performance introduced by that patch (Internet Explorer HTTP 1.0 vs 1.1 / keepalives / SSL issue). That's not to mention that we won't see the benefits of the content-area export/import bug fixes in this latest pathset.
So, if there is ANYTHING we can do to fix this one problem, we (and our customers) would greatly appreciate hearing about it.
thanks,
-john

Add a row after Total row in ALV report

Hi Experts,
I have a report is displayed by ALV format(not use function module to display it but use Class cl_gui_custom_container),I want to add a row after the total row. for example,
Customer amount1 amount2 amount3
10000 1,234 1,000 2,000
10001 4,000 2,000 1,000
10002 1,300 1,000 3,000
11000 1,200 4,000 3,000
 Total: 7,734 8,000 9,000
Ratio% 31.27 32.34 36.39
the row of 'Total' is calculated by fieldcat-do_sum = 'X' But after the Total row we need a Ratio row to display the ratio. Yes we can calculate the total amout and ratio and then append it into the output itab, but we don't like this solution.We want to keep the total function in the ALV report.Any experts can poit me a direction. Thanks in advance.

Count of rows in ALv report

Hi!
I would like to get the count of rows in my ALV report . How to get the count of the rows ? Can anyone guide me in getting it dome please.
Thanks

Hi Gaddemmedi!
I am attaching the report as you had asked for. I have added the things you asked me to do and now I am getting the count on the top of the page. The problem is that though it shows me the count of the lines from the LAV report on top but when I try to filter the records in the report that count first of all dosent change and remain the same as the initial number of record though after filtering records reduce and over that the count lines keep on increasing I mean the count is shown in repeated lines afet lines. Kindly help please.

Count MySQL rows based off Value in Dynamic Table

Greetings all. I have 2 MySQL tables; 1 that contains the names of my classes.(Class A, Class, B, etc.) and 1 table that contains the names of students in each Class (for example Class A: John Doe; Class A: Susie Smith.; Class B: Jane Doe). In the 2nd table the Class name is in its own column and the student's name is in a 2nd column.
I currently have a dynamic repeating table that lists the names of all of the classes from the 1st table. What I'm trying to do is add a second column to this repeating dynamic table that lists the number of students in each class. For example; Row 1 of the dynamic table would say "Class A | 5; Class B | 3; Class C | 7, etc.). The dynamic table works perfectly to list the class names. For the life of me I can't figure out how to perform a count for each class to insert in the repeating table. I will be adding more Classes which as why I'm trying to set up the counting query dynamically. So far I have only been able to figure out how to count the total rows in the 2nd table, or count the rows with a specified class name. Any advice or guidance on how to count the number of rows in the 2nd MySQL table based off the class name in the repeating table is much appreciated. Thank you for any and all help. Have a great day.

Paging and count of rows

Hi,
I have a procedure doing paging and returning the count of rows:
As you see I used 2 select, one for paging and one for getting total row counts.
Is there a way to get rid of "SELECT count(*) into PO_TOTAL FROM TABLE1;"?
CREATE OR REPLACE PACKAGE BODY MYPACKAGE AS
TYPE T_CURSOR IS REF CURSOR;
PROCEDURE SP_PAGING
PI_STARTID IN NUMBER,
PI_ENDID IN NUMBER,
PO_TOTAL OUT NUMBER,
CUR_OUT OUT T_CURSOR
IS
BEGIN
OPEN CUR_OUT FOR
SELECT *
FROM (SELECT row_.*, ROWNUM rownum_
FROM (
SELECT column1, column2, column3 FROM TABLE1
) row_
WHERE ROWNUM <= PI_ENDID)
WHERE rownum_ >= PI_STARTID;
SELECT count(*) into PO_TOTAL FROM TABLE1;
END SP_PAGING;
END MYPACKAGE;

Yes, I can reproduce that:
SQL> create table emp1 as select * from emp
2 /
Table created.
SQL> exec dbms_stats.gather_table_stats('SCOTT','EMP1');
PL/SQL procedure successfully completed.

SQL> However, you interpreted it incorrectly. Your query will still fetch all rows in TABLE1. Optimizer is smart enough to stop creating window buffer after 9 rows and that is what you see 9 in explain plan, while my query builds 14 row window buffer and then filters. So your query will be a bit faster.

Getting the count of rows present in the oracle table

Hi all,
i want to get the total number of rows present in the sql table to the appmodule.
After applying the some view criteria to the view object. if it try with getallrowsinrange it was giving count of rows present in the viewobject but i want total number of rows present in the sql table.
How can i get that
I am using jdev 11.1.1.5
Thanks in advance

I threw something together, quick and dirty, feel free to optimize.
Assuming that you want the table count, I put the code into a EntityDefImpl subclass since this is what represents 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 type map, you might not get a oracle.jbo.domain.Number, but something else, so the cast might 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 pretty generic. You might also be able to put this into an ADF extension base class.

How to get last Record ior Total rows in For Loop Cursor ?

Hi Friends
I would like to know , the last record in for loop cursor, i have the code in following format
cursor c1 is
select * from emp;
begin
for r1 in c1 loop
v_total_rec := ? ( i would like to know total rows in the cursor , say for example if cursor has 10 rows, i want10 into this variable )
v_count := v_count +1;
dbms_output.put_line(r1.emp_name);
end loop;
end;
Hope i am clear
Any suggestions?
Thanks
Ravi

Even though cursor loops are generally a Bad Idea ^tm^ as Dan says, here's an example of how you can get the information you wanted within the query itself...
SQL> ed
Wrote file afiedt.buf
1 declare
2    cursor c1 is
3      select emp.*
4            ,count(*) over (order by empno) as cnt
5            ,count(*) over () as total_cnt
6      from emp
7      order by empno;
8 begin
9    for r1 in c1 loop
10      dbms_output.put_line(r1.ename||' - row: '||r1.cnt||' of '||r1.total_cnt);
11    end loop;
12* end;
