No Count all Rows in Discover Plus

Hello,
in Discoverer Desktop it is possible to count all rows (menue: sheet|Count all Rows) for a query. In Discoverer Plus Version 9.0.4 i am missing this feature. Is there a work around for this problem?
Franz

Thanks Marcus,
i know, but it is a very slow way if you are selecting 10000 records. I don't understand why Oracle is not be able do add this feature like in the Desktop to Plus.

'Count all rows' in Disco Plus?

Hi all - I can't find an option to Count All Rows in disco plus. This is something my users use all the time in Desktop - is it included in Plus?
In Desktop, it is under menu item 'Sheet'
Thanks!
Scott

Hi Scott
Sorry that was removed from Discoverer Plus so you won't find a button for it. Having that there would force Discoverer to have to run the entire query just to give you the total count. Oracle considered this a waste of resource and query effort, which I sort of agree with because I can see what they are getting at, and so removed it.
Best wishes

Count all rows in all tables

Is there any easy way to count all of the rows in all of the tables?
I am currently generating a list of tables by selecting from all_tables and then turning that into individual select count(*) statements using awk.
I'm guessing there is probably some other better method?

Jim,
I have a sql script which I call numrows that will dynamically create select count(*) statements from the dba_tables dictionary view... It does not display all of the tables in the entire database, but instead prompts you for a particular schema. Maybe you can adjust to do what you want it to..
Regards,
David

Count ALL rows in databases

Hi experts!
I need the total number of ROWS in EACH database i have (All schema)
I've tried this for each DB
select sum(num_rows)
from sys.dba_tables
where owner like '%%'
i obtain the number of all rows for all schema in database.
I have many database, i use agent g10.0 and enterprice manager to query them.
I
've seen that in Enterprise Manager, when you select a Database Istance, then go on "administration" tab, and u click on TABLES link, you can see number of rows and last time the table was analyzed. How are they have been calculated? With table dba_tables? How can i query to obtain these values?
I know it's a stupid task but my boss wants this info :(

> I know it's a stupid task but my boss wants this info :(
Tell him two gazillion. Also tell him that the gazillion scale has been specifically created for managers like him with heads firmly stuck up the back side.
Anyway, here's some sample code. Note that you cannot use DBA_TABLES view. Object tables are not listed in there and they can contain rows (obviously). There is also the case of dealing with case and "weirdly" names tables - thus double quotes are needed.
I only did the first 10 tables.. It is stupid to just one, never mind all of them in database...

Count all rows of a Database table

I want to count all the rows of a table.
I have made correctly the connection with the database and all the other things (make a statement, make the query and the resultSet), I use the MySQL server v4.0.17
Here is the code I use:
int count=0;
String temp=null;
String query = "SELECT COUNT(*) FROM customers";//customers is my Database Table
try {
rs = stmt.executeQuery(query);
}//end try
catch(Exception exc) {
createFeatures.PlayErrorSound(registerRenter);
Optionpane.showMessageDialog(registerRenter,
"MESSAGE", "ERROR", JOptionPane.ERROR_MESSAGE);
}//end catch
try {
while(rs.next()) {
count++; //I use this variable in order to count the rows because the resultSet doesn't tell me the answer
countLine=rs.getInt(1);
}//end while
}//end try
catch(Exception exc) {
createFeatures.PlayErrorSound(registerRenter);
Optionpane.showMessageDialog(registerRenter,
"MESSAGE", "ERROR", JOptionPane.ERROR_MESSAGE);
}//end catch
count=count++; //i increase it aggain because if the rows are initial 0 i want to make it 1
temp = String.valueOf(count);//i use this command in order to display the result into a jtextfield
Any help is appreciated!!!!!

Calculating a count of rows where value matches another column value in the same table

Hi,
I'm struggling to do something in DAX that seems to me should be super easy (coming from a SQL world)!
That is to count all rows in column 1 where the value matches the current value for column 1?
E.g something like this:
[Col2]=Count of rows in [Col1] where value = this.[Col1]
Where the results are as in the table below:
Col1, Col2
A, 2
A, 2
B, 1
Anyone?

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:
<br><b>Total Number of Results:</b> #TOTAL_ROWS#.</br>
why can't i use #TOTAL_ROWS# as a template variable? and how can i do that?

View all rows

Hi,
I want to view all rows of a workbook in Discoverer Desktop but I can't. I have a worksheet where I can view 10000 rows. But when I select Sheet --> Count all rows the answer is 83165.
How can I view the rest of rows? I have the Sheet --> View all rows option disabled.
Thanks.

Hi there,
Look at Tools-->Options-->Query Governor. The "Limit retrieved date to" is set to 10,000. Change as required or de-select the option.

Need Query to that generate count of rows of all tables

Hi
i need a query which gives the result of no.of rows in talbe and coresponding table name.
And then i need to compare the same with other DB schema
Thanks in advance

Hi User,
We can also get the count of rows for all the tables associated with a User, we can create a custom function which
uses the table name to return results.
CREATE OR REPLACE FUNCTION TAB_ROWS_CNT (TAB_NAME IN VARCHAR2)
   RETURN NUMBER
AS
   TAB_CNT   NUMBER :=0;
BEGIN
   EXECUTE IMMEDIATE 'select count(*) from ' || TAB_NAME
      INTO TAB_CNT;
   RETURN TAB_CNT;
END;And query,
SELECT TABLE_NAME, TAB_ROWS_CNT (TABLE_NAME) ROW_CNT
FROM USER_TABLES;Which gets us the count of Individual Tables for a user.
This is an just that we can do in this way also. But, use which is optimal.
Thanks,
Shankar

Query to return ALL rows even those with zero counts

Hi,
The following query will return only those rows that have a non zero count value:
select c.id, a.name, count(*) as XYZ from CON c, CUST a
where c.help !='1' and (c.id = a.id) group by c.id, a.name order by c.id;
The results are:
1 ME 3
3 YOU 4
What i want is to return all rows in CUST and the count, XYZ, that correspond to each row in CUST that matches the whare condition above, even if the count is zero.
ie
1 ME 3
2 WE 0
3 YOU 4
Can this be done?

You may want to get the counts then do the outer join. If you simply count with an outer join you will get 1 for 'WE' because there is a row in the cust table with 'WE'. This may work for you;
with
cust as (
   select 1 id, 'ME' name from dual union all
   select 2 id, 'YOU' name from dual union all
   select 3 id, 'WE' name from dual),
con as (
   select 1 id, '2' help from dual union all
   select 1 id, '2' help from dual union all
   select 1 id, '2' help from dual union all
   select 2 id, '2' help from dual union all
   select 2 id, '2' help from dual union all
   select 2 id, '2' help from dual union all
   select 2 id, '2' help from dual)
-- end of test data
select a.id, a.name, nvl(c.cnt,0) xyz
from cust a,
   (select id, help, count(*) cnt
   from con
   where help !='1'
   group by id, help) c
where a.id = c.id(+)

Procudure to count all the rows in a all tables in the schema

When I run the following store procedure to count all the rows in all the tables I crash my sql Plus editor:

     END;
END LOOP;
END;
What am I doing wrong.
Thanks for any help Tony

The boss gave me 5 pages of tables and wants to know how many row there are in each table. There is a problem of one DB being out of sync with another.
But I have managed to work the problem though.
here is the working code:
CREATE OR REPLACE PROCEDURE TC_TABLEROWCOUNT (
TableOwner IN varchar2)
IS
row_count number;
vTable varchar2(30);
v_sqlstmt varchar2(100);
cursor get_tab is
select table_name, num_rows
from all_tables
where owner = TableOwner;
begin
dbms_output.put_line('Checking Record Counts for schema maxdev ');
FOR get_tab_rec IN get_tab LOOP
vTable := get_tab_rec.table_name;
v_sqlstmt := 'SELECT count(*) from '||vTable;
EXECUTE IMMEDIATE v_sqlstmt into row_count;
dbms_output.put_line('Table '|| get_tab_rec.table_name || ' Row ' || row_count);
END LOOP;
END;

How to get all rows of an attribute data from a table?

Hello.. I´m using Jdev 10.1.3.2
I have a table with 5 columns and N rows.
I need to create a backing bean method to count the value of all rows of a specifc column.
I use
JUCtrlValueBindingRef selectedRowData= (JUCtrlValueBindingRef)myTable().getSelectedRowData();
to get an attribute from a selected row. but How can get from all rows?
Thank you
Vandré

Hi Vandré
I think this example of Steve Muench will help you.
"Recalc Sum of Salary at the View Object Level
This example illustrates a technique where a transient attribute of a view object is updated to reflect the total sum of some attribute of all the rows in the view object's default row set. The code to recalculate the sum of the salary is in the getSumOfSal() method in the EmpViewImpl.java class. The custom EmpViewRowImpl.java class for the view row implements the getter method for the SumOfSal attribute by delegating to this view object method. The EmpViewImpl class extends a base DeclarativeRecalculatingViewObjectImpl class that contains some generic code to enable declaratively indicating that one attribute's change should recalculate one or more other attributes. The EmpView defines the "Recalc_Sal" property to leverage this mechanism to recalculate the "SumOfSal" attribute. If you restrict the VO's results using the BC Tester tool, you'll see the sum of the salaries reflects the subset. If you add a new row or delete an existing row, the sum of sal is updated, too."

Cannot get all rows from cfProcResult

We upgraded one of our servers (A) from CF 6 to 7.02. Another
server (B) has CF 7.01.
On server B (CF 7.01) the code works (below), all rows of
each dataset are returned.
Now on server A (CF 7.02) all of the resulting datasets have
only the first record in them. If I add maxrows="-1" to each of the
cfProcResult tags there is no change. If I change that to
maxrows="100" then I can get the rows up to 100.
Is this a bug or is there a different means to return all
rows?

It think its a bug. I got the same results under MX 7.0.2.
The topic of maxrows recently came up on another thread. I
did some searching and according to TechNote 18339 there was a
change with maxrow
"<cfquery maxrows=N> bug. ColdFusion MX (until ColdFusion
MX 7.0.1 CHF2) didn't pass maxrows to the underlying driver
(statement.setMaxRows())"
Given the results you're getting, it sounds like CF is
applying the maxrow to all of the resultsets, not just the one
where maxrows was declared. I suspect cfstoredproc's usage of
statement.setMaxRows() is incorrect. Thats just a guess though.
Bottom line, I think you'll need handle it manually.
Personally, I would recommend placing the row count logic in the
stored procedure (if possible). The overall results will be more
consistent and you won't have to worry about this kind of issue
again.

Report Region show all rows?

Hi,
I have a report region in which I want to show all rows. Setting the pagination scheme to No Pagination doesn't
seem to do the trick. I have set Number of Rows and Maximum Row Count both to NULL. Nothing seems to work.
Is there some trick to get all rows to be displayed?
Thanks in advance!

Hi,
I have two report regions on different pages. On both I have set 'Number of Rows' and 'Maximum Row Count' to null. One report will return all the records in a query (~800), the other report will only return 500. I can't see any other differences in the reports that would cause this behaviour.
I didn't really want to restrict my reports to a set number of rows, is this really the only option?
Thanks,
Rochelle.
