Count of rows of a table in header

Hi Experts,
I am stuck in a tricky scenario.
I need to get the count of rows of a table in a webi report in the header of the report.
And the count should change dynamically according to the filtering done on the table.
For eg.
If I have 10 countries in a table, so table has 10 rows.
Now the count on header should show 10.
Now if we filter the column to 5 countries, the count on the header should change to 5.
Any Idea's.
Regards,
Gaurav

Nops
It doesn't work.
Let me reframe my issue again:
I dragged country object on my report.
UK
US
JAPAN
CANADA
Now lets say in the report title, I write the formula as =Count(country)
It will give me 4.
Now I clicked on the column country and applied filter i.e. country = US ; UK
Now the block shows
UK
US
In the header the cell still shows 4, which I want to see as 2.
Any ideas....?
Thanks
Gaurav

How to get count of rows for a table?

Hi,
How to get count of rows for a table and secondly, how can i have access to a particular cell in a table?
Regards,
Devashish

Hi Devashish,
WdContext.node<Your_node_name>().size() will give you the no: of rows.
This should be the node that is bound to the table's datasource property.
WdContext.node<Your_node_name>().get<node_name>ElementAt(index_value); will select the row at that particular index.
You can access an attribute of a particular row as
WdContext.node<Your_node_name>().get<node_name>ElementAt(index_value).get<attribute_name>();
Hope this helps,
Best Regards,
Nibu.

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

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 number rows in multiple tables from one query

Hi
I was wondering if its possible to have a single query return the number of lines in multiple tables, for example i have the tables
foo1
pk_foo1
and
foo2
pk_foo2
They are not joined together by any contraints. So the pseudo code for the query would be something like
SELECT numrows(pk_foo1), numrows(pk_foo2) FROM foo1, foo2
Thanks!

without a join you get a cartesian product for the query:
SQL> select count(d.deptno),count(e.deptno)
2 from dept d,emp e
3 /
COUNT(D.DEPTNO) COUNT(E.DEPTNO)
            105             105so you need to do a bit of trickery
1 select a.cnt,b.cnt
2 from
3 ( select count(d.deptno) cnt from dept d ) a,
4* ( select count(e.deptno) cnt from emp e) b
SQL> /
       CNT        CNT
         7         15
SQL> select count(*) from dept;
COUNT(*)
         7
SQL> select count(*) from emp;
COUNT(*)
        15

Howto limit max. count of rows in a TABLES-based import-parameter?

Hello all,
I have created a web service based on a custom function module in SAP. Beside others this function module provides one TABLES input parameter, which is set to "optional". Now I want to publish the web service with this parameter optionally as well, but also allow it for max. 10 tmes (meaning max. 10 rows for this import table).
I have found an entry for min and max settings in SE80 for this web service, but unfortunately these both fields are read-only, so I can't set the maxOccurs here.
Any ideas how I can solve this problem?
Thanks in advance for your help!
Kind regards, Matthias
Edited by: Matthias F. Brandstetter on Oct 21, 2010 10:32 AM

Hi,
It is not possible to change SAP generated service. Better you create new service in ESR and assign correct maxOccurs and then create proxy of this service in backend where you can also map ESR service to FM.
To minimize effort you can copy same wsdl and then change wsdl and import in ESR as new service.

have some one a sample script or query for exaple;

But from the subject line I could read as you like to know the record count of all tables in a schema.

Re: RECORDS COUNT

Count rows in a table being retrieved from dba_segments

Hello guys,
I was wondering how can I count the rows in a table that is being retrieved from dba_segments.
-- I am getting the table name from dba_segment
-- Is it possible to count the number of rows in that table at the same time?
-- If not, is there an alternative step without analyzing the table or schema, then getting the result from num_rows in all_tables?
I want the count code to add to the select statement..
SELECT owner, segment_name , segment_type, partition_name, bytes
FROM   dba_segments
WHERE owner = UPPER( v_schema )
ORDER BY segment_name;I try to add this to the select statement. count(segment_name), but that did not work.
Any direction(s)?

Count of Rows - Meaure

Hi There,
I am trying to create a measure in cube browser which will return count of rows of a table. If there are some rows, it returns correct result but in other case if table is empty, it returns nothing.
I want to return 0 in later case.
Please advise.

You could create a Measure with code. Something like this, it is made in AdventureWorks2014.
CREATE MEMBER CurrentCube.Measures.[Count Rows Dimension] AS
CoalesceEmpty(COUNT([Customer].[Customer].[Customer]),0),
Associated_Measure_Group = 'Measure Group you want it associated to';

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?

Count of records/rows in a Table

Hi
This could be a basic question , but i don't have an idea how to do that .
Could you please tell me , how get an count of records/rows in a specific table ?
Thank you

If it takes you longer to count many things, why do you expect Oracle to do better than you?Really??
Let's try some counts and see.
First off, let's count a few 1000 rows.
SQL> set timing on
SQL> select count(*) from all_objects;
COUNT(*)
45045
Elapsed: 00:00:17.08So 17 seconds for 45,000 rows.
Now if you're logic is correct, counting let's say a few billion rows, should take an hour? Perhaps more?
Here's what I see on one of my larger tables:
SQL> select count(*) from daily_xxxxxxx;
COUNT(*)
2569780329
Elapsed: 00:00:10.03Oops... it is faster.
Get a clue!I hereby sincerely apologise that my database does not adhere to your fine logic that says it should take a few hours - I will speak disapprovingly to the CBO for allowing the 2nd select count (on the same database) to be faster than the 1st select count. I will even use the backchannel to inform Larry that this is not acceptable.
Of course, this is assuming that you do not have your head stuck up somewhere and are indeed correct that it takes a "+looooonnngggg+" time to count lots of rows.
