Measure to count of rows in a calculation part of cube

Hi All,
Is it possible to create measure which shows me number of rows in a fact table?
I'd like to create it using mdx syntax (in a query using WITH MEMBER [Measures].[Count]). Unfortunately, I can't modify cube definition, so I have to use mdx syntax in a query...

Hi,
In your Visual Studio project locate the target fact table in data source view (DSV file) and create a "Named Calculation" (Right-click the target fact table on DSV and select "New Named Calculation..." option) and hard-code 1 in the
expression dialogue. Then use the newly created column name along with the Sum function to create a cube level measure.
Here is a screenshot.
Best regards,
Chandima

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?

Thanks, that's perfect!
I knew it had to be something so simple, but after spending over an hour banging my head against those exact functions I couldn't get anything working!

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';

Count of rows from different tables.

Hi Friends,
I have 4 tables with a common column name "ID". I would like to get the count of rows from all the four tables which has the same ID.
Ex
select count(a.id) from table1 a,table2 b,table3 c,table4 d where a.id=b.id=c.id=d.id=5;
please suggest me some solution

may be thsi?
select count(a.id) from table1 a,table2 b,table3 c,table4 d
where a.id=b.id and a.id=c.id and a.id=d.id and a.id=5;

Count the rows in a list-component

Hi,
How can I count the rows with a value in a list component?
I thought it would be RowCount but as I figured out that shows the number of shown rows, not the number of rows with a value.

Hi,
Try list.dataProvider.length

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.

Use timing measured using counter 1 to set the pulse width on counter 2

I am measuring time between 2 edges on counter 1. I want to be able to generate a pulse on counter 2 that is dependent on the time measured by counter 1. The delay on counter 2 is a multiplicative of the time measured on counter 1. Is this even possible?

Hi Thaison V,
I am using a PCI 6251 M series card and using DAQMX. Your assumptions are alomost correct. I am using a period measurement to measure time in between two leading edges on counter 1 inside a while loop. I had set up the second counter to generate a single pulse on each trigger (retriggerable digital trigger) inside the same loop and update the low time of the pulse using the channel property. There seems to be a 2 iteration delay between when counter 2 catches up with time measured on counter 1 time. I believe this is because the pulse is already generated before the vaule is measured on counter 1. I suppose if I can use counter write after the counter 1 is read out it might work, but I haven't figured out how to use DAQMX write to write a single pulse ( it works only for pulse train??).
thanks for your help

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!!!!!

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.
Thanks

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.

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

ABAP WD: Count of rows using display_type_hierarchy in ALV

Hi,
I am trying to implement display_type_hierarchy in ALV and my requirement is to change the hierarchy based on user selection.
I am able to get the hierarchy based on user selection. For ex: If there are 3 columns in ALV then user can choose the column in a dropdown box and see the hierarchy based on the chosen column. But I want to get the count of rows inside the hierarchy. I did not find any standard method for this. (Is there one?) Could you please let me know how to do it?
Regards,
Srini.

G'day Anett,
Did you manage to get an answer to this issue, we are trying to do the same thing.
Cheers,
Mick.

Sqlldr; restrict count of rows

How can I restrict the count of rows to load.
The skip option allows to skip the first rows, but how can I stop if a defined count of rows is loaded?
I need that for testing
Thanks for your help.
Frank

I have to use to original data in my test case and can not modify the input file.
I like to restrict the count of loaded rows in the control file.
