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

Hi Nutan,
Marcel is right about backend. However I might have an idea once I am developing a quiet similar solution. I would like to ask you to explain with more detail. It seems you have two requirements in one question.

Counting the rows

Hi,
I've a datamodel with BI Query. I want count the rows like a rownum function. How can I do this?
Thanks R.
Edited by: user12003776 on Jan 26, 2012 5:02 PM

Do you want to get a count of rows in the query or do you want to find the count in the template? Rownum function returns the rows' position.
If you want to find the count of rows within the template for some conditionally formatting, then you could use something similar to this:
<?count(/XXTA_SHIP_LABEL/LIST_G_CUSTOMER/G_CUSTOMER)?> -- change the path to the field in your dataset
Can you explain a bit more as to what you are trying to do?
Thanks,

Does anyone know how to remove the separator in AddRemove List component?

I tried many things but none seem to work. I tried
addRemoveList1.setSeparators(false) and this didn't do anything. Our UI Designer does not like the separator to be at the bottom of both list boxes, so is there a way to make it disappear. I don't think there are any facets on the separator.
Thanks

Is it possible to count the rows returned from a query?

Hello,
When using JDBC is there anyway of finding out the number of
rows returned from a query before actually getting each row?
In Forms 4.5 you can use the count_query function, does anyone
know of an equivalent function or work around in JDBC and/or
SQLJ?
Thanks.

Thanks for the advice, I'm currently using SELECT COUNT(*) but
I'm looking for a more efficient way of doing it. If I SELECT
COUNT each time then I have to prepare and execute a SQL
statement each time. What I want to do it execute a single SQL
statement to return my results and somehow find out the number
of rows in the resultset without having to go back to the
database.

How do i count the rows??

hello,
i have a database from where I import a table.
now, because of my data-structure i need to know the nubmers of row in my table.
For that i don't want to use the sql-statement: select count(*) ....
but instead I want to use a java JDBC function. I looked at the docu, but i wasn't able to find it.
Can somebody help me please?
thanks

Why not use an ArrayList and simply add
each record as you fetch it -- then you don't
need foreknowledge of how many you fetched.

Counting the rows in a ResultSet

I am wondering how I could find out the number of rows in a ResultSet after performing a query?

In case anyone's curious I figured out the problem. The ResultSet needs to be set to move forward AND backward. This is done as follows:
Statement stmt = conn.createStatement(
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);

Empty Line at the End of a List Component

I am using a list compenent in which I am manually adding
items to it (i.e. addItemAt). The list is long enough to be
scrollable. At the end of the list is a blank line, or a space big
enough to look like the size of a line. It is not clickable or you
can't highlight it if you click but it is there and looks a little
funny.
Does anyone know what is creating this and how to get rid of
it?
Thank you.
Dave

Pretty much you are creating this... Are you iterating an
array to populate
the list, and not stopping soon enough? Remember arrays are 0
index based,
you you want to go to < the length, not <= the length.

Perhaps this

     group by cert_no having count(distinct RACE_CODE) > 0 )
b as (
     SELECT cert_no, count(distinct RACE_CODE) RACE_CODES FROM med_subscriber
     group by cert_no having count(distinct RACE_CODE) > 0 )
c as (
     select cert_no, count(distinct RACE_CODE) RACE_CODES from den_subscriber
     group by cert_no having count(distinct RACE_CODE) > 0 )
select cert_no, a.race_codes + b.race_codes||' (in med_subscriber and subscriber tables)'
        ||' , '|| c.race_codes ||' (in den_subscriber table).' col1
from a , b , c

Count the number of rows based on the values!!!

Hi all,
What I am using:
I am working with a multidimensional database in Visual Studio 2010 using its Data source view and calculation member and dimension usage.
What I want to do:
I have a fact table that has five columns(leg(s),hand(s), Head and body,overall) that shows the category of how severe the injury is. Let say for the records all columns never have an empty value(no injury is stated with 'No injury' ) . These five columns
are connected with a dimension that has all the available values (Category A-E of injury).The overall has the most severe from the other four columns. I want to create a bar chart with five different measure
values, one for each column, and count the values in those columns.
For example : I have a slicer in the excel and a bar chart and the slicer has all the values of the Category of the injury ( Cat a,Cat B, Cat C, ... Cat E, No injury ) and when i select one of them, lets say
Cat C, the bar chart should update and show how many Cat C each measurement column has.
Example FACT table:
ID LEG HAND HEAD BODY OVERALL
1 No A No No A
2 No D C C C
3 E C D A A
4 E E B C B
So if i selected C the bar chart will count (Leg = 0, Hand = 1, Head = 1, body = 2 and Overall = 1).
Any ideas ?
Thanks for the help and the time :)

Hi DBtheoN,
According to your description, you want to create a chart on excel worksheet to count the rows based on the value, right? If in this case, I am afraid this issue is related to Office forum, I am not the expert of Office, you can post the issue on the corresponding
forum.
However, this requirement can be done easily on SQL Server Reporting Services. You can using the expression below to count the rows.
=COUNT(IIF(Fields!LEG.Value=Parameters!TYPE.Value,1,NOTHING))

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.

List Component Links

I have created AS3 script for loading and parsing an RSS
feed. I have successfully displayed the "title" node on the stage
in a List Component with the instance name "blogList". Now I wish
to use the corresponding "Link" node so that each item in the list
will open a web page to the link for that story. I have been able
to get each title to link to the last URL link in the RSS feed. I
am stumped. Help :)

Answer from the boys at actionscript.org.
Works like a charm. The function for click is outside of the
function blogLoaded and most importantly used the data property on
the object in order to pass the correct reference.
var blogLoader:URLLoader = new URLLoader();
var blogURL:URLRequest = new URLRequest("
http://www.canada.com/calgaryherald/topstories.rss");
blogLoader.addEventListener(Event.COMPLETE, blogLoaded);
blogLoader.load(blogURL);
var blogXML:XML = new XML();
blogXML.ignoreWhitespace = true;
function blogLoaded(evt:Event):void {
blogXML = XML(blogLoader.data);
//trace(blogXML);
for(var item:String in blogXML.channel.item) {
blogList.addItem({label:blogXML.channel.item[item].title,data:blogXML.channel.item[item]} );
blogList.addEventListener(MouseEvent.CLICK, blogClick);
