Number of Rows in a Tree

I think this should have a fairly simple answer, but I can't find it for the life of me. Is there somehow I can obtain the total number of rows in a tree control? With a listbox you can use the Property node "ItemNames" and just use an Array Size, but Tree Controls don't seem to have anything similair. Any ideas? Am I missing something simple?

Hi miguelc,
If nothing else miguel, this forum specifically answered how to get tree structure sizes. Happy programming.

Searchin pattern in datbase table.(Number of rows in table :More than 3 cro

Actually i have a db table having 2 columns(columnA,time).db table has 70lac rows.I have to retireve all those values which are present min. 2 times in the interval of 10 minutes for a particular value of columnA. eg. columnA,time values are

Then I have to retrieve following rows in output : {b,June-01-2011 10:14:12},{b,June-01-2011 10:15:12},{b,June-01-2011 10:17:12},{d,June-01-2011 10:18:12},{d,June-01-2011 10:25:12},{f,June-01-2011 10:39:12},{f,June-01-2011 10:43:12},{b,June-01-2011 10:51:12},{b,June-01-2011 10:53:12},{b,June-01-2011 10:56:12},{b,June-01-2011 10:57:12},{b,June-01-2011 10:58:12}
Is it related to data Mining? i have 3 crore rows in database table.I have to search such type of many patterns in my application.I have spent hours looking for tutorials on Google. However I cannot seem to find anything that holds the hand? try to be more clear, i'm in lack of ideas in this problem, even it sounds like a classic. Can oracle java data mining solve the problem?

first of all thanks for reply, i will take care of your suggestion.
Number of rows in table : More than 3*10pow7(30 Milion rows)(But it can be more than 120 milion)
Actually i have to display all those rows which setisfy following criteria:( Specific value of column A should appear min 2 times in the interval of 10 minutes.)
for eg.
eg 1. {b,June-01-2011 10:14:12},{b,June-01-2011 10:15:12},{b,June-01-2011 10:17:12}{This set is appearing 3 times in the any interval of 10 minutes.}
EG2 {a,June-01-2011 10:13:12} is present only one time,so i dont want this rows in output.
EG# {e,June-01-2011 10:26:12},{e,June-01-2011 11:38:12} is present 2 times in db,but not in the interval of 10 minutes,so i dont want this rows as output.(t1=10:26:12,t2=11:38:12 difference is more than 10 minutes.)
In my eg. i specified only 2 columns but in actual scenario there will be 8-10 columns in table.This is only one pattern which i specified,but there are many more pattern which i have to search in db.As specified above in eg. was only one pattern,After fulfiling this pattern It has to pass many other pattern.and i want result should be retrieved very fast.
Please dont go into answer of above eg.Actually i want, what should be approach of such type of problems?
Is this problem related to oracle data mining and how?
Can data mining algorthms(Minimum Description Length ,Naive Bayes,Apriori,Decision Tree,Non-Negative Matrix Factorization ,Support Vector Machine...etc..) solve my problem?
Different-2 type of queries will be fired against this table?
if i am still not clear then let me know.

Setting number of rows and columns

How do I set the number of rows and columns of a table, say 2348 rows by 3 columns?
Then how do I quickly select the last row?
Also, if I enter a formula in row 1 column 2, how do I quickly copy that formula down to row 1435, or to the end of the column? Dragging seems slow and awkward.

I wish to add a few words to Jerrold responce.

The process that you describe is inefficient.
The efficient one is :
create a table
enter the formulas in a single row
delete the rows below.
Now, each newly inserted row will contain the formulas.
From my point of view, it's when this is done that it will be interesting to apply a script adding rows.
Here is a script inserting rows.
--[SCRIPT insertRows]
Enregistrer le script en tant que Script : insertRows.scpt
déplacer le fichier ainsi créé dans le dossier
<VolumeDeDémarrage>:Users:<votreCompte>:Library:Scripts:Applications:Numbers:
Il vous faudra peut-être créer le dossier Numbers et peut-être même le dossier Applications.
Sélectionner une cellule au-dessous de laquelle vous voulez insérer des lignes.
menu Scripts > Numbers > insertRows
Le script vous demande le nombre de lignes désiré puit insère celles-ci.
--=====
L'aide du Finder explique:
L'Utilitaire AppleScript permet d'activer le Menu des scripts :
Ouvrez l'Utilitaire AppleScript situé dans le dossier Applications/AppleScript.
Cochez la case "Afficher le menu des scripts dans la barre de menus".
--=====
Save the script as a Script: insertRows.scpt
Move the newly created file into the folder:
<startup Volume>:Users:<yourAccount>:Library:Scripts:Applications:Numbers:
Maybe you would have to create the folder Numbers and even the folder Applications by yourself.
Select a cell below which you want to insert rows.
menu Scripts > Numbers > insertRows
The script ask you the number of rows to insert then it does the required insertion.
--=====
The Finder's Help explains:
To make the Script menu appear:
Open the AppleScript utility located in Applications/AppleScript.
Select the "Show Script Menu in menu bar" checkbox.
Save this script as a … Script in the "Folder Actions Scripts" folder

How To Restrict Number Of Rows For Multiple Group In Report Output

Hi ,
I have a requirement to restrict number of rows in report output.I have three different group , if i use same no of rows to restrict then output is as expected but if i want Deduction group should have 7 rows , earning should have 5 rows and Tax group have 3 rows in report output then XML tag is not working.
Below is the XML tag i am using -
First i have declare the variable to restrict the rows -
<xsl:variable name="lpp" select="number(7)"/>
<xsl:variable name="lpp1" select="number(5)"/>
<xsl:variable name="lpp2" select="number(3)"/>
For Each -
<?for-each:PAYSLIP?>
<xsl:variable xdofo:ctx="incontext" name="DedLines" select=".//AC_DEDUCTIONS"/>
<xsl:variable xdofo:ctx="incontext" name="EarLines" select=".//AC_EARNINGS[ELEMENT_CLASSIFICATION!='Taxable Benefits']"/>
<xsl:variable xdofo:ctx="incontext" name="EarTaxLines" select=".//AC_EARNINGS[ELEMENT_CLASSIFICATION='Taxable Benefits']>
<?for-each:$DedLines?><?if:(position()-1) mod $lpp=0?> <xsl:variable name="start" xdofo:ctx="incontext" select="position()"/>
<?if:(position()-1) mod $lpp1=0?><xsl:variable name="start1" xdofo:ctx="incontext" select="position()"/
<?if:(position()-1) mod $lpp2=0?><xsl:variable name="start2" xdofo:ctx="incontext" select="position()"/>
Report output is tabular form (one page has two column - Earning and Deduction ) . Tax group comes below earning group.
Deduction Group -
<?for-each-group:$DedLines;./REPORTING_NAME?><?if:position()>=$start and position()<$start+$lpp?>
<?REPORTING_NAME?>
<?end if?><?end for-each-group?>
Earning Group -
<?for-each-group:$EarLines;./REPORTING_NAME?><?if:position()>=$start1 and position()<$start1+$lpp1?>
<?REPORTING_NAME?>
<?end if?><?end for-each-group?>
Tax Group -
<?for-each-group:$EarTaxLines;./REPORTING_NAME?><?if:position()>=$start2 and position()<$start2+$lpp2?>
<?REPORTING_NAME?>
<?end if?><?end for-each-group?>
Please let me know in case additional detail is require.
Thanks in Advance.
Thanks,
Harsh

variable lpp2 is declare to restrict EarTaxLines -
<xsl:variable name="lpp2" select="number(2)"/>
This will help to restrict the no of rows on one page , if we have more then two tax benefits line then layout will roll over to continuation page.
As part of report output my expectation is if i restrict Earning , Deduction and Tax benefits to same no of line for example - variable lpp ,lpp1 and lpp2 have same value "number(2)" , we can see the layout is continue on next page (restrict every group can have max two lines) .This is the reason we have 4 header grid , deduction and Tax Benefit lines are rolled over to continuation page .But if we restrict different value for each variable then continuation page layout is missing .
When we tried for <xsl:variable name="lpp2" select="number(3)"/> value continuation page layout is not getting generate for both employee number .

How to set the number of rows displayed in a classical report at runtime?

Hi,
Our customer has several standard client hardware configuration and would like to enable end users to choose their 'display profile' at login time. This 'display profile' would contain predefined values for these hardware configurations and supposed to set various paramters that should define the number of rows displayed in a classical report region.
I tried to provide parameters on the report region but it refused to accept anything but numerical values. Is it possible to do this?
Regards, Tamas

The link is to the closest linkable point in the documentation to the description of the Number of Rows (Item) attribute.
It sounds like you have been trying to enter—unsuccessfully—an item name or substitution string into the Number of Rows attribute. The Number of Rows (Item) attribute is the one that actually allows you to do this. Click on the flashlight icon beside it to get a list of items from the application.

About the number of rows used to map data in Xcelsius

Hi Everyone:
I am using web services to fetch data into Xcelsius. The information I got from web service will increase in time and what I suppose is when I run out of rows to get all data I must open my Xcelsius model and select a greater range of rows on each component to get all the data that the web service is bringing.
Is there an alternative to avoid modifying ranges of data in crontrollers when rows mapped are not enough for the data you are fetching from a web service?
It is a bit confusing, I hope I've been clear enough. I really really will appreciate your opinions. If possible give me technical explanations.
Thank you,
Skull
Edited by: skull_buck on Aug 6, 2009 7:40 PM

Hi Greg
Thanks for your fast reply.
What you suggested is exactly what I am doing now, and also I increased the number of rows allowed to map en Xcelsius which are 512 by default.
I would like to know now, how many rows are advisable to increase? Because I am using some components and you must specify for each one a certain number of rows.
I test mapping 3000 and even 6000 rows but the model is too slow and I was not able to export the swf file in any format.
Thank you again,

Number of Rows Displayed in a SQL Report Region

Hi,
Just wondering whether it is possible to control the 'Number of Rows' displayed under the 'Layout and Pagination' section within the Report Attributes page.
Basically need to know if I can programmatically control this or even better, can it be customized by the user as the user may want to see say 15 rows, 200 rows or 'All' rows of a certain region on the page. FYI, I have three different report regions on one page and want to give the user the flexibility to modify the number of rows displayed per region.
Thanks.
Tony.

Merging two separate Tables into One - different number of rows

Hi. I have a problem. Oracle 10.2.0.4.0
7 years ago when i was learning how to query my teacher told me that is possible to creata some kind of report where results could be combined in 1 view(report) witch in different variable could have different number of rows.
I just remember that there is needed to use group by function and some join?
Please help
In link there is a sample sample view
I need to combine Table A using D variable with Table B to become Wynik(result)
Tables create
CREATE TABLE "TABELA_A" ( A NUMBER,B NUMBER,C NUMBER,D NUMBER ) ;
INSERT INTO "TABELA_A" (A, B, C, D) VALUES (123, 1, 70, 999)
INSERT INTO "TABELA_A" (A, B, C, D) VALUES (123, 2, 80, 999)
INSERT INTO "TABELA_A" (A, B, C, D) VALUES (234, 1, 100, 111)
INSERT INTO "TABELA_A" (A, B, C, D) VALUES (456, 1, 10, 222)
CREATE TABLE "TABELA_B" ( D NUMBER,E VARCHAR2(255),F NUMBER ) ;

How to limit the number of rows in a report

I have several reports with a number of parameters - date ranges etc.
Depending on the parameter values selected by the user the reports can return thousands of rows.
I would like to limit the number of rows returned to, say, 500. If more than 500 rows are returned by the query then display an error message requesting that the user enter more specific parameters.
Ideally for performance reasons it would be good to catch the error before the datafile is generated, but I don't know if this is possible. Alternatively a check in the template might do the job - using COUNT on the group?.

Hi Hugh,
In your query, you got to add rowum < 500 or some sort of DB specific limit to the row being returned,
this will help to stop the report to get more than 500 records and the report template wont have any restriction.
or
you can do that in template too, but i would not recommend.
In these both cases or in any case, you cannot give any meaningful error if it exceeds N rows,there is no option like this till now.

Different number of rows for different columns in JTable

hi
I need to create a JTable with different number of rows for different columns...
Also the rowheight should be different in each column...
say there is a JTable with 2 columns... Col1 having 5 rows and column 2 having 2 rows...
The rowHeight in Col2 should be an integer multiple of Rowheight in Col1
how do I do this ??
can anybody send me some sample code ?????
thanx in advance

How about nesting JTables with 1 row and many columns in a JTable with 1 column and many rows.
Or you could leave the extra columns null/blank.
You could use a GridBagLayout and put a panel in each group of cells and not use JTable at all.
It would help if you were more specific about how you wanted it to appear and behave.

How to get number of rows

Hi!
Can someone tell me how to obtain the number of rows returned by a query?
I tried to use getFetchSize() but it seems to always return 0 for my query.
THANKS in advance!
ResultSet testRS = Stmt.executeQuery(testStmt);
int size = testRS.getFetchSize();
System.out.println("size = " + size);
Wo Lay

To get the number of rows returned, you have to loop
through the result set, or do a "select count" (which
is more efficient since it doesn't have to pass the
rows across the network) ...Looping around the entire result set is not very performance efficient. Then agin if you use count (*) you actually execute an extra query.
The best thing you can do is:// assume res is your result set.
res.last();
int rows = res.getRow();This way you only have to execute one query and you don't really need to loop around the entire result set. Of course you will have to have a scrollable result set, if this is supported by your DB.
Hope that helped.

Hi,
Initialise one variable TOT_ROWS to 0.
Then in the for loop
tot_rows := tot_rows + +1 ;
so after for loop the value in the tot_rows will be the total records..
If u want it to get this value in the calling procedure of this , just declare tot_rows parameter as out parameter.
For sum of a column:
Initialise a variable sum_col to 0.
In the for loop
sum_col := sum_col+I_info.column_name
aprameter if u wish return this value as out..
I think this wil give u the o/p..
cheers,

How to get number of rows and columns in a two dimensional array ?

Hello,
What would be the simplest way to get number of rows and columns in a two dimensional array represented as integers ?
I'm looking for another solution as For...Each loop in case of large arrays.

How to get number of rows return in SELECT query

i'm very new in java, i have a question:
- How to get number of rows return in SELECT query?
(i use SQL Server 2000 Driver for JDBC and everything are done, i only want to know problems above)
Thanks.

make the result set scroll insensitve, do rs.last(), get the row num, and call rs.beforeFirst(), then you can process the result set like you currently do.
         String sql = "select * from testing";
         PreparedStatement ps =
          con.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
         ResultSet rs = ps.executeQuery();
         rs.last();
         System.out.println("Row count = " + rs.getRow());
         rs.beforeFirst();~Tim
NOTE: Ugly, but does the trick.
