Count the number of rows in an array

Hi there,
I'm quite new with Labview, maybe somebody can help me.
I have a .vi that controls two pump with certain ratios (to make a composition gradient). I export the data to an ascii file, which write the displacement of the two pumps in 2 colums. However, the number of rows is related to the ms-counter, and thus related to the processor of the computer. Now I need, at the end of the vi, to get the number of rows written to the ascii file, to do some further calculations. Does anybody know how to do this?!
Thanks

You could wire the loop-counter to a variable outside the loop, so you can see the number of iterations (don't forget to add 1).
You also can use the Array Size-Function. Here you get different outputs, according to the dimensions of the array to get the size of.
Here you can see what you get if you use this function:
1D-Array: one value
2D-Array: array, item 0 = number of rows, item 1 = number of columns
3D-Array: array, item 0 = number of pages, item 1 = number of rows, item 2 = number of columns
So if (in your case) you wire a 2D-Array you can use the array-size function, select item 0 of the array you get and you get the number of rows.
You can also have a look at the attachement.
Hope it helps.

How to count the number of rows in a resultser object?

hi there
how to count the number of rows in a resultser object which may contains millions of rows? besides using a while loop? thanks

You don't, you execute a query whose result is the record count of those records that match the search and then you execute the actual query to create your record set. Typically you do
select count(id) from YourTable where [filter]
from the resulting ResultSet do
int res.getInt(1);
which gives you the count and then
select id from YourTable where [filter]
to produce the actual result set.
in the second query the id part can be substituted with the actual fields you want.

Count the Number of Rows in Data form

Hi,
I want to count the number of rows in a data form.In my form there is a large number of rows.Is there any way to count it.
Thanks.

If you are on 11.1.2.x then you could look at adding a formula and using the CountA function - http://download.oracle.com/docs/cd/E17236_01/epm.1112/hp_admin/apcs03s06.html
Otherwise it would be possible using custom javascript which you would have to had some experience in using.

Count the number of rows in a workbook.

Hi Experts , I have a requirement to count the number of rows in a WorkBook.Will it be possible to do this by creating a KeyFigure?Or are there any options in BEx to count and display the number of Rows.Many thanks for all your help.

Hi
In the query create a calculated key figure called 'Count' and put a formula as =1, then use this count where ever applicable..you can very well count the no. of rec.
with this.
Hope this helps..
assign points if useful..

How to count the number of Rows to be Updated before Update takes place..

Hi all,
I have a requirement, where i have to count the number of rows to be updated before updating it. SQL%ROWCOUNT gives the no. of rows updated ( after update takes place). How do i get to know the count of no. of rows to be updated/inserted/ deleted. I was looking for a simple solution, as above SQL%Rowcount. But i couldn't find any. I can use a Function and Return the value which will give me number of rows to be updated, But is there any Simple Logic other than this.. or any count function. Your Help is Appreciated. Thanks!

If you really want to do this (I have no clue why you would need it), then you can piggy back on any existing pessimistic locking you may already have in place.
However, it would require two loops through the records of which you want to know the count before you update, and a second pass to update them.
I would really re-think the need for this, though.

Hi Experts,
I am file as source and Oracle as target. My file containing the some data which is going to load to the target.
My requirement is that I want to count the number of rows which my file contains. Please help me how to count the total number of rows in file.
Thx,
Sahadeva.

Hi,
You won't give a name DEST_USER_NAME:ODI will get these information.
it is important Command on source and Command on Source side .
-Pls write jython code on Command on Source side
-And Command On Target side Choose technology as Oracle and set logical schema to HR_logical
Sorry my mistake.İt is related jython syntax.Here is code:
import java.lang as lang
import java.sql as sql
import java.lang.String
import os
lang.Class.forName("<%=snpRef.getInfo("DEST_JAVA_DRIVER")%>")
cons=sql.DriverManager.getConnection("<%=snpRef.getInfo("DEST_JAVA_URL")%>", "<%=snpRef.getInfo("DEST_USER_NAME")%>", "<%=snpRef.getInfo("DEST_PASS")%>")
dblinks= cons.createStatement()
file1=open('EMP.txt','r')
count=0
line=file1.readline()
while line !='':
count+=1
line=file1.readline()
file1.close()
sqlQuery = "insert into HR.ETL_FILE_LOG (FILE_COUNT) values (count)"

Can I "count" the number of rows excluding the header and footers

I have some tables that consist of a different number of rows, as the number is part of an equation I need to know the number of rows excluding the header and footers. I have the work around in =ROWS(ColumnG)-3, but is there a tidier way? I want to be able to add footers (or headers) too and not have these counted.
Many thanks
Lee

Hi Lee,
Add a column to your table (for purposes of this discussion, the new column is placed before column C, and becomes the new column C). enter the formula below in all regular cells, but NOT in header or footer cells:
=1
Use the formula below, placed anywhere (except in a regular cell in column C) to get the number of non-header, non-footer cells:
=COUNT($C)
The first formula will automatically be placed in cells added to column C, and the results will change to reflect the added rows.

Barry

Want to count the number of rows of analysis item in WAD Template

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 the number of rows

I have a JSP page that access to a JAVA class, where I connect with the MySQL data base, and where I make some consults.
Hi, I need to knows how many rows I get from a SELECT consult.
I have this class to do:
package connectDB;
import java.lang.*;
import java.sql.*;
public class MyConnection{
        Connection dbconn;
        ResultSet results;
        PreparedStatement sql;

                try
                Class.forName("org.gjt.mm.mysql.Driver");
                        try
                                dbconn = DriverManager.getConnection("jdbc:mysql://localhost/MyDataBase?user=USER&password=PASSWORD");

   try{
      String consulta = "SELECT count(id_file) as numero FROM File_user where id_file>0";
      sql = dbconn.prepareStatement(consulta);
      results = sql.executeQuery();
      numberRows = results.getInt("numero");

Count the number of rows in each table

I have a list of table names, how to I write a query to find out the row count of each table.
select table_name from all_tables a where owner='XXX' and num_row > 100
or
select table_name from all_tables a where owner='XXX' and sample_size > 100
doesn't quite work.
Why?
