Counting rows

Post Author: mavrick5
CA Forum: Formula
I have a problem I am hoping someone can solve. I have written a report that allows me to sum the sales, volumes, etc for transactions from any 2 reporting periods (this year/last year, this month/this month last year, etc.). In the report I have columns for items per transaction for either period. The calculation for the items per transaction is count of report lines / distinctcount of report lines. My problem is that if I am looking at the last period items per transaction value, it cannot distinguish between the records for the current period and last period. Additionally, if I am comparing the items per transaction for this period versus last period, both values are incorrect. I have a formula to determine if the row is in the current year. If I do a distinct count on this, I get the correct answer plus 1.eg. my formula is if {saleh.datewhen} >= {?FromDateLY} and {saleh.datewhen} <= {?ToDateLY} then {saled.sequence} The problem is that if the date of the transaction falls outside the date range, then it is assumed to be zero. Therefore, I get a count of the valid rows plus the zero when I do a distinct count. However, if I do a count, I get all of the invalid dates counted. as it counts every zero. How can I get around this issue? I cannot rewrite the report as it is far too complex. (The report has 4 columns of values that are completely variable depending upon the selection criteria for each column - about 20 options per column). If anyone has any ideas, I would be glad to hear them. I have had a similar problem in the past using count where I didn't want to count certain rows but it counts all values.

No. This data will only appear in GF1. The report is a drill down and these calculations will only appear at the top level. The top level is by store, then department, sub-department, etc. The items per transaction is only valid at the store level, as a transaction could contain items from multiple departments.I have set up a couple of test fields.{@Sequence} if {saleh.datewhen} >= {?FromDate} and {saleh.datewhen} <= {?ToDate} then {saled.sequence}else 0{@SequenceLY} if {saleh.datewhen} >= {?FromDateLY} and {saleh.datewhen} <= {?ToDateLY} then {saled.sequence}else 0 Now, lets say I have 5 rows of data in the first date range and 5 rows in the second. Doing a distinct count on either field will give an answer of 6, the 5 rows plus the 5 zeros which count as 1. However, if I do a count, I get 10 for both date ranges, because the zeros are counted for each row.I will try to use a variable to do a count if either field is not zero and see if that works.

Count rows from multiple tables using SQL only

Hi, I know this has probably been answered before, but I couldn't find the answer anywhere. Please help.
I'd like count(*) [rows] for all tables in database using SQL only - no PL/SQL
The result should be something like:
Table RowCount
DBA_TABLES 1000
DBA_USERS 50
etc.

SQL Developer 2.1 EA - count rows with filter on a table

This is a small problem that I came across today while using 2.1 EA. I opened a table and did a filter to narrow down the results of the table. Then when I right clicked on the search results and clicked on 'Count Rows'....I get the count of the rows in the table and not my search results.
Is this a feature or a bug?
Thanks,
Mike

In EA2, we get both the total and the filtered total, nice.
Only remark is we don't get a progress indicator anymore, and thus can't cancel a query that might take up hours to finish!
Please log a bug for this.
Thanks,

How to set Tile count column or count row?

How to set Tile count column or count row? If not can do, How
to adjust count row or count column?
Thx for all idea.

The Tile container's number of columns and rows is calculated
based on each child's width and height (or based on tileWidth and
tileHeight which you can set). If you need more control over the
layout, use Grid.

Can i count row from ResultSet ?

I would like to count row from ResultSet for
take it into my array object because i must know number of row before create array object.
Example:
ResultSet rset = stmt.executeQuery("select * from user ");
/*i = amount of ResultSet*/
User[] user = new User;
int l=0;
while (rset.next()){
user[l] = new User();
user.name = rset.getString(1);
l++;

Hi,
As per my knowledge there is no method by which you can get the count of items in a resultset directly. You will have to loop through the reseltset and set a variable for count. In your specific case I would advise you to use a Vetor instead of an array so that you need not bother about the size.
ResultSet rset = stmt.executeQuery("select * from user ");
Vector user = new Vector();
while (rset.next()){
user.addElement(rset.getString(1));
Now you will have a Vector that holds the user info. To retrieve the user info loop through the Vector.
for (int i; i<user.size(); i++){
userName = user.elementAt(i);
Hope I was of some help.
cheers!!!

Count rows that are max timestamp

Hi,
I'm trying to run a query that will count only rows that are max timestamp.
i have a submit table which has dates of submissions, however some application numbers have multiple rows in this table. I need to count only one row per application and it has to be the latest submission data.

Usually your problem can be described with 'Who cares'. I mean, for what reason do you do this? I doubt that there's a business need to get 100 % accurate answers for this. Normally such things are used to get a picture about the growth of data.
Personally I would prefer to have up-to-date statistics for all tables and just query the number of rows from there. Sufficient for me in < 99 % of all cases.

Excel ActiveX: Count Rows

Hi, I am trying to simply count the used rows in an excel spreadsheet (which I have done in the past).
Attached is a simple vi which I am trying to get to work. On my development PC, this works fine, counts the rows etc...on this PC I have Excel 2003.
When I create an EXE out of this VI and put it on another PC with Excel 2000, it returns "0" for the number of used rows.
Can ANYONE help me here, this is driving me insane.
Working in 7.1 (can use 7.0 or 8.0 if it makes it easier)
Thanks,

It is limiting but I place the biggest blame on Microsoft for changing the properties and methods so much between different releases. You could put all of your Excel functions in a library that you call dynamically. That way, you don't have to re-build the exe but just distribute the library specific to whatever version of Excel you need to support. Unless you really need some specific Excel formatting, you could also save to comma/tab delimited text files. All versions of Excel can open them and you won't have to make a career out of modifying your application for as long as Excel is going to be around.

Counting rows respect to the last status assumed

Hi,
I'm analyzing dossier data in a PowerPivot table.
In particular, I've three tables: the Dossier table, the Calendar table (date, week, month, quarter, semester and year) and the Status table for dossier.
In a same day, a dossier can change his status more times (from created to active, from active to closed, and so on): so in the Dossier table I've more dossier occurences with a status date and a sequence column to replace the time. For a new date, the sequence
column restarts to 1.
I need to count the dossier respect to the selected period (a specific date, a specific month, a specific year, and so on) by considering only the dossier with the last status date minor or equal than the selected period.
Fe, for these dossier data:
Dossier id      Status      Status_Date     Sequence
      1            Created    11/02/2015           1
      1            Active       11/02/2015          2
      1            Closed      11/02/2015          3
I must consider the closed dossier row with sequence = 3 when I select '11/02/2015' date from my calendar. The resulting dossier count has to be equal to 1.
I've created this DAX measure:
LAST_DOSSIER_STATUS_NUMBER:=COUNTROWS(
FILTER( VALUES(Dossier[DOSSIER_ID]);
CALCULATE(MAX(DOSSIER[SEQUENCE])) = CALCULATE( MAX(DOSSIER[SEQUENCE]) ; all(dossier[status_id]) ) ) )
It functions only if I select a date, but not if I select the month (february) or the year (2015).
I've tried to use FILTER and LASTDATE functions inside the CALCULATE( MAX(DOSSIER[SEQUENCE]) ; all(dossier[status_id]) ) expression but with no results.
Any helps for me, please? Thanks

Hi Imke,
for a specific day I could have three status change for a specific dossier, and so I could have three same occurence for a dossier: DISTINCTCOUNT(Dossier[DOSSIER_ID]) should return 1, but respect which status? If I should put the STATUS_ID on the rows of
a pivot table I could see 1 for the created status, 1 for the active status and 1 for the closed status. The goal is to show only 1 value for the closed status, that is the last status assumed for the specific dossier.
For the data posted next:
when I select 11/02/2015 as date I've the desired behaviour
but when I select 2015 as year I don't have the wanted behaviour (see dossier_id 1 and dossier_id 4):
The desired behaviour is to see for dossier_id 1 only status_id 4 and not status_id 2, for dossier_id 4 only status_id 4.
As row labels I've dossier_id and status_id, as filter I've a Time Hierarchy (date, month, year) built on a calendar table.
Thanks

Analytic function to count rows based on Special criteria

Hi
I have the following query with analytic function but wrong results on the last column COUNT.
Please help me to achive the required result.Need to change the way how I select the last column.
1)I am getting the output order by b.sequence_no column . This is a must.
2)COUNT Column :
I don't want the total count based on thor column hence there is no point in grouping by that column.
The actual requirement to achieve COUNT is:
2a -If in the next row, if either the THOR and LOC combination changes to a new value, then COUNT=1
(In other words, if it is different from the following row)
2b-If the values of THOR and LOC repeats in the following row, then the count should be the total of all those same value rows until the rows become different.
(In this case 2b-WHERE THE ROWS ARE SAME- also I only want to show these same rows only once. This is shown in the "MY REQUIRED OUTPUT) .
My present query:

So the issues are
1) the count column values are wrong in my query.
2)I dont want to repeat the same rows(Please see EXPECTED output and compare it against the original)
3)Want the output in exactly same way as in EXPECTED OUTPUT as I dont want to group by thor name(Eg. I dont want the count for all DUBLIN ROAD but I want to examine rows for the next one, if THOR/LOC combination is different in next row then COUNT=1 else COUNT=Count of no. of rows for that thor/loc combination until the combination change -So there are same value multiple rows which i need to show it in 1 row with the total count)
I am explaining below this in more detail!!
I only need 1 row per same THOR/LOC names coming multiple times but I need the count shown against that 1 row(i.e COUNT= how many rows with same thor/loc combination until THOR/LOC combo changes value).
Then repeat the process until all rows are finished..
If there is no multiple row with same THOR/LOC coming in the following row-i.e the following row is a different THOR/LOC combination, then the count for that row is 1.
Hope this is clear.
Is this doable?
Thanks in advance.

Count rows returned in a subquery in pl/sql block

Hi,
I'm working on a trigger in Oracle 11 to check that a student has met prerequisites before enrolling in a class. I need to determine how many rows came back on the query in order to determine if I should raise an exception or not. The following is raising the exception if the prereqs are complete or not. I've haven't included the code in the where clause because I've tested is seperately and get good results. I know this is limiited info, but is there some obvious mistake I've made here?
CREATE OR REPLACE TRIGGER prereq
BEFORE INSERT ON enrollment
FOR EACH ROW
DECLARE
howmany number;
BEGIN
select count(*)
into howmany
from dual
where exists ((insert code here that returns 0 rows if prerequisites are not met);
if howmany = 0 then
    raise_application_error(-20000, 'The prerequisites for this course are not complete');
end if;
end;
/

As you are selecting from dual you might hit no_data_found if the exist caluse doesnot return any row.
Try this,
CREATE OR REPLACE TRIGGER prereq
   BEFORE INSERT
   ON enrollment
   FOR EACH ROW
DECLARE
   howmany        NUMBER;
BEGIN
   SELECT COUNT (*) INTO howmany FROM DUAL;
               WHERE EXISTS ((INSERT code here that returns 0 ROWS IF prerequisites are NOT met);
EXCEPTION
   WHEN NO_DATA_FOUND
   THEN
      raise_application_error (-20000
                              ,'The prerequisites for this course are not complete');
END;You dont need count(*) from dual you can simply use
SELECT 1 INTO howmany FROM DUAL;
               WHERE EXISTS ...G.

Counting Rows in a message in BPM

Hi Experts, i need some knowledge sharing here.
Anybody can tell me how can we get the numbers of rows in a message by using loop in BPM?
I was thinking of using Loop and container node. But i still don't get it how can i use the loop condition so that my loop is not looping forever.
Thank you so much guys....

"I use the "Count" function in graphical message mapping and count the segments and add these to an unused field in the footer"
Hi thx for the reply, however, can you explain to me in more detail.
My scenario is i got a message with structure like this:
Source Message:
Header 1..1
    item 1..N
      Type 1..1
Target Message:L
Header 1..1
   result 1..1
Now, i want to count how many are there Type with value is for example 'E' and map it to the target message in node 'result'. So if there are 2 'Type' with value 'E' therefore the 'result' will filled with number '2'. If there is only 1 'Type' with value 'E' thus the 'result' will be filled with number '1'.
Do I have to use oneAsMany function?

Counting Rows from a ResultSet

Hi!
If I retreive some information from a database, say by using:
ResultSet RS = Stmt.executeQuery("select * from events");How can I get a value for the amount of rows in this ResultSet?
Thanks!
Alastair

Almost everyone, when they first use ResultSet thinks of it as a container with the data rows already in there, and wonders why there's no size method.
But that's not how they work. A ResultSet, generally, holds only one row at a time. next requests the next row from the database and before next is called the ResultSet doesn't know if another row is going to be available. Indeed the number of rows that qualify for return in the result set may actually change while you are processing it.
Doing the SELECT COUNT(*) request asks the database for the number of rows that match any criteria in the SELECT, but that number may have changed when you actually retrieve the rows. Someone else may have added or removed rows.

Counting rows in mysql

what command to i use to count the number of rows in a table and to do this will i use the statement
while (resultset.next()) {

You use the SQL statement "SELECT count(*) from WhateverTable", get a ResultSet from it, and then use this code to get the number:rs.next();
int rows = rs.getInt(1);
