Sorting based on count of rows

Hi all,
I have a problem at hand. A table BEERS looks as follows:
BEER_NAME      QUANTITY PRIORITY
Budweiser      17        1
Budweiser      16        2
Corona         22        1
Heineken       9         1
Heineken       11        3
Guinness       15        2
Corona         2         2
Heineken       13        2Here, I would like to arrange Beers in cases based on priority.
No beer of different brand should go in the same case.
No beer with same brand with different priority should go in the same case.
The maximum number of bottles that can be accomodated in a case is 10.
I wish to have a query which gives the result as follows:
BEER_NAME      QUANTITY PRIORITY
Budweiser      10        1
Budweiser      7         1
Budweiser      10        2
Budweiser      6         2
Corona         10        1
Corona         10        1
Corona         2         1
Heineken       9         1
Heineken       10        3
Heineken       1         3
Guinness       10        2
Guinness       5         2
Corona         2         2
Heineken       10        2
Heineken       3         2How would I get this?

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.

Sorting based on a specific value in Columns

Hi All,
Crystal 2008 version I have. And we are connecting to BW queries as source.
In a crosstab, I want to sort my row values based on a column value.
For example, in rows I have an element with three values . In column I have only one element(month), with couple of month values. My requirement is to sort rows based on a specific month (Mar'09 for example).
.....................Jan'09......Feb'09.....Mar'09
ABC...............10.............323...........33....
XYZ...............32..............33............11....
FGH...............5................34.............55...
But when I try to sort based on the Month, I can not select a specific value(mar'09). And it sorts based on the total value (sum of all months).
How can I achieve this problem?
Thanks
Ozan

For {Sort Value}, if you wanted to sort on the Jan column, then substitute the field name that your example shows as 10 in row ABC. For {row value}, substitute the field name that is used in the first column (ABC in the example).
In other words, take the value that you want to sort on, and put it in front of the value currently displaying as the row header. Then, sort on the results.
The purpose of the "000000000.00" is to make the length of the number, when converted to string, a consistent size. This is needed (a) so you know how many characters to strip off when displaying the row value, and (b) so the records don't sort as 1, 12, 2, 234, 235423, 25, 3, ...

Is it possible to sort by word count

I have a list of titles and wish to arrange them by the number of words in each title, any suggestions gratefully received

Hi FF,
Word processing applications usually define a 'word' as a group of characters followed by a space (or a return).
I haven't foud a way to directly count the number of spaces in a string of text, but Numbers does support FIND() which can determine the position of a specific character's first appearance in a string or after a specified position in a string.
That's the method used in the coloured cells of the table below.
C2: =IFERROR(FIND(" ",$B,1+MAX($B2:B2)),"")
Fill right for as many cells as there are words in the 'longest' title.
Fill down to the end of the table.
A count of the cells containing numbers in the row (not including the cell in A, which must be a Header column) will give the number of spaces in the title. Add 1 for the number of words in the title.
A2: =IF(LEN(B)>0,COUNTIF(2:2,">0")+1,"")
Fill down to the last row in the table.
Sort on column A to arrange the titles by length in words.
Note the results in rows 5 and 6.
Row 5 contains the title of Paul Zindel's 1964 play as he wrote it. Man-in-the-Moon is considered as a single word in the count.
Row 6 contains the same title with the hyphens replaced by spaces. Man in the Moon now counts as 4 words.
Rows 7 and 8:
George Orwell's title is read as a number. As it's greater than 0, the number is included in the count. 1 is added to account for there being no space after the 'last word' in the title to give a count of 2. (Result is the same when the title is entered as '1984 (the leading ' tells Numbers, and other spreadsheets, to format the cell as text), of when the cell's format is set to Text using the Inspector.)
In row 8, 1984 is enclosed in quotation marks, and is now treated as text (with a numerical value of zero).
As noted, the columns doing the calculations may be hidden.

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

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.

'Count all rows' in Disco Plus?

Hi all - I can't find an option to Count All Rows in disco plus. This is something my users use all the time in Desktop - is it included in Plus?
In Desktop, it is under menu item 'Sheet'
Thanks!
Scott

Hi Scott
Sorry that was removed from Discoverer Plus so you won't find a button for it. Having that there would force Discoverer to have to run the entire query just to give you the total count. Oracle considered this a waste of resource and query effort, which I sort of agree with because I can see what they are getting at, and so removed it.
Best wishes
Michael

URGENT - Does Select Query Sort based on RowId ?

Does Select Query Sort based on RowId ?
Eg: Select * from Employee;
RowId primkey name
aaaa 1 kiran
aaab 2 kumar
aaac 3 someone
Now when i delete the primkey: 2 row.
I will have:
RowId primkey name
aaaa 1 kiran
aaac 3 someone
Now when i insert a new record:
RowId primkey name
aaaa 1 kiran
aaac 3 someone
[Comment: Here the rowid can either be a new one like 'aaad' or 'aaab' is also reused.]
aaad 4 somename
My requirement is that the 'aaab' should not be reused.
Can any one pls suggest some way.

How to filter a report based on count?

Here is my scenario: We would like to report activities on a server if there are multiple date in a month. Here is an example:
Server Date Activity
Server1 7/1/09 Hardware maintenance
Server2 7/1/09 Hardware maintenance
Server2 7/14/09 Software patching
Server2 7/14/09 Server reboot
Server3 7/5/09 Hardware maintenance
Server3 7/5/09 Server reboot
The report will show the following
Server2 7/1/09 Hardware maintenance
Server2 7/14/09 Software patching
Server2 7/14/09 Server reboot
Server1 and Server3 will not show up since there is only one date in July (even though there are two activities for Server3).
I thought of using a report as a filter to a second report. In the first report, find a way to determine which server to report on. But how would I finter the 1st report based on count as the logic stated above?

Hi Max
Our requirement is to see all the activities for a server in a month ONLY IF there are activities on DIFFERENT dates. So using my example, server2 has activties on 7/1 and 7/14. Then we want to see all the activities for server2 in that month. Server3 has two activities but both activities are on the same date. So we don't want to see server3.
Counting by server will not work because that will include server3 in my example.
What I really want is to be able to count unique occurrences of dates per server in a month. And if this count is > 1, then this server will be in the report.
I used a pivot table to count the unique occurrences of dates by server by month. So using my example, I have this result:
Server1-July: 1
Server2-July: 2
Server3-July 1
What I really want (conceptually) is to be able to filter this pivot table by the matrix column which is the count. I just couldn't figure out how to do that :). Then I thought I could use this report (with pivot table result) as a filter into another report.
Hope you have some idea....:)
Thanks

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 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 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
