I have a view with 2 columns. Both number types. I want to add a button to the page, which will calculate the ration between total of column 1 and total of column 2.
For example:
Column 1 | Column 2
5 | 5
10 | 10
4 | 3
3 | 4
It should be (5+10+4+3)/(5+10+3+4) = 1..
Thank you,
Florin
I would probably go into the view properties and turn on the totals for both those columns. Then in SSJS I'd get a NotesNavigator for that view and then create a NotesViewEntry object. Then I'd set that ViewEntry to the NotesNavigator.getLastEntry()... something like that. That entry should then have a columnValues() property. I THINK it would be something like:
var column1 = entry.getColumnValues()[1];
var column2 = entry.getColumnValues()[2];
Note: getColumnValues() is zero based and depending on the view design some columns might not be available to retrieve from getColumnValues().
Once you have you're 2 var's then you can do the math and do whatever with the result.
That's how I would approach it at least.
(I don't have an editor handy so sorry if some of the syntax is off)

I've been trying to find an answer for this, but haven't succeeded - I need to sum a column for a specified date range, as long as my rowname matches the reference sheet's column name.
i.e
Reference_Sheet

Have to work in google sheets, and I tried using SUMPRODUCT which told me I can't multiply texts and I tried SUMIFS which let me know I can't have different array arguments - failed efforts were similar to below,
=SUMIFS('Reference_Sheet'!B2:AO1000,'Reference_Sheet'!A1:AO1,"=A4",'Reference_Sheet'!A2:A1000,">=B1",'Reference_Sheet'!A2:A1000,"<=B2")
=SUMPRODUCT(('Reference_Sheet'!$A$2:$AO$1000)*('Reference_Sheet'!$A$2:$A$1000>=B$1)*('Reference_Sheet'!$A$2:$A$1000<=B$2)*('Reference_Sheet'!$A$1:$AO$1=$A4))
This might work:
=sumifs(indirect("Reference_Sheet!"&address(2,match(A4,Reference_Sheet!A$1:AO$1,0))&":"&address(100,match(A4,Reference_Sheet!A$1:AO$1,0))),Reference_Sheet!A$2:A$100,">="&B$1,Reference_Sheet!A$2:A$100,"<="&B$2)
But you'll need to specify how many rows down you need it to go. In my formula, it looks down till 100 rows.
To change the number of rows, you need to change the number in three places:
&address(100
Reference_Sheet!A$2:A$100," ... in two places
To briefly explain what is going on:
look for the person's name in row 1 using match
Use address and indirect to build the address of cells to add
and then sumIfs() based on dates.
alternative:
=SUMPRODUCT(QUERY(TRANSPOSE(QUERY($A:$D,
"where A >= date '"&TEXT(F$1, "yyyy-mm-dd")&"'
and A <= date '"&TEXT(F$2, "yyyy-mm-dd")&"'", 1)),
"where Col1 = '"&$E4&"'", 0))
I'm building a table to manage some articles:
Table
| Company | Store | Sku | ..OtherColumns.. |
| 1 | 1 | 123 | .. |
| 1 | 2 | 345 | .. |
| 3 | 1 | 123 | .. |
Scenario
Most time company, store and sku will be used to SELECT rows:
SELECT * FROM stock s WHERE s.company = 1 AND s.store = 1 AND s.sku = 123;
..but sometimes the company will not be available when accessing the table.
SELECT * FROM stock s WHERE s.store = 1 AND s.sku = 123;
..Sometimes all articles will be selected for a store.
SELECT * FROM stock s WHERE s.company = 1 AND s.store = 1;
The Question
How to properly index the table?
I could add three indexes - one for each select, but i think oracle should be smart eneugh to re-use other indexes.
Would an Index "Store, Sku, Company" be used if the WHERE-condition has no company?
Would an Index "Company, Store, Sku" be used if the WHERE-condition has no company?
You can think of the index key as conceptually being the 'concatenation' of the all of the columns, and generally you need to have a leading element of that key in order to get benefit from the index. So for an index on (company,store,sku) then
WHERE s.company = 1 AND s.store = 1 AND s.sku = 123;
can potentially benefit from the index
WHERE s.store = 1 AND s.sku = 123;
is unlikely to benefit (but see footnote below)
WHERE s.company = 1 AND s.store = 1;
can potentially benefit from the index.
In all cases, I say "potentially" etc, because it is a costing decision by the optimizer. For example, if I only have (say) 2 companies and 2 stores then a query on company and store, whilst it could use the index is perhaps better suited to not to do so, because the volume of information to be queried is still a large percentage of the size of the table.
In your example, it might be the case that an index on (store,sku,company) would be "good enough" to satisfy all three, but that depends on the distribution of data. But you're thinking the right way, ie, get as much value from as few indexes as possible.
Footnote: There is a thing called a "skip scan" where we can get value from an index even if you do not specify the leading column(s), but you will typically only see that if the number of distinct values in those leading columns is low.
first - do you need index at all? Indexes are not for free. If your table is small enoguh, perhaps you don't need index at all.
Second - what is data structure? You have store column in every scenario - I can imagine situation in which filtering data on store dissects source data to enough degree to be good enough for you.
However if you want to have maximum reasonable performance benefit you need two:
(store, sku, company)
(store, company)
or
(store, company, sku)
(store, sku)
Would an Index "Store, Sku, Company" be used if the WHERE-condition has no company?
Yes
Would an Index "Company, Store, Sku" be used if the WHERE-condition has no company?
Probably not, but I can imagine scenarios in which it might happen (not for the index seek operation which is really primary purpose of indices)
You dissect data in order of columns. So you group data by first element and order them by first columns sorting order, then within these group you group the same way by second element etc.
So when you don't use first element of index in filtering, the DB would have to access all "subgroups" anyway.
I recommend reading about indexes in general. Start with https://en.wikipedia.org/wiki/B-tree and try to draw how it behaves on paper or write simple program to manage simplified version. Then read on indexes in database - any db would be good enough.
I've searched quite a bit for this and can't find a good solution anywhere to what seems to me like a normal problem for this product.
I've got a data table (in memory) that is from a rollup table(call it 'Ranges'). Basically like so:
id | name | f1 | f2 | totals
0 | Channel1 | 450 | 680 | 51
1 | Channel2 | 890 | 990 | 220
...and so on
Which creates a bar chart with Name on the X and Totals on the Y.
I have another table that is an external link to a large (500M+ rows) table. That table (call it 'Actuals') has a column ('Fc') that can fit inside the F1 and F2 values of Ranges.
I need a way for Spotfire Analyst (v7.x) to use the selection of the the bar chart for Ranges to trigger this select statement:
SELECT * FROM Actuals WHERE Actuals.Fc between [Ranges].[F1] AND [Ranges].[F2]
But there aren't any relationships (Foreign keys) between the two data sources, one is in memory (Ranges) and the other is dynamic loaded.
TLDR: How do I use the selected rows from one visualization as a filter expression for another visualization's data?
My choice for the workaround:
Add a button which says 'Load Selected Data'
This will run the following code, which will store the values of F1 and F2 in a Document Property, which you can then use to filter your Dynamically Loaded table and trigger a refresh (either with the refresh code or by setting it to load automatically).
rowIndexSet=Document.ActiveMarkingSelectionReference.GetSelection(Document.Data.Tables["IL_Ranges"]).AsIndexSet()
if rowIndexSet.IsEmpty != True:
Document.Properties["udF1"] = Document.Data.Tables["IL_Ranges"].Columns["F1"].RowValues.GetFormattedValue(rowIndexSet.First)
Document.Properties["udF2"] = Document.Data.Tables["IL_Ranges"].Columns["F2"].RowValues.GetFormattedValue(rowIndexSet.First)
if Document.Data.Tables.Contains("IL_Actuals")==True:
myTable=Document.Data.Tables["IL_Actuals"]
if myTable.IsRefreshable and myTable.NeedsRefresh:
myTable.Refresh()
This is currently operating on the assumption that you will not allow your user to view multiple ranges at a time, and simply shows the first one selected.
If you DO want to allow them to view multiple ranges, you can run a cursor through your IL_Ranges table to either get the Min and Max for each value, and limit the Actuals between the min and max, or you can create a string that will essentially say 'Fc between 450 and 680 or Fc between 890 and 990', pass that through to a stored procedure as a string, which will execute the quasi-dynamic statement, and grab the resulting dataset.
Here is the scenario, I have a dataset with fields Category, Country and NUM_SCHOOLS.
i created a column to populate the country names as columns. I created a row group to calculate the row column. In my current report Column headers(Country) Country1, Country2....so on are displayed and row headers(Category) A, B, C and D are displayed. Values is [Sum(Fields!NUM_SCHOOLS.Value)]. Everything is correctly displayed
I used pipe(|) symbol as the separator between the cells, i am not allowed to post images, i tried my best to explain. Please let me know if you need any information to help me.
Current Report:
Country1 Country2
A 10 | 12
B 5 | 6
C 5 | 7
D 11 | 15
Required report:
Country1 Country2
A 10 | 12
B 5 | 6
C 5 | 7
D 26
Only for D column, i want to add the numbers and display the value as a single value. (11+15=26), for other categories it should display in different country buckets.
Please help me out. Thanks in Advance!

Sorry to be the bearer of bad news, but I don't think that you can merge columns across column groups.
I think that the best option is to remove your column grouping and manually add in 7 columns for your receipt frequencies. You'd have to use a Sum with an Iif to get your values correctly, for instance in the far left column, something like:
=Sum(iif(fields!RECIEPT_FREQUENCY.Value="ANNUAL" ,Fields!val.Value,0))
then you could add a merged cell underneath and add the following expression
=Sum(iif(Fields!PART_COUNT.Value="D", Fields!val.Value,0),"DataSetName")
Alternatively, you could leave it as it is and enter the following expression in a total row at the bottom of your matrix. But you would have to do something expression based for the cell borders to give the illusion of it being merged..
=Sum(iif(Fields!PART_COUNT.Value="D"
And fields!RECIEPT_FREQUENCY.Value="BI-WEEKLY"
,Fields!val.Value,0),"DataSetName")
I have been trying to come up with a birt report to print food tag to no avail. What i want to show on the report is:
foodtag1 | foodtag2 | foodtag3
foodtag4 | foodtag5 | foodtag6
foodtag7 | foodtag8 | foodtag9
Can this be done?
the data is taken from a MySql Query "select dishes.name
from dishes
where find_in_set (dishes.id,(select orders.dishes from orders where orders.id = ))"
** Note: FoodTags 1-9 are all unique name of dishes
** Also note that foodtag 1-9 are representatives of a dish name. FoodTag1 can be "Yang Zhou Fried Rice", it can be "italian Pasta". it can be "Mee Goreng". Data is taken out from a datasource in MYSQL server
The easiest way--
Drag a grid element to your report, set it at 3 columns and 3 rows
In property editor, bind the grid to the data set
Drag a dynamic text element to the first cell in the grid
Then use JavaScript simular to this to filter to the desired text.
if (row["FoodTagColumn"]=='foodtag1'){
row["FoodTagColumn"]
}else null
