How can I get Dataset Row Count from Javascript function in BIRT. I tried searching this in BIRT exchange, but the only solution offered there is to have a new dataset getting count of values of required data set. This wont suit my needs.
Is there any way to obtain it using dataset events.
An easy way would be to count dataset items in a report variable.
Declare a new variable in your report outline:
Reset it in beforeOpen script of the dataset (in case this dataset is invoked multiple times during report execution):
vars["items"]=0;
Increment the variable in onFetch script of the dataset:
vars["items"]++;
Use your variable in any expression. For example add a dynamic text element in report's body such:
"Items count="+vars["items"]
Important 1: This approach works if and only if the dataset is bound to at least one report element (a table, chart, data element, etc.). For example, it won't work if the dataset is only invoked to fill a list of selection choices of a report parameter.
Important 2: In the body of the report, this variable can only be used after the first report element using the relevant dataset, otherwise it won't be initialized
Dominique has a great answer; It is not clear to me from your question if this simpler solution might also meet your needs.
In your data set use a computed column with a value of '1', then sum the values.
You can write JS that only adds the value if specific criteria are met.
Or you can use an aggregation on your report to sum the values, which would be after any filters or groups are placed.
There is a simpler way if you use the row number in your tables footer:
In the 'Dynamic Text' element you can select:
Avilable Column Bindings > Table > RowNum
Add 1 as the index starts with 0.
You could also make a variable and then add to that for each row created in a table.
For example, in the Table-Detail script, set an onCreate event to check for a value in each row and if there is one to increase the row count. The following onCreate script would check if the row is empty. If the row is not empty, the script increases the counter and goes to the next row.
var checker = this.getRowData().getExpressionCount();
if( checker > 0 ) vars["Counter"]++;
Then you could add dynamic text after the table with the following expression:
"Row count="+vars["Counter"]

I am trying to produce a user interactive table like Target table
The yellow columns represent editable columns, white ones can't be edited, and they work in following fashion
User updates column B and allocates 100% of distribution among the three rows(40,35,25 in this case). A total is shown in footer to help user identify correct allocation of 100%
Column A updates in backend by multiplying each % with a predetermined number(1000 in this case). A total is shown, which would be 1000 if user entered % correctly
User then enters values in column C. No total is necessary here
Column D is then calculated in backend as a product of column A and column C
Is this achievable by any simple means?
I also then want to reuse this table for more calculations since this is the input prompt
Thank you very much.
You can do most or all of this with the tools you tagged but it won't be simple:
The DT package will not do all of this for you: you will also have to use reactivity.
This link discusses working with edited values in DT, providing an idea of the level of difficulty to expect: R -shiny- DT: how to update col filters.
In addition to what you see in the example, you want to add formatting, a totals row, and only allow editing of some columns, which will require more work.
I am fairly new to using PeopleSoft BI Publisher plugin for MS Word and integrating it with PS Query Manager. My question is whether in the RTF file you can put logic to suppress or filter out data?
I have a for-each grouping that prints a line (row). I would like to add logic to NOT print the line if the Witholding amount field (M.WTHD_AMT) is equal to 0 (zero). My question is what would the syntax look like, and where should I place it (on the For Each grouping below, the Field level, or somewhere else?) I know I can alter the PS Query (data source) to do the filtering but I would like to leave that as-is and handle this in the template.
I see that there is another conditional IF statement ("rmt_") so I'm not sure if I can add this additional logic to that element or if I need a separate one. I appreciate any feedback!
EDIT:
I've added a new "Conditional Region" as suggested, and it works with just the WTHD_AMT criteria !0 to zero, however I tried added additional criteria where L.PYMNT_TYPE = 'R' and when I run the process it doesn't display data on the PDF output. Is there something wrong with the syntax? Do I need to have a separate Conditional Region for this 2nd criteria? I've seen another BI report where they have 2 or 3 criteria as part of one element.
<?if:number(M.WTHD_AMT)!=0.00?> and <?if:L.PYMNT_TYPE='R'?>
Option 1
You can nest <?if?> statements. Just add another <?end if?> at the end. Make sure there are no spaces between the all of the IF or END IF objects at the beginning or end of the content/row, else the row may still be displayed.
Option 2
You can add conditions in the repeating section. Below will repeat the region for every record where M.WTHD_AMT is not 0.00
<?for-each:record_path/record[M.WTHD_AMT!='0.00']?>
'Conditional Region' is the button you are looking for.
When using this button, make sure to double check where the if/endif or C/EC elements are added. It tends to ignore the selected element and join the elements to the start and end of the line. You will then need to cut and paste it into the right spot. For you this will probably be right after the F element and before the E element.
I’m looking for a simple expression that puts a ‘1’ in column E if ‘SomeContent’ is contained in column D. I’m doing this in Azure ML Workbench through their Add Column (script) function. Here’s some examples they give.
row.ColumnA + row.ColumnB is the same as row["ColumnA"] + row["ColumnB"]
1 if row.ColumnA < 4 else 2
datetime.datetime.now()
float(row.ColumnA) / float(row.ColumnB - 1)
'Bad' if pd.isnull(row.ColumnA) else 'Good'
Any ideas on a 1 line script I could use for this? Thanks
Without really knowing what you want to look for in column 'D', I still think you can find all the information you need in the examples they give.
The script is being wrapped by a function that collects the value you calculate/provide and puts it in the new column. This assignment happens for each row individually. The value could be a static value, an arbitrary calculation, or it could be dependent on the values in the other columns for the specific row.
In the "Hint" section, you can see two different ways of obtaining the values from the other rows:
The current row is referenced using 'row' and then a column qualifier, for example row.colname or row['colname'].
In your case, you obtain the value for column 'D' either by row.D or row['D']
After that, all you need to do is come up with the specific logic for ensuring if 'SomeContent' is contained in column 'D' for that specific row. In your case, the '1 line script' would look something like this:
1 if [logic ensuring 'SomeContent' is contained in row.D] else 0
If you need help with the logic, you need to provide more specific examples.

I am using PHPExcel_v1_8, I have implemented formula to some cells like following.
$objPHPExcel->getActiveSheet()->SetCellValue('G4','=SUBTOTAL(2,B6:B'.$row.')');
$objPHPExcel->getActiveSheet()->SetCellValue('H4','=ROUND(SUBTOTAL(9,Q6:Q'.$row.'),2)');
I also tried like
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow(6,4,'=SUBTOTAL(2,B6:B'.$row.')');
Here $row means total number of rows.
But when I filter any column then it append/override value of formula applied cell. Please see following filtered total row.
I want only latest value should in filtered total row means want to replace existing value. Right now, I am getting correct value but why it is overrided? Any suggestions what can be the solution?
You've actually discovered a genuine bug here.
I wasn't aware when I implemented the SUBTOTAL logic in PHPExcel that it only worked with visible rows, and ignored hidden rows. Can you please raise an issue on the github repo
However, reading through the MS Excel docs for SUBTOTAL, a function of 2 or 9 will return the result for all rows in the range (hidden or otherwise) while 102 or 109 will return the result only for visible rows
I have a QTableWidget that I populate like this:
// Clear the table
this->topPatchesTableWidget->setRowCount(0);
this->topPatchesTableWidget->setRowCount(numberToDisplay);
for(unsigned int pairId = 0; pairId < numberToDisplay; ++pairId)
{
// Display patch match scores
QTableWidgetItem* myLabel = new QTableWidgetItem;
myLabel->setData(Qt::DisplayRole, myValues[pairId]);
this->tableWidget->setItem(pairId, 0, myLabel);
... fill other columns ...
}
(I have some other UI elements to set properties that compute the values in myValues). If I change the properties, recompute, and recreate the table, everything works as expected. If I sort the table by clicking on one of the headers, it sorts correctly. HOWEVER, if at this point (after sorting) I click my button again to recompute the values and recreate the table, the table is very broken. That is, many of the cells are empty, and the cells that are not empty don't seem to be in any particular order.
By adding a manual call to
this->tableWidget->sortByColumn(0, Qt::AscendingOrder);
at the beginning of my CreateTable function, everything works as expected, but of course the newly created table is sorted by column 0 rather than the column that was selected for the last sort.
Does anyone have any idea why things would go so wrong without the call to sortByColumn? (I tried to make a simple example but I can't replicate the problem in a demo program).
Thanks,
David
I had a similar problem in python, if a column header was selected to enable sorting the cells after that column stopped populating.
I got around it by setting self.tableWidget.setSortingEnabled(False) at the beginning of the row add method, then setting it back to self.tableWidget.setSortingEnabled(True) at the end of the row add method. According to riverbank computing this is the officially recommended way to address this problem.
QTableWidget.setItem (self, int row, int column, QTableWidgetItem item)
Note that if sorting is enabled (see sortingEnabled) and column is the current sort column, the row will be moved to the sorted position determined by item.
If you want to set several items of a particular row (say, by calling setItem() in a loop), you may want to turn off sorting before doing so, and turn it back on afterwards; this will allow you to use the same row argument for all items in the same row (i.e. setItem() will not move the row).
See also item() and takeItem().
This is an elaboration on Karnisov's answer, also with PyQt. Disabling sorting before doing any setItem()s also worked for me, but it caused the user's sort selection to be lost, so I did it like this, where t is a QTableWidget:
oldSort = t.horizontalHeader().sortIndicatorSection()
oldOrder = t.horizontalHeader().sortIndicatorOrder()
t.setSortingEnabled(False)
# make the changes
t.sortItems(oldSort, oldOrder)
t.setSortingEnabled(True)
Note that it is still possible for the sort to change slightly with this code. This appears to be because the sort that Qt is using here doesn't move any items that were already in order, so if we had a table like this:
NUMBER LETTER OTHER LETTER
1 B C
2 G Q
3 A Q
If we sort by NUMBER, then by OTHER LETTER, nothing changes. But if we sort by LETTER, then by OTHER LETTER, we get:
NUMBER LETTER OTHER LETTER
1 B C
3 A Q
2 G Q
So if we had previously sorted by LETTER, then OTHER LETTER, this code would only do a single sort by OTHER LETTER, and we'd end up with the second version of the table instead of the first (assuming that the order the elements were added to the table in matches NUMBER). In this spot in my code, all items are deleted and re-added to refresh the table, so this can sometimes cause noticeable changes in order.
I had the same problem - always, when I wanted to insert new data, i buildet the header and setSortingEnabled(true). I guess the QTableWidget does not like several calls for setSortingEnabled(true). So I put it into the constructor of my MainWindown, and thats it!
I never figured out what was wrong with this. I gave up and implemented a custom model/view which is probably a much better idea anyway.
