Please advise (syntax) on how to reference a text object in QlikView to pick its value.
My object is called: TX1, it is a text box and it is defined like this:
=SUM( TOTAL Income)
Why do I need this?
I have a chart with Persons as a dimension, and the expression should calculate each person's income/total income.
The total income needs to be taken from that textbox with alternate state so it remains unaffected by the filter selections (or the dimension that forces total income to be seen as total income belonging to each person).
Thank you.
Any selections you make in your dashboard will have an effect on relational data shown within a text-box.
You can, however, store the initial value of your expression and keep it for later use.
Create a variable called vInitialSum or something, and set it upon opening the document. You'll then have the untouched (unfiltered) value of =SUM("Total Income") to use at your disposal.
Add the trigger in Settings > Document Properties > Triggers > OnOpen:
Just use this:
SUM({1}Income)
The "{1}" tells the formula to ignore any selections and calculate on the full data set. For more details, see "set analysis" and "set modifiers" in the help.

first, i wanna show only pie graph.
and only if i select one of the pie graph fragments, I'd like to show the corresponding bar graph value.
Is there a way?
In QlikView
Open the chart preferences
Add the calculation condition = GetSelectedCount(FieldName) = 1 (More about GetSelectedCount function)
Open Error Messages
Select Calculation condition unfulfilled
Enter the message. It can be a plain text or expression/calculation
Now if nothing is selected in Director field (or more than one value is selected) the error message will be shown
If only one value is selected then the chart will be calculated
In Qlik Sense
In the chart properties expand Data handling and add the condition in Calculation condition and the message in Displayed message (as in QV the message can be plain text or calculation)
Nothing is selected (or more than one is selected) and the message is shown
Only one value is selected and the chart is calculated
I am having issues with setting a Validation rule in Access.
I have a database with the tables Clients, TypeClient, Sales, SalesList, Items.
I have a form for Sales, with a sub-form SalesList inside which has a relationship with Items in order for me to put several stock items in Sales instead of only one item.
Inside Sales table is ID, Date Sold, ID Client.
Inside SalesList is ID_List(referenced to ID in Sales), ID_Item(referenced to ID in Items), Quantity.
Inside Items is ID, Name, Stock(how much we have in stock), Price
The issue is that I am trying to validate the data I enter in the sub-form Quantity field to be higher than 0, but no higher than the available stock.
The issue is that I have tried using the expression builder to get the value from a calculated query that has 2 fields - the ID and the value for that id, with criteria that is for the ID to get it from the main form, the sub-form, the combo box input and the query works.
But when trying to get it like this:
It shows an error "The expression [Query bla] you entered in the form control's ValidationRule property contains the error The object doesn't contain the Automation object 'Query bla'".
I tried using directly the table Value(but it won't work anyway as it doesn't know for which field to get the stock value from), still the same error. I guess it can't reference to anything else? Normal validation rules work, but I want to validate it not to exceed the value of the available stock for the item I am selling now.
Nowhere on the internet there is a tutorial how to do it with expression builder. How do people validate their fields then?
It doesn't stop me in this case to sell 200 items when I currently have stock of only 2 of them, for example.
Note: I have tried DlookUp in expression builder, straight up tells me No.
Sample wrong validation rule expression builder code:
<=[Query bla]![Stock]
<=[Items]![Stock]
I am currently using VBA and fetch the record I need(the current stock) with one of the following and my unbound text is changing on every subform to the same, it shouldn't happen like that. What can I use to populate a field for each record uniquely:
Private Sub ID_Product_IZBOR_Click()
'Me.Stock_ValueField = DLookup("[Nalichnost]", "Stoka", "[ID]=" & Me.ID_Product_IZBOR)
Me.Stock_ValueField = Me.ID_Product_IZBOR.Column(2)
End Sub
Partial solution: I created a new Dim as Integer and fetched the records based on the ID provided by the field in the form and used BeforeUpdate to validate the current stock. Unfortunately the only way to see the current stock level is to click on the combo box where you choose your product and check the column for that one, it doesn't show anywhere else :(
Don't use the expression builder (I NEVER do) - just type the needed expression in property.
>0 AND <=DLookup("Stock", "Items", "ID=" & [ID_Item])
Another approach is to return Stock in textbox ControlSource then ValidationRule references that textbox. Also, user can then see the quantity limit. Methods of pulling the Stock value from Items table:
include Stock field in Items combobox RowSource - textbox then references column by its index (index begins with 0): =[cbxItems].Column(2); VBA may be needed to Requery combobox after record entry/edit is committed to table.
include Items table in form RecordSource - bind textbox to Stock field (Locked yes and TabStop no)
DLookup() expression in textbox ControlSource
Use ValidationText property to give users a custom message.
However, ValidationRule will not prevent user not entering any value if they skip the control. If you want to make sure a value is entered, either set field as required in table or use form BeforeUpdate event to validate record data.
I'm new to SSRS 2012 and have a question about variables. I have a report that retrieves order and order line information from our database (order #, order line #, item, quantity, etc). I need to add a textbox to the footer of the report that can only be displayed for certain items (i.e. if item # equals "123" then show textbox, otherwise hide it.
I added a report variable called 'ItemExists', and unchecked the read-only flag, and set the default value to 0.
I then added an expression to the textbox on the report footer to show it if variable=1, and to hide it if variable=0.
I'm trying to add a textbox with an expression to the body of the report (same group as where the item # is displayed), but I'm unable to get the report variable to update properly. Here's what I tried:
=IIF((Variables!ItemExists.Value = 0) and (Fields!item.Value = "123"), (Variables!ItemExists.SetValue(1)), Nothing)
This works if the value of the item is 123, but if the item is not equal to that value, it still sets the ItemExists variable to 1.
The reason I'm checking to see if the variable is equal to 0 is that there may be multiple lines in the report, and if any one of the items is a match, I want the variable to be set to 1.
I'm not sure if I'm way off track here, but if you could provide any assistance on the best way to achieve this, that would be great.
Thanks in Advance.
My query returns location_cd(string) and item_count(int). I only need certain rows from the result however and I need them to display in specific places in my layout so I don't think the table solution is going to work. Can I determine where I place the value for a particular row of the result set?
I am using a grid to display values for a number of fields. I cannot seem to be able to get the values from the results to show. The grid is bound to the result set. I even tried binding the cells to the result set but that didn't work either.
I checked in the query editor and there is a result set shown in the Preview so I know the query works. The complete and correct result set shows if I put a table on the page.
I tried inserting a Dynamic Text or Data object in a cell and used the expression:
dataSetRow["location_cd"]=="3SD"?dataSetRow["item_count"]:""
This returns a blank and does not seem to evaluate. I tested it with :
dataSetRow["location_cd"]=="3SD"?dataSetRow["item_count"]:"BLANK"
and got 'BLANK' to appear in that cell.
dataSetRow["location_cd"] and dataSetRow["item_count"] will display the location_cd and item_count from the first row of the result set. row.outer[] did the same thing. Obviously I am just hacking at this report at this point.
A co-worker suggested that she uses a JAVA if-statement in places like this but I could not get that to work either.
Any ideas or suggestions that will get me on the right road??
Thanks
An elegant option would be to use a HashMap storing the result of the dataset.
Declare a report variable named "values", with a new hashmap as default value (see image below)
Fill values in the onFetch script of the dataset: vars["values"].put(row["location_cd"],row["item_count"]);
Insert new data elements at any place of the report with expressions such: vars["values"].get("myFavoriteLocationCD");
Though it is important to note the dataset should be triggered by the report before these data elements.
The particular row you want to display you specify in a "Text" field inside your grid. Just drag and drop a "Text" field inside your grid. If you bound the fields you want to display to your grid, the "Text" field inside the grid inherits the bindings of its parent (the grid), so you can access the bindings automatically in the "Text" field.
You could try following steps, maybe that works.
Don't use "Dynamic Text" field, instead use a regular "Text" field
Ensure the fields of your query which you use, are bound to the grid (you sayed you already did)
Open the "Text" field
Change preselected pull-down entry "Auto" into "HTML"
Change preselected pull-down entry "Formatting" into "Dynamic Text"
Wrap your code in <value-of format="HTML"> your code goes here... </value-of>
Note: You should check in the "Expression Builder" of your "Text" field if you are able to access the fields you bound to the grid. If they are not available sth. went wrong with your binding. Avoid binding query records to cells this will drive you crazy.
If you want to display a list, ensure you didn't set a constant height in the row of your grid. Set the height to 100% than the row takes its height dynamically.
What about the idea to optimize your query, that only get the results you want are displayed, than you don’t need to filter them with java script? If you don’t need the filtered results in another place this would be the cleaner solution in my opinion.
I'm trying to show / hide fields in a Pentaho report based upon user input.
For example, I would like to offer a checkbox to the user saying "Show Product Count" -- if the box is unchecked, it will not include that column in the report.
Is there a way to do this in Pentaho Report Designer, perhaps using Parameters?
Thanks for the help -Monica
Yes, you have half the answer. Have a Yes/No Parameter "ShowProductCount"
Then on the conditional fields, go to the visible property, click the + formula icon and enter:
=IF([ShowProductCount]="Yes"; TRUE(); FALSE())
Simple! :)
There is more to this that the above answer. For example, if you don't want a field to show on the report, you pass the value mentioned above by Codek but the field will not show but the space for it will. The field has to be in a BAND and the band layout has to be set to ROW. Also, on the field you want to not display or display based on user selection, you have to set that field's style properties under size & position - invisible-consumes-space = false.
