I have two data tables A & B in a visualization. They can be joined by a common column ID.
Is it possible that the data chart from table B be limited by selection from table A?
Best Regards,
Jonathan
you can create a relationship based on that ID:
click Edit...Data Table Properties
click the Relations tab
click New to create a new relation
configure the relation by selecting the left and right tables, the column containing the ID on both table, and optionally a method to apply to values in that column
click OK a few times to accept all changes
...and then configure the Filtering panel to show this relationship:
open the Filtering Panel by clicking the button on the toolbar or View...Filters
find the header for your Table B and click the "Filtering" icon next to the expansion arrow (▼)
select Filtering in Table A ► and tick Include
now when you change filters on Table A, data will be limited in Table B to reflect it. only the currently-selected Filtering Scheme will behave like this; any other schemes will also need to be configured (steps 6-8).

I am trying to create a list of display fields and checkbox fields from a table column in Oracle Apex. For example, let's say I have a Table A. These are the values stored in A.
ID Health Conditions
-- -----------------
1 Heart Disease
2 High Blood Pressure
3 Diabetes
So now I want to display these 3 display fields associated with 3 checkboxes so the users can choose whether they have the above health conditions problems. If Table A has n values, then I can dynamically display n fields with n checkboxes. How can I do this?
The way I understood the problem, you should pre-populate table (which will contain info about those health conditions) and display the whole list as Interactive Grid (or Tabular Form, depending on Apex version you use).
It means that you'd store non-checked values as well (though, you could delete such rows on submit).
Alternatively, if you create an "empty" Interactive Grid page and let users add rows, and for each row select health condition they have, you'd store only selected values.
Yet another option is to create a page with shuttle item (or select list that allows multiple selections) so that user would select only desired values and store them. Drowback of such an approach is that all values are stored into the same column (read: it is not normalized) separated by colons. That's OK for selecting values, but causes problems later when you have to do something with it as you have to first split values into rows and then do that something.
I have 4-5 tables of single and many rows per ID. I want to generate a summary table listing each ID along with various counts and max/mins, but I want to be able to filter on calculations. Example: "ID" is the identifier and there are two tables, TestA and TestB.
One desired selection criteria: Show only those IDs where at least one TestA score >5 and there is at least one TestB score.
In a straight table, this is simple to do with expressions, but the resulting table cannot be selected on the calculated true/false value.
I think I need to create a new table in the load script containing the ID, and then various conditions labeled as I wish. Then, these fields could be dimensions. This seems similar in concept to a master calendar. Am I on the right track?
If it helps to understand my example, this a medical application; the tables are lab results and other interventions that each require complex queries pulling data from various sources that are very "hard-coded" to produce a small data set from millions of rows of highly normalized source data. The desired dimensions would be combinations of the labs so as to allow identification of patients who meet certain criteria--then, once filtered, there would be many more graphs and charts to identify what tests and procedures were followed for that group of patients.
My current data model just loads many tables which then associate on ID. I had attempted to load all data into one big table using concatenates and calculations, but this did not seem to accomplish what I needed and was difficult to manage.
IIUC, I think what you want to do can be accomplished with a combination of sliders/input boxes, variables and calculated dimensions in your table. The process is definitely burdensome, but it should allow you filter the way you want.
Add a field to your table load statement in your script like rnum as RowNo().
Create a variable for your filter(s). Ex. vFilterTestAScore.
Add a slider or input box to your dashboard and point it to that variable.
a. For slider, the option is in the General tab -> Data header -> select the Variable radio button.
b. For input box, add the correct var from the list to the list of Displayed Variables.
Set sliders/input boxes to the criteria you want: vFilterTestAScore = 5 and vFilterTestBScore = 1
Create a straight table with ID as the dimension and expressions for TestAScore and TestBScore. The expression formulas would be sum(TestAScore) and sum(TestBScore) respectively (this won't make sense until the next step).
Now add a calculated dimension to you table. The idea here is that rather than just having the ID dimension, you will create a calculated dimension that only displays the ID of the records that meet the criteria you select in the slider or enter in the input box. The formula should be something like:
if(aggr(sum(TestA), rnum) >= vFilterTestAScore, ID, null()) or for multiple filters: if((aggr(sum(TestA), rnum) >= vFilterTestAScore) and (aggr(sum(TestB), rnum) >= vFilterTestBScore), ID, null()).
On your new calculated dimension, check the 'Suppress When Value is Null' box so only results that meet your criteria are displayed in your table.
To summarize, you are using the variables to store your selection criteria which you are entering via input box or slider. Then you are conditionally displaying only the ID's in your table that match those criteria via a calculated dimension and 'Suppress When Null' option.
I can send you a .qvw if you aren't using the free personal edition and are able to open other qvw's.
I have a temporary table that is created from a series of query with a VBA code. The name and number of fields in the table changes with the results of the queries.
Right now I simply open the table with DoCmd.OpenTable.
What I would like to do is display the table in a form so I can include some buttons for example to allow the user to export the table.
I tried a listbox but the formatting was not good and I can't add horizontal scroll bar to see all fields.
I tried a subform populated from the table, but it would not adapt to the changes of the table (fields and numbers).
Any Idea of what can I do next ?
the subform seems to be a good idea. When your table is ready to be shown, you can assign it to a subform object via Me.subFormName.SourceObject = "Table.tableName"
(of cource "subFormName" and "tableName" have to be replaced by the actual names of the subform and the table)
I am using webdriver to test our application that contain table where the user can change the order of columns in a table,and also can remove/add columns (This is beside new column added by developers).
What is the right way to find the column I need?
One way is to go over the table header to find the column I am looking for so I have the column index and than I can access the right cell.
Is there other way ?
What about put unique id/class name for every element in table ?
Thanks
You can do two things for this situation:
Get handle to table element, and then navigate accordingly to get the columns or rows. Once you have this, then you can do all operations on them like click() etc.
Other way is, see the pattern of their ids/css because, most of the table that I have deal with will be having ids like this:
grid_name_1
grid_name_2
grid_name_3
Then you can have do this way:
String baseLocator = "grid_name_" + clickedRowIndex;
driver.findElement(By.id(baseLocator)).click(); //for click operation
Lets say user wants to click on the 3rd row, then clickedRowIndex will be 3 which selects the 3rd table row.
For a database with this schema (a product may belong to one or more categories):
Item_category(product, category_name)
Category(category_name)
Will it be possible for me to build a multi-selection list box (List box data source from the Category relation) using an Access form and then highlighting the categories that the product belongs to (by querying the Item_category table), and at the same time letting users select new categories or deselect highlighted categories so that when an "Update" button is pressed, VBA code will automatically determine either INSERT, UPDATE or DELETE queries are needed to update the Item_category table?
How can I do that? Thanks!
I've generally done this type of interface using a form which looks very much like the "Which fields do you want on your form?" in the Form Wizard. Where you have the Table/Query list of Available Fields in the table in the listbox on the left hand side and the Selected Fields in the listbox on the right hand side. Along with the move left and right command buttons in the middle. The users quite like this interface.
Added: Note that the left hand listbox contains all the category records which aren't present in the products category table. So a category would be present in one or the other listbox but never both.
You very likely will want to use the Multi Select property of the listbox. If you hit the help on that field in the property sheet it should lead you to a page which mentions the ItemsSelected collection. Visit that page for sample code on how to read all the items selected by the user. Or visit http://msdn.microsoft.com/en-us/library/aa196172%28v=office.11%29.aspx.
