Using DAX to get a table from nested table - dax

In powerBI, I using the python script and generate one table. The generated table is a nested table. Each row value is actually a table. and so now I want to use DAX to copy one specific row value(which is a table), just the "dataset_filtered" table shown as below.
what's the DAX code for this ? or any good suggestions ?
The nested table

This is M rather than DAX.
Click the drop down arrow in the name column to filter the row you want.
Click the expand arrows in the Value column to expand the table.

PowerBI - Lookup by Multiple Criteria

I'm a new PBI user and would like help on the following:
I have 2 tables (Table 1 & 2). Table 1 is a bookings report showing sales orders, part numbers and order value. Table 2 is a margin report showing sales orders, part numbers with additional descriptive text and margin value.
I would like to copy margin values from Table 2 into a new column in Table 1 by looking up by sales order and part number.
Any help would be appreciated!
Tables1
Extract text using the LEFT function
Use the COMBINEVALUES function to create new column in each table. The new column will merge two existing old columns.
Depending if you have unique values in the lookup table, use LOOKUPVALUE function, if not, use this approach: DAX lookup first non blank value in unrelated table

How to visible only the last row of a row group of a table in ssrs report

I have a table in SSRS report. And I need to display only the last row of the table. ie,
How can I do this?
How do I select last 5 rows in a table without sorting? see this post, and change to "-1"
We can select the last row of the table by using Last() method.
For eg. if we have a table called Test then,
Last(Fields!Test.value);

Oracle apex report View

Can I create a report like the below screenshot?
This is being a challenge to create cascaded column like some columns will be grouped into specific parent column.
You can try pivoting the interactive report ([Actions]->[Format]->[Pivot]) with two columns as Pivot columns.
It will group Parent and Child columns like in the example.
The limitation is to show only numeric data though.

Delete columns from BIRT report

I have a BIRT Excel Report with 10 columns. I have a query which executes and brings the data for all the 10 columns.
However, based on one of the input parameters, i need to display just 8 columns. I am able to hide the remaining 2 columns but i would like to delete those 2 columns from the report so that user does not see the hidden columns.
I tried to change the query but i am unable to dynamically set the select parameters.
Is there a way either in Query or in BIRT to remove few columns based on an input condition.
You cannot delete the columns, but it's sufficient to hide them dynamically using the column's visibility expression. You can add an aggregation to the table, using the MAX function for the column data (let's call it max_name).
E.g. if your table column shows the DS column NAME and you want to hide the column if NAME is empty for all rows:
Add an aggration (let's call it MAX_NAME) to the table, with the aggregation function MAX and the expression NAME. Then in the visibility expression of the table column, use !row["MAX_NAME"] as the expression.
After drag and drop the dataset. Right click on column header and select the delete column option.

how to hide an external table when there is no data in internal table in BIRT?

I have two tables one inside the other. When there are no detail rows in the inner table i am making it invisible. but i am not able to make the external table invisible.
In detail My inner table heading row and footer is visible even when there are no detail rows so i made the table visibility to true when no detail rows. But i am not able to make the external table invisible with the same logic. it is because even though the inner table is invisible the detail and footer is there so when i say no detail rows no visibility it is not working. so how can i hide the external table when the internal table is invisible?
I would try Binding the data set to the external table and making an aggregation that counts the number of rows in the data set.
Click on the Table
go to Binding in the Property Editor
click Add Aggregation
I called the Column Binding Name RowCount and set the Function to COUNT. Set the Expression to one of the columns from your dataset that you have included in the binding. In my case, I set Expression to row["columnname"].
Click on your table.
go to Visibility in the Property Editor.
check Hide Element and set the Expression to:
row["RowCount"]==0 || row["RowCount"]==null
The element will only display when the RowCount aggregation counts more than 1 row in your dataset.
My solution for this was to create a function that counts the records that meet the desired criterion, in my case select count(*) from my_table where user_id = id.
Then I inserted this function as a detail component that gets the count based on the selected table record.
Then I used the result of the count as a visibility rule. count > 0. this way I can hide the tables that return empty.
Using this trick is possible to hide the secondary table but the count details component will be still there, if you want to hide it you have to put it in a flexbox component. then in the visibility rules you an access you flexbox component and include the rule count > 0
