I have a table with with 2 columns:id(of a movie) and actor_name. For each id, there can be multiple actor names.
I want to add a new column with an index specific for each actor.
My table look like this:
Id.......actor_name
5........Al pacino
6........Tim Roth
7........Antonio Banderas
8........Al pacino
And I want it to look like this:
Id.......actor_name..............actor_number
5........Al pacino.................. 1
6........Tim Roth....................2
7........Antonio Banderas......3
8........Al pacino...................1
I'm doing this in power BI. I have a table with each actor and a specific index, but I can't make the connection between them because I don't have unique values in the the actor_name column.
Thank you in advance!
I would resolve this in the Query Editor/ Power Query. First I would build a query (lets call it Actor Index) by Reference to your "table with each actor and a specific index". I would either use Remove Rows / Remove Duplicates or Group By to ensure there are unique values for each actor_name.
Then over in your "My Table" query, I would add Merge and Expand steps to join to the new Actor Index and return the Index.

In Power BI, I need to create a VLOOKUP alternative. From the research I've done, this is done with the LOOKUPVALUE function, but the problem is that function needs one specific SEARCH ITEM, which isn't super helpful in a VLOOKUP type scenario where you have a full column of values to search for?
Given these two tables, connected through the user_name and first_name columns:
...what's the formula needed in order to create a new column in the Employee_Table called phone_call_group by using the names as the search items in order to return the group they belong to? So how can I end up with this?
(Forget that the entries in each table are already sorted, needs to be dynamic). Will be back tomorrow to review solutions.
In Power BI you have relations between tables instead of Excel's VLOOKUP function.
In your case you just have to create a one-to-one relation between
'Phone_Call_Table'[user_name] and 'Employee_Table'['first_name]'
With that you can add a Calculated Column to your 'Employee_Table' using the following expression:
phone_call_group = RELATED(Phone_Call_Table[group])
and in the data view the table will look like this:
LOOKUPVALUE() is just a workaround if for other reasons you can't establish that relation. What you've been missing so far is that in a Calculated Column there is a Row Context which gives you exactly one value per row for the <search_value> (this is different from Measures):
alt_phone_call_group =
LOOKUPVALUE(
Phone_Call_Table[group],
Phone_Call_Table[user_name],
Employee_Table[first_name]
)
I am stuck while dynamically forming a new column based certain WHERE clause from another Table in PowerBi. To give more details, let's say I have a table with item numbers associated with a Customer Name. In another table, I have to add a new column, which will dynamically add the item numbers associated with a particular customer and append as a query parameter to a base url.
So, my first table looks like this:
The second table that I want is this:
The query parameter value in the URL, has to be dynamically based on a SELECT query with a WHERE clause and pick up the ItemNumbers using the Customer field which is common between both. So, how can this be done in PowerBi? Any help would be really appreciated :)
I have one table in my model "TableRol" if I want to summarize my Date as the string I can use CONCATENATEX;
URL = CONCATENATE(CONCATENATE("http:\\mysite.com\parametersHere\getitem?='",CONCATENATEX(VALUES('TableRol'[Date]), 'TableRol'[Date],";")),"'")
I have my data source something like below.
I need to show output in the report as below.
I tried using the unpivot column and getting something like this, how to count the occurrence value of each Business value.
Plot following mesure against Value column (from your unpivot table):
Business Occurance = COUNTROWS('your unpivot table')
We have to remove the Attribute column as the next step to Unpivot. Then my table should be looks like this.
Now create a new table with following Dax function, let's say the current table as Business Data (Your Unpivot table)
Occurrence Table = DISTINCT('Business Data')
Now end result table should look like this,
You can make use of this table for your table visual in the report.
Note: You can add n-number of rows and column into your source table and this logic will do magic to get the correct result.

I'm using the following: dynamodb2, boto, python. I have the following code for creating a table:
table = Table.create('mySecondTable',
schema=[HashKey('ID')],
RangeKey('advertiser'),
throughput={'read':5,'write':2},
global_indexes=[GlobalAllIndex('otherDataIndex',parts=[
HashKey('date',data_type=NUMBER),
RangeKey('publisher', date_type=str),
],throughput={'read':5,'write':3})],
connection=conn)
I would like to be able to have the following data that I can query by:
ID, advertiser, date, publisher, size, and color
That means I need a different schema. When I add additional points it does not query unless the column name is listed in the schema.
The problem however is that right now I am only able to query by Id, advertiser, date, and publisher in this case. How can I add additional columns that I can query by?
I read this which appears to say that it is possible:
http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/GSI.html
However there is no example here:
http://boto.readthedocs.org/en/latest/dynamodb2_tut.html
I tried adding an additional range key however it doesn't work (cannot have duplicates)
I'd like it to be like:
table = Table.create('mySecondTable',
schema=[
RangeKey('advertiser'),
otherKey('date')
fourthKey('publisher') ... etc
throughput={'read':5,'write':2},
connection=conn)
Thanks!
If you want to add additional range keys you need to use Local secondary index.
You can query the LSI in the same way that you query the base table. You need to provide an exact value for the hashkey and a comparison-predicate for range key.
I have two questions:
I have two tables, table1 and table2. I need to design an application in such a way that a selected row of table 1 when clicked should get displayed in table 2.
How do I call a custom table? Suppose I have a class Table with empty constructor and I will pass arguments like Table(pagination). It has to show the table with pagination,
Similarly, Table(lazyloading) has to show lazy loading table. Table(pagination, Lazy loading,search) must show all three properties.
What you have to do for nr 1 is that you attach a Clicklistener to your table1 and on a Clickevent you take the selected Object ni table1 and add it to table2. Also add an if to not add rows that already exist in table 2.
This is how you copy data
public void copydata(){
Object o = table1.getValue();
if(!table2.getItemIds().contains(o))
table2.addItem(o);
table2.setContainerDataSource(table2.getContainerDataSource());
}
When it comes to your second question I have no clue what you are talking about, but I looks like you want to extend the Table class in vaadin to get your own features.
