Is there a function in Power BI that can check whether a list of specified values (numbers) exists in a column?
For example, in the image below, I have a column with some values and another one with 0 and 1s. You can see that some values are marked with 1 and some with 0. In order to do this, I used IF function, but this is just too cumbersome.
I am looking for a formula that can check if the values from a list like {XXXX, XXXX, XXXX, etc} exist in a column and that can easily be edited when I need to add other values.
Thank you and have a good day!
Best,
Denis
You can do that by adding a custom column for example. If we assume your table is named Table and first column is named Value, then add a custom column like this:
Where the list contains all the values of interest. This will give you a boolean column Flag:
If you want an integer column with 0 and 1 values, then change the column to something like this:
= if (List.Contains({"5006", "4905"}, [Value])) then 1 else 0

Say I have a column with Text data like:
A
B
A
D
I would like to create a new column so that the end result is:
A 0
B 1
A 0
D 2
What is the correct way do this is PowerBI Power Query Editor? I tried a few things like indexing but that gives a unique value to every row. Not very familiar with the API so am a bit stuck here.
We can do something like: List.PositionOf(List.Distinct(Table.Column( #"Table name", "Col")), [Col]))
where Col is the column name.
Having imported an excel sheet into power query, I need to tidy it up by changing the value of a particular cell.
At the moment that cell has a null value, but there are other null values in the same column that I do not want to change. – So I cannot replace all of the null values in that column with another value.
I also cannot correct that particular cell in the source excel file (there are hundreds of them, which were created before I arrived).
I basically need some syntax for example that sets the value of cell H2 to “Jeep”, but not to change any other cells.
Very grateful for any insight.
One way would be:
In the Power Query Editor:
Add an index column starting from 1 (tab Add Column)
Add a Conditional column: If [Index] = 2 then Jeep else [H] (tab Add Column)
Delete Index column and [H] Column
Rename Custom column to [H].
I have 2 column; ID CODE, value
Remove duplicates function will remove the examples with the higher value and leave the lower one. Is there any way to remove the lower ones? The result I expected was like this.
I've tried Buffer Table function before but it doesn't work. Seems like Buffer Table just works with date-related data (newest-latest).
You could use SUMMARIZE which can be used similar to a SQL query that takes a MIN value for a column, grouped by some other column.
In the example below, MIN([value]) is taken, given a new column name "MinValue", which is grouped by IDCode. This should return the min value for each IDCode.
NewCalculatedTable =
SUMMARIZE(yourTablename, yourTablename[IDCode], "MinValue", MIN(yourTablename[value]) )
Alternatively, if you want the higher values just replace the MIN function with MAX.
In Power BI Desktop, I'm trying to order the following column with repeated values by an ID column (contains primary key).
This returns the error: "There can't be more than one value in "Nível2"...."
In this other post it seems the suggestion is to concatenate the values of the column so they don't get duplicate.
But I want them to be repeated so they can aggregate values in visuals.
So, what's the workaround for this situation?
Thanks in advance for helping!
The issue is that your sort column (i.e. your ID column) contains multiple values for each value in the column you are trying to sort (i.e. your Nivel2 column).
You need to ensure that your sort column contains only one distinct value for each value in the column you are trying to sort.
One way to achieve this would be to create a new (calculated) sort column based on your ID column. It could be defined like this:
SortColumn:=CALCULATE(MAX('YourTable'[ID]),ALLEXCEPT('YourTable','YourTable'[Nivel2]))
Here is an example of how the SortColumn would behave:
Id Nivel2 SortColumn
1 Caixa 4
2 Caixa 4
3 Caixa 4
4 Caixa 4
5 Depósitos à ordem 7
6 Depósitos à ordem 7
7 Depósitos à ordem 7
You can now sort Nivel2 by SortColumn.
EDIT - The implementation of the SortColumn should be done in the data source
There seems to be a limitation in PowerBI where it checks the implementation of the sort column rather than the data in the sort column. Therefore the above solution does not work, even though the data in the sort column is perfectly valid. The above solution will throw this error when you attempt to sort [Nivel2] by SortColumn:
This column can't be sorted by a column that is already sorted, directly or indirectly, by this column.
The implementation of the SortColumn should be moved to the data source instead. I.e. if your data source is an Excel sheet, then the SortColumn should be created inside the Excel sheet.
The above answer does explain the issue and the resolvation correctly. The only change is that the SortColumn must be implemented outside of the tabular model (PowerBI) to ensure that PowerBI does not know about the dependency between the SortColumn and the [Nivel2] column.
In my case, I calculate the levels from a parent-child hierarchy
Path = Path([id],[father])
For each level:
Level1 = LOOKUPVALUE([Name],[id], PathItem([Path],1))
Level2 = LOOKUPVALUE([Name],[id], PathItem([Path],2))
.....
Then I created a new column for each level to sort the column Level:
SortL1 = LOOKUPVALUE([nID],[id], PathItem([Path],1))
SortL2 = LOOKUPVALUE([nID],[id], PathItem([Path],2))
.....
id and nID is the same numeric variable but "id" in string format because Path do not support numeric values.
I am front end developer new to django. There is a certain column(server_reach) in our postgres DB which has values of (1,2). But I need to write a query which tells me if at least one of the filtered rows has a row with reachable values( 1= not reachable, 2 = reachable).
I was initially told that the values of the column would be (0,1) based on which I wrote this:
ServerAgent.objects.values('server').filter(
app_uuid_url=app.uuid_url,
trash=False
).annotate(serverreach=Sum('server_reach'))
The logic is simple that I fetch all the filtered rows and annotate them with the sum of the server_reaches. If this is more than zero then at least one entry is non-zero.
But the issue is that the actual DB has values (1,2). And this logic will not work anymore. I want to subtract the server_reach of each row by '1' before summing. I have tried F expressions as below
ServerAgent.objects.values('server').filter(
app_uuid_url=app.uuid_url,
trash=False
).annotate(serverreach=Sum(F('server_reach')-1))
But it throws the following error. Please help me getting this to work.
AttributeError: 'ExpressionNode' object has no attribute 'split'
Use Avg instead of Sum. If average value is greater than 1 then at least one row contains value of 2.
