Power Query Sugar for selecting distinct filters. If the condition is not true, then it throws an error. Name = "Orders" works because it results in a distinct value from the column Name It’s valid even though the final query is many records. It’s the “distinctness” of the filter that is required to be true
Sometimes you’ll need to run a command with the same input with different logic. This can be a hassle using a slow command like Get-ADUser or Get-ChildItem on a lot of files like ~ (Home) with -Depth / -Recurse
The only function that Power BI is missing is Facebook.Graph (on my machine)
* This query checks for missing identifiers (which may be functions). ( You can filter by type if you convert #shared to a table instead of calling Record.FieldNames() )
Generating the list using #shared
To get a list of all identifiers (functions, variables, constants) I use the variable named #shared . Create a new blank query, then paste this
let
IdentifierList = List.Sort(Record.FieldNames( #shared ))
in
IdentifierList
I copy using Copy Entire List, then storing the results into a PowerShell variable. I Repeat the same with Power BI.
That’s more than I expected.
To find out exactly which functions are different, use the Power Shell operator -NotIn
# Find functions in PBI but not Excel
$MissingExcel = $PowerBI | ? { $_ -notin $Excel }
# Find functions in Excel but not PBI
$MissingPowerBI = $Excel | ? { $_ -notin $PowerBI }
The list of functions Power BI is Missing
Facebook.Graph
The list of functions Excel is Missing
Note: This is the list for today, on my machine. Run the #shared query to find any changes.
ForEach-Object ( Note: this is a command, not a control loop )
It’s first argument is a ScriptBlock so it appears like a control loop.
Notice return verses break in ForEach-Object . Remember that the { ... stuff ... } in this case is an anonymous function , not a language control statement It is a parameter to the ForEach-Object . When not specified, it’s the -Process Parameter
