How to use a parameter in an expression in M
I want to dynamically change a variable and use it to filter rows.
let
Variable = "ABC",
Source = anything,
#"Filtered Rows" = Table.SelectRows(source, each Text.Contains([FilterColumn], "ABC") )
in
#"Filtered Rows"
works where [FilterColumn] is a column returned in the source query.
What I want to do is something like:
#"Filtered Rows" = Table.SelectRows(source, each Text.Contains([FilterColumn], Variable) )
so I can change the variable based on something else and get different results.
However, nothing I try seems to work. There must be a way to dynamically build an expression.
Amy Ideas?
How are you applying it ?
I just tried it with a custom column and it worked.
let _variable = "A" in Table.SelectRows(#"Changed Type", each Text.Contains([Value], _variable))

I was trying to build part of the expression in the variable but, once I saw your post, it seemed obvious.
Thanks
