Using parameters in advanced editor

 

I'm wondering if I can replace a piece of code in the advanced editor with a parameter that contents the same piece of code on text value. For example, if I want to change the type of each column:

 

1) This is the line recorded by Power Query Editor, and I want to replace the bolded code with a parameter (because the numbers of columns can change, and also the columns name can change):

#"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers", {{""Etap"", Int64.Type}, {""Ser."", Int64.Type}, {""Bloq"", Int64.Type}}),

 

2) Then I create a text parameter, named Parameter1, with the following value:

 {{""Etap"", Int64.Type}, {""Ser."", Int64.Type}, {""Bloq"", Int64.Type}}

 

3) And try to replace the parameter in the advanced editor line (I'm not sure of the syntax):

#"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers", Parameter1),

 

4) But this error message is displayed:

Let me know if there is any other way to replace a piece of code with something else instead of a parameter. Mainly because I have a variable number of columns in a query.

 

Thank you in advance for your help.

Re: Using parameters in advanced editor

Hi @e17aguilar,

 

I don't think above attemption is achievable.

 

As you can see, the supported data type by Query Parameter are normal ones.

But, many times, the items wrapped by Power Query function are not listed in above data types. In your example, the second argument in Table.TransformColumnTypes function should be List type. While the value ({{""Etap"", Int64.Type}, {""Ser."", Int64.Type}, {""Bloq"", Int64.Type}}) you passed by parameter was forced to Text. They are not matched, hence caused errors. Especially, the long text wrapped by "{ }" cannot be passed as a parameter value.
