Is there a way to use variables in calculated columns?

[theregister]

I know I can use calculated columns to do things like this:

Code: Select all

ColumnA - ColumnB

But what if I wanted to create variables asked from the user, to decide which columns I want in the calculation like this:

Code: Select all

Variable1:B , Variable2:C

Thus, allowing me to do this:

Code: Select all

Column{Variable1} - Column{Variable2}

Thus calculating in the calculated column only the columns the user selected while on the preview tab.

I know I can kinda concatenate column names like this on the SQL code, but is there a way to do it from here?
