Delete the quotes around %?.

It is not considered safe to use concat and ParseWithParams at the same time. Though this case is safe.
fmt.Sprintf(fmt.Sprintf("%s", "%s")) will report an error.

I suggest that you can use fmt.Fprintf.

Just let you know, we have fmt.Fprintf in our errcheck_ignore lists. And I agreed with that. fmt.Fprintf can not throw error on valid input, unless OOM. So you do not need to check that error.
BTW, You could use Fprintf to concat idList & nameList too.
