Using sql with ternary op doesn't work in Tableau

Using sql with ternary op doesn't work in Tableau - Questionmark(?) is treated as unnamed binding parameter.
Example:
_Select (1 = 2 ? 3 : 4)_
is translated into
_select (1 = 2 {odbc_positional_1:Nullable(Nothing)} 3 : 4)_

Replacing it with 'if' is a valid workaround but we have quite a lot big SQL reports using ternary op already.
What's your view on this? Can it be fixed by distinguishing ternary from binding parameter?

Start by reproducing the ternary expression through Tableau and the ODBC driver, then trace how question marks are identified as binding parameters. Verify the behavior against the example in the issue while checking that ordinary parameter binding still works. Done means ternary SQL is passed through correctly without breaking positional parameters.
