Is it possible to use parameters in lookup column?
For example,
```SQL
PARAMETERS(groupLabel VARCHAR DEFAULT 'mice')
SELECT participantid.groupLabel
FROM Demographics
```
where participantid.mice exists

No. Parameters can be used in place of static strings or integers that would otherwise be embedded in the SQL, but not to swap out identifiers like table or column names.
