The problem is that you've got local variables shadowing the field names
you want to use. What the SQL engine sees from that is

SELECT Symbol, $1, $2, $3
FROM TestBug WHERE Date=$4
ORDER BY $5 DESC

and it just assigns random ?columnN? names to the record columns (which
are going to have useless empty-string values anyway).

Use different local variable names, or qualify the field references in
the SELECT, eg TestBug.RS03.
