1. `sql/database` provides a `Scan()`interface to scan query results
into typed variables. Therefore we have to create a slice of typed
variables (types retrieved from rows.ColumnTypes()) to pass them into
`Scan()`. Using []byte works but makes the printing result different
from other tools (e.g [1] instead of %!s(int32=1)]
2. MS SQL supports both named (e.g @name) and positional args (e.g @p2),
so we have to check if the name is contained in the original statement
before passing them into `db.Query()` as either named arg or as values.
