It is a typical behaviour, that quoting depends
on the database type. For example, Oracle or Adabas D
will refuse a query like

   SELECT * FROM foo WHERE integer_column = '1'

because the single quotes are reserved for String types.
That is the reason, why DBI allows a second parameter
for $dbh->quote().

For example, in the above example you would need to

write

   $query = "SELECT * FROM foo WHERE integer_column = "
     . $dbh->quote(1, DBI::SQL_INTEGER);

With placeholders, however, the database cares about
the column type.
