The ordering is hierarchical.
For example, ORDERBY=(A, B) specifies ordering by the values of column
B within the ordered values of column A. The order is determined based
on the raw value of the columns and uses locale-sensitive collation
for character columns.
By default, column values
are arranged in ascending order. You achieve descending order by specifying
the keyword DESCENDING or DESC after the column name in the column
list.
