compare_keys
and compare_rows_if_equal_keys
are comparison functions used to
compare rows in a table in order to sort them.
compare_keys
compares two rows based on a single column in the table's sort
criteria.
compare_rows_if_equal_keys
compares two rows based on their row ids, and is only
called if the calls to compare_key
for all columns in the table's sort criteria
return 0. The sort direction is determined by the first column in the sort criteria.
