LibSQL+SQLServer: Implement first cut of SELECT ... ORDER BY foo
Ordering is done by replacing the straight Vector holding the query result in the SQLResult object with a dedicated Vector subclass that inserts result rows according to their sort key using a binary search. This is done in the ResultSet class. There are limitations: - "SELECT ... ORDER BY 1" (or 2 or 3 etc) is supposed to sort by the n-th result column. This doesn't work yet - "SELECT ... column-expression alias ... ORDER BY alias" is supposed to sort by the column with the given alias. This doesn't work yet What does work however is something like ```SELECT foo FROM bar SORT BY quux``` i.e. sorted by a column not in the result set. Once functions are supported it should be possible to sort by random functions.
