In version 10.0.0 and earlier of UltraLite, the primary key was used to return results when no other index was used by the UltraLite optimizer. As a result, rows were ordered according to the order of the primary key index.
If your results must be ordered by primary key, you should re-write your queries to include the ORDER BY clause. If it is impractical to sort your rows with this clause, you can consider using the ORDERED_TABLE_SCAN connection parameter.
It is recommended that you use the ORDER BY clause whenever possible.
