 * The limit-subquery-algorithm needs to execute to subquery separately in mysql, since mysql doesn't yet support LIMIT clause in subqueries

 * Oracle only allows < 30 object identifiers (= table/column names/aliases), hence the limit subquery must use as short aliases as possible and it must avoid alias collisions with the main query.

 +++ The limit-subquery-algorithm
 
 The limit-subquery-algorithm is an algorithm that DQL parser uses internally when one-to-many / many-to-many relational data is being fetched simultaneously. This kind of special algorithm is needed for the LIMIT clause to limit the number of records instead of sql result set rows.
