Hi
I can solve requests(SQL-query) of any complexity and function fibonacci/player_height_rank
An expert on database optimization, this is mainly what I’m doing now - more than half the time, reports, setting up indexes, hints, plans. Rewriting queries, partitioning tables, changing the type of tables (from the heap to something else). Mostly optimization of OLTP (fast transactions) systems, less often for DWH (storefronts).
