A multiprocessing uncompression mechanism takes advantage of existing multiprocessing capability within a database to perform dynamic uncompression of portions of a partially compressed database table that satisfy a query using processes that may be executed in parallel. Historical information is gathered for each query. Uncompression advice includes user-specified parameters that determine how the multiprocessing uncompression mechanism functions. The multiprocessing uncompression mechanism processes the historical information and uncompression advice to determine an appropriate task count for performing uncompression in parallel processes. The existing multiprocessing capability within the database then processes the tasks that perform the uncompression in parallel.
