PERFORMING BATCHES OF SELECTIVE ASSIGNMENTS IN A VECTOR FRIENDLY MANNER

摘要

Embodiments of the invention relate to processing queries. A query operation to be performed on a table of data is translated into a series of bit level logical operations using expansion and/or saturation operations. A mask is created from the series of bit level logical operations. This mask is then simultaneously applied to multiple rows from the table of data.
