Abstract
A query to perform an ordered analytic function contains a clause specifying creation of dynamic partitions, where the clause contains a partitioning condition to specify the dynamic partitions. During processing of the query, dynamic partitions are identified based on evaluating the partitioning condition. To identify the dynamic partitions, a first table is created that contains a first column to track rows of an input table for indicating whether the partitioning condition evaluates to true. The first column of the first table is used to identify the dynamic partitions.
