<p rev="" id="analytic_partition_pruning_caveat">
In queries involving both analytic functions and partitioned tables, partition pruning only occurs for columns named in the <codeph>PARTITION BY</codeph>
clause of the analytic function call. For example, if an analytic function query has a clause such as <codeph>WHERE year=2016</codeph>,
the way to make the query prune all other <codeph>YEAR</codeph> partitions is to include <codeph>PARTITION BY year</codeph>in the analytic function call;
the way to make the query prune all other <codeph>YEAR</codeph> partitions is to include <codeph>PARTITION BY year</codeph> in the analytic function call;
for example, <codeph>OVER (PARTITION BY year,<varname>other_columns</varname> <varname>other_analytic_clauses</varname>)</codeph>.
