Explanation

The RESULT_CACHE_MODE initialization parameter determines the SQL query result cache mode. The parameter specifies when a ResultCache operator is spliced into a query's execution plan. The parameter accepts the following values: The ResultCache operator is added to the root of all SELECT statements, if that is possible. However, if the statement contains a NO_RESULT_CACHE hint, then the hint takes precedence over the parameter setting. The ResultCache operator is added, only if you use the RESULT_CACHE hint in the SQL query.
