Problem Note 37074: Query performance is slow on RPO_PLAN_MEMBER table joins
 |  |  |  |  |
You might observe slow performance in SAS® Regular Price Optimization, when running the following query:
select pm.rpo_plan_sk,
pm.prod_hier_sk,
pm.geo_hier_sk,
pm.effective_dt as start_dt,
pm.user_price,
rl.suggested_price
from DI_DM.rpo_plan_member pm
left join DI_DM.rpo_plan_member_result rl
ON pm.rpo_plan_sk = rl.rpo_plan_sk
and pm.geo_hier_sk = rl.geo_hier_sk
and pm.prod_hier_sk = rl.prod_hier_sk
AND pm.rpo_plan_sk = COALESCE (pm.rpo_plan_sk , pm.rpo_plan_sk)
AND pm.prod_hier_sk = COALESCE (pm.prod_hier_sk , pm.prod_hier_sk)
WHERE pm.approval_status_cd = 2
and pm.effective_dt >= Date('2006-07-02')
AND pm.approval_status_cd = COALESCE(pm.approval_status_cd,
pm.approval_status_cd)
Additional indexes on the RPO_PLAN_MEMBER table will increase performance significantly.
