'Row Number () Partition By' syntax problem - response (8) by dnoeth

Well, the "ultimate solution" in this case would use QUALIFY instead of a Derived Table and WHERE :-)

SELECT *
FROM DW_NLIP_PRV_PLNS
QUALIFY
  ROW_NUMBER () 
  OVER (PARTITION BY Subscription_Id ORDER BY Wrls_Prod_Eff_Dt DESC) = 1;
