Tara, aralin natin ang window functions sa PostgreSQL! Sa video na ito (70) ipapakita kung paano gamitin ang OVER() kasama ang RANK() at DENSE_RANK() sa psql — praktikal sa terminal at workflows. Perfect para sa mga Pinoy devs at DBAs na gustong mag-level-up! #PostgreSQL #SQL #WindowFunctions #RANK #DENSE_RANK #psql #Linux #Pinoy #Tagalog
