Hi Hive Team, I have Teradata Query as below and my intention is to convert in to Hive Query(HQL). Tried but it's vain.
SELECT Col_1, Col_2, Col_3, MIN(Col_3) OVER(Partition by Col_1 ORDER BY Col_3, Col_2 rows between 1 preceding and 1 preceding) prev_Col_3 FROM work_table ; Example: Actual Work table: Col_1 Col_3 Prev_Col_3 P1 9:00 Null P1 10:00 Null P2 11:00 Null P2 12:00 Null Expected result: Col_1 Col_3 Prev_Col_3 P1 9:00 Null P1 10:00 9:00 P2 11:00 Null P2 12:00 11:00 Any help will be much help full.
