CREATE TABLE B
AS
SELECT * FROM A
ORDER BY ROWNUM DESC;

Answer / priyank

In Informatica, make table A as Source and follow the below
mapping:

SRC_A --> AGG --> TGT_B

AGG: Do not check any of the columns for group by and pass
the output to target B. In this way, only the last row will
be passed through.
