I am new to Oracle DB and have a situation in hand.
I have two tables.
Table1 [ ID, MY_DATE ]
Table2 [ ID, MY_TIMESTAMP]
I need to pick the month alone from Table1.MY_DATE and replace the corresponding month at Table2.MY_TIMESTAMP.
Both Table1 and Table2 are joined by ID.
How do I pick the month alone from a Date column and replace month alone in a TimeStamp field.
Can anyone please help?
UPDATE SO_BUFFER_TABLE_13 BT2
SET BT2.MY_TIMESTAMP = TO_DATE((TO_CHAR(BT2.MY_TIMESTAMP, DD ) || / ||
(SELECT TO_CHAR(BT1.MY_DATE, MM )
FROM SO_BUFFER_TABLE_12 BT1
WHERE BT1.ID = BT2.ID) || / ||
TO_CHAR(BT2.MY_TIMESTAMP,
YYYY HH:MI:SS AM )),
DD/MM/YYYY HH:MI:SS AM )
