<

Answer 1

try this type of format:

SELECT to_char(sysdate,'dd-mm-rrrr') FROM dual

Answer 2

Convert Timestamp to Date as mentioned below, it will work for sure -

select TO_DATE(TO_CHAR(TO_TIMESTAMP ('2015-04-15 18:00:22.000', 'YYYY-MM-DD HH24:MI:SS.FF'),'MM/DD/YYYY HH24:MI:SS'),'MM/DD/YYYY HH24:MI:SS') dt from dual

Answer 3

Use the function cast() to convert from timestamp to date

select to_char(cast(sysdate as date),'DD-MM-YYYY') from dual;

For more info of function cast oracle11g http://docs.oracle.com/cd/B28359_01/server.111/b28286/functions016.htm#SQLRF51256

Answer 4

In Oracle 11g, To get the complete date from the Timestamp, use this-

Select TRUNC(timestamp) FROM TABLE_NAME;

To get the Year from the Timestamp, use this-

Select EXTRACT(YEAR FROM TRUNC(timestamp)) from TABLE_NAME;

To get the Month from the Timestamp, use this-

Select EXTRACT(MONTH FROM TRUNC(timestamp)) from TABLE_NAME;

To get the Day from the Timestamp, use this-

Select EXTRACT(DAY FROM TRUNC(timestamp)) from TABLE_NAME;

Answer 5

This format worked for me, for the mentioned date format i.e. MM/DD/YYYY

SELECT to_char(query_date,'MM/DD/YYYY') as query_date 
FROM QMS_INVOICE_TABLE;

Answer 6

If you want the value from your timestamp column to come back as a date datatype, use something like this:

select trunc(my_timestamp_column,'dd') as my_date_column from my_table;
