Change date on select statement

Question

Hi all,
I've field CLOSEDATA datatype DATA format 'dd/mm/yyyy hh:mm'
I extract CLOSEDATA with this query
SELECT CLOSEDATA
FROM JAVADEV
WHERE CLOSEMONTH='2010'but don't want the extracted time hh:mm of CLOSEDATA... I want to change it into 02:00
So the output of my query will be 'dd//mm/yyyy 02:00'
How do I change the previous query??
Thanks in advance

Do you mean "datatype VARCHAR2"? Then just ignore the last 5 characters, and substitute whatever you want instead:
SELECT  SUBSTR (CLOSEDATA, 1, 11) || '02:00'     AS clesedata
FROM    JAVADEV
WHERE   CLOSEMONTH = '2010' 
If closedata were a DATE, then
{code}
TRUNC (closedata) + (2 / 24)
{code}
would be 02:00 on the same day, regardless of what the original hours and minutes were.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using.
