I am trying to execute my query through Java like this:
public ResultSet execSumStatment2() throws SQLException{
String query = \"Select SUM(A) as NCCSeptemb
In SQL Developer ..Go to Preferences-->NLS-->and change your date format accordingly
You can try this:
Select To_date ('15/2/2007 00:00:00', 'DD/MM/YYYY HH24:MI:SS'),
To_date ('28/2/2007 10:12', 'DD/MM/YYYY HH24:MI:SS')
From DUAL;
Source: http://notsyncing.org/2008/02/manipulando-fechas-con-horas-en-plsql-y-sql/
You can use
Select to_date('08/15/2017 12:00:00 AM','MM/DD/YYYY HH:MI:SS AM') from dual;
If you are using it in an SP then your variable datatype should be Varchar2
and also in your ado.net code the datatype of your input parameter should be
OracleDbType.Varchar2
Basically I had to put a DateFrom and DateTo filter in my SP so I passed dates as String in it.
Note: This is one of the solution which worked for me, there could be more solutions to this problem.
What you have written in your sql string is a Timestamp not Date. You must convert it to Date or change type of database field to Timestamp for it to be seen correctly.
You can try as follows it works for me
select * from nm_admission where trunc(entry_timestamp) = to_date('09-SEP-2018','DD-MM-YY');
OR
select * from nm_admission where trunc(entry_timestamp) = '09-SEP-2018';
You can also try using to_char but remember to_char is too expensive
select * from nm_admission where to_char(entry_timestamp) = to_date('09-SEP-2018','DD-MM-YY');
The TRUNC(17-SEP-2018 08:30:11) will give 17-SEP-2018 00:00:00 as a result, you can compare the only date portion independently and time portion will skip.
I think you should not rely on the implicit conversion. It is a bad practice.
Instead you should try like this:
datenum >= to_date('11/26/2013','mm/dd/yyyy')
or like
datenum >= date '2013-09-01'
