ORA-01830: date format picture ends before converting entire input string / Select sum where date query

I am trying to execute my query through Java like this:

public ResultSet execSumStatment2() throws SQLException{
String query = "Select SUM(A) as NCCSeptember from NCC where Datum >= '01-09-2013 00:00:00' and Datum <= '30-09-2013 23:59:59'";
return execStatement(query);
}

Then i call execSumStatement in the class:

sql.execSumStatement2 () ;

When I run it I get the following error message:

java.sql.SQLDataException: ORA-01830: date format picture ends before converting entire input string

When I execute the same query in SQL Developer it works just fine. I already made a search over the internet, and I guess the problem is the datatype of the date in the query, which should be Date, but everything I tried didn't work...

I'm a beginner in programming so it would be great if you could explain it as simple as possible! Thanks in advance!

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'

heythere

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;

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.

In SQL Developer ..Go to Preferences-->NLS-->and change your date format accordingly

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.

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');

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.
