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

Question

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

public ResultSet execSumStatment2() throws SQLException{
String query = \"Select SUM(A) as NCCSeptemb         


        

Answer 1

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'
