ORA-01830:日期格式图片在转换整个输入字符串之前结束/选择日期查询的总和

Question

我试图通过Java执行我的查询,如下所示:

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);
}

然后我在类中调用execSumStatement:

sql.execSumStatement2 () ;

当我运行它时,我收到以下错误消息:

java.sql.SQLDataException:ORA-01830:日期格式图片在转换整个输入字符串之前结束

当我在SQL Developer中执行相同的查询时,它工作得很好.我已经通过互联网进行了搜索,我猜问题是查询中日期的数据类型,应该是Date,但我尝试的所有内容都不起作用...

我是编程的初学者,所以如果你能尽可能简单地解释它会很棒!提前致谢!

Answer 1

我认为你不应该依赖隐式转换.这是一个不好的做法.

相反,你应该尝试这样:

datenum >= to_date('11/26/2013','mm/dd/yyyy')

或者喜欢

datenum >= date '2013-09-01'

Answer 2

你可以试试这个:

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;
