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

2021-12-19 00:00:00 date select oracle ora-01830

我正在尝试通过 Java 执行我的查询,如下所示:

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);
}

然后我在类中调用execSumStatement:

Then i call execSumStatement in the class:

sql.execSumStatement2 () ;

当我运行它时,我收到以下错误消息:

When I run it I get the following error message:

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

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

当我在 SQL Developer 中执行相同的查询时,它工作得很好.我已经在互联网上进行了搜索,我猜问题是查询中日期的数据类型,应该是日期,但是我尝试的一切都不起作用......

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...

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!

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

推荐答案

我认为你不应该依赖隐式转换.这是一个不好的做法.

I think you should not rely on the implicit conversion. It is a bad practice.

相反,您应该像这样尝试:

Instead you should try like this:

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

或者喜欢

datenum >= date '2013-09-01'
