下面的是oldwain(老斗)的方法:
CREATE or replace JAVA SOURCE
NAMED MyTimestamp
AS
import java.lang.String;
import java.sql.Timestamp;
public class MyTimestamp
{
public static String getTimestamp()
{
return (new
Timestamp(System.currentTimeMillis())).toString();
}
};
create or replace function my_timestamp
return varchar2
AS LANGUAGE JAVA
NAME 'MyTimestamp.getTimestamp() return java.lang.String';
select my_timestamp,to_char(sysdate,'yyyy-mm-dd hh24:mi:ss') from dual;
