I'm running Oracle 10g and have columns with Type_Name
TIMESTAMP(6) WITH TIME ZONE
When inflated into java classes they come out as
oracle.sql.TIMESTAMPTZ
But DbUnit can't handle converting Oracle specific classes to Strings for writing to XML. I'm wondering if there's any easy way for me to convert (say, in my SELECT statement somehow) from these Oracle specific timestamps to something in java.sql.
I haven't had to deal with this problem exactly, but I presume that having it come through as a string from the SELECT query would be fine.
You could use the to_char function. To convert it to a string. e.g:
SQL> select to_char(systimestamp, 'YYYY-MM-DD HH24:MI:SS.FF TZD') as d from dual;
D
----------------------------------
2008-10-21 17:00:43.501591
This would then be seen by your program as a string. TZD includes timezone information (of which there is none in this example)
Later, this could then be parsed by Java using the SimpleDateFormat class.
Alternatively, the oracle.sql.TIMESTAMPTZ class has a method called dateValue that returns a java.sql.Date class.
I would like to remark that using IYYY as format for the year might not be a good idea unless you really want to get the ISO year. You should use YYYY instead of IYYY.
Try to run your SQL for 31.12.2012 using
select to_char(timestamp'2012-12-31 00:00:00 +00:00', 'IYYY-MM-DD HH24:MI:SS.FF TZD') as d from dual;
returns "2013-12-31 00:00:00.000000000" which is not the year you would expect.
