Oracle's 'Interval day to second' data type in Hibernate
Hi!
Has anyone implemented Hibernate access to a column in Oracle using 'Interval day to second' data type?
I've seen this link while searching Google.
http://www.oracle.com/technology/sample_code/tech/java/codesnippet/jdbc/intervaldaytosec/intervaldaytosecond.html#how1
But I'm clueless about how to implement it using Hibernate.
I guess this just worked:
<property name="sampleTime" type="oracle.sql.INTERVALDS">
<column name="acct_life_time" sql-type="interval_year_to_month" />
</property>Edit:
Uh oh. It works on an empty column. I got this error while trying to access one that's not:
INFO SerializableType:178 - could not read column value from result set: acct3_7_; could not deserialize
Exception in thread "main" org.springframework.orm.hibernate3.HibernateSystemException: could not deserialize; nested exception is org.hibernate.type.SerializationException: could not deserialize

Problem when summery the data type of interval day to second
hi
i write a program calculate periods of time and summary it then i used interval day to second data type
oracle support basic 4 math operation (+,-,*,/) on interval
but although oracle does not support summary function like sum() ,avg(),count()!! this is a problem here
the walkaround it by use oracle data cartdrage advanced future like follows steps :
*1- i create type and i call it for ex: DAY_TO_SECOND_SUM_TYPE*
CREATE OR REPLACE DAY_TO_SECOND_SUM_TYPE /*TYPE as object
+(TOTAL INTERVAL day to SECOND , /* type header*/+
STATIC FUNCTION ODCIAggregateInitialize(SCTX IN OUT DAY_TO_SECOND_SUM_TYPE) return number,
member function ODCIAggregateIterate( self in out DAY_TO_SECOND_SUM_TYPE,value in interval day to second) return number,
member function ODCIAggregateTerminate(self in DAY_TO_SECOND_SUM_TYPE,returnvalue out interval day to second , flags in number) return number,
member function ODCIAggregateMerge(self in out DAY_TO_SECOND_SUM_TYPE,ctx2 in DAY_TO_SECOND_SUM_TYPE) return number

member function ODCIAggregateMerge(self in out DAY_TO_SECOND_SUM_TYPE,ctx2 in DAY_TO_SECOND_SUM_TYPE) return number
+)+
create or replace type body DAY_TO_SECOND_SUM_TYPE as /* type body*/
static function ODCIAggregateInitialize(sctx in out DAY_TO_SECOND_SUM_TYPE) return number is
begin
sctx := DAY_TO_SECOND_SUM_TYPE(numtodsinterval(0,'second'));
return odciconst.Success;

*2- i create artificial function to summary using that type let as called for ex: ds_sum as follows :*
create or replace function ds_sum( input interval day to second ) return interval day to second
parallel_enable aggregate
using DAY_TO_SECOND_SUM_TYPE
+/+
at last i used the function to summary intervals and its work so good but when the result of calculated summary value exceed the default precision of interval : INTERVAL DAY(2) TO SECOND(6)
i get an error :
ORA-01873 the leading precision of the interval is too small
Cause: The leading precision of the interval is too small to store the specified
interval .
Action: Increase the leading precision of the interval or specify an interval with
a smaller leading precision
although i can determine the precision of interval the declaration of the new type to maximum like :
+...........+
CREATE OR REPLACE TYPE "DAY_TO_SECOND_SUM_TYPE" as object
+(TOTAL INTERVAL day(9) to SECOND(6) ...........+
+.......................+
but the problem remain (in fact the error move from one functions of type to another function )
due i can't determine the precision of data type when i define function in PL/SQL it is illegal*
HOW CAN I SOLVE THIS PROBLEM AND BE ABLE TO SUMMARY INTERVAL DATA TYPE WHAT EVER THE RESULT OF SUMMARY IS HUGE

Instead of 'interval day to second' in method declaration use internal datatype 'DSINTERVAL_UNCONSTRAINED'.
There are more unconstrained types in oracle.

Inconsistent datatypes: expected INTERVAL DAY TO SECOND got DATE
Hi All,
I am developing a Java application in which I construct a query and pass some values to get the results from the Oracle db.
The code block is:
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(30000);
Date threshold = new Date(calendar.getTimeInMillis());
And when the threshold value is passed, I am getting the following error:
ORA-00932: inconsistent datatypes: expected INTERVAL DAY TO SECOND got DATE
How to convert the threshold value into INTERVAL DAY TO SECOND in java?
Thanks in advance.
Regards,
Bh.So presumably LASTUPDATE is a timestamp column and you pass THRESHOLD as a date, and get something like this:
WITH work_reservations AS
( SELECT TIMESTAMP '2007-07-10 01:23:45' AS lastupdate FROM dual )
SELECT *
FROM work_reservations
WHERE (sysdate - lastupdate) > DATE '2007-01-01';
ERROR at line 5:
ORA-00932: inconsistent datatypes: expected INTERVAL DAY TO SECOND got DATEWhy not just compare lastupdate with threshold? Subtracting a date or timestamp from a timestamp gives an interval.
It might also be marginally more efficient to compare a timestamp with another timestamp, rather than mixing dates and timestamps and incurring an implicit conversion. -
How to import from CSV file into INTERVAL DAY TO SECOND column?
Hello,
I need to import data from a csv file that has a column that stores time-intervals (e.g. 2:06:02 Hours:Minutes:Seconds) into a table column INTERVAL DAY TO SECOND.
Does any of you know what format I should apply?
I tried HH:MI:SS but it didn't work.
Any suggestion is welcomed (including changing the column type to something else that might hold time-intervals in it....).
Thanks,
AndreiAndrei,
There is no native support for the INTERVAL datatype in the Text loading facilities of Application Express.
To work around this known limitation, I suggest either creating a temporary table or a shadow column in your existing table. You could then upload your data for the interval as a VARCHAR2 and then use SQL to convert to an appropriate interval value.
For example:
1) Create a table with:
create table foo (id number primary key, i interval day to second, shadowi varchar2(4000) )2) Using your sample data set, load this data into table FOO, loading the second column of this data into column SHADOWI
1 01:06:02
2 02:06:02
3 03:01:013) Issue the following SQL to convert the value in your shadow interval column to your actual interval column
update foo set i = to_dsinterval( '0 ' || shadowi )Note that you'll need to prepend the '0' to formulate a valid interval literal value.

Oracle Forms New Features - Your input. Supporting data types
I am interested to know IF we were to support any new database types in Oracle Forms 11g, which types would you like supported and why. I'd also like to know if you are currently working around the absence of a database type.
Please note, this is not any kind of commitment to support new data types in Oracle Forms applications but we are interested to know if there is demand and if so, for what types.
Thanks
Grant Ronald
Oracle Forms Product Management
p.s lets keep the thread focused on the topic so please don't post technical questions or comments about different new features - if you want to, start a new thread - thanksHi Grant,
support for the "new" - well they exists since 9iR1 ... 2001 - data types TIMESTAMP, TIMESTAMP WITH TIME ZONE, TIMESTAMP WITH LOCAL TIME ZONE, INTERVAL YEAR TO MONTH and INTERVAL DAY TO SECOND would be very helpful.
Currently it's not possible to use the Data Block Wizard to create a data block for table/view that contains one of these columns.
(In Forms Builder 10.1.2.3 it fails with a strange error message ... iewbdbc_oracle_to_id ... C:\forms\101220\src\ie\iewbdb.c:724 ...)
So, one has to create the data block and the items manually. The items have to be CHARS.
Then forms is able to fetch and display these columns. The user can edit them as normal.
A WHEN-VALIDATE-ITEM trigger can be used to make sure that the implicit conversion from CHAR to the "new" datatype works.
For example, an INTERVAL YEAR TO MONTH column (b):
declare
l_invalid_interval exception;
pragma exception_init(l_invalid_interval, -1867);
l_invalid_month exception;
pragma exception_init(l_invalid_month, -1843);
l_dummy interval year(9) to month;
begin
l_dummy := to_yminterval(:block2.b);
exception
when l_invalid_interval
then
message('invalid interval');
raise form_trigger_failure;
when l_invalid_month
then
message('invalid month');
raise form_trigger_failure;
when others
then
message(error_text);
raise form_trigger_failure;
end;This nasty trick works for most of the "new" datatypes except with TIMESTAMP WITH TIME ZONE.
In Forms 10.1.2.3 the following WHEN-VALIDATE-ITEM trigger can (incorrectly!) fail:
declare
l_dummy timestamp with time zone;
begin
l_dummy := to_timestamp_tz(:block2.a);
end;It fails with "ORA-01804: failure to initialize timezone information", if the time zone is not like "-11:00", but like "EUROPE/PARIS". Don't know why...
If we recode our trigger to make a round-trip to the database, it works:
declare
l_dummy timestamp with time zone;
begin
select to_timestamp_tz(:block2.a)
into l_dummy
from dual;
end;We could avoid these tricks, if Forms (and Reports) would support these type natively.
Thanks, Michael
PS: The TIMESTAMP and INTERVAL data types should of course be supported as items, parameters, globals and record groups columns.

Problem loading PostgreSQL Bytea data type to Oracle Raw data type
We are migrating our database from PostgreSQL to Oracle. First, we convert the BYTEA data type in PostgreSQL to Oracle RAW. The BYTEA data type is variable bytes array. How can we load the BYTEA data type to Oracle RAW data type? Or I have to convert to different data type. thanks.
Peter,hi,
Instead of 'interval day to second' in method declaration use internal datatype 'DSINTERVAL_UNCONSTRAINED'.

I see the Data-types such as VARCHAR in the ALL_OBJECTS view with an OBJECT_TYPE of 'TYPE'. Since these are listed along with other 'TYPE' objects, how to identify the Data-types alone?
Or, are the Data-types stored in some other table? Because, when I query ALL_OBJECTS at home I see the data-types but don't see them at work. Is there an ALL_XXX view where I can retrieve all the data-types?
Thanks in advance...

Initializing INTERVAL data type
I have a situation in which I want to keep track of the amount of time it takes to perform a task that it comprised of a number of steps. I need to get the amount of time to perform each task by subtracting the stop and start times; then these need to be added to a running total to track the total time to perform the task. My PL/SQL code looks something like this:DECLARE
start TIMESTAMP;
stop TIMESTAMP;
task_time INTERVAL DAY TO SECOND;
total_time INTERVAL DAY TO SECOND;
BEGIN
total_time := <an initial value (0)>; -- How is this done?
FOR i IN 1 .. <some upper limit> LOOP
start := <some date and time>;
stop := <some other date and time later than start>;
task_time := stop - start; -- Subtracting TIMESTAMPs results in an INTERVAL data type
total_time := total_time + task_time; -- Adding two INTERVALS results in an INTERVAL data type
END LOOP;
END;My question, as noted in the code is how do you initialize an INTERVAL data type?
I have tried "total_time := 0" but I get a compile error because the types are not compatible. I have also tried setting it to "TO_DATE('00:00','hh24:mi')" but this also results in a type compatibility issue.
Should I be approaching the problem in another way completely?Nothing could be simpler:
declare
v_interval interval day to second;
begin
v_interval := interval '0' hour;
dbms_output.put_line(v_interval);
end; -

ORACLE9I - INTERVAL DATA TYPE
=============================
PURPOSE
Oracle9i 부터 추가된 INTERVAL data type에 대해 알아보자.
Explanation
INTERVAL data type은 datetime 기간을 저장하는 type이다.
아래의 syntax를 확인해 보자.
INTERVAL <interval qualifier>
Examples:
INTERVAL YEAR TO MONTH
INTERVAL DAY (6) TO SECOND (5)
INTERVAL type에는 다음의 두 가지 종류가 있다.
1. Year-month interval (INTERVAL YEAR TO MONTH)
연과 월의 기간을 저장하는 type으로 각각 연수,월수를 나타낸다.
Keyword Meaning
YEAR Years
MONTH Months
2. Day-time interval (INTERVAL DAY TO SECOND)
각 DAY, HOUR, MINUTE, and SECOND 를 저장하는 type으로 일반적으로
사용하는 date format으로 저장한다.
Keyword Meaning
DAY Days
HOUR Hours
MINUTE Minutes
SECOND Seconds and possibly fractions of a second
이 type은 생성할 때 각 day와 second의 자리수를 지정해야 한다.
default 로는 day(2), second (6) 으로 지정된다.
Year-month interval type은 다른 type과 함께 비교할 때 다른 data의 각 year, month
와 비교되며, day-time interval의 경우에도 다른 type의 day-time 값과만 비교된다.
3. INTERVAL item의 valid value.
Keyword Valid values
YEAR Unconstrained except by <interval leading field precision>
MONTH 0..11
DAY Unconstrained except by <interval leading field precision>
HOUR 0..23
MINUTE 0..59
SECOND 0..59.9(N) where "9(N)" indicates the number of digits
specified by <interval fractional seconds
precision> in the <interval qualifier>
4. Interval data type의 sample value.
Data type Literal Example
INTERVAL YEAR TO MONTH INTERVAL '01-02' YEAR TO MONTH
INTERVAL DAY(3) TO SECOND(2) INTERVAL '100 10:20:42.22' DAY(3) TO SECOND(2)
Examples
1. sample table생성후 data입력
create table demo_interval ( a INTERVAL YEAR(2) TO MONTH,
b INTERVAL DAY(2) TO SECOND(6));
insert into demo_interval values(INTERVAL'12-01' YEAR TO MONTH,
INTERVAL'50 10:20:20.123' DAY(2) TO SECOND(3));
commit;
SQL> select * from demo_interval;
A B
+12-01 +50 10:20:20.123000
2. 다른 date type의 data와 이 interval type의 data를 더하거나 계산하여 나타낼 수 있다.
SQL> select sysdate, sysdate+a, sysdate+b from demo_interval;
SYSDATE SYSDATE+A SYSDATE+B
2004-05-12 00:11:46 2016-06-12 00:11:46 2004-07-01 10:32:06
Reference Documents
<Note:149118.1>Nothing could be simpler:
declare
v_interval interval day to second;
begin
v_interval := interval '0' hour;
dbms_output.put_line(v_interval);
end; -
Data Type Mapping from SQL server to Oracle
I am using Oracle 12c with heterogenous services connecting to SQL server DB. Some of the columns in the SQL server SB are defined as 'nvarchar(max)'. These are coming over to Oracle as 'long' type columns. I would like these to be 'varchar2' types in Oracle so I do not have any of the restrictions related to 'long' type fields when using. I can create a view in SQlServer to convert the data type ie. nvarchar(100). What is the highest value I can use to make the data show in Oracle as varchar? BTW I tried nvarchar(4000) but that still showed as long. I tried nvarchar(1000), and that did show as varchar.
The maximum value for a nvarchar2 in Oracle is 2000. The mapping -if the remote column is mapped to an Oracle varchar/nvarchar- depends on the data type returned by the ODBC driver. When the driver returns SQL_Varchar, then the maximum precision is 4000 and when it will map it to SQL_WVarchar then it is 2000.
As your Oracle database uses AL32UTF8 as character set you will get the nvarchar(max) mapped to Oracle longs as the content of your SQL Server nvarchar is stored using UCS2 character set which is covered by the Oracle database charset UTF8. So it shouldn't really matter if the returned string is mapped to an Oracle varchar or nvarchar. -
Domain for data type in Oracle 8i database
Hi Sir,
Does Oracle database supports domain creation for data type.
for example, can I create a domain called shorttext which is VARCHAR2(50). Then when I specify a data type for a column in table, then I just declare the column as domain.
eg. address SHORTTEXT;
--where SHORTTEXT is a domain.
How is this implemented in Oracle database and supported by front end tools like Oracle Developer 6.0.
Hope someone can provide some clear explanation on this.
Thanks.The ordimagesignature is not something you can see or hear. It is strictly binary metadata about the image, used only to compare images to each other.
What are you trying to do?

ORACLE Data Types within Datasets
Hi,
While creating a typed dataset by draging an ORACLE table
from the Server explorer
All Oracle number Columns are using the data type Decimal
inside the dataset.
Is it better to use (change to) the real data type like Int32 etc ?
Have anybody experience ?
Kind Regards
MartinMartin,
OleDb.NET defaults to System.Decimal for Oracle NUMBER columns. The only was is to manually change it after the typed dataset is generated.
If you are working with an untyped dataset ODP.NET will set the DataColumn depending on the precision and scale of the Oracle NUMBER column.

hi,
how to display oralce's data type from system table is there any system table to fetch the data types for that version i'm using Oracle 11g.
in sql server we fetch the details by using
select * from sys.types
this will return what the data types supported by that version
Thanks!There is a package called STANDARD in the SYS schema that defines many of the standard datatypes and functions.
e.g.
CREATE OR REPLACE package SYS.STANDARD AUTHID CURRENT_USER is -- careful on this line; SED edit occurs!

Hello,
I've posted a project at some commercial sites to find someone to help me doing it, but couldn't find any. I thought that it might be impossible doing this type of projects. The following is what was posted expecting someone could help/lead me doing it myself or at least providing any valuable hints, Thank you in advance.
Looking for an Oracle expert to do the software part of a project.
A data to be populated in Oracle database, but unfortunately Oracle doesn't support the required data type to hold it.
An expert has to create custom data type with all required procedures/functions to manipulate the data(Read/Update/Insert/Delete), and provide a method to incorporate the solution in Oracle developer suite to model it.(To use it inside designer tools)
The solution should allow someone to Create a column in a table to hold (for example) three bits in every row(record), mostly used in the project is three bits, but need the solution to be open and customizable to any number from one up to 21. Viewing/entering the data in a record could be as binary string. Saving in a table physically should be in sampling way to save space.
The functions/procedures for manipulating the data should be based on record level and block level(several records of one column with start/end points). For record manipulations a binary string should be used, and for block manipulations a sampled structure should be used.
Thank you for your time.
Platforms:
Oracle Database 9i and above.
Oracle Developer Suite 9i and above.
*/not sure what exactly do you mean by custom data type in SQL? if you mean if there is a user defined data type in oracle thru PL/SQL yes there is. by using the %Type you need not to declare the variable data type explicitly. all you need to do is associate the variable to the column name of the table and use the %Type. see this example below.
SQL> declare
2 vEmpno emp.empno%Type;
3 begin
4 select empno
5 into vEmpno
6 from emp
7 where ename = 'FORD';
8 dbms_output.put_line('employee no: '||vEmpno);
9 end;
10 /
employee no: 7902
