TIMESTAMP datatype in Oracle 8i.

'TIMESTAMP' datatype is not to be available in Oracle 8i.
Is there an equivalent datatype in Oracle 8i as 'TIMESTAMP' in 9i?
Regards,
Bhagat

Timestamp was a new globalization feature in 9i. The only way to handle time in 8i is with the regular DATE type and traditional date arithmetics.

ORACLE TIMESTAMP DataType support in Toplink ?

Currently we have an application that need to create timestamps with precision up to thousands of a second.
Do you know of any other customer that have similar requirements and how they solve this problem ?
We try changing the SQL DDL to change datatype from DATE to TIMESTAMP(3) which can support a timestamp of 1/1000 seconds precision.
We find that if our Oracle column is defined as Oracle DATE, the last 3 digit will be drop and cause us some duplicate key exception for records that
Get inserted within 1 second because the timestamp is part of the primary key.
ts '2004-03-12 17:13:27.792'
So we change the ORACLE column from DATE to TIMESTAMP(3)
What we find is that Toplink produce this exception
Exception [TOPLINK-3001] (OracleAS TopLink - 10g (9.0.4) (Build 031126)): oracle.toplink.exceptions.ConversionException
Exception Description: The object [oracle.sql.TIMESTAMP@321b5e39], of class [class oracle.sql.TIMESTAMP], could not be converted to [class java.util.Date].

Than we try to change our java code and modify the java instance variable type from java.util.Date to java.sql.Timestamp
And we get the following error

========================================================================================================
The TIMESTAMP Datatype
The new TIMESTAMP datatype is almost identical to DATE and differs in only one way:
TIMESTAMPs can represent fractional seconds.
The granularity of a TIMESTAMP value can be as little as a billionth of a second, whereas
DATE variables can only resolve time to the second.
When you declare a TIMESTAMP variable, you can optionally specify the precision that you wish to use for fractional seconds. The default precision is to the millisecond (six decimal digits); the maximum precision is to the billionth of a second (nine decimal digits).

Subject: Problem identified : AddressDetail duplicate key problem
If we look at the exact of the insert statement.
We see that the last address detail insert have key of
Address ID = '5a052407-dac6-42ad-bbbf-29edc94488c1', and
TransactionStartDate = {ts '2004-03-12 17:13:27.792'},
While in the database, we look like we have an entry of
Address ID = '5a052407-dac6-42ad-bbbf-29edc94488c1', and
TransactionStartDate = {ts '2004-03-12 17:13:27.229'},
If my memory served me right, while
{ts '2004-03-12 17:13:27.792'}, is different than {ts '2004-03-12 17:13:27.229'},
because are Java timestamps that have precison up to MicroSeconds, therefore 229 is different than 792.
However, when this timestamp is saved to Oracle, I believe (have to check with Mei) that oracle only takes
Up to '2004-03-12 17:13:27 and discard the 229 or 792 because that is the maximum precision of timestamp for oracle.
So we have the second insert have the same '2004-03-12 17:13:27 after stripping off the 792 and we have a same record with the same same '2004-03-12 17:13:27 in the database and
Therefore causing duplicate key exception.
That is why this is happen only once in a while when 2 rapid fire inserts happen in less than 1 second of each other.
The solution actually is in the ESS code itselfs.
The current ESS code will send addDependentToClient multiple times, one for each dependent added
On the screen.
The right way is to add all the dependent on the screen all at once.
To have course grain method like addDependentsToClient, and have a collection or array of dependents as input parameter.
This way we are not causing the participant to create history of themselves multiple times within a very short period of time. It save disk space, conform to a single UOW per submit and that is what I proposed
To solve this problem from the root cause is by enhancing the method to save multiple dependents in one shot rather than a loop of multiple calls.

We are back-porting the support for oracle.sql.TIMESTAMP to 9.0.4 in an upcoming patch-set. It is possible to enhance TopLink using a customer conversion manager or database platform to add this support if required in the short term.

Timestamp datatype not output correctly in table export

When using the data export from table view timestamp datatype is not handled correctly. It shows as oracle.sql.TIMESTAMP@14c0761.
Works fine from SQL Explorer view though.

Im using the same build. 1.0.0.15.27.
You can try any export option. I tried SQL Insert.
If you right click from the data grid (SQL Worksheet or Table view it works fine)
In the table view, if you go to Actions -> Export -> SQL Insert then it doesn't.

Equivalent datatype in Oracle for datetime of SQL Server

Hello Everyone,
I'm very much new to Oracle. I have been working with SQL Server since 3yrs. Currently I'm working with Oracle 11g.

Oracle date format can be anything you want, either by default at the session level or preferably explicitly using to_char and a format mask.
Format masks are documented here.

Sybase datetime col...how to generate as timestamp col in oracle ddl

i'm having trouble understanding the date mapping...
i'm taking the defaults (per http://dermotoneill.blogspot.com/2008/06/offline-data-move-dates.html)...
but my sybase datetime columns are being generated as date columns in the oracle ddl. (so i lose the milliseconds)
is there a way to tell the tool to generate datetime cols as timestamp in the oracle ddl?
thanks!

If you want to keep the milliseconds you have to make sure you don't map it to datatype date. You need to change the default mapping to TIMESTAMP:
Open SQLDev Migration Workbench
- click on the capture model
- right mouse click on the captured Sybase database
=> set data mapping
Make sure you change the deafult of DATETIME to TIMESTAMP(6).
Then recreate the Oracle model and you'll see the data type is now timestamp which includes the milliseconds.

Timestamp datatype issue in Expression

Hi
I am extracting data from oracle table which timestamp datatype for one column then connected to Expression operator. When i see the data type of timestamp in sourcetable it is timestamp(3), But when i see the data type of timestamp in Expression operator it says timestamp(3) but it is adding 6 in the precision by default and that cannot be changed. I tried creating new column in expression it behaved the same. there by my mapping is giving me the warnings regarding this.
Could you guys please help on this.
Thanks

Hi Cezar,
Thanks for your quick reply.
I am currently doing the second step you have mentioned. I even went to the extent of cutomizing the I$ tables getting created with a custom structure to avoid this. But this is very tedious as i have hundreds of columns in the table.
Is this a bug in ODI? I am asking this because this is a general functionality and should be ideally covered by such a good ELT tool.
I have raised a SR for the same, let us see what solution they have in store:)
Anyway thanks for your valuable suggestion its really useful.
But I have a doubt regarding the versions. Whats the difference between versions 10.1.3.2.0 which I am using and 10.1.3.4.0? I hope this version is not creating this issue?
Thanks,
Vikram

How to handle national character set datatypes in oracle?

Hi
Can anyone tell me how to handle national character set datatypes in oracle?
Thanks in advance

And for data manipulation, append "N" the literal values being used in the command.
The "N" indicates that the string is to be treated as Unicode Text.
For Example: insert into TableName (ColumnName) values (N'ValueToBeInserted');

Converting ntext datatype of MS SQL to LOB datatype of Oracle using ODI

Hi
Could anyone help me how I can convert ntext datatype of MS SQL to BLOB/CLOB datatype of ORACLE using ODI tool? I have tried and it seems that ODI couldn't able to create working table with datatype of LOB.
Thank you in advance.
Myat

Try using the Incremental Update (PL/SQL) IKM. I believe this will only handle 1 CLOB column in any interface - also pay attention to the KM notes for additional constraints and requirements.
Make your staging area the same as the target.
Use the TO_CLOB function to convert the data for your field, and execute this on the target.

Timestamp field in Oracle

I have an application to log some data into my Oracle via ODBC. There's a field called 'timestamp' which is generated automatically by my logging application.
In Oracle, if I do a 'SELECT', it reads 07-MAY-04, but if I import all the data to Access, it reads like this: 5/7/2004 3:08:00 PM.
I want to be able to select a range data based on time. For example, I want to select everything that is within 5/7/2004 1:00:00 PM to 5/7/2004 4:00:00 PM, how do I write my SQL query?

I assume, first of all, that the column named "timestamp" is of type DATE, not of type TIMESTAMP.
In Oracle, a date always contains a date and a time component. The default date format, however, omits the time part of the date when it comes time to display it. You can alter that behavior by using an explicit to_char cast or by altering your NLS_DATE_FORMAT
SELECT to_char( timestamp, 'DD-MON-YYYY HH24:MI:SS' )
FROM <<your table>>or
ALTER SESSION SET NLS_DATE_FORMAT = 'DD-MON-YYYY HH24:MI:SS';
SELECT timestamp
FROM <<your table>>When you want to SELECT data, you will want to use the to_date cast to convert a string to a date for comparison, i.e.
SELECT *
FROM <<your table>>
WHERE timestamp BETWEEN to_date( '5/7/2004 13', 'MM/DD/YYYY HH24' )
AND to_date( '5/7/2004 16', 'MM/DD/YYYY HH24' );Justin

Capturing EDT/EST timezone with TIMESTAMP datatype

Hi guys,
In 9i DB, I need to capture date and timestamp with EDT or EST time zone specifiers. For testing pursposes, I wrote the following code and the result is as:
SET SERVEROUT ON
DECLARE
v_date TIMESTAMP WITH LOCAL TIME ZONE;
BEGIN
v_date := TIMESTAMP '2003-06-15 12:16:30 US/Eastern EDT';
DBMS_OUTPUT.PUT_LINE(v_date);
END;
I get the following result:
15-JUN-03 12.16.30.000000 PM
Actually I need 15-JUN-03 12.16.30.000000 PM EDT or EST depending on the daylight times in the Eastern coast. Also, I did change my SESSION with ALTER SESSION SET TIME_ZONE='US/Eastern' but still I do not get the promising output. I just put it to the forum in the hope if someone could help me out with the new timestamp datatype in this case please.
Any help will highly be appreciated.
Thanks

Mapping datatype in oracle goldengate

Hi
Is it possible to map datatype in oracle goldengate? Suppose we have same table name on both source & target database but column widths are different.

Hi again,
It might be possible to code a mapping post processor that transforms eg. a column definition: my_column_clob varchar2(4000) => my_column clob
but I have no clue on how the runtime platform would react to this, eg. when reporting detailed errors. Implementing on your own means that you will lose some standard OWB functionality also - eg. upgrade/import table.
