Sql srver datetime to oracle by sql developer

Using the tool Sql Developer 3.1.07, try to migration an sql server 2008 database to oracle 11gR2. The tool failed at a few places. One point:
sql server table:
create table Table1 (
[modificationDatetime] [datetime] NOT NULL,
The tool generated Oracle script for the same table:
create table Table1 (
modificationDatetime DATE DEFAULT SYS_EXTRACT_UTC NOT NULL,
The script actually does not work in oracle with the error:
SQL Error: ORA-00984: column not allowed here
00984. 00000 - "column not allowed here"
Simplely replacing 'SYS_EXTRACT_UTC' with 'sysdate' works.
Wondering if this is a bug of the tool.
Thanks,
Fan

The SQL Server table I used to reprot the issue at our SQl Dev team is:
drop table DateTimeMig;
create table DateTimeMig ([modificationDatetime] [datetime] NOT NULL default getutcdate());
And I reproduced with 3.1 the migration code issue:
-- DROP TABLE DateTimeMig CASCADE CONSTRAINTS;
PROMPT Creating Table DateTimeMig ...
CREATE TABLE DateTimeMig (
modificationDatetime DATE DEFAULT SYS_EXTRACT_UTC NOT NULL
Issue is investigated by migration developer team.

ORA-01841 Converting SQL Server DateTime to Oracle Date

I have Oracle 11gR2 x64 running on my Win7 Enterprise x64 personal system. I'm trying to convert the TSQL to create a database in SQL Server 2008 Express for my C# class to Oracle, and I've run into a "interesting" problem loading date data.
The SQL Server 2008 TSQL InvoiceDate column in the Invoices table has datatype DATETIME:
*[InvoiceDate] [datetime] NOT NULL,*
which Oracle does not support. The Oracle InvoiceDate column in the MMAB_Invoices table has datatype DATE:
InvoiceDate DATE NOT NULL,
The fun begins with the TSQL INSERT statements (for example):
INSERT [dbo].[Invoices] ([InvoiceID], [CustomerID], [InvoiceDate], [ProductTotal], [SalesTax], [Shipping], [InvoiceTotal]) VALUES (18, 20, CAST(0x00009CFD00000000 AS DateTime), 151.0000, 11.3300, 6.2500, 168.5800)
As you can see, whoever wrote the load script thought it would be totally awesome to convert hex (binary?) data to generate a date, instead of using data readable by a human being.
BTW, the date generated is 2010-01-13 00:00:00.000.
After Reading The Fabulous Manual and searching the OTN Discussion Fora, what I came up with is
INSERT INTO MMAB_Invoices (CustomerID, InvoiceDate, ProductTotal, SalesTax, Shipping, InvoiceTotal) VALUES (20, TO_DATE(UTL_RAW.CAST_TO_VARCHAR2(HEXTORAW('00009CFD00000000')), 'YYYY-MM-DD HH:MI:SS'), 151.0000, 11.3300, 6.2500, 168.5800);
which returned
Error starting at line 846 in command:
INSERT INTO MMAB_Invoices (CustomerID, InvoiceDate, ProductTotal, SalesTax, Shipping, InvoiceTotal) VALUES (20, TO_DATE(UTL_RAW.CAST_TO_VARCHAR2(HEXTORAW('00009CFD00000000')), 'YYYY-MM-DD HH:MI:SS'), 151.0000, 11.3300, 6.2500, 168.5800)
Error report:
SQL Error: ORA-01841: (full) year must be between -4713 and +9999, and not be 0
*01841. 00000 - "(full) year must be between -4713 and +9999, and not be 0"*
**Cause: Illegal year entered*
**Action: Input year in the specified range*
The PK InvoiceID is automatically generated by a BEFORE INSERT trigger that uses a sequence.
Suggestions?
Thanks.
P.S. Happy New Year!!!

Your hex conversion is certainly not returning a date format:
sql> select UTL_RAW.CAST_TO_VARCHAR2(HEXTORAW('00009CFD00000000')) from dual;
UTL_RAW.CAST_TO_VARCHAR2(HEXTORAW('00009CFD00000000'))
┐²To convert the hex number to decimal, simply use to_number:
sql> select to_number('00009CFD00000000', 'xxxxxxxxxxxxxxxx') from dual;
TO_NUMBER('00009CFD00000000','XXXXXXXXXXXXXXXX')
1.7261E+14Now, before you can make any further calculations with that number, you need to know how it represents the date of 2010-01-13. Luckily, we've got Google nowadays. ;-)
Sql server representation seems to be an 8 byte field. The first 4 bytes stores the number of days since SQL Server's epoch (1st Jan 1900). The second 4 bytes stores the number of milliseconds after midnight.
sql> select to_number('00009CFD', 'xxxxxxxxxxxxxxxx') from dual;
TO_NUMBER('00009CFD','XXXXXXXXXXXXXXXX')
40189
sql> select to_date('1900-01-01','yyyy-mm-dd') + 40189 from dual;
TO_DATE('
13-JAN-10So, the conversion would be something like this:
sql> select to_date('1900-01-01','yyyy-mm-dd') + to_number(substr('00009CFD00000000',1,8), 'xxxxxxxx') + to_number(substr('00009CFD00000000',9,8), 'xxxxxxxx') / (24*60*60*1000) from dual;
TO_DATE('
13-JAN-10Note: Oracle DATE format specifies a datetime up to the second, whereas the sqlserver DATETIME format specifies a datetime up to the millisecond; if that precision is needed, use Oracle's TIMESTAMP instead.
Note: using an internal representation is risky, implementation details may change. In this case, it seems pretty unlikely that Microsoft will ever change the datetime internal representation, since that would break lots and lots of code.

Hi,
You could use the 'Translation Scratch Editor' in SQL*Developer to translate SQL*Server statements to Oracle.
SQL*Developer is free and can be downloaded from here -
http://www.oracle.com/technetwork/developer-tools/sql-developer/overview/index.html
Once installed start it up, then go to 'Tools' - 'Migration' - 'Translation Scratch Editor'
I did run the statement you have posted here through it but it gave errors so looks like there may be a problem with the syntx in any case.
Does this query run as it is in SQL*Server ?
Regards,
Mike

Migrating data from oracle to sql server

I have two databases(Oracle and Sql Server) in my company.
I want to migrate some data on daily basis from Oracle to Sql Server.
what are the best methodologies used to perform this task?
Can we schedule this task on daily basis?
please help me guys

Salma,
First and foremost, you need to understand that there are architectural difference between Oracle and SQL Server (with the major one being the difference between Oracle's PL/SQL and Microsoft's Transact-SQL) thus, it will not be an easy task to migrate data from Oracle Database to SQL Server. As far as the use of tools is concerned, you can utilize the following tools (third party tools not recommended) to achieve this:
Microsoft SQL Server Migration Assistant (Oracle to SQL)
http://www.microsoft.com/sqlserver/2005/en/us/migration-oracle.aspx
Oracle SQL Developer Migration Workbench (SQL to Oracle)
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
But before proceeding with anything, I would recommend you to read through the following post as it lists down the primary compatibility resources and migration guidelines:
Migrating from Oracle to SQL Server

Hope this helps.

Oracle PL/SQL Developer Certified Associate

I am planning to take the exam for "Oracle PL/SQL Developer Certified Associate".
There are 2 exams under this certification. The first exam can be taken from any of these 4- 1Z0-007 or 1Z0-007 or 1Z0-047 or 1Z0-051. The second exam is 1Z0-147. But does any of these 2 exams need a mandatory online/inclass course offered from Oracle?
I appreciate if anyone who has taken this exam could help me and explain this.
Thanks in advance.

Oracle Database 11g Administrator or Oracle PL/SQL and Forms Developer?

Hi,
I am thinking about doing an Oracle certification course- Oracle Database 11g Administrator or Oracle PL/SQL and Forms Developer.
Oracle Database 11g OCP and OCM certification requires 3 mandatory training courses to be completed that costs between $1900 and $3250/each. Oracle PL/SQL certication doesn't require any mandatory training course.
Which one of these would be a good choice? Please advise.
Thank you,
Tracy

Regardless of which path you want to take, in order to get the OCP certification in either the DBA or PL/SQL developer track, you must first obtain the respective OCA certification for that track. I'm assuming that since you are still undecided in which path to take that you haven't started working on either yet. If you look at the pages for the OCA DBA and OCA PL/SQL Developer certs and what is required for each, you'll see that the first block of tests for either certification (the SQL based exams) has the same options (1Z0-007, 1Z0-047, 1Z0-051) and passing one of those SQL based exams gives credit towards obtaining both OCA certifications. That might be a good place to start.
Doing one of these tests first might give you some extra time to decide which track you want to pursue. But as Justin said, it really depends on what you do (or plan on doing) in your career as to which path might be more beneficial for you.
As for the OCM level stuff, I wouldn't even think about it until you get the OCP. One step at a time... Same with OCP before OCA. That being said, my suggestions are just that, suggestions. You're free to take any exams/courses in any order, but you won't be able to obtain the certs until you have completed the requirements for each.

Query Regarding the Oracle PL/SQL Developer OCA

Hi All
I am planning to go for the certification "Oracle PL/SQL Developer OCA "
But I am not sure what is value of this certification in market.
Please help me out.
Thanks in advance
Amit

My view is this: The more you can put on your resume, usually the better. By itself, its not worth anything. Combined with several years of experience, it could make a difference. If you go for a job and have 5 years of experience and a certification, and the other candidate just has 5 years, as long as you both interview well, I'd say you have a slightly better shot because you have that extra thing on your resume.
You need to look at it in that respect - but its not a magic key to get you any job. Of course different countries may be different in how they view certiciations.

Developing database views between Oracle and SQL Server tables

I am on Oracle 10.2, my organization has many SQL Server databases as well and has now made
SQL server as company standard so many new databases will be developed in SQL Server. It is of course
not possible to convert all Oracle databases to SQL Server, so a mix environment will exist. Two questions:
1. Is it possible to develop database views in Oracle (10g in my case) which join Oracle tables with tables in SQL Server 2008? If yes, how. I have seen some heterogeneous connectivity setup to connect SQL Server to Oracle, but not sure whether it is possible to develop a database view across two databases.
2. I know it is not a SQL Server forum, but many DBA’s know both Oracle and SQL Server. Is it possible to develop views in SQL Server (SQL Server 2008 R2 in my case) which join Oracle 10g and SQL Server 2008 tables? I know in SQL Server, there is way to set up linked servers, but do not know whether it is possible to develop views.
Thanks a lot for your insight.

You can create views that join local Oracle tables and remote SQL Server tables. I'm pretty sure you can do the reverse as well but I haven't personally done it.
However, I would be very concerned about the performance you'd get if you created that sort of view. You'd very frequently end up in a situation where Oracle has to pull all the data in the remote table across the database link in order to apply predicates and join the data locally. That could be disastrous from a performance standpoint.

How to buy vouchers for Oracle PL/SQL Developer Certified Associate ?

I want to become Oracle PL/SQL Developer Certified Associate.
For this, I want to write 1Z0-007 (Introduction to Oracle9i SQL) and
1Z0-147 (Program with PL/SQL) tests.
I went through so many posts in the forum, but I didn't get the required answers.
Kindly reply my queries:
1) Will clearing the above two tests will make me Oracle PL/SQL Developer Certified Associate?
2) Should I purchase two separate vouchers for those two tests?
3) Should I give both the tests one by one at the same time or can I give them on different days?
Please answer my questions. Or atleast guide me where can I get the answers?

1) Will clearing the above two tests will make me Oracle PL/SQL Developer Certified Associate?These exams fulfill the requirements of the certification which should be awarded if you pass the exam. Even if you pass the exams you are not certified until you received confirmation from Oracle via a success kit or Certview that you are certified
2) Should I purchase two separate vouchers for those two tests?In my opinion there is usually little advantage in buying vouchers; but you may have different situation with your particular situation. Vouchers also may go wrong on people from time to time. Probably the excpetion for vouchers being good is when discounted vouchers are offered as part of training.
See: http://www.pearsonvue.com/oracle
3) Should I give both the tests one by one at the same time or can I give them on different days?Best practice for ordinary mortals is probably to take exams on different days. However as you are choosing 1z0-007 and 1z0-147 and not the more modern choices of 1z0-051 and 1z0-144 I shall leave that to yourself

Same SQLs different in two versions of Oracle 12c RDF Developer's Guide

There are two versions of Oracle 12c RDF Developer's Guide, one has the SQL insert as
INSERT INTO articles_rdf_data VALUES (2,
SDO_RDF_TRIPLE_S ('articles','http://nature.example.com/Article1',
'http://purl.org/dc/elements/1.1/creator',
'Jane Smith'));
the other one has the change highlighted:
INSERT INTO articles_rdf_data VALUES (2,
SDO_RDF_TRIPLE_S ('articles','<http://nature.example.com/Article1>',
'<http://purl.org/dc/elements/1.1/creator>',
'"Jane Smith"'));
Which one is correct?
Thanks.

The second one is correct. It is from the latest version of the user guide.

Migrating SQL Server DB to Oracle DB - probably EASY answer

I completed the tutorial on migrating SQL Server DB to Oracle. When I try on my own database, it all migrated well except anything containing a datetime. When I run the oracle_ctl.bat file and view any of the log files, I see Record 1: Rejected - Error on table DBO_RIVERSIDEDB_NCWCD_TEST.TS6HOUR_TAIN, column DATE_TIME.
ORA-01843: not a valid month. Do I need to change the first line of the file set NLS_DATE_FORMAT=Mon dd YYYY HH:mi:ssAM ? In the .dat file created from the unload_script.bat, the data starts out 1275<EOFD>2007-05-11 00:00:00.000<EOFD>74.900000000000006<EOFD><EOFD><EORD>1275<EOFD>. So my questions is about the date_format - is that the same for all SQL Server databases or do I need to enter something based on MY database? I am definitely a newbie so this is probably a super easy question. Thanks so much for any help!

Hello,
There are two different date format in SQL Server.
1] DateTime : 2010-08-03 12:48:15.170
2] SmallDateTime: 2010-08-03 12:48:00
Both the date will be inserted in Oracle Date column.
Is there any automated way to generate datamove script to tackle these differences? I've around 200 tables to be migrated and there may be many such cases.
The issue with Oracle SQL Developer setting i.e. Tools >Preferences> (Under) Migration> Data Move Option, there are two masks we can specify, one for Date Mask and other for Timestamp. How can I set both of these for converting data into Date, not in timestamp.
Below is my .CTL file, none of below fields are timestamp, but since incoming data in in timestamp format, it is applying timestamp mask and eventually failing to insert data into table
load data
infile '[PARTSORDER].dat'
"str '<EORD>'"
into table admin.PARTSORDER
fields terminated by '<EOFD>'
trailing nullcols
ORDERID ,
GenDate "TO_TIMESTAMP(:GenDate, 'YYYY-MM-DD.HH24.MI.SS.ff3')",

How to UpLoad the Diffent type of files Through Oracle Pl/Sql...?

I want one reusable component to be developed, My requirement is as follows...
We get .CSV,.XML,.DOC.PDF files on the N/w drive. One Batch Job will be running every night and this job should upload all the files present in that N/w drive to the database (Each File should be stored in one row with unique ID) and after loading of each file is done , move the uploaded file to the backup directory.
Note : Average file size is 10-15 MB.
Loading of files in database should be done only using Oracle procedure/function.

Yes it can be done. Simply consult the applicable manuals that contains all of the details on how to do it. The manuals are:
- Oracle® Database Application Developer's Guide - Large Objects (refer to Chapter 6 section on Using PL/SQL (DBMS_LOB Package) to Work with LOBs)
- Oracle® Database PL/SQL Packages and Types Reference (refer to the chapter on DBMS_LOB)

General question on SQL Server 2000 to Oracle 10g

Hello all,
I just have a general question on migration from SQL Server 2000 to Oracle 10g using SQL Developer.
How does it migrate Users with proper privileges from SQL Server to Oracle? Follow the interface steps? Or should the users be created on destination Oracle side?
Thank you.

Hi,
It depends which type of migration you are making.
For a 'Standard' migration when you migrate data a 'create user' statement is created as part of the migration and you will see this in the generated code.
If you are using the 'Quick' migration option then you need to create the Oracle user or use an existing user to receive the data.
Your best option is to review the documentation available from -
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
or directly from -
http://download.oracle.com/docs/cd/E12151_01/index.htm
and then get back with specific questions if this does not give you the information you need.
Review the chapter -
2. Migrating Third-Party Databases
in -
Oracle® Database SQL Developer User’s Guide Release 1.5

Mike
