SQL Server To Oracle Conversion Tools

We are moving from Sql Server to Oracle. Are there some tools, scripts etc that one can use to convert SQL Server Stored Procedures to Oracle Stored Procedures.
Also where would one find a script that would generate Insert, Update, delete and Select stored procedures by just taking thename of a table and then getting the names of all the columns and data types from system tables and then creating the basic stored procedures in the datbase.
Thanks.

Take a look at Oracle Migration Workbench.

can anyone help me

Hi <Please supply name>,
SQL Developer 1.5.1 is very old (> 3 years old). Lots of improvements have been made since then.
You can download SQL Developer 3.1 (EA 1) here
http://www.oracle.com/technetwork/developer-tools/sql-developer/sqldev-ea-download-486950.html
Heres a video of migrating Sybase to Oracle using SQL Developer 3.1
Sybase and SQL Server migrations are identical.

Migrating from SQL Server to ORACLE using SqlDeveloper tool - IN OUT CURSOR

Hi All,
I am new to Oracle. I am asked to migrate a database from SQL Server to ORACLE. I have migrated all the SP's and functions except 2. I am facing the following problem. Pls do reply me if anyone knows the solution since I am struggling for the past 2 days for these two functions
the function is as follows in ORACLE.
create or replace
FUNCTION ABC
AA IN VARCHAR2,
BB IN DATE,
CV_1 IN OUT SYS_REFCURSOR
When I tried to call from some other function its showing me an error.
I called from another function as follows:
ABC(CC,DD,CV_2);
Shall I know how to call the above function? I feel someone has faced the same problem before. Thanks in advance for the help.
Thanks,
Srinivasan.T

Its returing a number only. I am just giving part of the function.
create or replace
FUNCTION ABC
AA IN VARCHAR2,
DD IN DATE,
CV_1 IN OUT SYS_REFCURSOR
RETURN NUMBER
AS
When I call the function which has a IN OUT SYS_REFCURSOR as a parameter I am facing this problem.
I need to know how to call a function which has the IN OUT SYS_REFCURSOR parameter.
Thanks,

Converter program for MS SQL Server to Oracle

My problem with converting MS SQL Server queries in a SQL Pass-thru is becoming critical at my job.
I am hoping there is an easy converter tool that will let a user take SQL Server statements and feed them into a converter that outputs Oracle SQL.
Does such a program conversion tool exist?
I bet not, right?

Your bet is right as SQL-Server's SQL implementation is not the same as Oracle's SQL implementation. There are numerous differences. Translating one to the other is not a 1:1 keyword swap.
And when these SQL statements involve locking and concurrency, there are also significant differences in core database functionality between SQL-Server and Oracle.
What exactly is the problem you are facing? SQL-Passthru is specifically designed as a SQL interface that does not touch and change (and muck up) a SQL being passed to a remote database - so the actual raw SQL text being send is what arrives at the server end. Allowing you to, for example, use Oracle's SQL dialect inside SQL-Server to talk to a remote Oracle database - without SQL-Server throwing errors about Oracle dialect being used. Oracle has a similar passthru option.
Why is this not working? Or is the issue something else?

Related to migration of db from sql server to oracle 11 g

We're trying to migrate a Sql server managment studio database to Oracle 11g using SQL Developer 4.0. We can successfully connect to both Sql server managment studion 8.0 and Oracle 11g using the tool, as well as click through the Migration Wizard and start the migration.
This opens the Database Migration dialog box, which indicates the capture process starts normally. we get the following error:
ora :01440 : can not insert null into migrlog (id column) ,
\and then after some time , i get an error that migration failed
i am not getting the reason,I thing it may be due to reason that , I have table's column in my source db with more than 30 character.
If i am migrating one by one table . then it is not giving any error, and identifier name is getting shrink in 30 character. but i am not getting the view , stored procedure , indexes , and others
then what is the solution for that, somebody pls suggest any help?????????????

Pl do not post duplicates - related to migration of db from sql server to oracle 11 g
Continue the discussion in your original thread
The error message is explicitly clear
ora :01440 : can not insert null into migrlog (id column)
Your process is trying to insert a NULL value into the ID column, which presumably cannot be NULL

NVARCHAR - NVARCHAR2 datatype mapping between sql server and oracle.

Question regarding size allocation that occurs for NVARCHAR columns in sql server to NVARCHAR2 in Oracle in the migration tool.
The migration tool has converted NVARCHAR columns to be twice their size as NVARCH2 in Oracle. Example, a table whose column is mycol NVARCHAR(40) gets migrated as mycol NVARCHAR2(80).
In SQL Server land, the designation of a column as NVARCHAR(40) will physically store the column as 80 bytes. However, as I understand from this excerpt (taken from here: http://www.oracle.com/technology/oramag/oracle/03-nov/o63tech_glob.html), that Oracle in essence will do the same thing for NVARCHAR2:
To make it easy to allocate proper storage for Unicode values, Oracle9i Database introduced character semantics. You can now use a declaration such as VARCHAR2(3 CHAR), and Oracle will set aside the correct number of bytes to accommodate three characters in the underlying character set. In the case of AL32UTF8, Oracle will allocate 12 bytes, because the maximum length of a UTF-8 character encoding is four bytes (3 characters * 4 bytes/character = 12 bytes). On the other hand, if you're using AL16UTF16, in which case your declaration would be NVARCHAR2(3), Oracle allocates just six bytes (3 characters * 2 bytes/character = 6 bytes). One difference worth noting is that for UTF-8, a declaration using character semantics allows enough room for surrogate characters, whereas for UTF-16 that is not the case. A declaration such as NVARCHAR2(3) provides room for three UTF-16 code units, but a single supplementary character may consume two of those code units.
As I read this, NVARCHAR(40) in sql server should be equivalent to NVARCHAR2(40) in Oracle and not NVARCHAR2(80) as it gets translated to - am I missing something? We have a rather large database to migrate so I need to get this size allocation right (and I obviously don't want to truncate any data).
Thanks -

Right - well, that's what I'm suggesting is that NVARCHAR(8) in SQL Server is equivalent to NVARCHAR2(8) in Oracle. Truncation will occur after 8 of any character, including, say, double byte Kanjii characters, which would physically store 16 bytes in the NVARCHAR(8) NVARCHAR2(8) column defn. I tried that in both SQL Server and Oracle, and the behavior is the same.
Also, technically, NVARCHAR2(8) and VARCHAR2(8 CHAR) is roughly the same in terms of behavior, except that in the first case, the physical storage is 16 bytes, while in the second case, it's 24 bytes (to account for 'supplemental' characters or true UTF-8 compliance). Same truncation occurs after 8 of -any- character be it single byte ascii or double byte kanjii, which is the behavior I expect.
Thanks for looking into this. What I decided to do was the following:
What was originally defined in SQL Server as varchar (and translated to VARCHAR2 with the CHAR designation), I removed the CHAR designation since I truly want that number of bytes to be stored, and not characters (for columns I do not care about UTF8 or 16 compliance - that will also mimic the same behavior I currently have on the SQL Server side. For anything that was nvarchar in SQL Server, I went ahead and created them as VARCHAR2 with the CHAR designation, with the same size (not double the value as was in SQL Server which the documentation says it gets translated to). I did this since we probably will need true UTF-8 compliance down the line, and since I had the hood open, it was easy enough to do. I could also have converted NVARCHAR(n) to NVARCHAR2(n) (and not n*2) as what was happening in the migration.
I tested strings in both cases, and I think I have my solution.

SQL query against tables on MS SQL Server and Oracle using Oracle BI

Hi All
I have two databases Oracle and MS SQL Server. I want to write a query statement which will retrieve data from both databases and publish this data into one report. That is I want to join/merge data from tables in both database into one report with one SQL Statement something like:
Select o.F1,o.F2, m.F1,m.F2
from
table@oracleServer o,
table@microsoftSQLServer m
where o.F1=m.F1;
Can Oracle BI Publisher do this?
Basically I want to query simultaneously two heterogeneous data sources in one SQL statement. Is there such a tool? I don't want to build a warehouse by moving data from SQL Server into Oracle or vice-versa. I don't want to duplicate data. I want to be able to query data at its source via 1 SQL statement.
How would one go about doing such a thing?
Many Thanks
Kubilay.

Hi Matt and Thomas
Many thanks for your replies.
Yes I have to do the join. Even worse I have to write an Aggregate query like this!
Select o.F1,o.F2, m.F1,m.F2, count(*)
from
table@oracleServer o,
table@microsoftSQLServer m
where o.F1=m.F1
group by o.F1,o.F2, m.F1,m.F2;
These are 2 different systems (hardware & software) which actually do the same job, they produce transactions for a common business entity. Kind of, both sell tickets for the same ABC ferry company.
I can not put them side by side on the dashboard, as I need to aggregate the data and present it maybe in a Oracle BI Report for Accounting and Financial reconciliation purposes.
The truth is, as it is. I can't change it, is too late.
I have to device a way to harvest both systems as they are. I don't want to move around data. I thought looking at Oracle BI I could write SQL against multiple Data Sources. I am struggling to find a way. As it seems that it can "SQL query" 1 data source at a time.
I have been hinted on another forum (OracleTURK) to use Oracle Transparent Gateways and Generic Connectivity. http://download.oracle.com/docs/cd/B19306_01/server.102/b14232/toc.htm
Shame, I have to pay licenses for OWB and Oracle Transparent Gateways. I thought DB vendors can do better. Why do I have to pay to access the other 50% of the market.
I can understand the performance implications this might have. Because of it I might even be forced at the end to move data (ETL) into a separate database, slice it into partitions and manage it that way. Pitty because currenlty I only need one report out of these systems but seems like will be dear to get.
Thank you for all your help.

TRANSFER DATA FROM MS-SQL SERVER TO ORACLE

hello everybody
can anyone tell me how 2 transfer or convert data from ms-sql server to oracle
is there any utility
if yes let me know .
thanks in advance

There are various options depending on how much data we're talking about, where you want the program logic, whether it's a one-time migration, etc.
Among the options
- Use SQL Server's DTS
- BCP the data from SQL Server into flat files and use SQL*Loader to load it
- Create a database link using Heterogeneous Services and Generic Connectivity to extract data from SQL Server
- Use the Oracle Migration Workbench, which is now integrated into SQL Developer
- Use an ETL tool like Oracle Warehouse Builder

Passing from MS SQL Server to Oracle. Options?

Hello,
We are going to be passing from MS SQL Server to Oracle (ver 10.2.0.3 on Windows Server 2003).
It looks like there is no Oracle tool which will translate TSQL code so that an Oracle database can read it.
What can be used to pass SQL Server DML statement TO Oracle? What are the options?
Thanks

Nell,
If you want to translate TSQL to Oracle PL/SQL you have a tool to do that.
This is Oracle SQL*Developer, you can download (version 1.5.1 build 54.40 )from this website:
http://www.oracle.com/technology/products/database/sql_developer/index.html
This is a free tool.
When you use SQL*Developer, you have the menu Migration/Translation Scratch Editor.
For example, you can create a connection directly to your SQL server db, display your TSQL procedures and then translate automatically to PL/SQL.
You can migrate automatically SQL SERVER database, or only several tables to Oracle.
If you have question about this tool, please go in the Database/SQL developer forum
I hope it helps you.

Mireille

Translate Stored Procedure from MS SQL Server to ORACLE 9i

Hi...
I work usually with MS SQL Server, and now I need to migrate an application from MS SQL Server to ORACLE 9i. I think to preserve most of User Interface made actually in MS Visual Basic .NET 2003 and change or "translate" all the MS SQL Server stored procedures to ORACLE 9i(most of business logic was code in Stored Procedures). So I need an advise of how to do that, if there are a tool for migration (tables, PK, FK, Rules, Defaults...etc) and, if possible, a procedure or tips for translate the stored procedures.
Thanks in advance....

Replication sql server to oracle

Hi all,
Anyone here good at replication?
Can you help me what freeware, or poor woman's script, or cheaper tool (compared to GG) to replicate table from sql server to oracle?
I tried googling it but it just too complex to understand :(
Please help....
Thanks,
zxy

There is a world of difference between a latency of 1 minute and a latency of 30 minutes. If you don't know for sure what sort of latency you can tolerate, you'll really need to figure out your requirements before anyone is going to be able to help.
If you can tolerate a 30 minute latency and you can identify changes that need to be replicated from the SQL Server side, you may be able to cobble something together by using Heterogeneous Services to create a database link to SQL Server and scheduling a job in Oracle to run every, say, 15 minutes to replicate the changes. Assuming that you don't want to buy the SQL Server gateway, that would involve using the ODBC gateway. If your Oracle database is on Windows, that's not too big of a deal. If you're on something other than Windows, that would either require that you license a SQL Server ODBC driver that runs on whatever operating system you use (which will likely cost less than GoldenGate but more than nothing) or it will require a non-standard configuration where the gateway is installed on the machine that SQL Server is running on (or you could introduce a third Windows box that just runs the ODBC Gateway).
