I have this MS SQL 2008 (Std) DB with all requiste code, e.g. sp, functions, views, triggers, etc. We have a mandate to convert the entire backend into Oracle 10G.  Due to time constraints, I would really appreciate a 3rd party app that actually works and converts from one platform to another.

Does anyone have any recommendation for a conversion app?

Thanks

there is no such tool, AFAIK.
there are some tools to help migation of the tables, indexes and view.
however, procedures, functions, triggers are just too different in many cases for a automatic conversion.

What about Oracle SQL Developer for Windows?  Isn't this Oracle's tool to help with the conversion?

Thx

Kindly check this one out for Data Migration:

http://www.swissql.com/products/datamigration/data-migration.html

For DDL Migration:

http://www.swissql.com/products/sqlserver-to-oracle/sql-server-to-oracle.html

Above doesn't support SQL Server 2008 and hence some manual intervention is required.

Kindly check this one too from Oracle

OK...I must be missing something then...look at the info below from Oracle's website (what am I missing)?

it simplifies the conversion, it doesn't do it all for you
it's just a tool to help you do it

certain you can write in oracle which you can't even write in mssql
some queries for instance you can rewrite a lot simpler in oracle
just consider you want the max in the current record taken from the next record to the last record
max(x) over (partition by y,z order by a,b range between following and unbounded following)

you'll have to review all your stored procs/funcs/ triggers

stored procs do a select at the end to return a recordset
this doesn't work in oracle, you need an out sys ref cursor as parameter
all selects must return data into a parameter in pl/sql code
