Sending SQL null back to Oracle database

I am trying to find out how to send a SQL NULL back to a Oracle database using a PreparedStatement in a Java Server Page. What do I need to set my variable to be able to do this. Can anyone help.
Thanks in Advance, Brian

Thankyou but how do I use it. ie. How do I use the SQL Type constant in the setNull statement.
I am currently doing the following:
pstmt.setNull(13,VARCHAR);
I do I use VARCHAR as a int constant. Can you give me an example.
Thanks.

Run sql statements in PL/Sql Developer without installing Oracle database?

Hi all,
I wish to ask is there any possibility to run Run sql statements in PL/Sql Developer without installing Oracle database?

Hello Jimmy,
this is the forum for the tool SQL Developer and, as the title says, *(Not for general SQL/PLSQL questions)*.
PL/Sql Developer is not an Oracle tool, but from allound allroundautomations.
And you need access to a database to run SQL statements. This does not need to be one installed by yourself.

How to migrate an existing Microsoft SSIS deployment if it is decided to replace SQL Server with an Oracle database?

Hi Oracle Gurus!
Currently, I am designing an ETL solution that transforms and loads a lot of data from flat files and sends it to an SQL Server 2008 R2 database for storage. However, at a future point of time, it may be decided to add or even replace SQL Server with an Oracle 11g database.
Currently, I am writing script transforms in C# to dynamically generate SSIS packages to tansform and load the data into SQL Server. But considering that in future, an Oracle 11g or 12c database might be added to, or replace the SQL Server database, how do I make my script transforms (or whatever else I am developing currently for SQL Server) reusable to the extent possible?
Or more precisely, what steps do I take, from an Oracle point of view, to ensure that any future migration of data to an Oracle database would be smooth to the extent possible?
Looking up to my Oracle Gurus for enlightenment in this matter!
Novice Kid

When you're writing your on C# code to load data into the SQL Server you have to modify the routines so that they will work with Oracle.
One approach is to use the extproc agent which would allow you to directly call external programs with all the logic in it to perform the load of your files and to put the data into the Oracle database. Another option would be to use utl_file package (or equivalents) which will allow you to open external files from your Oracle database and to directly read its content and then to pass it to the related tables.

Querying SQL server table from Oracle database 11g

Hi all
We are using oracle database 11g R2 on REL 5 and i have an SQL server database used by one of our application.
In my Oracle database, i want to query one table in my SQL server database and to link it in a table in Oracle database to compare data.
Is there a way like database link or something else to do this need>
Please send a link or pots here step by step the way on how to accomplish my query.
Thank you.

Yes, you can set up your SQL Server as an external database link, using Oracle Heterogeneous Services with SQL Server as an ODBC connection (easier to do if your Oracle server is a Windows server, a little more tricky if your Oracle server is *nix based)
Here's the documentation... for 11gR2

MS SQL Procedure Call from Oracle Database

I have Oracle Database 11g connected to MS Sql Server 2008 via dg4msql, and need to execute procedure on MS Sql with parameters from Oracle, and get dataset (table) as a result.
I'm not sure is it possible to call procedure directly from Oracle; One solution would be make function on MS SQL, and put select on procedure from Oracle, but what with parameters?
Is there some possibility to call this procedure from Oracle and get this dataset as a cursor?
Thanks in advance!

Yes, of course I have DB Link in Oracle and procedure in SQL Server.
Btw, I can select data from SQL Server table.
I made one function in SQL Server, and I can not make select on this function, but in SQL Server I made view as select * from function_name, and select on this view from Oracle works. But problem is I have to call this procedure or function with parameters, and with view I can not do this.
So, I must call procedure or function with parameters directly. I made all by the book (Oracle® Database Gateway for SQL Server User’s Guide), but probably I miss something...

There are a few bugs for SQL Plan Management (SPM) on 11.2.0.2 (see below). The slowness and non-peeked binds issues seem very problematic. I've seen a few bloggers recommend to not use SPM unless your at Oracle Database 12c.

Any recommendation from the community on whether I should capture and use SQL Plan Management with 11.2.0.2? Why, why not? If there's other relevant information needed, let me know.

Native SQL to an external oracle database

Hello experts,
     I like to read some data from an external oracle database with native sql statements.
Which prerequisites are neccessary to do so?
In detail: which customizing must be performed?
Wich authorizations are necessary on the local SAP-system and on the oracle-site?
Many thanks for your help!
         Best regards
                            Elmar

first, you need the SAP database library for Oracle. on Windows, filename is dboraslib.dll
then, you create a user ID on your external database
then ,you configure table DBCON

Error messages when sending date-time stamp to Oracle Database

I have a complex application that communicates with an Oracle database. One of the table values that gets written to the table is a date-time stamp. Until recently, the user only required a date, and this was never an error. (The format String used was %d-%b-%Y) Now they need a time-stamp as well, so I attempted to edit the format string input of the format date/time string function to include the time. I have tried numerous format strings, each of which returns an error on execution. Depending on which format I use, I get one of 3 different error messages. The really odd thing is that both the date and time always get stored in Oracle without any problem (regardless of what date-time I use, as long as I include the date and any part of a time stamp - I get the entire timestamp even if I only include %I for the hour). The only issue is that LabVIEW generates an ODBC error if I try to include the time to the date-time stamp. In other words, teh date/time stamp writes to the Oracle database, but an ODBC error occurs every time. I've included a word doc with screen captures of the format strings used, the resultant date/time stamps written to Oracle and the error messages generated within LabVIEW. Any advice would be most appreciated.
Attachments:
Summary of ODBC Error messages related to date-time stamp.doc ‏65 KB

Oracle has a standard date format: 12-Mar-2009 that it accepts as a string, but if you want more than that, you need to use the todate() function. I used this string going into the standard LabVIEW ''Format date/time sting vi'
to_date('%d-%b-%Y %H:%M:%S', 'DD-MON-YYYY HH24:MIS') to create the value needed for Oracle.
Then I use standard format string to create SQL: insert into mytable (mydate) values(%s) and select * from my table where mydate = %s using the string above for %s.
I think you can also define a global format for all time strings but I haven't bothered figuring that out.

How to Migrate Stored procedure on Sql server 2008 to Oracle Database

Guys, I need help vey badly as I am new in this field.
Problem is that, I have to migrate stored procedure on Sql server 2008 to oracle Oracle database:
Whole scenario--
1. Sql Server 2008 application on Windows server (source machine)
2. I have to migrate 70 Stored Procedure
3. To Oracle Database on Linux machine (Target machine)
Any method (no problem)
Please, help me or give me any reference as I don't know which keyword is differ in both database.
Thanks in advance

Hi,
You could the free Oracle SQL*Developer to do this.
There is information and a download link here -
Oracle SQL Developer</title><meta name="Title" content="Oracle SQL Developer"><meta n…
and information on using it for migrations here -
http://www.oracle.com/technetwork/database/migration/index-084442.html
You could use it in 2 ways -
1. Go through a migration but just pull the stored procedure code from the file created after you generate the SQL from the SQL*Server database
2. Use the scratch editor accessed from -
- Tools - Migration - Scratch Editor
and paste the SQL*Server stored procedure code into the window and it will convert it to Oracle code. The tool is very good but may have problems if you have very complicated procedures that use SQL*Server specific utilities.

How to migrate Azure SQL Codefirst DB to Oracle database?

Hi,
we have been developing a Web application with Windows Azure Code first SQL DB using Code first approach.
In the future we want to migrate our Azure SQL Code first DB to Oracle. If we migrate it to Oracle, does the application works fine? or do we need to do any additional actions in migrating from Azure SQL Code first db to Oracle DB?
It would be great if anyone provides me complete information on this.

Hi,
You should be able to move the Azure SQL Code First Database to Oracle Database. You will have to make minor changes, for e.g connection string.
Please have a check on the below link which talks about using Entity Framework 6 Code First with Azure SQL database as a backend. It will give you an idea on how to approach your migration.

I have a SP in SQL Server which will return a Result Set.
My requirement is to call that procedure in ORACLE using DB Link and insert that resultset(Data) in the temp table.First you need to setup Oracle to SQL Server connectivity. To do that you can either use HS - heterogeneous connectivity which comes for free or use Oracle Transparent Gateway which is not free. HS uses ODBC, so if your Oracle database in not on windows, you'll have to get ODBC SQL Server driver for Unix/Linux (e.g. from EasySoft). Since SQL Server selecting from table function syntax is different from Oracle's you will have to, if you use HS, to use DBMS_HS_PASSTHROUGH package. I never worked with Oracle Transparent Gateway to SQL Server, so I don't know if and how it supports selecting from SQL Server table function.

Sending Long Raw Data to Oracle database through Stored Procedure

Hi,
I am trying to push data to Oracle 9i database through Stored Procedure via thin driver. It is going smoothly upto 29411 bytes. But it is not accepting for 53843 bytes and giving following error :
java.sql.SQLException: Data size bigger than max size for this type: 53843
Is it thin driver limitation? Can I solve it by using OCI driver? Or is there any other approach?
I tried creating connection pool in weblogic 7.0 through OCI driver. But I am not able to configure it. Is there any special way of configuration.
Quick response will be greatly appreciated.
Thanks
Sanjiv

It happens to me. But I am using CMP of Weblogic 7. If you write your own jdbc code, the following link may be helpful.
