Will Oracle flatten multiple between clauses if they have overlapping data? In my application, users can create dynamic search terms, so it's possible that there could be overlapping data. Will Oracle optimize the SQL for me or do I have to calculate it before I create the SQL? i.e. Select id from xxtable WHERE id (BETWEEN 10 AND 20)...
Here's a simplified pseudo-code version of what I'd like to be able to do in PL-SQL (Oracle): DECLARE mylist as ARRAY BEGIN mylist (1) := '1' mylist (2) := '3' ... SELECT * FROM aTable WHERE aKey IN mylist; END; The SELECT should return the matching records for mylist(1), mylist(2) etc. It should be similar to ORing all ...
I need to diagram an oracle database and I am hoping to find some good tools that are either cheap, or free. Ideally the tool should allow me to draw the relationships between the tables, as well as remove unwanted tables from the diagram. I already have access to MS Visual Studio 2008 as well as SSMS 2008, but I don't believe either w...
This isn't really a programming question, but more of a systems administration one. It's specific to Oracle's Application Server product, which has many names -- e.g. OAS, iAS, OHS, Oracle HTTP Server, etc. Basically it's just a hacked version of Apache with a bunch of extensions for Oracle-specific things. After struggling for several ...

Has anyone tried migration from Microsoft OracleClient to dotConnect for Oracle? Is it realy so easy (as they wrote at their blog http://www.devart.com/blogs/dotconnect/?p=67) or just another marketing trick? I've tried ODP.NET, but it seems to me that its interface differs from the standard one. ...

Hi! I am developing an application which should work under different languages (german, spanish, etc). The application uses an Oracle DB. I have CRUD business processes and I have the standard views (create, edit, show, list).

My database (10gR2) is single-byte (NLS_CHARACTERSET = WE8DEC). I have a Unicode XML file that I would like to parse. If I read the file into a CLOB and try to convert it to an XMLType, Oracle chokes when the XML contains special characters (in this case Norwegian characters such as "øæå"). ORA-31011: XML parsing failed ORA-19202: Erro...

I'm using Oracle's JDBC thin driver (10.2.0.3) for connecting to an Oracle 10g database. I'd like to get information about the database columns, so I use ResultSetMetaData. The most important information I need is the type of the column and the length, so I use getColumnType, getPrecision, and getScale methods. It works for a simple que...
