What's the best type 4 Oracle JDBC driver? What I want: Stable, few bugs and quick fixes Should warn about the usual JDBC pitfalls (connection leaks, etc) Must support CLOB [EDIT] My main issues with the "free" Oracle Type 4 driver are: I spent two weeks hunting down a cursor leak in the CLOB support code (closing the stream would...
I need to test a JDBC connection to a database. The java code to do that should be as simple as: DriverManager.getConnection("jdbc connection URL", "username", "password"); The driver manager will lookup the appropriate the driver for the given connection URL. However I need to be able to load the JDBC driver (jar) at runtime. I.e I d...
I'm writing an application which has to be configurable to connect to Oracle, SQL Server and MySQL depending on client whim. Up till now I'd been planning on using the JDBC-ODBC bridge and just connecting to the databases using different connection strings. I'm told this is not very efficient. Is there a pattern or best practice for ...
We are upgrading our servers to SQL Server 2005 from SQL Server 2000. We currently use the jtds drivers. I'm interested to know what peoples opinions are of the different jdbc drivers available (in particular the latest Microsoft driver), how they perform with SQL Server 2005 and any other lessons from your collective experience.

We have a problem with the Euro character when saving and retrieving it from a Oracle 10g using the Oracle 10.2.0.3 JDBC driver. The problem only occurs during a JUnit test running under Linux. The Euro characters returned from database after saving are total screwed up. Oracle has been configured to use character set "WE8MSWIN1252". Cou...

I'm new to java development, and was happy to see how much easier the database implementation was when it comes to supporting several platforms, compared to the php environment I'm used to. There is, however, one thing I'm confused about - I read everywhere I have to do a runtime-include of the database driver I want to use, ie: Class....

I can't for the life of me get the library located here: http://www.xerial.org/trac/Xerial/wiki/SQLiteJDBC and zentus.com to run in native (JNI) mode on OSX 10.5. If I query the driver for the mode it always says "pure", which means it's running in nested VM mode and pure java code is running to query the sqlite database, which is slower...

Why the heck does Oracle offer a different(!) version of the JDBC driver, e.g. ojdbc14.jar, for every(!) database version? The files all have different sizes and thus probably different content. background: We get a random and seemingly irreproducible error saying "invalid number" when saving data (we guess it's the Timestamp). But it's...
