Can someone recommend a good, open source, standalone developer tool for querying SQL databases using JDBC and exporting the results to a file? I know a lot of database vendors provide their own tools, but I need one that will allow me to plug in my own custom JDBC driver and work against any database. A GUI is preferable, but not required.
Oracle's SQL Developer is disqualified because it seems to work only with a pre-canned set of JDBC drivers. I have also looked at the list of tools at Java-Source.net, but I'm hoping someone can help me narrow down the list based on personal experience. And it needs to be standalone so non-developers can use it, too, which disqualifies Eclipse plug-ins. Thanks!
