如果供应商没有提供驱动程序，我们可以使用jdbc吗？

Question

This is just a theoretical question for my own knowledge. Most of the RDBMS databases that we use have vendor provided JDBC driver but if there is a DB for which vendor has not provided any driver, is it still possible to connect to that database using JDBC? Does that mean that we will have to write our own driver or is there any other way?

Answer 1

As Jan pointed out, there's a JDBC-ODBC Bridge that allows you to write JDBC code provided that there's an ODBC driver for the database, if for some reason there doesn't exist a JDBC driver for the database. I remember years ago it being very popular to connect to MS Access , but even that's no longer the best way to go.

However being in a situation where you don't have a JDBC driver should be very rare, and if you should encounter that kind of situation, maybe it would be a good time to migrate to a more modern database in any case..
