What's the difference? More specifically as you can see from the code, there are two differences in the code:. The name of the JDBC driver. The JDBC URL used to connect to the database. Everything else in the two source code listings - except for the comment at the top - is identical. Here's a slightly more detailed discussion of the two differences: 1.The JDBC Driver The name of the JDBC driver will be supplied to you by your database vendor. As you can see in the class.forName statements, these names will vary.
In the first case we're using the mSQL-JDBC driver. In the second case we're using the JDBC-ODBC Bridge driver supplied with the Interbase server. The URL The syntax of the DriverManager.getConnection method is: DriverManager.getConnection(String url, String username, String password); The username and password are the normal names you use to log into your database.
The URL you use will again vary with the database you use. In both examples shown, we're establishing a connection to a database named contactmgr. (We'll use this database for all of our examples in this series of JDBC articles.) If you stick with standard SQL commands, it can be very easy to switch from one database server to another.
In fact, I've heard from several developers who are using mSQL to prototype their software (because it's so inexpensive), and then switching to another commercial vendor when it's time to take their product 'live'. For your reference, I just created this page of. What's next Now that you know how to connect to a database using Java & JDBC, you’ll probably want to read one of these two tutorials:. In summary, I hope this series of Java/JDBC tutorials is helpful.
