We have listed down three forms of DriverManager.getConnection() method to create a connection object. Jdbc:sybase:Tds:hostname: port Number/databaseNameĪll the highlighted part in URL format is static and you need to change only the remaining part as per your database setup.
Jdbc:db2:hostname:port Number/databaseName Jdbc:mysql://hostname/ Number:databaseName

A database URL is an address that points to your database.įormulating a database URL is where most of the problems associated with establishing a connection occurs.įollowing table lists down the popular JDBC driver names and database URL. GetConnection(String url, String user, String password) GetConnection(String url, Properties prop) Overloaded DriverManager.getConnection() methods − For easy reference, let me list the three The following example uses registerDriver() to register the Oracle driver −ĭriver myDriver = new () ĭriverManager.registerDriver( myDriver ) Īfter you've loaded the driver, you can establish a connection using the DriverManager.getConnection() method. You should use the registerDriver() method if you are using a non-JDK compliant JVM, such as the one provided by Microsoft. The second approach you can use to register a driver, is to use the static DriverManager.registerDriver() method. ("Error: unable to instantiate driver!") Īpproach II - DriverManager.registerDriver() ("Error: access problem while loading!")

You can use getInstance() method to work around noncompliant JVMs, but then you'll have to code for two extra Exceptions as follows −Ĭlass.forName("").newInstance() The following example uses Class.forName( ) to register the Oracle driver −Ĭlass.forName("")

This method is preferable because it allows you to make the driver registration configurable and portable. The most common approach to register a driver is to use Java's Class.forName() method, to dynamically load the driver's class file into memory, which automatically registers it. You can register a driver in one of two ways. You need to do this registration only once in your program. So it can be utilized as an implementation of the JDBC interfaces. Registering the driver is the process by which the Oracle driver's class file is loaded into the memory, You must register the driver in your program before you use it. Import java.math.* // for BigDecimal and BigInteger support Import java.sql.* // for standard JDBC programs To use the standard JDBC package, which allows you to select, insert, update, and delete data in SQL tables, add the following imports to your source code − The Import statements tell the Java compiler where to find the classes you reference in your code and are placed at the very beginning of your source code.
Register JDBC Driver − This step causes the JVM to load the desired driver implementation into memory so it can fulfill your JDBC requests.ĭatabase URL Formulation − This is to create a properly formatted address that points to the database to which you wish to connect.Ĭreate Connection Object − Finally, code a call to the DriverManager object's getConnection( ) method to establish actual database connection. Import JDBC Packages − Add import statements to your Java program to import required classes in your Java code. The programming involved to establish a JDBC connection is fairly simple. After you've installed the appropriate driver, it is time to establish a database connection using JDBC.
