This JDBC tutorial helps you write Java code to establish database connection with an Oracle database server – the first step to have Java applications working with one of the most popular database systems. Suppose you already had a version of Oracle database installed, such as Oracle Database Express Edition.Table of content:

Free oracle database express edition download. Development Tools downloads - Oracle Database 11g Express Edition by Oracle Corporation and many more programs are available for instant and free download.

1. Download JDBC driver library for Oracle database

Oracle JDBC Driver has been registered Trying to get a connection to the database Connection to the database has been established JDBC Driver Name: Oracle JDBC driver JDBC Driver Version: 11.2.0.4.0 Trying to get a list of all employees in employee table EMPLOYEEID: 1, John Tester EMPLOYEEID: 2, Gary Webber. Well I went to Oracle and installed 'Oracle Database Express Edition 11g Release 2(11.1) Then I went download the JDBC driver(s) as Jesper suggested. Well that stumped me as I have no idea which of these many JAR files I need. Keep in mind this is just for learning and I am using Eclipse to run my JAVA classes. Our website provides a free download of Oracle Client Express Edition 18.4.0.0. The most popular versions of the software are 18.4, 11.2 and 11.0. This free program is a product of Oracle Corporation. The latest version of Oracle Client Express Edition is supported on PCs running Windows XP/Vista/7/8/10, both 32 and 64-bit. 1 Using Java with Oracle Database XE. Oracle Database Express Edition (Oracle Database XE) is a relational database that you can use to store, use, and modify data.The Java Database Connectivity (JDBC) standard is used by Java applications to access and manipulate data in relational databases. Try the jdbc driver for java 7 ojdbc7.jar since Oracle does not have one for java 8 yet (most likely called ojdbc8.jar) K. Free cad cam software mac. Tsang CEng MBCS PMP PMI-ACP OCMJEA OCPJP The government thinks you are too stupid to make your own lightbulb choices. Jdbc:oracle: drivertype:username / password@ databasespecifier. The first part of the URL specifies which JDBC driver is to be used. The supported drivertype values for client-side applications are thin and oci. The brackets indicate that the user name and password pair is optional.

To make a Java program talks with Oracle database, we need to have the Oracle JDBC driver (OJDBC) present in the classpath. Click here to visit Oracle’s JDBC driver download page. Then select the JDBC driver version that matches Oracle database sever and JDK installed on your computer. Currently there are two main versions of OJDBC:- OJDBC 8: certified with JDK 8, for Oracle database 11g and 12c.- OJDBC 10: certified with JDK 10, for Oracle database 18c and 19c.NOTE:Oracle requires users to have an Oracle account for downloading, so you may have to register an account if you don’t have one.Extract the downloaded archive, and place the ojdbc10.jar file under your project’s classpath as usual as using any jar file.If you use Maven, add the following dependency to the pom.xml file:

2. JDBC database URL for Oracle database

The syntax of database URL for Oracle database is as follows:

jdbc:oracle:<drivertype>:@<database>

jdbc:oracle:<drivertype>:<user>/<password>@<database>

Where:

drivertype can be thin, oci or kprb.
database can be in the form of hostname:port:SID or a TNSNAMES entry listed in the file tnsnames.ora reside on the client computer. The default port is 1521.

Oracle categorizes their JDBC driver into four different types, as described in the following table:

Driver type	Usage	drivertype
Thin Driver	For client-side use without an Oracle installation	thin
OCI Driver	For client-side use with an Oracle installation	oci
Server-Side Thin Driver	Same as Thin Driver, but runs inside an Oracle server to access a remote server	thin
Server-Side Internal Driver	Runs inside the target server	kprb

According to Oracle, if your JDBC client and Oracle database server are running on the same machine, you should use the OCI Driver because it is much faster than the Thin Driver (The OCI Driver can use Inter Process Communication – IPC, whereas the Thin Driver can use only network connection).For example, if you want to connect user tiger with password scott to an Oracle database with SID productDB through default port on host dbHost using the Thin Driver, you can construct the URL as follows:If using the OCI Driver:If you have a TNSNAMES entry productionDB in the tnsnames.ora file, you can construct the URL as follows:For the Server-Side Thin Driver, use the same URL as the Thin Driver.For the Server-Side Internal Driver, use the following URLs:Because in that environment, the driver actually runs within a default session, and the client is always connected so the connection should never be closed.

3. Register Oracle JDBC driver

The Oracle JDBC driver class name is oracle.jdbc.OracleDriver.You can register this driver as follows:or:NOTE:Since Java 6 (JDBC 4.0), registering the driver explicitly as above becomes optional. As long as we put the ojdbc10.jar file in the classpath, JDBC driver manager can detect and load the driver automatically.

4. Establish connection to Oracle database

With JDBC, we can establish a database connection by calling the method getConnection() of the DriverManager class. There are three versions of this method:

- static Connection getConnection(String url)
- static Connection getConnection(String url, Properties info)
- static Connection getConnection(String url, String user, String password)

So we can have three ways for making a connection as follows:

Using only database URL for everything

In this method, we specify all connection properties in a single URL string, for example:

That uses the Thin Driver to connect the user tiger with password scott to the database SID productDB running on the same machine through the default port 1521.

Using database URL, username and password

In this method, we pass the username and password as additional arguments to the method getConnetion(), for example:

Using database URL and Properties object

In this method, we use a java.util.Properties object to hold username, password and other additional properties. For example:In this example, we are using the OCI Driver with a TNSNAMES entry ProductDB, and specifying an additional property defaultRowPrefetch which is the number of rows to prefetch from the server.

5. Java Connect to Oracle Database Example program

To demonstrate, we create a small example program below that establishes three different connections in 3 ways mentioned above, and finally close all the connections:That's Java code example for making connection to Oracle database server. For visual howtos, watch the following video:
