creating JDBC connection

This document discusses how to create a JDBC connection to a database in Java. It explains that the Java Database Connectivity (JDBC) API uses the java.sql package and DriverManager class to connect to databases. It provides steps to register an Access database file as an ODBC data source, load the JDBC-ODBC bridge driver, and obtain a Connection object using the jdbc:odbc URL. Sample code files called ConnectMe.java and ConnectMe1.java are included to demonstrate explicitly and implicitly loading the JDBC driver class.

• Register testdb.mdb with the ODBC Datasource Administer
on your PC. Instructions:
– Open Control Panel and select ODBC Data Sources
[32bit] (on XP under Administrative Tools). You will
get the window shown on the right. Click on Add.](https://image.slidesharecdn.com/21607071401201160732-200531101526/85/creating-JDBC-connection-4-320.jpg)

- 2. 2 • JDBC: Java Database Connectivity kit • Package: java.sql • DriverManager: class for making connection to databases • Connection: interface for communicating with databases once connection has been established. • Other interfaces: Statement, ResultSet, DatabaseMetaData, ResultSetMetaData, SQLException, ….etc.

- 4. 4 • Register testdb.mdb with the ODBC Datasource Administer on your PC. Instructions: – Open Control Panel and select ODBC Data Sources [32bit] (on XP under Administrative Tools). You will get the window shown on the right. Click on Add.
- 5. 5 – Select Microsoft Access Driver and then click on Finish. You will get the window shown on the right. – Provide a name for the data source, say TestDB. – Click and Select and select testdb.mdb from file system (picture on the next page)
- 6. 6 – Then you see the picture on the right. Simply click on OK and the registration is complete. – Thereafter the database testdb.mdb is known as TestDB to the ODBC Datasource Adminstrator. – For JDBC, URL for the database is: jdbc:odbc:TestDB
- 7. 7 • Register JDBC driver (sun.jdbc.odbc.JdbcOdbcDriver ) with DriverManager – Method 1: • set system property jdbc.drivers System.setProperty("jdbc.drivers", "sun.jdbc.odbc.JdbcOdbcDriver"); • At initialization, DriverManager loads all driver classes referenced in jdbc.drivers – Method 2: Load driver explicitely at any time Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); A call to forName("X") causes the class named X to be initialized.

- 8. 8 • Connection examples – ConnectMe.java: register JDBC driver using the second method – ConnectMe1.java: register JDBC driver using the first method • Note. Examples (including testdb.mdb) in this topic are packaged in the zip. See the code page
