![]() Open a connection − Requires using the DriverManager.getConnection() method to create a Connection object, which represents a physical connection with the database.Įxecute a query − Requires using an object of type Statement for building and submitting an SQL statement to the database.Įxtract data from result set − Requires that you use the appropriate ResultSet.getXXX() method toĬlean up the environment − Requires explicitly closing all database resources versus relying on the JVM's garbage collection. Most often, using import java.sql.* will suffice. Import the packages − Requires that you include the packages containing the JDBC classes needed for database programming. There are following six steps involved in building a JDBC application − This will show you how to open a database connection, execute a SQL query, and display the results.Īll the steps mentioned in this template example, would be explained in subsequent chapters of this tutorial. This chapter provides an example of how to create a simple JDBC application.
