1. Build
> javac Sample.java
> java -classpath ".;sqlite-jdbc-(VERSION).jar" Sample # in Windows
or
> java -classpath ".:sqlite-jdbc-(VERSION).jar" Sample # in Mac or Linux
name = leo
id = 1
name = yui
id = 2
2. Usage
Sample.java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class Sample
{
public static void main(String[] args)
{
Connection connection = null;
try
{
// create a database connection
connection = DriverManager.getConnection("jdbc:sqlite:sample.db");
Statement statement = connection.createStatement();
statement.setQueryTimeout(30); // set timeout to 30 sec.
statement.executeUpdate("drop table if exists person");
statement.executeUpdate("create table person (id integer, name string)");
statement.executeUpdate("insert into person values(1, 'leo')");
statement.executeUpdate("insert into person values(2, 'yui')");
ResultSet rs = statement.executeQuery("select * from person");
while(rs.next())
{
// read the result set
System.out.println("name = " + rs.getString("name"));
System.out.println("id = " + rs.getInt("id"));
}
}
catch(SQLException e)
{
// if the error message is "out of memory",
// it probably means no database file is found
System.err.println(e.getMessage());
}
finally
{
try
{
if(connection != null)
connection.close();
}
catch(SQLException e)
{
// connection close failed.
System.err.println(e.getMessage());
}
}
}
}
How to Specify Database Files
Here is an example to select a file C:\work\mydatabase.db (in Windows)
Connection connection = DriverManager.getConnection("jdbc:sqlite:C:/work/mydatabase.db");
A UNIX (Linux, Mac OS X, etc) file /home/leo/work/mydatabase.db
Connection connection = DriverManager.getConnection("jdbc:sqlite:/home/leo/work/mydatabase.db");
How to Use Memory Databases
SQLite supports on-memory database management, which does not create any database files. To use a memory database in your Java code, get the database connection as follows:
Connection connection = DriverManager.getConnection("jdbc:sqlite::memory:");
