使用jdbc連接SQLite數據庫的示例代碼

SQLite是一個單文件的數據庫，在單用戶情況下是非常小巧實用的。

用java如何連接sqlite呢？首先需要下載sqlite的jdbc驅動程序。

下載驅動程序之后在程序中引用此jar包，然后就可以使用sqlite數據庫了。

如下面的例子，我會創建一個test.db的文件，然后創建一個people表，并在people表中插入一條數據, 然后在從people表中取出所有數據。

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;

public class Test {
    public static void main(String[] args) throws Exception {
        Class.forName("org.sqlite.JDBC");
        Connection conn = DriverManager.getConnection("jdbc:sqlite:test.db");
        Statement stat = conn.createStatement();
        stat.executeUpdate("drop table if exists people;");
        stat.executeUpdate("create table people (name, occupation);");
        PreparedStatement prep = conn.prepareStatement(
            "insert into people values (?, ?);");

    prep.setString(1, "Gandhi");
    prep.setString(2, "politics");
    prep.addBatch();
    prep.setString(1, "Turing");
    prep.setString(2, "computers");
    prep.addBatch();
    prep.setString(1, "Wittgenstein");
    prep.setString(2, "smartypants");
    prep.addBatch();

    conn.setAutoCommit(false);
    prep.executeBatch();
    conn.setAutoCommit(true);

    ResultSet rs = stat.executeQuery("select * from people;");
    while (rs.next()) {
        System.out.println("name = " + rs.getString("name"));
        System.out.println("job = " + rs.getString("occupation"));
    }
    rs.close();
    conn.close();
}
