java连接sqllite代码

方法一：
import java.sql.*;
2 import org.sqlite.JDBC;
3
4 public class SQLiteTest {
5 public static void main(String[] args) {
6 try {
7 // The SQLite (3.3.8) Database File
8 // This database has one table (pmp_countries) with 3 columns (country_id, country_code, country_name)
9 // It has like 237 records of all the countries I could think of.
10 String fileName = "c:/pmp.db";
11 // Driver to Use
12 // http://www.zentus.com/sqlitejdbc/index.html
13 Class.forName("org.sqlite.JDBC");
14 // Create Connection Object to SQLite Database
15 // If you want to only create a database in memory, exclude the +fileName
16 Connection conn = DriverManager.getConnection("jdbc:sqlite:"+fileName);
17 // Create a Statement object for the database connection, dunno what this stuff does though.
18 Statement stmt = conn.createStatement();
19 // Create a result set object for the statement
20 ResultSet rs = stmt.executeQuery("SELECT * FROM pmp_countries ORDER BY country_name ASC");
21 // Iterate the result set, printing each column
22 // if the column was an int, we could do rs.getInt(column name here) as well, etc.
23 while (rs.next()) {
24 String id = rs.getString("country_id"); // Column 1
25 String code = rs.getString("country_code"); // Column 2
26 String name = rs.getString("country_name"); // Column 3
27 System.out.println("ID: "+id+" Code: "+code+" Name: "+name);
28
29 }
30 // Close the connection
31 conn.close();
32 }
33 catch (Exception e) {
34 // Print some generic debug info
35 System.out.println(e.getMessage());
36 System.out.println(e.toString());
37 }
38 }
39 }
