sqlite 建库建表等

　　使用 sqlite 建库建表操作
　　1. 使用可视化的工具建立. 我常用的是 SQLite Expert Personal ...
　　http://www.sqliteexpert.com/ 可下载
　　2. 通过代码建立

import java.sql.*;
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();
}
}

　　注意:
　　1. Connection conn =  DriverManager.getConnection("jdbc:sqlite:test.db");
如果指定名称所代表的数据库不存在则自动创建.如果存在则直接使用.
　　2. stat.executeUpdate("drop table if exists people;");
    stat.executeUpdate("create table people (name, occupation);");
通过代码来创建删除表. 没啥好说的了.
　　其他的也没什么太多要注意的了.
