无意中发现的，C#/Java连接sqlite与使用技巧。看了下，还挺不错的。与大家分享一下。
1）下载sqlite jdbc驱动http://www.xerial.org/maven/repository/artifact/org/xerial/sqlite-jdbc/
2）将下载的驱动加入eclipse项目的built path中
3）示例代码：
复制代码 代码如下:
package com.hedalixin;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;
public class test {
/**
* @param args
*/
public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub
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();
}
}
2. C#连接sqlite
2.1 使用SQLITE.NET
SQLite.NET也是一个数据访问组件，其中的System.Data.SQLite 就好像是.NET自带的System.Data.SqlClient一样。里面包含了connection、command等数据访问的常用对象，只是他们前面都有一个前缀sqlite。
1）下载System.Data.SQLite，下载地址http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
2) 通过Add References引用SQLite ADO .NET安装目录的bin目录下的System.Data.SQLite.DLL。
3)创建表、读取数据等和Access或MS SQL没多大区别
复制代码 代码如下:
//创建一个数据库文件
string datasource="h:/test.db";
System.Data.SQLite.SQLiteConnection.CreateFile(datasource);
//连接数据库
System.Data.SQLite.SQLiteConnection conn = new System.Data.SQLite.SQLiteConnection();
System.Data.SQLite.SQLiteConnectionStringBuilder connstr = new System.Data.SQLite.SQLiteConnectionStringBuilder();
connstr.DataSource = datasource;
connstr.Password = "admin";//设置密码，SQLite ADO.NET实现了数据库密码保护
conn.ConnectionString = connstr.ToString();
conn.Open();
//创建表
System.Data.SQLite.SQLiteCommand cmd = new System.Data.SQLite.SQLiteCommand();
string sql = "CREATE TABLE test(username varchar(20),password varchar(20))";
cmd.CommandText=sql;
cmd.Connection=conn;
cmd.ExecuteNonQuery();
//插入数据
sql = "INSERT INTO test VALUES('ekinglong','mypassword')";
cmd.CommandText = sql;
cmd.ExecuteNonQuery();
//取出数据
sql = "SELECT * FROM test";
cmd.CommandText = sql;
System.Data.SQLite.SQLiteDataReader reader = cmd.ExecuteReader();
StringBuilder sb = new StringBuilder();
while (reader.Read())
{
sb.Append("username:").Append(reader.GetString(0)).Append("\n")
.Append("password:").Append(reader.GetString(1));
}
MessageBox.Show(sb.ToString());
