如题：vs2012中如何连接mysql数据库，求大神指教，最好有代码示例。谢谢。

string strSql="";//数据库连接字符串
SqlConnection conn = new SqlConnection(strSql);
conn.Open();

这样就连接上了

                        string strSql = "数据库连接字符串";
            SqlConnection conn = new SqlConnection(strSql);
            conn.Open();
            SqlCommand cmd = conn.CreateCommand();
            cmd.CommandText = "sql 语句";
            cmd.ExecuteNonQuery();

就是这样子了。。。。

严格地来说，首先你必须加载第三方库MySql.Data.dll，然后在对应的位置输入以下代码
MySql.Data.MySqlClient.MySqlConnection conn;
string myConnectionString;
myConnectionString = "server=127.0.0.1;uid=root;" + "pwd=12345;database=test;";
try
{
conn = new MySql.Data.MySqlClient.MySqlConnection();
conn.ConnectionString = myConnectionString;
conn.Open();
}
catch (MySql.Data.MySqlClient.MySqlException ex)
{
MessageBox.Show(ex.Message);
}
若还有不清楚或需要进一步了解，请加我微信号：chipembed 进行详聊。

JDBC有C++版本的SDK，下载一份吧

public ScheduleInfo query(int count) throws Exception {
    // TODO Auto-generated method stub
    String className = "oracle.jdbc.driver.OracleDriver";
    String url = "jdbc:oracle:thin:@localhost:1521:orcl";
    String user = "scott";
    String password = "tiger";

    Class.forName(className);
    Connection connection =null;
    PreparedStatement preparedStatement =null;
    ResultSet resultSet = null;
    String sql = "SELECT * FROM emp";

    connection = DriverManager.getConnection(url, user, password);
    preparedStatement = connection.prepareStatement(sql);
    resultSet = preparedStatement.executeQuery(sql);
    while(resultSet.next()){
        System.out.println(resultSet.getString(1));
    }
    return null;
}
