/**
 * Extended ADODB class
 *
 * Include all ADODB had, and add a little others.
 *
 * Piror use this class' method and property, if the get/set/call target
 * is not exists, use original ADODB's, this can be done by php's mechematic
 * of overload __call __get __set.
 *
 * 这似乎是extend ADODB的一种比较好的方式，比官方网站文档上给的按不同数据库来继承子类的方式，
 * 我认为要更方便一些。缺点是没有对RecordSet对象进行处理。
 *
 * Adodb for Sybase bug:
 * Affected_Rows() in windows 2003 不可用，httpd 进程会出错中止
 *
 * 执行sql查询的系列更改中，限定系统/HTML/PHP使用$sSysCharset指定的编码，涉及函数列在__call()中，
 * 但一些通过数组等其它方式传递参数的ADODB方法仍然无法通过这种方式实现sql编码自动转换。
 *
 * 执行返回的数据还是需要转码的，不过返回数据的种类太多，放在应用中实现更简单一些，这里不自动执行，
 * 只提供一个EncodingConvert方法供用户调用。
