数据库查询中的特殊字符的问题
在进行数据库的查询时，会经常遇到这样的情况：
　　例如想在一个用户数据库中查询他的用户名和他的密码，但恰好该用户使用的名字和密码中有特殊的字符，例如单引号，“|”号，双引号或者连字符“”。
　　例如他的名字是1"test，密码是A|900
　　这时当你执行以下的查询语句时，肯定会报错：
SQL = "Select * FROM SecurityLevel Where UID=""  UserID  """
SQL = SQL  " AND PWD=""  Password  """
　　因为你的SQL将会是这样：
Select * FROM SecurityLevel Where UID="1"test" AND PWD="A|900"
　　在SQL中，"|"为分割字段用的，显然会出错了。现在提供下面的几个函数专门用来处理这些头疼的东西：
