oledb连接方式中，绑定变量如何做？
如 SELECT * FROM Customers WHERE CustomerID =:CustomerIDvalue
如何通过参数名叫把CustomerIDvalue 传进去

[解决办法]
oledbcommand oleCmd=new oledbcommand();
oleCmd.CommandText= "SELECT * FROM Customers WHERE CustomerID =@CustomerIDvalue ";
oleCmd.Parameter.Add(new Parameter( "@CustomerIDvalue ",CustomerIDvalue));
然后执行oleCmd用DataReader或DataSet接收记录
[解决办法]
按着顺序写就行了
com.Parameters.Add( "? ",类型).Value = "XXX ";
