表的Rylb列是后来加上，再改方法时，行35少了一个逗号，程序运行没有错误，但是出现数据错误。
原来生成了sql语句如下：

update T_Ryzhzhxx set CardNo=@CardNo,ChgNo=@ChgNo,GameNo=@GameNo,HdNo=@HdNo,SfNo=@SfNo,Shbdw=@Shbdw,State=@State,SfRemark=@SfRemark,SQNo=@SQNoRylb=@Rylb where Ryzhzhid=@Ryzhzhid 

于是字段SQNO中为0;
@SQNoRylb=@Rylb当两个参数值不等时，SQNo=0了。再加上OleDB不是按参数名来加载参数值，而是按参数顺序。就出现错误的数据
