出现System.Data.OracleClient.OracleException: ORA-01036: 非法的变量名/编号
问题
可能之一就是你的名称不对应
比如:xwlx 写成:xxlx所引起的

或则        // 客户类型,客户编号,客户名称,开户行,账户,税号,地址,邮编,电话号码,手机,传真,邮箱,联系人,客户生日,特点,备注,更新日期,更新人,SN
        String sqlUpdate = "UPDATE kehuxinxi SET 客户类型=:khlx,客户编号=:khbh,客户名称=:khmc,开户行=:khh,账户=:zh,税号=:sh,地址=:dz,邮编=:yb,"
                            + "电话号码=:dhhm,手机=:sj,传真=:cz,邮箱=:yx,联系人=:lxl,客户生日=:khsr,特点=:td,备注=:bz,更新日期=:gxrq,更新人=:gxr"
                            + " WHERE SN=:sn";
其中少写了个,比如电话号码=:dhhm,手机=:sj, 写成 电话号码=:dhhm 手机=:sj,
