我有这个代码，我从昨天起就一直在努力，但是没有按预期工作。
现在的问题是，我有2个数据集来从数据库生成信息到Reportview，然后在一个数据集上，我使用2个表（Transaction和Account_info）来生成数据。两者都正确地提供了他们的信息，没有问题，但现在问题来了。
如果我将标识符（账号）搜索到生成账单对A先生说，它会显示A和B先生的详细信息，然后如果我为B先生设置标识符，它将显示B先生的账户对账单和A.先生我只想让它为一个人发表声明。即。如果A先生的账号只显示A先生的数据，而B先生的账号只显示B先生的数据。
数据集是DataSet1，我希望它只显示一个客户的信息
我的代码如下所示：

好的我修好了。我不得不修复一些非常错误的查询，它现在正如我所料。如果某人将来需要这样的东西。
