Question

我在AS400上运行ODBC数据库。我创建了一个连接字符串来连接数据库并运行查询。当我将程序编译为32位时，我的所有查询都运行正常，但当我将它们编译为64位时，我得到一个溢出异常。不幸的是，我必须将我的程序编译为64位。

可能导致此问题的原因以及我该如何解决？

更多信息：
我正在使用的驱动程序是iSeries Access ODBC Driver
我的所有数据库列都是字符串或小数
我使用的是连接字符串而不是DNS 我正在使用的连接字符串是
“Driver = {iSeries Access ODBC Driver}; uid = XXX; data provider = ODBC; system = XXX; dbq = XXX; pwd = XXX”

我感谢任何帮助。

代码如下所示：

MPDCHFTableAdapter configs = new MPDCHFTableAdapter();
variants = configs.GetDataByProduct("98.M1BODY");

我发现使用OLE驱动程序而不是ODBC可以防止出现此问题。仍不确定问题是什么。
