Question

我无法搞清楚这个堆栈跟踪，一切都在远离.NET，但由于它全部绑定到IT管理员不愿意升级的2000 MSSQL服务器，我仍然需要处理一些低如果出现问题，可以与之连接的优先级应用。我只看到一个堆叠，但这里似乎有两个。我也不知道它要检查哪个文件，因为问题通常在堆栈顶部？我主要做PHP，所以很多这个对我来说都不熟悉。

筹码在这里。

根据我的研究

该应用程序试图在列中存储比int类型允许的更多字节。我计划将表格列更改为nvarchar或bigint但是想知道这是否是我需要做的全部内容？ nvarchar会是更好的选择吗？

提前致谢。

Answer 1

int最大值范围为2^32，因此sign = -2147483648至2147483648或无符号0至4294967296您的值{{ {1}}，更大。您需要一个9000437060，它在SQL中是long

Answer 2

看起来你正在使用数据库中的值溢出int。尝试将您的c＃数据类型更改为long

varchar值'9000437060'的转换溢出了一个int列。超出最大整数值
