SQl Server 文件上传过程中是否有任何限制？

Answer 1

此错误是由您的 Web 服务器而不是 SQL 服务器引发的。

如果您使用的是 IIS，您可以修改 web.config 以允许上传大文件。

<configuration>
    <system.web>
        <httpRuntime maxRequestLength="xxxxxx" />
    </system.web>
</configuration>

对于 IIS 版本 7 及更高版本，请使用以下内容..

<system.webServer>
   <security>
      <requestFiltering>
         <requestLimits maxAllowedContentLength="xxxxxxx" />
      </requestFiltering>
   </security>
 </system.webServer>
