推荐答案

这将取决于您在应用程序中所拥有的功能.如果它们看起来像是图像，那么varbinary(max)将是一个不错的选择.如果他们需要其他信息，则可能需要将它们存储在两个字段中，以便在使用之前将它们分开.

That''s going to depend on what you have them as in your app. If they are images as seems likely, then varbinary(max) would be a good choice. If they need additional info then you might want to store them in two fields to make separating them before use easier.
