Azure存储表中的InsertOrUpdate与InsertOrMerge，有什么区别? [英] InsertOrUpdate vs. InsertOrMerge in Azure Storage Tables, what is the difference?

问题描述

在查看了这两种方法的Microsoft文档之后，我发现两者之间没有任何区别，或者也许我错过了一些东西.我已经对InsertOrMerge进行了一些试验，但是它所做的全部将新数据替换为旧数据.

After looking at the Microsoft documentation for both of these methods, I don't see any difference between two, or maybe I've missed something. I've experimented a little with InsertOrMerge, but all it does it replace the old data with the new data.

推荐答案

InsertOrUpdate =替换整个实体，包括删除新实体中未定义的任何字段.

InsertOrUpdate = replaces the entire entity, including removing any fields that were not defined in the new entity.

InsertOrMerge =如果新实体不包含旧字段和值，则旧字段和值将保留，并且所有其他字段将被更新.

InsertOrMerge = The old fields and values remain if the new entity does not include them, and all the other fields will be updated.
