如何用NHibernate和Fluent NHibernate存储一个非截断的varchar（max）字符串 [英] How to store a non truncated varchar(max) string with NHibernate and Fluent NHibernate

问题描述

我的数据库模式有一个字符串作为varchar（max）。我已阅读其他问题有关设置长度超过4000或8000，以便它真的在映射中生成（n）varchar（max），但是当我在映射类中使用Length（10000）时，hbm文件实际上显示length =10000我保存超过10000个字符的实体，它实际上被截断为10000个字符。

我不希望有任何截断。

（使用NH3-alpha2和FNH干线）

解决方案

看起来这是一个老问题现在在NHibernate 3.x版本中重铺;您可以阅读有关变通办法此处 。

$ b 注意：我更新了过期的原贴。

My DB schema has a string as a varchar(max). I have read the other questions concerning setting Length to more than 4000 or 8000 so that it really generates a (n)varchar(max) in the mapping but when I use Length(10000) in my mapping class, the hbm file actually shows length="10000" and if I save an entity with more than 10000 chars, it is actually truncated to exactly 10000 chars.

I don't want any truncation.

(using NH3-alpha2 and FNH trunk)

解决方案

It would appear that this is an old problem which is now resurfacing in NHibernate 3.x builds; you can read about the workarounds here.
