防止Nhibernate schemaexport生成外键约束有很多关系 [英] Prevent Nhibernate schemaexport from generating foreign key constraints on has many relationship
本文介绍了防止Nhibernate schemaexport生成外键约束有很多关系的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有这样的映射:
$ b $ pre $ HasMany(x => x.Orders).KeyColumn(CustomerID );
这是由schemaexport产生的一个约束:
alter table [CustomerOrder]
添加约束FK45B3FB85AF01218D
外键(CustomerID)
引用[Customer]
我曾尝试添加.NotFound.Ignore()像一个References()映射来禁用生成的约束,但是这不起作用。
可以定义一个映射来强制SchemaExport不生成约束吗?
解决方案 (b)
$ b
$ b
HasMany(x => x.Orders).KeyColumn(CustomerID) .ForeignKeyConstraintName( 无);埋在源文件中的
如果名称为none,则忽略创建检查
I have a mapping like this:
HasMany(x => x.Orders).KeyColumn("CustomerID");
Which is causing a constraint like this to be generated by schemaexport:
alter table [CustomerOrder]
add constraint FK45B3FB85AF01218D
foreign key (CustomerID)
references [Customer]
I have tried adding .NotFound.Ignore() like on a References() mapping to disable the constraint from being generated but this does not work.
Can a mapping be defined that will force SchemaExport to not generate the constraint?
解决方案
Figured it out:
HasMany(x => x.Orders).KeyColumn("CustomerID").ForeignKeyConstraintName("none");
buried in the source is a check to ignore creation if the name is "none"
