nhibernate - Invalid index n for this SqlParameterCollection with Count=m -

-

i'm getting nasty error in castle active record (wrapped around nhibernate) when try save class:

invalid index n sqlparametercollection count=m

i know error caused property being mapped multiple times in class i'm not sure how around it. have 2 child classes both map class in question using same column (ipaddressnumber). ipaddressnumber primary key of class, results in nhibernate trying map ipaddressnumber property 3 times (just guess.)

here class:

[activerecord(lazy=true)]     public class deviceconfiguration : usersdatabase<deviceconfiguration>     {         [primarykey]         public virtual long ipaddressnumber { get; set; }          [belongsto("ipaddressnumber", lazy = fetchwhen.oninvoke)]         public virtual vehicle vehicle { get; set; }          [belongsto("ipaddressnumber", lazy = fetchwhen.oninvoke)]         public virtual jbusconfiguration jbusconfiguration { get; set; } }

any appreciated...

i ended having remove second association altogether around issue. not great solution 1 find.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
