c# - Logging changes using LINQ to SQL -

-

in system creating, customer requires changes data logged database table - changes being logged (i.e. if change 1 value on form full of 10 fields, it'll audit 1 change). need able compare old values new values.

this of course easy - i've done before, rather messy - manually check each field in database , compare new 1 decide if should audited. there easier way, of perhaps automatically getting changed column name/values? or have 'messy' way?

pretty of changes logged done using linq sql - perhaps there's way compare database table modified one, before calling submit changes?

i used article on code project titled automatic event logging in linq. worked us, requested, far logging changes. if record inserted each update appears seperate row in database tracking pk, field name, old value, , new value. of course tracks performed action , when. tracks actions: create, read, update , delete.

this method satisfies request dynamically include of tables, no seperate method each table.

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.
