sql - mysql select query - to match one field with the other field -

-

i trying find records has following scenario.

id |     name   |      email  1      robert        robert@gmail.com  2      william       bill@gmail.com  3      michael       michael@gmail.com  4      micahel       mike@gmail.com

based on above table, want find records "name" contained in "email field", here record 1 , 3 should output , not 2 , 4. there way can comparison?

i tried reading regex couldn't find anything. if it's comparison of same value, straightforward, not having clue one. thought of like looks cannot have field names.

the exact syntax depend on how want define relationship.

are looking name anywhere in email address? (this slow)

select id,name,email your_table email concat('%',name,'%')

just @ beginning of email address?

select id,name,email your_table email concat(name,'%')

just before @ sign?

select id,name,email your_table email concat(name,'@%')

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.
