mysql - How to count and group items by day of the week? -

-

i have following (mysql) table called "tweets": 

tweet_id   created_at --------------------- 1          1298027046 2          1298027100 5          1298477008

i want mysql returning number of tweets per day of week; taking above data should return:

wednesday 1 friday    2

i have following query (which should return day of week index, not full name):

select    count(`tweet_id`),   weekday(from_unixtime(`created_at`)) tweets2  order weekday(from_unixtime(`created_at`))

this returns:

count(`tweet_id`)   weekday(from_unixtime(`created_at`)) 7377                4

(there total of 7377 tweets in database). doing wrong?

select  count(`tweet_id`), dayname(from_unixtime(created_at)) day_name1 tweets2   group day_name1 order day_name1;

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.
