MySQL - JOIN data from two columns into one output -


first time posting stack, apologies if screw up.

i have table of data in mysql i'll call table1. table has time stamps when transaction goes live, , when same transaction closed out. can run 2 separate queries (seen below) generate count amount transactions created per hour (query1), , amount of transactions resolved per hour (query2) - if combine queries, can data need starting @ hour 4 (when people begin work) need data transactions created before can create comprehensive output shows our total transactions incoming (starting @ hour 0) , showing how many we're completing (starting @ hour 4).

query1

select date_format(created_at, '%h') 'hour', count(distinct(created_at)) queued
from table1
where date_format(created_at, '%m-%d-%y') = '04-02-2017'
group date_format(created_at, '%h');

query2


select date_format(resolved_at, '%h') 'hour', count(distinct resolved_at) 'worked'
from table1
where date_format(resolved_at, '%m-%d-%y') = '04-02-2017'
group date_format(resolved_at, '%h');

if run query 3, pulls right data hours 4 - 23 (when we're staffed) can't hours 0-3

query3

select date_format(resolved_at, '%h') 'hour', count(distinct resolved_at) 'worked', count(distinct created_at) 'queued'
from table1
where date_format(resolved_at, '%m-%d-%y') = '04-02-2017'
group date_format(resolved_at, '%h');

thank you! tried post example of output, couldnt formatting right.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
