Count datetime entries for each month from datetime column in SQL Server -

i have table timestamps , want count total number of timestamps each month. have following script returning results. there simpler way this? select substring(convert(varchar(12), dt_create, 112), 0, 7) month, count(substring(convert(varchar(12), dt_create, 112), 0, 7)) signups table_name group substring(convert(varchar(12), dt_create, 112), 0, 7) order 1 output month signups ---------------- 201705 5959 201706 9782 201707 13663 201708 7385 characters values slower, may see increase in performance trying this. select year = year( dt_create ), month = month( dt_create ), signups = count( dt_create ) table_name group year( dt_create ), month( dt_create ) ;

python - What is the complexity of this recursive algorithm? -

does following algorithm have complexity of o(nlogn)? the thing confuses me algorithm divides twice, not once regular o(nlogn) algorithm, , each time o(n) work. def equivalent(a, b): if isequal(a, b): return true half = int(len(a) / 2) if 2*half != len(a): return false if (equivalent(a[:half], b[:half]) , equivalent(a[half:], b[half:])): return true if (equivalent(a[:half], b[half:]) , equivalent(a[half:], b[:half])): return true return false each of 4 recursive calls equivalent reduces amount of input data factor of 2. thus, assuming a , b have same length, , isequal has linear time complexity, can construct recurrence relation overall complexity: where c constant. can solve relation repeatedly substituting , spotting pattern: what upper limit of summation, m ? stopping condition occurs when len(a) odd . may anywhere between n , 1 , depending on prime decomposition of n . in worse case scena

c# - What do the square brackets mean, when it is after a string, and not an array? -

what square brackets mean, when after string, , not array? (e.g. str[5] in following example) string str; console.write("input string : "); str = console.readline(); console.writeline( (str.length < 6 && str.equals("hello")) || (str.startswith("hello") && str[5] == ' ') ); same thing means anywhere else. string is array (or @ least has indexer)... of char s. for example, have string: var x = "hello, cruel world." then can index char : var y = x[1]; at point y character 'e' .

clojure - Execute a vector of functions doesn't work when fns are passes as params -

this code doesn't work indended: (((fn [& fns] (fn [& params] (reduce #(%2 %1) params fns))) rest reverse) [1 2 3 4]) ;; => () instead of (3 2 1) is there way fix change inside #(%2 %1) ? i think question equivalent to: how convert (#<core$rest>) (rest) ? note: process solve http://www.4clojure.com/problem/58 i've seen other solutions curious specific implementation. try using [params] rather [& params] , so: (fn [params] (reduce #(%2 %1) params fns)) the [& params] argument taking collection [1 2 3 4] , wrapping again, in list , giving ([1 2 3 4]) seed reduce function. if wanted change inside #(%2 %1) need unwrap ([1 2 3 4]) , first time. see if first returned collection, (coll? (first %1)) , , call (first %1) , otherwise leave %1 is. seems convoluted , won't work other input data though.

How can I tell gradle-ssh-plugin not to prepend identifier to beginning of output lines? -

Image
i'm using gradle-ssh-plugin execute gradle scripts me on remote host (amazon-linux server running in aws). my gradle script looks like: remotes{ bastion { host = 'bastion.example.com' user = "ec2-user" identity = file("${homedir}/.keypairs/bastion.pem") } } ssh.settings{ knownhosts = allowanyhosts } task sshtest{ dolast{ ssh.run{ session(remotes.bastion){ execute "./gradlew doterraformstuff" } } } } this works fine. here's view of output (the colors terraform tool, executable gradle script invoking): the issue have how plugin prepends bastion#12| each line. "12" number goes each execution (i assume it's kind of plugin state survives invocation because of gradle daemon architecture). the question is: i'd know if there's way tell gradle-ssh-plugin not prepend remote identifier output - i'd see output of commands without prefix stuff.

c++ - Is there a design patter that can deal with method call dependencies? -

my problem this: when design c++ class, in cases, methods can called after other methods have been called, or after data member has been prepared. i found quite hard deal when there data member dependencies not obvious, , class needs extended support more features , functionalities. error-prone. execution speed of code not important in case, code clarity/maintainability/sensibility more important. if method2 called after method1 class has state. want keep state consistent , methods change/use state should not damage state. so need incapsulation. incapsulation not how make field private , create setfield() method change state. right answer: object change state. if have setters every single field have unprotected object , control consistent state has leaked. in practice, re-desing code data set during previous steps only. in case don't worry checking "is data prepared?" each time method2 called. to avoid untimely calls there several approaches.
