MySQL average of non-null columns -

-
i've kludged way through doing this, feel there's cleaner/faster/better solution, , keen learn: update mytable set favg = (coalesce(f1,0) + coalesce(f2,0) + coalesce(f3,0) + coalesce(f4,0)) / ( case when f1 not null 1 else 0 end + case when f2 not null 1 else 0 end + case when f3 not null 1 else 0 end + case when f4 not null 1 else 0 end ) so, how can improved? you can simplify count taking advantage of fact mysql treats booleans integers in numeric context: update mytable set favg = (coalesce(f1,0) + coalesce(f2,0) + coalesce(f3,0) + coalesce(f4,0)) / ((f1 not null) + (f2 not null) + (f3 not null) + (f4 not null));

i went through lot of readings mvc , each of these more or less clear. haven't understood yet how relate. mean, know these relationships but how implemented? happens in mvc framework? i have few questions: i read a view can't coupled controller , in other words can't have controller object inside, how use proper controller if view supposed trigger in it? how can model update view if unique job represent data? is business logic inside controller or model? have read conflicting points of view the basic explination of mvc have each of 3 layers. model this contains data. i.e database or set of classes. view this displays data user i.e html page. contains controls user interaction. controller all access data should go through layer. i.e load data data source(model) , save data data source. carries out data manipulation before saving or loading. this create separation of concerns theoretically allowing change in either layer without

Android AsyncTask called "multiple" times -

-
i'm new android programming. have main activity gets data db through service handler (url). want insert data well, on different activity, , want main activity date each time been called (onresume(),onrestart()). i've found on android api reference asynctask: the task can executed once (an exception thrown if second execution attempted.) mean cannot call asynctask whenever activity resumes, or cannot have multiple "instances" of asynctask running @ same time? it literally means, while asynctask running, cannot launch again. in mainactivity.class have line: task.execute(); if task either finished or not , call method again exception thrown. and put method in onresume () practice. 1 thing notice is: if put in onrestart () remember, callback works when change configuration, not called if create activity . the doc lifecycle of activity .
