How do you count the rows in a SQL query which already used count, group by, and having before? -

-

for example, using answer question:

how select users made more 10 submissions "how select users made more 10 submissions."

select userid submission    group userid having count(submissionguid) > 10

let's want know many rows sql statement outputted. how scalable solution counting rows of counting rows?

slight error in posted example, need alias table name subquery:

 select count(*)   (select userid    submission     group userid    having count(submissionguid) > 10) t

i'm not sure scalability, solution. if isn't scaling enough you, need consider major design changes, perhaps tracking submitted more 10 submissions in separate table update through applications populate submissions. or many other possible solutions.

i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
