SQL - Do you have to repeat ORDER BY in outer query? -


i have query:

select   t1.*     t1 order t1.date

this query in enclosed in query:

select * (select   t1.*                    t1                order t1.date) t2

do have repeat order by in outer query? this:

select * (select   t1.*                    t1                order t1.date) t2 order t2.date

does answer change if inner query moved cte?

yes ,you have repeat order in outer query,if want output ordered.

sqlserver honours order in outer query , inner order meaningless

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
