how can change sql return default value if no rows found? eg: select text,name text_file text='met' if no rows found, text contain 'values not found' example one method uses union all : select text, name text_file text = 'met' union select max('values not found'), null text_file text = 'met' having count(*) = 0; notes. second subquery aggregation query. returns 1 row (without having ). row has looking for. second, type of operation should done in application , not database. third, if expecting 1 row, can use aggregation query such as: select (case when count(*) > 0 text else 'values not found' end) text, (case when count(*) > 0 name end) name text_file text = 'met'

i started playing algorithms this princeton course , observed following pattern o(n) double max = a[0]; (int = 1; < n; i++) if (a[i] > max) max = a[i]; o(n^2) for (int = 0; < n; i++) (int j = i+1; j < n; j++) if (a[i] + a[j] == 0) cnt++; o(n^3) for (int = 0; < n; i++) (int j = i+1; j < n; j++) (int k = j+1; k < n; k++) if (a[i] + a[j] + a[k] == 0) cnt++; the common pattern here nesting in loop grows exponent increases. safe assume if have 20-for loops complexity 0(n^20)? ps: note 20 random number picked, , yes if nest 20 loops in code there wrong you. it depends on loops do. example, if change end of 2nd loop 3 iterations this: for (int = 0; < n; i++) (int j = i; j < i+3; j++) if (a[i] + a[j] == 0) cnt++; we o(n) the key whether number of iterations in loop related n , increases linearly n does. here example 2nd loop goes n ^ 2: for (i...

i playing around in java 8. how can return method reference? i able return lambda not method reference. my attempts: public supplier<?> foreachchild(){ return new arraylist<?>::foreach; } or public function<?> foreachchild(){ return new arraylist<?>::foreach; } you have small mis-understanding of how method-references work. first of all, cannot new method-reference. then, let's reason through want do. want method foreachchild able return accept list , consumer . list on object invoke foreach on, , consumer action perform on each element of list. that, can use biconsumer : represents operation taking 2 parameters , returning no results: first parameter list , second parameter consumer. as such, following work: public <t> biconsumer<list<t>, consumer<? super t>> foreachchild() { return list::foreach; } this type of method-reference called "reference instance method of arbitrary ...

following image shows design 2 uiview. 1 in green should 20% , yellow should 80%, in land scape or portrait. i missing on constraint or content hugging change, trying fix. note: content hugging , compression priority has default values. you don't want have fixed height of 212 top view. want 20% of it's super view. you should delete top view's height constraint of 212. select both top view , super view. add equal height constraint. double click on constraint , open it's size inspector. change multiplier 0.2
