you could use a cursor: DECLARE @id int DECLARE @pass varchar(100) DECLARE cur CURSOR FOR SELECT Id, Password FROM @temp OPEN cur FETCH NEXT FROM cur INTO @id, @pass WHILE @@FETCH_STATUS = 0 BEGIN EXEC mysp @id, @pass … — call your sp here FETCH NEXT FROM cur INTO @id, @pass END CLOSE cur DEALLOCATE … Read more
Lets see why JavaScript behaves like this. According to the ECMAScript standard specification for Array.prototype.forEach, when you delete an element at index 1, the element at index 2 becomes the element at index 1 and index 2 doesn’t exist for that object. Now, JavaScript looks for element 2 in the object, which is not found, … Read more
I found another approach: foreach (var car in cars) if (!rentedCars.Contains(car)) { // Magic }
What you want to achieve is totally possible with Array#forEach — although in a different way you might think of it. You can not do a thing like this: var array = [‘some’, ‘array’, ‘containing’, ‘words’]; array.forEach(function (el) { console.log(el); wait(1000); // wait 1000 milliseconds }); console.log(‘Loop finished.’); … and get the output: some array … Read more
Look at how the for-each loop internally works, see How does the Java ‘for each’ loop work? for(Iterator<String> i = someList.iterator(); i.hasNext(); ) { String item = i.next(); System.out.println(item); } Each time it declares the String variable item. Hence in your case its doing essentially State state; \\and inside State state = i.next(); which obviously … Read more
I would use a Map myself. But taking you at your word that a pair of arrays makes sense in your case, how about a utility method that takes your two arrays and returns an Iterable wrapper? Conceptually: for (Pair<K,V> p : wrap(list1, list2)) { doStuff(p.getKey()); doStuff(p.getValue()); } The Iterable<Pair<K,V>> wrapper would hide the bounds … Read more
You could, of course, “make the outer value mutable” via a trick: public void test() { String[] x = new String[1]; List<String> list = Arrays.asList(“a”, “b”, “c”, “d”); list.forEach(n -> { if (n.equals(“d”)) x[0] = “match the value”; }); } Get ready for a beating by the functional purist on the team, though. Much nicer, … Read more
use a comprehension for d, i in flights console.log d, i The code above translates to var d, i, _i, _len; for (i = _i = 0, _len = flights.length; _i < _len; i = ++_i) { d = flights[i]; console.log(d, i); } so you can see d and i are what you want them … Read more
it is just a default param name inside of all single argument closures. You could specify param name by yourself: collection.forEach { customName -> … }
