You get a tick for each line ; and each block {} Try that: declare(ticks=1) echo ‘foo!bar’; No block, no extra tick. declare(ticks=1) {{ echo ‘foo!bar’; }} More extraneous blocks = more ticks. PS: by the way, ticks are quite the exotic feature and they’re only useful in a few extremely rare situations. They are … Read more
The global declaration is when you declare that times is global def timeit(): global times # <- global declaration # … If a variable is declared global, it can’t be used before the declaration. In this case, I don’t think you need the declaration at all, because you’re not assigning to times, just modifying it.
In Java 9+ you can do: var x = List.of(“xyz”, “abc”); // ‘var’ works only for local variables Java 8 using Stream: Stream.of(“xyz”, “abc”).collect(Collectors.toList()); And of course, you can create a new object using the constructor that accepts a Collection: List<String> x = new ArrayList<>(Arrays.asList(“xyz”, “abc”)); Tip: The docs contains very useful information that usually … Read more
Use array.push() to add an item to the end of the array. var sample = new Array(); sample.push(new Object()); To do this n times use a for loop. var n = 100; var sample = new Array(); for (var i = 0; i < n; i++) sample.push(new Object()); Note that you can also substitute new … Read more
I ran into this same issue, but I think I know what’s causing the confusion. If you use MySQL Query Analyzer, you can do this just fine: SELECT myvalue INTO @myvar FROM mytable WHERE anothervalue = 1; However, if you put that same query in MySQL Workbench, it will throw a syntax error. I don’t … Read more
A definition is where a value or function is described, i.e. the compiler or programmer is told precisely what it is, e.g. int foo() { return 1; } int var; // or, e.g. int var = 5; but this is clearer. A declaration tells the compiler, or programmer that the function or variable exists. e.g. … Read more
I explain this in my answer to Why was the C syntax for arrays, pointers, and functions designed this way?, and it basically comes down to: the language authors preferred to make the syntax variable-centric rather than type-centric. That is, they wanted a programmer to look at the declaration and think “if I write the … Read more
I am using the SQL-Developer in Version 3.2. The other stuff didn’t work for me, but this did: define value1 = ‘sysdate’ SELECT &&value1 from dual; Also it’s the slickest way presented here, yet. (If you omit the “define”-part you’ll be prompted for that value)
