arangodb - AQL aggregation functions syntax -


What is the syntax for parallel functions such as (sentence)?

For example, do the following: 

  let's go to json = {"age": {"age": ["20", "30", "40" ]}}   
 and  json.ages.age return age   
 returns  
  ["20 "In all these snippets the return on" [1542] invalid logic type was used for "In Age  
 " 30 "," 40 "]   
 Which has been used to call for 'SIM (")" Ango 2.0.4:  
  // age of LR age = (json.ages.age Return age at age For) Amount Refund (age) / LR age R = (json.ages.age return age for age) return amount (for ages at the age of json.ages.age return)) //R return amount ((json.ages.age return age at age) For))   
 What is correct syntax?  
 No related examples appear in the syntax page ().  
 Most of the thing is that I can get a syntax for example:  
  controller.get ("/ revenue /: year", function (rick, Ridge) {var query = "return Sam (bill collection fitter bill for bill. Yure == @ year return bill.mount))"; var stmt = db._createStatement ({"query": query}); stmt.bind ("year", parseInt (req.params ("year"), 10)); Var c = stmt.execute (); Res.json (c); });   
 But it seems that the syntax above has failed for me.  
 Is there any more detailed syntax references anywhere?

 Your approach is correct, though you have a small Miss the place. ;)  
 In the document for SOM it says:  
 
 SUM (list): returns the sum of the values ​​in the list to be the number of elements in this list Required   
 (Docs Reference :)  
 Note  "Elements in this list need to be number"   
 Therefore, instead of the stars in your JSON-example, there should be a number in the list.  
  let's json = {"ages": {"age": [20, 30, 40]}} age = (json.ages.age return age at age) return amount ( Age)   
 The snippet above should be copied and run in your AUKD editor:    [9 0]   < p> You can also leave your JSN intact and change the number of stars by changing the AULL query to:

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
