sql - conditional ordering by two fields -


मेरे पास यह प्रश्न है: 

  SELECT * से राष्ट्रवादी एसोसिएशन के एस्सीसी, डीएफसीएए < / कोड>  
  NPENDIENTE  एक नकारात्मक या सकारात्मक नंबर हो सकता है। मैं चाहता हूं कि जब यह फ़ील्ड 0 से अधिक हो, इस ऑर्डर का उपयोग बंद हो जाता है और  ORFER BY DFECHA  लेता है।  
 मैं यह कैसे कर सकता हूं?   < p> 
 
 इसे ऐसा करना चाहिए:  <प्री>  SELECT * FROM PENDIENTESCOBRO ORDER द्वारा मामले में जब एनपीन्डेन्टए & gt; 0 तब 1 ELSE NPENDIENTE END ASC, DFECHA   
 ऐसा इसलिए है क्योंकि आप SQLite ORDER BY खंडों में केस एस्प्रेस का उपयोग कर सकते हैं। मैं जो केस डालता हूं वह सभी सकारात्मक (& gt; 0) एनपेंडेन्टिटी मानों का एक ही क्रम मान होता है ... इसलिए डीएफसीएए द्वारा पंक्तियों का आदेश दिया जाता है।

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. To clarify - this will not be a method error because it is a linked list.

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...
