sql - SELECT count(*) then output empty or not empty with yes or no -


Find out if the location of the sales department is in cities similar to that of the TRANSPORT department "(assuming the empty result means yes and No non-fair result is the meaning)

This table was found in my database. 

  // DEPTLOC DAME CITY ---------- ------ Sales London Transport London Transport Boston Science Boston   
 Definitely how to write queries but at least I try  
  SELECT COUNT (*) DEPTLO How to write after AND operator in SKL in order to get something out of the output (DNAME = 'SALES' and DNAME = 'TRANSPORT') and   
 C WHERE  
  // Display Yes. (& Lt; --- London, sales and transport in the same city)    
 
 
 You can use   SELECT Decode (Count (*), 0, 'No', 'Yes') from your remaining question}   
  DECODE  compares each search value with one. If the expr is equal to one search, then the Oracle database gives the same result. If no mail is found, then Oracle default comes back. If the default is omitted, then the oracle is empty.

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...
