pivot with two columns combine ms sql -


I want to see results that display in pivot mode in table mode. Although column names for other rows are a combination of Person_Id and Author_Number, and the value for that column should be Project_Id to make it easy to understand, please see sample results below: 

  client_id 12345_1 12345_2 12346_1 12346_2 12346_1 Client 1 Test 1 Test 1 Client 2 Test 2 Test 2 Client 3 Test 3   
 Note that the combination of Person_Id and Author_Number from the second column and so on is further ahead.  
 Here is the sample table  
  CREATE TABLE [dbo]. [Names]] [Names]] [Names]] [Family name] [Navvorkar] (50) [Navarachar] (50) No tap, [Project_ID] [Navvorkar] (50) No, zero, [ Include in the values ​​('Client 1', 'Test 1', 12345,1), the author (customer ID, project_id, person_id, author_number, family_name, first_name), person_ID] [first_name] [navelist] (50) 'Gist', 'Fede' writers (client_id, project_id, person_id, author_number, family_name, first_name) Enter values ​​('Customer1', 'TEET1', 12345,2, 'Ma', 'K') in the authors (Client_ID, Project_ID, Person_ID, Author_Number, Family_Name, First_Name) VALUES ('Client2', 'TEST2 Include in values ​​('Client 2', 'Test 2', 12346,2, 'Davis',' 12346, 1, 'Jones',' Peter ') in the author (client_id, project_id, person_id, author_number, family_name, first_name) , 'Bob') INSERT authors (client_id, project_id, person_id, author_number, family name, first_name) mu ('Client 3', 'Test 3', 12346,3, 'Richards', 'Craig')   
 This is the script  
  DECLARE @ ColsPivot AS NVARCHAR (MAX), @class AS NVARCHAR (maximum) select @colsPivot = STUFF (SELECT ',' + QUOTENAME (c.col + '_' + cast), type (APIDPP (''), type). Price ('.', 'NVHAR (Max)'), 1,1, '') set @query = 'Select client_id,' + @ colsPivot + '(select Client_id, col +' '_' '+ cast ( X1 fumes (maximum) for the colon in val (select client_id ('+ + + colspivot +'), call 'varchar' (10)) as the author, print 'quality @ exec' (@query)  / Pre> 
 I do not know what the problem with the script is that the value displayed after the client ID column is   
 
 
 Try this query I have to update it Is selected.  
  DECLARE @ colsPivot AS NVARCHAR (MAX), @ class AS select NVARCHAR (MAX) @colsPivot = STUFF ((SELECT ',' + QUOTENAME (c.col + '_ 'CD (VARCHAR (10)) as the person in the form of VERSAR (C) for XML path (' ', type)' value '('. ',' NVARCHAR () '(author,' varchar (10)) ), '1,1', '' set @query = 'select Client_ID,' + @ colsPivot + '(select Client_ID, cast (varchar (10) as personality)' '_' ' + Cast (Author_Number as Varchar (10)) From Call, Val (Select Client_id, Project_id, Person_Id, Author_Number, Family_Name, First_name from author) in Unpivot (Colonel's) A) Valid (P) (P) (printed by @Police_id)) Pvot (max (+ valcolate + @colspivot + ')) P Print' QuickEx (@ Korea)   
 and the output of the above query is: / p> 
  Client_id 12345_1 12345_2 12346_1 12346_2 12346_3 ----------------------------------- ------------- ---------- Client 1 Test 1 Test 1 Nail Nail Client 2 Nail Faucet Test 2 Test 2 Faucet Client 3 Nail Nail Nell Nell Test 3 < / code>

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...
