asp.net - SQL count all of the column that has a value greater than 10 and sum it up -


I want to count all the columns in my table, which has the value & gt; = 10. Here is my table:

Date ##### || Value1 || Value2 || Value 3

23/04/2014 || __ 1,2 || __ 12,3 || __10 ||

23/04/2014 || __ 11,2 || ____ 3 || __10,3 ||

24/04/2014 || __10 9 || ____ 3 || __ 1 ||

I want to display it:

Date ##### || Calculation ||

23/04/2014 || __ 4 ||

24/04/2014 || __ 1 ||

Let's say I have a lot of time, I want to display this only the last 3 rows.

This is my first code:

count (*)> = 10 group from tbount to date as tcount Select the count (*); Based on the solution from collapsar it has been changed: 

  String = as the slow stromm = "select td, sum (t.valcount) cnt From (select [date] as d, case when t1.ManualAssists1 & Gt; = 10 THEN 1 ELSE 0 END + case when t1.ManualAssists2> = 10 THEN 1 ELSE 0 END + case when t1.ManualAssists3> = 10 THEN TD "by T / TT Group Group TBBooth T1 as 1 ELSE 0 END"   
 This works , But I only want to display the last 3 lines based on the ASC order. How to do it anyway?  
 Thanks in advance ....   
 < Div class = "post-text" itemprop = "text"> 
 Try  
  select td, sum (t.valcount) from cnt (select [date] as d, case when t1.value1> = 10 THEN 1 ELSE 0 END + case when t1 value2> = 10 THEN 1 ELSE 0 END + case when t1.value3 & gt; = 10 THEN 1 ELSE 0 END as Table T / T by Group T) Group T;

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...
