SQL Count(*) and Group By - Find Difference Between Rows -

-

Below is a SQL query that I wrote to find the total rows of each product ID (proc_id): 

  SELECT proc_id, proc (WHOLE) WHERE grouping_primary = 'SLB' and 'eff_date = '01 -JUL-09' by proc_id ORDER BY proc_id; Below is the result of the SQL query:  
 proc_id count (*) 01 626 02 624 03 626 04 624 05 622 06 624 07 624 09 624  
 How do I write an SQL query to know which proc_id lines are different for proc_id = '01', proc_id = '03', and proc_id = '05' compared to other proc_id? First of all, you need to define the criteria that '624' makes right this is the average code  
 
 
 > Count (*) ? Is it  count (*)  which is most often? Is this your favorite  count (*) ? 
 
 Then you can use the Housing Clause to separate the person who does not match your criteria: 
 
  SELECT proc_id, count (*) from proc WHERE grouping_primary = 'SLB' and eff_date = '01 -JUL-09 'by proc_id group Howing (*) & lt; & Gt; 624 Order BY proc_id; Select  
 
 or: 
 
  select proc_id, count (*) from Pro WHERE grouping_primary = 'SLB' and eff_date = '01 -JUL-09 ' Proc_id Hewing Calculation (*) by Group & lt; & Gt; (Insert a subquery here that creates magic '624' & gt; ORDER BY proc_id;

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
