  एक का चयन करें, अंतिम_नोट_यूसर, c, d, iso_src एक्स क्रॉस से जुड़ें वाई क्रॉस जॉइन जेड वाम ओएटर में शामिल हों उपरोक्त एएनएसआई कोड मुझे 107 रिकॉर्ड प्राप्त करता है, जब मैं एएनएसआई कोड के बिना एक ही प्रश्न दे रहा हूं तो यह 875 रिकॉर्ड ला रहा है। गैर एएनएसआई क्वेरी नीचे है:  
  SELECT a, last_note_user, c, d, iso_src FROM एक्स, वाई, जेड, डब्ल्यू WHERE W.last_note_user = Z.userid (+) और W.user_ten = Y.iso_src (+)  
 
 एएनएसआई और एएनएसआई मानक के बिना दो प्रश्नों में अंतर क्यों है ?? उपरोक्त प्रश्न का उत्तर देकर कृपया मेरी मदद करें !!!

आपकी पुरानी-शैली की क्वेरी में (+ ) प्रतीकों के गलत पक्ष पर प्रतीकों यह होना चाहिए: 

  SELECT a, last_note_user, c, d, iso_src से एक्स, वाई, जेड, डब्ल्यू। डब्लू ._last_note_user (+) = Z.userid और W.user_ten (+) = Y.iso_src

लेकिन मैं पुरानी शैली के वाक्यविन्यास को वास्तव में किसी भी अधिक उपयोग नहीं करेगा।

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...

c - Linux mmap() error -

I have a memory map file, out of which I want to parse the content of the buffer. MMAP () achieves success, and I can successfully use fprintf to print the buffer content in the file. However, when I try to access Buffer as an array in my program directly, I get a partition error. Why is this happening? Here's the code: #define PTT_DUMP "/ home / druru / somefile". . Int fd_ptt_dump = Open (PTT_DUMP, O_RDONLY); Structure state struct_ptt_dump; Fstat (fd_ptt_dump, & amp; struct_ptt_dump); Printf ("\ n \ n \ t \ t \ t --- Size of dump =% d ----- \ n \ n", struct_ptt_dump.st_size); Four * membuffer; Four pid_num [100]; Four cycles [100], examples [100], CPI [100]; Int pid_index = 0; Int cycles_index = 0; Int instr_index = 0; Int cpi_index = 0; Int len ​​= (int) struct_ptt_dump.st_size; Int newline_count = 0; Int n = 0; If ((membuffer = mmap (0, struct_ptt_dump.st_size, PROT_READ, MAP_FILE | MAP_PRIVATE, fd_ptt_dump, 0)) == (caddr_t) -1) err_sys ("mm...
