MySQL create function won't return sets -

-

I can not get this work done with MySQL 5.x This function should return all the relevant rows to the selection-statement: 

  create build getuids (root INT) Set as INT $ $ INST Select Return Date WHERE removed from pages = 0 END $$ language 'SQL';

Any thoughts that I have done wrong?

A MySQL function can not return a set of lines or rows in MySQL to only one stored procedure rows Can return This is true for MySQL 5.4 and the use of stored procedures in the form of page view tables or where segment values ​​in the questions are also unavailable.

If you want to use a function, you can do the best so that GROUP_CONCAT can be used to get values ​​in comma separated list:

Create getuids function () Return VARCHAR (1024) Select Start GROUP_CONCAT (UID SEPARATOR ',') IU.Out_list pages of WHERE Destroy = 0; Return @uid_list; END

Then you need to check the UIDs in your selection statement, you can use the FIND_IN_SET function like this: 

  SELECT. .. WHERE FIND_IN_SET (My_field, get_uids ());

PS I originally posted links on the GROUP_CONCAT and FIND_IN_SET functions on MySQL website, but Stack Overflow will only allow me to use a link to be new.

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...
