database - Does stored procedure help eliminates SQL injection / What are the benefits of stored procedured over normal SQL statement in apps? -

-

I am very new in SQL world Here are my questions:

  • Applications include the usual SQL What are the benefits of the above stored procedures?
  • Does Archived Process Assistance End SQL Injection?
  • In Microsoft SQL Server it is called stored procedure. How about Oracle, MySQL, DB2 etc?

Thank you for your explanation.

The stored procedures should only prevent directly SQL injection if you want them If you still have the name of the process with your app, and you have consolidated criteria of that string in your code from user input, you still have trouble.

However, when < Em> Exclusively, you add some additional security to the stored procedure This can make it possible for you to disable permissions for all but EXEC orders In addition, the query / prepared statements with parameters are usually cached by the server, and in almost every case, just like a stored procedure Are there.

Despite this, there are two major advantages for large enterprises of stored procedures:

  • They allow you to define an application interface for the database, so that In those applications the system is shared among many applications without duplicating the reasoning.
  • They transfer SQL to DB, where you can easily maintain an experienced DBA tune, update, and otherwise retain it, instead the application developers

Of course These advantages are of no cost:

  • It is difficult
  • code is separated from code
  • Several stored procedures Developer tools for management are less than ideal (if you are ever open database lost 200 processes Stored in the Management Studio Procedures folder, I am talking to you know what I talking about here).

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...
