Note that MySQL does not fully implement SQL standards, see
http://www.mysql.com/documentation/mysql/bychapter/manual_Compatibility.html#Compatibility
I don't know about Postgresql.
MySQL also had some security issues in the near past.

Thanks a lot to all of you for your valuable responses.
I have a clearer vision of the problem now.
Thanks again.

Hi,
I am trying to understand how a signal can received by a process.
I think I've mostly understood everything about the sending
step, but after send_sig_info() did a sigaddset and put
p->sigpending = 1 (p is a pointer to the target task_struct)
how the kernel now that a signal has arrived on the target process ?
What is the link with the ret_from_intr() and do_signal functions ??
Thanks if you can help me.

You may find some basic-to-something converters around. I'm sure I
remember a `bastoc' and there's a VisualBasic to C/GTK converter (V0.02 !)

Subject: Stupid shell question:
Date: Fri, 09 Apr 1999 14:12:53 -0400
Ok, I feel like an idiot for asking but my shell experience is still
somewhat limited and I haven't had much time in the shell recently, so I
thought I'd ask:
How do I phrase a command such that the command is actually spawned into
another shell, creating an entirely new window in an XWindows session?
For some reason it seemed like it was simple like ending with a '&' but
there must be more to it. I'm using the BASH shell.
Also, along these same lines, I use the Cygnus GNU compatibility toolkit
under my Windows toolkit. Using the BASH that came with it, is this
something that is even possible? I've written a little batch file that
launches cmd -c under NT and will run "start" to pass it the parameters
so as to have this effect. It just seems like there would be a better
way to do this the same as under Unix. I will be putting Linux back on
my home box soon and I wanted to remember how to do this since I tend to
use shells, makes and VI as my development environment.
Thanks!

Subject: profiling a dynamic library
Date: Fri, 09 Apr 1999 19:37:30 +0200
Hi,
I profile my programs (prof or gprof )
And before now i have no problem.
Now,
I've wrote a dynamic library ( .so ) that I link at the complilation
step to my main
program.
gcc myprog -o a.out -lmylib
BUT : gprof see symbols only in the main program ( a.out )
and give no statistics about the functions of the library.
Do anybody know the option ( of gprof or gcc ) for watch the symbols
of a liked library
Thanks .

OK, thanks. I guess MS and Borland have a different idea of processor
time and interpret it as elapsed time.

If my return address contains "ZAP." please remove it. Sorry for the
