And thanks everyone for your help. For us not so experience in Perl,
getting positive feedback seems to drive me to continue learning and
hopefully become more proficient.

Subject: Getting MySQL table info in perl script
Message-Id: <1194107177.955585.199080@o38g2000hse.googlegroups.com>
..ie the column name, definitions (varchar(100) etc). The most
obvious way is to parse the output from describe table_name. Is there
an easier way? My goal is to create a generic INSERT sub, which takes
as args table_name and a hash reference, eg:
$table_name = "TheTable";
$hash(Int1) = 99;
$hash(Float2) = 1.54;
$hash(String7) = "Goodbye cruel world";
..where Float2, Int1, String7 are some but not all cols in mysql table
TheTable. The sub is invoked as follows:
DoInsert($table_name, \%hash);
DoInsert will generate and execute the INSERT statement, NULLing out
fields not in %hash, single quoting string fields, etc., maybe even
doing data tyep compatibility tests. I would be happy to learn that
some one has beaten me to it, and a procedure like DoInsert already
exists.

I would suggest you ask in a NG that actually deals with Apache and web
servers. Chances are people there know much more about Apache than here.

I think you could adapt the technique described in
<http://www.stonehenge.com/merlyn/LinuxMag/col39.html> instead. That
is, fork a process to do the actual job.

I've heard rumors that it sends a TERM; followed shortly after by an
untrappable KILL, if necessary.
Fork and have the child do the work. If the parent gets killed the child
will probably continue. (For unix-like OSes)

This is a problem. My script must run on *nix and Win OS too. On both are
Appache running, but on Win platform fork not work correctly (here is
emulated only). Above this my script is a "fat boy" ;-) and if I know right
the fork create a copy of script, right?

Note that you can't handle SIGKILL (that's the point).

Put the bulk of the work in a separate script and run it with
system(1, ...) (see FUNCTION IMPLEMENTATIONS/system in perlport) or
Win32::Process.

Under Unix, not in any meaningful sense. The copy starts out sharing
everything with its parent, and only things that you modify are copied.

Lessons learned:
if you can't get into a perl shell from perl -MCPAN it may be from
the .cpan/CPAN.pm file. So you may not need to reinstall perl
The question I have is -- what commands are there to test a perl
configuration as appose to test a perl -MCPAN -e shell problem?
Anyone have a link to address this?
Well thanks everyone.

There is no such thing. You need root privileges if you're installing
modules in a directory for which such privs are needed - but that has
nothing at all to do with CPAN.

On my UNIX Server, perl 5.8.0 in installed. When I enter command:
perl -X -U plbsed.pl
I get following error:
Weak references are not implemented in the version of perl at /tmp/
replacebinary/Getopt/LL/DLList/Node.pm line 11
BEGIN failed--compilation aborted at /tmp/replacebinary/Getopt/LL/
DLList/Node.pm line 11.
Compilation failed in require at /tmp/replacebinary/Getopt/LL/
DLList.pm line 11.
I do not know how to suppress this error despite reaidng many artcles
on google.

You need to install the XS version of Scalar::Util. Make sure you have a
compiler installed, and that it is the one used to build your perl (if
it isn't, you will need to rebuild perl with this compiler), and then
reinstall Scalar::Util from CPAN.
