Re: [BUG ?] sort/reverse or RegExp problem
Quoting Ken Williams [EMAIL PROTECTED]:
hmm, ok
so if i do one test that actually matches late in my string and later do a test
that would match earlier, the latter will never match ?
i didn't know that; to me it doesn't sound logical. to me i'm doing a complete
fresh test in the regexp so if i had a match in a previous regexp test it
shouldn't matter since the string doesn't change and even the pos() shouldn't
change because to me both are completely fresh
anyway, thats how it is ...

Hi Allan,
No bug; here's a simpler example that shows what's going on.
$str = one two;
if ($str =~ /one/g) { print Found one\n }
print pos(\$str): , pos($str), \n;
if ($str =~ /two/g) { print Found two\n }
print pos(\$str): , pos($str), \n;
$str = one two;
if ($str =~ /two/g) { print Found two\n }
print pos(\$str): , pos($str), \n;
if ($str =~ /one/g) { print Found one\n }
print pos(\$str): , pos($str), \n;

DBI /SQL Server question []
hi
rather OT i gather but maybe its a general case on all platforms/dbs
i have an annoying problem with sql server, maybe someone have encountered
something similar - it concerns special (danish) characters that im unable to
insert correctly in the db table (they seem to be escaped with an even stranger
char in the db)
if i print the words that i want to insert to a txtfile i can see that they are
correct at that point
this works:
--
my $word = 'hardcoded with special chars: æøå';
my $sql = insert into $table (word) values (?);
my $sth = $dbh-prepare( $sql );
$sth-execute($word);
this doesn't work:
-
foreach my $word (keys %hash) {
my $sql = insert into $table (word) values (?);
my $sth = $dbh-prepare( $sql );
$sth-execute($word);
print OUT $sql ($word)\n; # looks correct
}
sort/order by [perl or possibly postgres]
hi
using a postgres db i have run into a sort order problem because i need to
order by a varchar type field/column.
im not aware of any function in postgres that might order the result
set correctly beforehand so i guess i want to post-sort the result-set with
perl.
i'm looking for something pretty effecient as the datastructure could be
potentially big
[
so in the end i need this order:
1
2
3
9
10
11
11a
11b
110
]
i have got the following sql syntax and datastructure
# sql, and data structure
$sth = $dbh-prepare( SELECT id, name, team_no from DB order by team_no ); #
etc.
$sth-execute();
$sth-bind_columns( undef, \$id, \$name, \$team_no);
while ( $sth-fetch ) {
$tied_hash{$team_no} = [$id, $name];
}
...
using tied_hash would currently sort something like this:
1
10
11
110
11a
11b
2
3
9
any suggestions most welcome
thanks

getting $1, $2 etc. in evaled regexp
hi
perl question
eh, is not possible to get the values in parens when you do a reg match on an
evaled string ?
consider the snippt below, how do i get the values into $1, $2 etc ...
my $str = /(.{11})(.{10})/i;
my $line = test string etc etc test string;
if ($line =~ eval(/ . $str . /)) {
print id = $1\n;
print pw = $2\n;
}

Re: getting $1, $2 etc. in evaled regexp
of course, you are right!
./allan
Quoting Michael P. Wilson [EMAIL PROTECTED]:
Allan,
I'm pretty sure you don't have to go through the eval to do what you're
trying to do. Can't you just build the regex straight like that, with
the $str?
if ($line =~ /$str/)
{...}
or am I just imagining things because it's 3:30 in the morning?

You'll need to find someone with the proper 'head' binary (much easier than finding the source and compiling it yourself) and have them mail it to you as an attachment or whatever. Then move 'HEAD' into /usr/local/bin/ (along with GET and POST and a few lwp-* programs), and put the real 'head' into /usr/bin/.

Re: installing Msql-Mysql-modules-1.2216.tar.gz
I have posted complete instructions for installing DBI::mysql under Mac OS X at http://duke.usask.ca/~dalglb/macosx/ thanks - i did manage to install it, however, about 91% of the tests still fail. these are mainly a problem with connecting to the mysql server, which is definetly running and visible in the processlist of the shell-inspector. my best guess is that it must have to with permissions somehow, but then again if im sudo'ing the make test, shouldnt i have access to everything more or less? another thing: when i try to rebuild the Msql-Mysql module i now dont get the prompt for a host, username and password - why is that? (when running the tests i can see it says using password:YES - does this litteraly means a password called YES or does it mean yes im using the password you entered somewhere when you initially build me?) in fact is it possible to do a clean install of this (or any module) that removes the old files? thanks once again -e allan

apache started (test page/cgi needed)
hello. i posted a queston regarding getting apache started/installed properly on OSX. thanks for all the replies! i did in fact get the server up and running and even got the apache test-page shown in internet explorer on the 127.0.0.1 addres then i wanted to test some simple cgi-scripts ... (which is the vague perl-relation to all this) 1) i guess i have to configure the httpd.conf file to accept cgi-programs in any directory, but even if i dont, how can i get a simple hello world in my browser? since then i have apparently messed too much about because now i have this strange problem: i can re-install apache from scratch, make a configtest syntactically ok, and do the usr/sbin/apachect1 start, restart or stop from the command line but im not able to hit any page from my browser window. so my question probably is: 2) can i properly uninstall apache (including old files like the httpd.file) and start afresh, or should i look elsewhere? any pointers appriciated. thanks allan
