  Re: perl dbi sybase number of columns?

The whole point of the DBI is to (and I quote) "provide a consistent
database interface, independent of the actual database being used."
Therefore it is entirely unimportant that you are querying a Sybase
database.

Isn't PHP great?

did you read the documentation for the module you're trying to use? or
did you think it would be easier to have us read it to you?

perldoc DBI

hint: pay particular attention to the section on "Statement Handle
Attributes"

  Google Custom Search Engine         


Author: robert.hundt

Hi,

I created a Google Custom Search Engine for searching on:

"Software / Compilers / Optimization"

This is basically a regular full Google search giving preference to
technical sites such as IEEE, ACM, citeseer, the Universities,
news-group (this one included), commercial sites such as Intel,
Microsoft, HP, Sun, IBM, and others. The search results are further
biased towards software development, programming languages, and
optimizing compilers

The results are indeed much more specific than the regular Google
search. Try ity out! Additionally, if you are interested, please send
me an email and you can contribute to this search engine and add sites
you believe should be given preference to. Over time, it should become
better and better...

I "donated" a no-nonsense URL: www.codeopt.com

Check it out - and let me know what you think (no rants, please)!

Cheers

You do realize you initially asked "How to I checkout files" not "How do
I call cleartool mkbranch" don't you?

  Date::Calc and postgres timestamp         


Author: jeff_jones_101
Date: Dec 27, 2006 06:50

Dear all,

I'd little a little hint on date comparison using Date::Cal module.

I take the first date from a postgres db where the field is declared
as:
created | timestamp(6) without time zone |
Selecting through DBI I receive a date in the form of
2006-12-14 16:08:39

The second one is a a Date::Calc

my ($y,$m,$d,$H,$M,$S) = Add_Delta_DHMS(Today_and_Now(),120,0,0,0);

I grasp a bit in Date:Calc documentation but I've not found a way to
convert the first in a delta vector, which I think it is the only way
Date:Calc could compare the the two dates.

How can I compare these two date type ?

Thanks

  FAQ 4.49 How do I process/modify each element of an array?

4.49: How do I process/modify each element of an array?

Use "for"/"foreach":

for (@lines) {
s/foo/bar/; # change that word
tr/XZ/ZX/; # swap those letters
}

Here's another; let's compute spherical volumes:

for (@volumes = @radii) { # @volumes has changed parts
$_ **= 3;
$_ *= (4/3) * 3.14159; # this will be constant folded
}

which can also be done with "map()" which is made to transform one list
into another:

  Use of Java script to validate form fields in Perl         


Author: Kuna
Date: Dec 27, 2006 01:06

Hi All,

I am trying to use Java script to validate the form fields. The code is
written in Perl and it is having a .pm extension for this form also
there is a index.pl file which is containing the "Save" button and the
form is posting the data to index.pl file and then it again comes to
the methods written in the .pm file which is validating the form using
server side code and submit that. But I am not able to get that where
to do the Java script validation that will validate the form in the
client side. Here I am having some codes that will give some idea about
my form.

  FAQ 4.68 How can I make the Perl equivalent of a C structure/C++ class/hash or array of hashes or arrays?

--------------------------------------------------------------------

4.68: How can I make the Perl equivalent of a C structure/C++ class/hash or array of hashes or arrays?

Usually a hash ref, perhaps like this:

$record = {
NAME => "Jason",
EMPNO => 132,
TITLE => "deputy peon",
AGE => 23,
SALARY => 37_000,
PALS => [ "Norbert", "Rhys", "Phineas"],
};

References are documented in perlref and the upcoming perlreftut.
Examples of complex data structures are given in perldsc and perllol.
Examples of structures and object-oriented classes are in perltoot.
