Hello everyone.
I have been using PostgreSQL for about 3-4 years now, it's wonderful how
I can make it do things and write Perl programs to interface with it.
Since I do all of the DBA behind the scenes on our company Intranet
(Linux-Apache based), and I really prefer writing Perl programs to do my
simple admin functions. I really like those \d commands (via telnet) and
they tell me a lot of what I need for writing new programs etc, but I
would really like a way to use those through my Perl programs, but
haven't found a way to do so, has anyone done this in this manner yet?
Also, I'd like a way to query a table to find out how much space it is
using, like it's percentage for example, is there a way to do that?
Excuse me if these questions have been asked before, I tried to search
the LIST area and I also did not see anything related to this in the FAQS.
Thanks for any info you can provide me.

TIP 8: explain analyze is your friend 1  1449 
you can retrieve any information of tables by queryng the catalog of
your database. For example, to get a description of table "sales", you
can query:
SELECT
C.relname, A.attname, T.typname
FROM
pg_class C
INNER JOIN pg_attribute A ON(C.oid=A.attr elid)
INNER JOIN pg_type T ON (T.oid=A.atttyp id)
WHERE
C.relname='sale s';
from perl, php, c or whatever.
Here ( http://www.postgresql.org/docs/7.3/i.../catalogs.html) is
the catalog tables documentation.
About your second question, you need to install contrb/dbsize. Then you
can query
SELECT relation_size(' sales');
to get the size of your sales table.

Hi,
Does anybody know what the fastest way is to "search for a value in a
singly-linked list from its tail" as oposed to its head?
I am talking about a non-circular singly-linked list, i.e., head and tail
are not connected.
Of course, recursive function aproach to traverse the list is one way. But,
depending upon the list size, it could overrun the stack pretty fast.

Hi
The question why are there no sorted dictionaries in python, seems to
pop up with unseeming regularity. That question in itself in
nonsensical sense dictionaries are hash-maps, however should python
have a sorted map type object is a good question.
clearly many people like have a sorted map, and sorting the keys every
time seems rather wasteful, as does keeping a separate sorted list of
the keys.

Hi
Quick question, that will point me in the right direction. I have 2
user controls on a page, both called List.ascx but obviously in 2
different namespaces and 2 different tags.. however I get the error:
Compiler Error Message: CS1595: 'ASP.List_ascx' is defined in multiple
places; using definition from
'c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET

I'm creating an unordered list that fits in a defined width on the left

Here is a watered-down version of the code:

If List.Listcount > 0 then
For intI = 0 to List.Listcount - 1

For some reason, and not all the time, this loop only runs to the second last entry. I have even witnessed it in break mode and following it step by step with Shift + F8, where it reports - for example - that the listcount is 14, when if fact it is 15 and has index values of 0 to 14. I made a quick fix, but I don't like...

Howdy, a (possibly) quick question for anyone willing to listen.
I have a question regarding lists and Classes; I have a class called
"gazelle" with several attributes (color, position, etc.) and I need
to create a herd of them. I want to simulate motion of individual
gazelles, but I don't want to have to go through and manually update
the position for every gazelle (there could be upwards of 50). I was
planning to create an array of these...

Hello, Newsgroupians:
Just a quick question really quick. Does C# have a generic class that will
allow me to add only one instance of an object to the "collection" without
having me do a .Contains() or something similar?
In my case, I have a set of controls a user selects. If the user selects
the same control twice, I don't want it added again to my collection, and I
don't want to handle the exception, and I think .Contains() is too...

vector - holds data in a contiguous memory block that has the same memory footprint as a classical array.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
