I have an application with highly compressable strings (gzip encoding
usually does somewhere between 20-50X reduction.) My base 350MB
database is mostly made up of these slowly (or even static) strings. I
would like to compress these so that my disk I/O and memory footprint
is greatly reduced.
Some databases have the ability to provide a compressed
table, compressed column, or provide a user defined function to
compress an indvidual...

Hi,
This is probably an easy question for someone so any help would be
appreciated.
I have changed the columns in a table that where nvarchar to the same
size of type varchar so halve the space needed for them.
I have done this a) becuase this is never going to be an international
application, b) we are running out of space and c) there are 100

Dear friends,
I studying the possibility to port Compiere CRM from Oracle to PostgreSQL. As
Compiere evolves nearly everyday in CVS, I would like to run the Oracle code
without (too much) modification.
Don't blame me, I know using search/replace works most of the times.
At first, I used CREATE TYPE syntax to map Oracle nvarchar2 to PostgreSQL
varchar type (see code #1). The code seems to be the equivalent of:

What is the best way to do this?
Binary with 0 representing off and 1 on?

Hi, I'm starting a new application in java using JTDS jdbc driver
(http://jtds.sourceforge.net) and SQLServer 2005 Express.
I have to design the database from scratch and my doubt is if I have to use
varchar or nvarchar fields to store string data.
Any experience about performance issues using nvarchar instead of varchar
(considering that Java internally works in unicode too)?
Thanks in advance,
Davide.

My collegue is saying that you should store text data in Sql Server i
unicode fields (nvarchar) beause that .net (asp.net website) is all
unicode and therefore you save some time not having to convert the data
from ascii to unicode.
So i thought that i should ask you experts what you saying about it?
What is best for performance if you do not have to store any unicode

Here i will show the differences between nvarchar and varchar:
The difference is that nvarchar is used to store unicode data, which is used to store multilingual data in the database tables. Other languages have an extended set of character codes that need to be saved and this datatype allows for this extension. If the database will not be storing multilingual data we should use the varchar database instead.
The reason for this is that...

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
Here is the code in...

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
