In order to implement a fulltext search, I have a func that parses list
of words and creates a regexp query with things like [[::]]( word |
word | ... )[[::]]
That query then is passed to backend...
Now the strange thing:

I'm a little unclear on what you are trying to do here so I'll take a stab at
explaining how you can
Hello Bernardo,
there is a somewhat mathematical solution to your problem.
You can use a unique key, say 0= k MAX for each record,
and a second key which is computed from the first, say
f(k), which will give you a unique permutation of the
numbers 0,...,MAX-1. It will not be random, but it will

hey guys,
I am writing an article about using Perl inside sql commands.
I am not having a problem with perl, but with pl/pgsql.
The documentation for pl/pgsql isn't helping me out, although I am sure
I will figure it out eventually.
Here is the perl function,

Update to 7.1. 7.0.* has a lot of portability problems on Alphas,
and one of them is that regexps with between 33 and 64 states don't
work (int vs long problem...)

Mark,
I'd love to help you with your PL/pgSQL function, but since I don't
read Perl, I can't tell what you're trying to do. Can you spell it out
more explicitly?

What gives you the idea
Folks,
In 7.1 RC2, I've been trying to use the following JOIN syntax:
UPDATE assignments SET status = -1
FROM assignments JOIN orders ON assignments.order_usq = orders.usq
WHERE orders.status = -1;
However, I get an error of Relation assignments referenced twice in
query.
Hi!
How I can return random N rows from my select stmt?
like:
e.g. what my selectee is a set of 1000 rows, I want randomly
pickup 100 of 1000.
use the LIMIT clause
example
SELECT * FROM test_table LIMIT 100;
you can also use the OFFSET clause to skip to n row and the fetch the n
desired
Is it posible to make a rule execute more then one query?
Something like:
CREATE RULE rule_name AS ON INSERT TO table1
DO INSTEAD
INSERT INTO table2 VALUES
(new.value1,new.value2)
INSERT INTO table3 VALUES
(x,y)
If not, is there a way to do this? Triggers maybe?
Saludos... :-)

Interesting problem.
You might get much better responses than this, but, two ideas
that might be workable:

I think the proiblem is in trnsalte, not in regexp
If you have installed apprporiate character encoding in Postgres,
'upper' will work!

Thanks for the advice,
Hi folks,
I want to do the following: I have a column in every table, named c_update, it's
purpose is to hold how many times the dataset was updated. This should be done
automatically by the trigger - which already set sthe update-user, -time and date.
How can I do this ???

Hate to be entirely off topic, but can anyone help me with changing to digest version
