Mr. Taves,
Am I correct in concluding that I can't return a record
set from a function?
For example, in MS SQL I would do:
create procedure foo as
select * from yada
I expected to be able to do the following in postgresql.
create function foo (integer) returns (integer) as '

Probably, but we don't support UNION in views before 7.1 :-(

Hi fellows,
I'm trying to the following query:
select * from areas where titulo ~ '+' or titulo ~ '*'
and the answer is:
ERROR: regcomp failed with error repetition-operator operand invalid
I have tried to escape the '+' and the '*' with a backslash, as
follows:

I believe you'll need two \ characters to escape the + or *.

Hi,
I need your help on something. I have to write a
trigger (in sybase) that does this: Everytime a record
gets updated it should update a column in that record
with the current date/time. I am able to do it for the
whole table, but how do I make sure the update happens
only for that record
select field from table
where field like '%\\%%' or field like '%*%';
select field from table
where field ~ '.*\\*.*' or ~ '.*%.*';

Hi,
I was reading through Bruce's on line . I found follwing bit unclear...
"Notice that each query uses ORDER BY . Although this clause is not required,
LIMIT without ORDER BY returns random rows from the query, which would be
useless. "
When I run a query several time I get the same results
e.g.
Try:
CREATE TABLE emp (
id int4 primary key,
empname text,
salary int4,
last_date datetime,
last_user name);
CREATE FUNCTION emp_stamp () RETURNS OPAQUE AS
BEGIN
update emp set last_date=''now''::timestamp where id=NEW.id;
RETURN NEW;
END;

My understanding:
because you return a subset instead of a single value,
so between 2 select ... limit ... queries.
if you delete a record(say song_id=947) then insert it again.
then results are different.
So for a multiple users db, you should use oder by when you use limit.

I don't think it is actually random. It just that the order is not defined
and other events may change the order. I believe that without an ORDER BY
or other clauses that cause an index to be used that the database tends to
return rows in the order stored on disk. This order tends to be
