Hi,
How can i find the number of days in the intersection of 2 date interval?
For example:
1st interval: (10.01.2007, 20.01.2007)
2nd interval: (13.01.2007, 21.01.2007)
The intersection dates are: 13,14,15,16,17,18,19, 20
The result is: 8
How can i find the result, 8 in an sql query without usi

Hello,
in our application we need to implement a constraint that enforces 'at
most N rows with this value', that is we have a table with 'flag' column
and for each value there should be at most 10 rows (for example, the
exact number does not matter).
I'm trying to implement a PL/pgSQL trigge

Hi,
Is there anyway to evaluate a variable in plpgsql, like eval on PHP?
Suppose the example:
my_var:=''some value!'';
a:=''my_var'';
b:= a;
I already tried b:=EXECUTE a; without luck!
Best regards,
Luís Sousa

I haven't tested this to remind myself for sure that it will work,
but I think you ought to be able to RIGHT

Maybe stashing a SELECT in front?

Thanks codeWarrior - you got me 99% there - I just needed to add the NULL
"trick" on the join w/ the contact_phone and contact_address tables and that
got me the results I was after!
This is what I the final qry looks like :
SELECT
A.account_id,
A.account_username,
V.vendor_contract_signed_date,

Hi,
Is it possible to return rows from a function written in plpythonu using
SETOF?
Example:
CREATE FUNCTION "test_python_setof"()
RETURNS SETOF text AS '
records=plpy.execute("SELECT name FROM interface");
return records
' LANGUAGE 'plpythonu';
With this code is returning the object fr

I'm logging in directly on the machine. The installation gets most of

altering permissions, but the PostgreSQL installer creates new
accounts regardless with just user permissions. It's a mystery. Hmmm..
