Hello Dmity,
As suggested by Richard Huxton in this forum we can use any of the
"untrusted" procedural languages to access resources outside the database
(e.g. pl/perlu).
You can get the code to call the webservice from the postgresql function
from this url. http://www.pgsql.cz/index.php/PL/Perlu_-_Untrusted_Perl_(en)
Thanks,
Jyoti

Subject: Re: [OBORONA-SPAM] [SQL] calling webservice through postgresql
function
Good day, Jyoti.
JS> I want to call webservice from my postgresql database. Please let me
know if anyone has idea.
Idia or proper tool?
If idea, I offer to append some code into source of pg.
I already raised this question in topic
"We all are looped on Internet",
in which i read, that the most widespread transport protocol is HTTP,
and the most general format for data is XML (XHTML).
Idea is so: if we made
create table a ( id num primary key, data float
);
create table b ( id num primary key, ref num references a(id), data float
);
create table c ( id num primary key, link num references b(id), data float
);
insert into a values (1, 12.3);
insert into b values (10, 1, 23.4);
insert into b values (20, 1, 34.5);
insert into b values (30, 1, 45.6);
insert into c values (100,10,56.7);
insert into c values (101,10,67.8);
insert into c values (200,20,78.9);
insert into c values (201,20,89.1);
insert into c values (300,30,91.2);
we need simple request 'a.b.c' to get
<a id=1 data=12.3> <b id=10 data=23.4> <c id=100 data=56.7/> <c id=101 data=67.8/> </b> <b id=20
data=34.5> <c id=200 data=78.9/> <c id=201 data=89.1/> </b> <b id=30 data=45.6> <c id=200 data=91.2/> </b>
</a>
Request 'a.b.c' allow to avoid php,etc,
that is very necessary for unskilled users!
