Re: Creating functions

Hi:

I tried the code you gave me and it didn't work. I got this error:
unterminated dollar-quoted string at or near "$$ insert into test(a)
values($1);"

To be more specfic, I need to create a function to insert a given string
into a text type field. I don't need to return anything. I'm also wondering
if you could attach some documentation on this subject. I have troubles with
the Internet account.

Thanks in advance

There are lots of examples in the docs, but here's a super simple one in
sql:

# create table test (a int);
# create function addone(x int) returns int as $$
# insert into test (a) values ($1); select $1;
$$ language sql;
# select addone(5);
 addone
--------
      5
(1 row)
# select * from test;
 a
---
 5
(1 row)
