Thread: PARAMETERS IN QUERIES
Where can I find information about how to use parameters in queries? For example, to define parameters in the WHERE clause to build dynamic SELECT's.
I have searched the documentation manual but I cannot find this specific topic.
Thanks in advance.

I Think that he's a talking about that Oracle like Query:
BEGIN;
A = 1;
select * from test where id = a;
a := a + 1;
select * from test where id = a;
COMMIT;
The way to do it in Postgres is using function.
