pg 8.0.3
This behaviour seems odd to me:
CREATE TABLE mytable ( inta INTEGER
);
CREATE OR REPLACE FUNCTION myfunction (inta integer) RETURNS integer
AS
$body$
begin insert into mytable(inta) values (inta); return(0);
end;
$body$
LANGUAGE 'plpgsql';
select myfunction(123);
ERROR: syntax error at or near "$1" at character 22
QUERY: insert into myTable( $1 ) values ( $2 )
CONTEXT: PL/pgSQL function "myfunction" line 2 at SQL statement
The problem is with the line in my myfunction: insert into mytable(inta) values (inta);
The server doesn't like the field name being the same as the name of
the function parameter. I don't see why, as I can see no opportunity
for ambiguity.
Problem vanishes with a different function parameter name:
CREATE OR REPLACE FUNCTION myfunction (my_inta integer) RETURNS
integer
AS $body$ begin insert into myTable(inta) values (my_inta); return(0);
end;
$body$
LANGUAGE 'plpgsql'
But, this means that if I change the design of my tables, I have to
possibly change my function headers rather than merely the code inside
them.
