Thread: Error: "remote query result rowtype does not match the specified FROMclause rowtype," on remote function call
Error: "remote query result rowtype does not match the specified FROMclause rowtype," on remote function call
From
Antonio Gomez
Date:
This is my remote function:
CREATE OR REPLACE FUNCTION public._test1()
RETURNS record
LANGUAGE plpgsql
AS $function$
DECLARE
rec record;
BEGIN
select 1,2 into rec;
return rec;
END $function$;
This is my local function call:
SELECT x.a, x.b
FROM dblink('conn_str', 'select public._test1();')
as x(a int ,b int);
This is the error thrown:
ERROR: remote query result rowtype does not match the specified FROM clause rowtype
Question:
Since DBLINK requires that I define a schema to place the function's return items, how do I make the call to recognize a record type being returned by the function.
Thanks!

Do not have time to spin a test up at the moment, but what happens if
you do?"
SELECT *
FROM dblink('conn_str', 'select public._test1();')
as x(a int ,b int);

I figured it out, you have to specify the type twice, once inside the remote call and once outside.
Like this:
SELECT * FROM dblink('conn_str', 'select public._test1() as x(a int ,b int)') as x(a int ,b int);
Not optimal and not readily discernible, but there it is.
Thanks for your response!

Actually it sort of is, once I started working on a test:
select * from public._test1();
ERROR: a column definition list is required for functions returning
"record"
LINE 1: select * from public._test1();
