Dear Postgres Support
I am experiencing unexpected behaviour on Postgres 9.0.4 using pl/pgsql
relating to selecting from a function that returns a ROWTYPE into a ROWTYPE
variable from within another function.
In the example below I :
1) Create a table, TESTTABLE and insert a row.
2) Create a function FN_TEST_GET_ROW that returns a row of ROWTYPE TESTTABLE
based on selection of a single row from TESTTABLE
3) Create a test harness in the form of a function TESTX that calls
FN_TEST_GET_ROW with ID=1
4) Call the test harness
The error shown below is returned unexpectedly
ERROR: invalid input syntax for integer: "(1,Fred)"
I would just expect the values (1, Fred) to be returned which is what
happens if I execute
SELECT fn_test_get_row(1);
directly.
See attached SQL file for all scripts.
Create table
============
CREATE TABLE testtable
(
id INTEGER,
name VARCHAR(10)
);
Add Data
========
INSERT INTO testtable (id, name) VALUES (1, 'Fred');
END;
$$ LANGUAGE plpgsql;
Create function
===============
CREATE OR REPLACE FUNCTION fn_test_get_row(a INTEGER)
RETURNS testtable AS $$
DECLARE
i_row testtable;
BEGIN
SELECT *
INTO i_row
FROM testtable
WHERE id = a;
-- Success
RETURN i_row;
END;
$$ LANGUAGE plpgsql;
Create test function
====================
CREATE OR REPLACE FUNCTION testx()
RETURNS testtable AS $$
DECLARE
i_row testtable;
BEGIN
SELECT fn_test_get_row(1)
INTO i_row;
-- Success
RETURN i_row;
Execute the test function
=========================
select testx();
Error returned
==============
ERROR: invalid input syntax for integer: "(1,Fred)"
CONTEXT: PL/pgSQL function "testx" line 8 at SQL statement
********** Error **********
ERROR: invalid input syntax for integer: "(1,Fred)"
SQL state: 22P02
Context: PL/pgSQL function "testx" line 8 at SQL statement
