Description:

I've a function in Postgresql database. However, every time I run the
function in postgresql, it auto add character 's' behind of the query so it
will be error when execute (for example: WHAT IN HERE: query SELECT uom_id
FROM ps_quantity where id = 11s ). My version is Postgresql 9.2.13. How can
I solve this?

CREATE OR REPLACE FUNCTION select_field(
selected_table text,
selected_field text,
field_type_sample anyelement,
where_clause text DEFAULT ''::text)
RETURNS anyelement AS
$BODY$ DECLARE
-- Log
ME constant text := 'selected_field()';
-- Local variables
_qry varchar := '';
_result_value ALIAS FOR $0;
where_clause1 varchar := 'asdasdsad';
BEGIN
RAISE NOTICE 'FUNCTION: SELECT_FIELD';
-- BANGPH
RAISE NOTICE 'BANGPH - CHANGE 11s to 11';

_qry := 'SELECT uom_id FROM ps_quantity where id = 11';

RAISE NOTICE 'WHERE = %s', where_clause1;

RAISE NOTICE 'WHAT IN HERE: query %s', _qry;

You are mistaking the use of '%' and '%s'. When using RAISE NOTICE in
plpgsql you should just use '%' and not '%s' when assigning a variable
in a message. If you are willing to use %s, you can use format():
=# select format('string1: %s, string2: %s', 'titi', 'toto');
format
------------------------------
string1: titi, string2: toto
(1 row)
