Thread: plpgsql-function with timestamp
Hello out there,
Im a postgreSQL-newbie and I jaust want to create a "plpgsql-function" for
writing into a table.
The table is here:
CREATE TABLE auktionen(
aid SERIAL PRIMARY KEY,
kid INTEGER NOT NULL,
name VARCHAR(25) NOT NULL,
frei CHAR(1) DEFAULT 'Y',
status CHAR(1) DEFAULT '1', -- 1: In Vorbereitung
sofort NUMERIC(16,2) DEFAULT 0,
foto VARCHAR(25),
beschreibung VARCHAR(150),
startzeit TIMESTAMP NOT NULL,
endzeit TIMESTAMP NOT NULL,
startpreis NUMERIC(16,2) DEFAULT 0,
preis NUMERIC(16,2) DEFAULT 0,
katid INTEGER NOT NULL,
FOREIGN KEY(katid)
REFERENCES kategorie(katid),
FOREIGN KEY(kid)
REFERENCES kunden(kid)
);
And the function is here:
CREATE OR REPLACE FUNCTION neue_auktion ( numeric, text, text, TIMESTAMP,
TIMESTAMP, numeric, numeric, numeric ) RETURNS text AS $$
DECLARE
my_kunden_id ALIAS FOR $1;
my_name ALIAS FOR $2;
my_beschreibung ALIAS FOR $3;
my_startzeit ALIAS FOR $4;
my_endzeit ALIAS FOR $5;
my_startpreis ALIAS FOR $6;
my_preis ALIAS FOR $7;
my_kategorie ALIAS FOR $8;
BEGIN
INSERT INTO auktionen ( kid, name, beschreibung, startzeit, endzeit,
startpreis, preis, katid ) VALUES ( my_kunden_id, my_name, my_beschreibung,
my_startzeit, my_endzeit, my_startpreis, my_startpreis, my_kategorie );
RETURN 'OK';
END;
$$
LANGUAGE plpgsql;
But when I call this function, I get this dump:
test2=# SELECT neue_auktion ( 1, 'robot', 'robot', '1999-01-08 04:05:06',
'1999-01-08 04:05:06', 10, '10', '1');
FEHLER: Spalte »startzeit« hat Typ timestamp without time zone, aber der
Ausdruck hat Typ text
HINT: Sie müssen den Ausdruck umschreiben oder eine Typumwandlung
vornehmen.
CONTEXT: SQL-Anweisung »INSERT INTO auktionen ( kid, name, beschreibung,
startzeit, endzeit, startpreis, preis, katid ) VALUES ( $1 , $2 , $3 ,
$4 , $5 , $6 , $7 , $8 )«
PL/pgSQL function "neue_auktion" line 13 at SQL statement
Its in german and means: column >>startzeit<< has typ timestamp without time
zone, but the expression has text. But I have to put it in with quotes,
otherwise I get some syntax-errors!
What can I do here?
Gruss Christian

Which version?
test=# create table foo (ts timestamp);
CREATE TABLE
test=# insert into foo values ('1999-01-08 04:05:06');
INSERT 0 1
test=# CREATE OR REPLACE FUNCTION neue_auktion (TIMESTAMP) returns text
AS $$ DECLARE my_startzeit ALIAS FOR $1; BEGIN INSERT INTO foo (ts)
VALUES ( my_startzeit); RETURN 'OK'; END; $$ LANGUAGE plpgsql;
CREATE FUNCTION
test=# SELECT neue_auktion ('1999-01-08 04:05:06');
neue_auktion
--------------
OK
(1 row)
test=# select version();
version

The problem is solfed: I called the function with this arguments: SELECT neue_auktion ( 1::numeric, 'robot'::text, 'robot'::text, '1999-01-08 04:05:06'::timestamp, '1999-01-08 04:05:06'::timestamp, 10::numeric, 10::numeric, 1::numeric); And this works.

Hello!
Does the :: do a data type conversion?
