You missed to put the keyword RETURNS.

I want re-use this custom function, then put argument of function is table name:
account_object_bank_account_setId()
account_object_belong_to_group_setId()
to
set_id( table_name )
argument sample: account_object_bank_account, account_object_belong_to_group.
How to do?
update your 2 triggers with set_id('table_name')
and use TG_ARGV[] to retrieve the parameter in the trigger function

CREATE OR REPLACE FUNCTION customerGetByLargestSpend()

ERROR: syntax error at end of input

Not sure why this is happening.Any help would be very appreciated. thanks
The function is defined to return a row set, but does not return anything.
The parser expects to find something that returns rows, eg a select statement.
For example:
CREATE OR REPLACE FUNCTION customerGetByLargestSpend()
RETURNS TABLE(
customerID INTEGER,
firstName VARCHAR(20),
Surname VARCHAR(40),
totalBookings BIGINT,
totalSpend Numeric
)
AS $$ SELECT .... $$

how to create function in PostgreSQL am using below code
create table sample(id int primary key)
create table sample2(id int primary key)
create view sampleall
As
select id from sample
union
select id from sample2
while creating below function for above tables
Create FUNCTION CheckFunction (ID INT)
RETURNS BIT AS
$$
BEGIN
IF EXISTS (SELECT 1 FROM sampleall WHERE id = #ID)
BEGIN
RETURN 1
END
RETURN 0
END
$$
LANGUAGE plpgsql;
CREATE TABLE sample3 (ID INT NOT NULL CONSTRAINT CHK_ID CHECK (dbo.CheckFunction(ID) = 1))
and getting below error
ERROR: syntax error at or near "BEGIN"
LINE 8: BEGIN
^
********** Error **********
ERROR: syntax error at or near "BEGIN"
SQL state: 42601
Character: 132
please help to solve the issue
As documented in the manual an IF requires a THEN. Additionally, parameters cannot be prefixed with a #. To avoid a name clash between a parameter name and a column name you should use a different name for the parameter. A common approach is to prefix parameters with p_
However your function is needlessly complex and can be simplified substantially if you return a proper boolean rather than a bit:
Create FUNCTION check_function (p_ID INT)
RETURNS boolean AS
$$
select exists (SELECT 1 FROM sampleall WHERE id = p_id);
$$
LANGUAGE sql;
Your check constraint can then be simplified to:
CREATE TABLE sample3 (ID INT NOT NULL CONSTRAINT CHK_ID CHECK (check_Function(ID));
I've these two tables (Encomenda and Informacaofaturacao) and I'm trying to create a trigger to insert a new line on Informacaofaturacao before insert on Encomenda and put the ID of new line of Informacaofaturacao on new line of Encomenda.
What am I doing wrong?
Thanks

Postgres doesn't accept a data modifying SQL statement (INSERT, UPDATE or DELETE) in assignment. The documentation states:
... the expression in such a statement is evaluated by means of an SQL SELECT command sent to the main database engine.
You should use this form of executing a query with a single-row result instead.
Also, INSERT command must have VALUES part, it can be: DEFAULT VALUES, VALUES(...) or query see the syntax in the documentation.
CREATE OR REPLACE FUNCTION insert_encomenda()
RETURNS TRIGGER
AS $$
BEGIN
INSERT INTO Informacaofaturacao(InformacaofaturacaoID)
VALUES(DEFAULT)
RETURNING InformacaofaturacaoID
INTO NEW.InformacaofaturacaoID;
RETURN NEW;
END $$ LANGUAGE plpgsql;
I want to store my old records in a table when something has changed. I tried to do it with this documentation. But i still get a error. The error is: relation serie doesn't exist.
The original table:
CREATE TABLE "Terra_nub_v1"."Serie"
(
uuid uuid NOT NULL, -- t.b.v. pakbon
serie_nr integer NOT NULL,
aantal_slijpplaten integer,
producent text,
locatie text,
klaar boolean,
onderzocht boolean,
gerapporteerd boolean,
opmerking text,
verwijzing_hoofdrapportage text,
verwijzing_overige_rapportages text,
onderzoeksgebied polygon,
CONSTRAINT "Serie_pkey" PRIMARY KEY (serie_nr)
)
The archive table:
CREATE TABLE "Terra_nub_v1".serie_history
(
uuid uuid NOT NULL,
serie_nr integer NOT NULL,
aantal_slijpplaten integer,
producent text,
locatie text,
klaar boolean,
onderzocht boolean,
gerapporteerd boolean,
opmerking text,
verwijzing_hoofdrapportage text,
verwijzing_overige_rapportages text,
onderzoeksgebied polygon,
datumtijd_wijziging timestamp without time zone,
aangepast_door text,
CONSTRAINT serie_history_pkey PRIMARY KEY (serie_nr)
)
I make the trigger function this way:
CREATE OR REPLACE FUNCTION "Terra_nub_v1".serie_history_trigger()
RETURNS trigger AS $BODY$
BEGIN
IF (TG_OP ='UPDATE') THEN
INSERT INTO Terra_nub_v1.serie_history SELECT OLD.*,NOW(), USER ;
RETURN OLD;
ELSEIF (TG_OP = 'DELETE') THEN
INSERT INTO Terra_nub_v1.serie_history SELECT OLD.*,NOW(), USER ;
RETURN OLD;
END IF;
RETURN NULL;
END;
$BODY$ LANGUAGE plpgsql VOLATILE;
Create Trigger serie_history_trigger
BEFORE UPDATE OR DELETE ON Terra_nub_v1.serie
FOR EACH ROW EXECUTE PROCEDURE process_emp_audit();
I m using postgres
