Postgres ошибка "ERROR: INSERT имеет несколько целевых столбцов, чем выражения"

Question

У меня есть следующие таблицы:

CREATE TABLE public.participant_audit 
(
    participant_audit_id bigint NOT NULL DEFAULT nextval('participant_audit_participant_audit_id_seq'::regclass), 
    participant_id bigint, 
    shared_asset_id bigint NOT NULL, 
    asset_role_type character varying(200) NOT NULL, 
    user_external_ref_uuid uuid NOT NULL, 
    user_first_name character varying(200) NOT NULL, 
    user_last_name character varying(200) NOT NULL, 
    user_email_address character varying(200) NOT NULL, 
    deleted_timestamp timestamp(0) with time zone, 
    row_updated_timestamp timestamp(6) with time zone NOT NULL, 
    row_created_timestamp timestamp(6) with time zone NOT NULL, 
    row_created_by_db_user oid NOT NULL, 
    row_updated_by_db_user oid NOT NULL, 
    created_by_client uuid, 
    updated_by_client uuid, 
    CONSTRAINT participant_audit_pkey PRIMARY KEY (participant_audit_id) 
) 
WITH (
    OIDS=FALSE 
); 

CREATE TABLE public.participant 
(
    participant_id bigint NOT NULL DEFAULT nextval('participant_participant_id_seq'::regclass), 
    shared_asset_id bigint NOT NULL, 
    asset_role_type_id bigint NOT NULL, 
    user_external_ref_uuid uuid NOT NULL, 
    user_first_name character varying(200) NOT NULL, 
    user_last_name character varying(200) NOT NULL, 
    user_email_address character varying(200) NOT NULL, 
    deleted_timestamp timestamp(0) with time zone, 
    row_updated_timestamp timestamp(6) with time zone NOT NULL, 
    row_created_timestamp timestamp(6) with time zone NOT NULL, 
    row_created_by_db_user oid NOT NULL, 
    row_updated_by_db_user oid NOT NULL, 
    created_by_client uuid, 
    updated_by_client uuid, 
    CONSTRAINT participant_pkey PRIMARY KEY (participant_id), 
    CONSTRAINT participant_asset_role_type_id_fkey FOREIGN KEY (asset_role_type_id) 
     REFERENCES public.asset_role_type (asset_role_type_id) MATCH SIMPLE 
     ON UPDATE NO ACTION ON DELETE NO ACTION, 
    CONSTRAINT participant_shared_asset_id_fkey FOREIGN KEY (shared_asset_id) 
     REFERENCES public.shared_asset (shared_asset_id) MATCH SIMPLE 
     ON UPDATE NO ACTION ON DELETE NO ACTION 
) 
WITH (
    OIDS=FALSE 
); 

И следующий TRIGGER ФУНКЦИЯ:

-- DROP FUNCTION public.participant_audit(); 

CREATE OR REPLACE FUNCTION public.participant_audit() 
    RETURNS trigger AS 
$BODY$ 
    BEGIN 
     insert into participant_audit 
        (participant_audit_id, participant_id , shared_asset_id , asset_role_type , user_external_ref_uuid, 
         user_first_name , user_last_name , user_email_address , deleted_timestamp, row_updated_timestamp, 
         row_created_timestamp , row_created_by_db_user , row_updated_by_db_user , created_by_client, 
         updated_by_client 
        ) 
        select NEW.* ; 
        RETURN NEW; 
    END; 
$BODY$ 
    LANGUAGE plpgsql VOLATILE SECURITY DEFINER 
    COST 100; 

Когда я выполнить следующий INSERT

INSERT INTO participant (shared_asset_id,asset_role_type_id, 
    user_external_ref_uuid,user_first_name,user_last_name, 
    user_email_address,row_created_by_db_user, 
    row_updated_by_db_user,created_by_client,updated_by_client) 
VALUES (1, 1, 'c9d140ad-b0da-4a9d-a898-8719000c7b7b'::uuid , 'john', 'simpson', 'js@gmail.com', 1::oid,1::oid, '53ed670d-f680-4e81-b53d-59b3d487633f'::uuid, '53ed670d-f680-4e81-b53d-59b3d487633f'::uuid); 

Я получаю следующее сообщение об ошибке:

ERROR: INSERT has more target columns than expressions LINE 2: ...user , row_updated_by_db_user , created_by_client,updated_by... ^QUERY: insert into public.participant_audit (participant_audit_id, participant_id , shared_asset_id , asset_role_type , user_external_ref_uuid,user_first_name , user_last_name , user_email_address , deleted_timestamp, row_updated_timestamp,row_created_timestamp , row_created_by_db_user , row_updated_by_db_user , created_by_client,updated_by_client) select NEW.* CONTEXT: PL/pgSQL function participant_audit() line 3 at SQL statement

********** Error **********

Как исправить эту проблему?

Answer 1

Проблема в вашем триггере. Подсчитайте столбцы, которые вы пытаетесь вставить в таблицу аудита.

insert into participant_audit 
        (participant_audit_id, participant_id , shared_asset_id , asset_role_type , user_external_ref_uuid, 
         user_first_name , user_last_name , user_email_address , deleted_timestamp, row_updated_timestamp, 
         row_created_timestamp , row_created_by_db_user , row_updated_by_db_user , created_by_client, 
         updated_by_client 
        ) 
        select NEW.* ; 

Это довольно много, чем то, что содержится в NEW, потому что ваш оператор insert содержит только 10 столбцов. Я считаю, что некоторые из ваших столбцов могут принимать значения NULL. Передайте nulls явно в части SELECT вашего оператора внутри триггера.
