Question

When a user creates an application for the table 'application' I want a copy placed into the table 'application_history'. I've tried creating a trigger and get the error that is in the title.

create or replace TRIGGER create_history AFTER INSERT ON application
FOR EACH ROW
DECLARE
BEGIN
insert into application_history values (:new.arn, :new.srn, :new.job_id, :new.application_status);
END;

Any help will be much appreciated.

Answer 1

我认为你最后需要一个/。所以：

create or replace TRIGGER create_history AFTER INSERT ON application
FOR EACH ROW
DECLARE
BEGIN
insert into application_history values (:new.arn, :new.srn, :new.job_id, :new.application_status);
END;
/

正如贾斯汀所怀疑的那样，你似乎在application_history中拥有超过4列。为所有列提供值或指定列，并插入table1（col1，col2）值（1,2）＆＃39;

在添加了额外的列＆＃39; hist_id＆＃39;之后，它对我有用（只是为了给你一个想法）......

create table application (arn number, srn number, job_id number, application_status char(1) );

create table application_history (hist_id number, arn number, srn number, job_id number, application_status char(1) );

create or replace TRIGGER create_application_history AFTER INSERT ON application
FOR EACH ROW
DECLARE
BEGIN
  insert into application_history values (1, :new.arn, :new.srn, :new.job_id, :new.application_status);
END;
/

SQL - Trigger is invalid and failed re-validation
