触发器共同在oracle apex应用程序中工作

Question

我需要在apex应用程序中创建动态批准工作流，所以我为此创建了触发器。但是我需要结合这些/使逻辑动态。

触发器1将电子邮件发送给第一批准人以供批准。批准者登录批准后，设置p_it_issues.APPROVE_THIS ='Y'，下一个触发器将设置p_it_issues.approved = 1以表明它已通过第一级。第二个触发器也会向第二个批准者发送电子邮件通知。（下面提到的所有代码仅供参考）。但是，在此应用中，批准级别应该是动态的，一个部门可以有2个批准者，而另一个部门可以有3个批准者。到目前为止，我的逻辑是人力资源部有2个批准级别。因此，在第二次批准时，如果p_it_issues.approved = 2且与p_it_departments.approval_level（部门批准数）设置为= 2，则可以解决此问题。（这最后一个条件，我仍然可以将授权方案设置为仅在2匹配时才解决问题）。

但是由于批准级别的不同，这意味着我将不得不创建越来越多的触发器。有没有一种方法可以结合使用此方法，以便它可以根据每个部门的approving_level不断增加并从p_it_people.approver ='审批人1'...'Áprovern'发送审批？ HR有2个，因此它不会将其发送到p_it_people表中的2个批准者，并且“批准者”列分别设置为“批准者1”和“批准者2”？

为了更清楚起见，我提供了2个触发器和随后的表结构。

让我知道是否需要进一步澄清。我知道这似乎很长且乏味，但是任何帮助将不胜感激。

第一级触发触发器：

CREATE OR REPLACE EDITIONABLE TRIGGER  P_IT_ISSUES_AIU_Notify_Approver_1
AFTER 
insert on P_IT_ISSUES 
for each row 
FOLLOWS P_IT_ISSUES_AIU_EMAIL
declare
v_person_id number;
v_email varchar2(255);
v_dept_name varchar2(50);
begin
select p.person_id ,p.person_email,i.dept_name into v_person_id,v_email,v_Dept_name from p_it_people p,p_it_departments i 
where p.assigned_dept=i.dept_id and i.dept_id=:new.related_dept_id and p.approver='Approver 1'  ;

             APEX_MAIL.SEND( 
                 p_to => v_email, 
                 p_from => v_email, 
                 p_body =>  
                 'You have been assigned a new issue for first level approval.  ' ||chr(10)|| 
                 'The details are below. ' ||chr(10)|| 
                 chr(10)|| 
                 ' Department:'|| v_dept_name ||chr(10)|| 
                 ' Summary: '||:new.issue_summary ||chr(10)|| 
                 ' Status: '||:new.status ||chr(10)|| 
                 'Priority: '||nvl(:new.priority,'-'), 
                  p_subj => 'New Issue for First Level Approval'); 


end;

/

触发2，在第一个批准者设置p_it_issues.approve_this ='Y'时设置p_it_issues.approved = 1。

CREATE OR REPLACE EDITIONABLE TRIGGER  P_IT_ISSUES_AIU_Notify_Approver_2
BEFORE 
update on P_IT_ISSUES
for each row 
declare
v_person_id number;
v_email varchar2(255);
v_dept_name varchar2(50);

begin

if :new.APPROVE_THIS = 'Y'
 then :new.APPROVED :=1 ;
 end if;

select p.person_id ,p.person_email,i.dept_name into v_person_id,v_email,v_Dept_name from p_it_people p,p_it_departments i 
where p.assigned_dept=i.dept_id and i.dept_id=:new.related_dept_id and p.approver='Approver 2'  ;

             APEX_MAIL.SEND( 
                 p_to => v_email, 
                 p_from => v_email, 
                 p_body =>  
                 'You have been assigned a new issue for second level approval.  ' ||chr(10)|| 
                 'The details are below. ' ||chr(10)|| 
                 chr(10)|| 
                 ' Department:'|| v_dept_name ||chr(10)|| 
                 ' Summary: '||:new.issue_summary ||chr(10)|| 
                 ' Status: '||:new.status ||chr(10)|| 
                 'Priority: '||nvl(:new.priority,'-'), 
                  p_subj => 'New Issue for Second Level Approval'); 


end;
