apex中无法通过外部sql调用数据库过程（apex安全机制）

APEX的一种安全机制，在APEX之外运行其数据库内部的存储过程需要在过程中

调用APEX的API命令，否则就会报错

ORA-20001: This procedure must be invoked from within an application session.

要求必须从一个应用程序会话中调用，

要运行从SQL Developer或计划任务调度使用数据库，需要手动设置在执行Apex的API或访问数据的情况下安全组的命令

APEX中发送邮件：

begin

apex_mail.send(

p_to => 'to_user@their_company.com', -- change email address

p_from => 'your_email@company.com', -- change to your email address

p_body => 'Main email text goes here',

p_subj => 'APEX_MAIL Package - Plain Text message'

);

end;

首先获取工作区编号：

select workspace, schemas, workspace_id

from apex_workspaces;

然后修改为

begin

wwv_flow_api.set_security_group_id(workspace_id);

apex_mail.send(

p_to => 'to_user@their_company.com', -- change email address

p_from => 'your_email@company.com', -- change to your email address

p_body => 'Main email text goes here',

p_subj => 'APEX_MAIL Package - Plain Text message'

);

end;
