Question

I am attempting to write a migration script (between 2 versions of a program) to populate the phppos_permissions_actions table.

The rule for populating is: “If the user has permission for the module (based on phppos_permissions), then they are granted all action permissions for that module. (Which can be looked up in phppos_module_actions)”.

I am trying to write a query or a set of queries that makes the following rule happen. Could someone guide me in the right direction? Below is my schema

mysql> describe phppos_modules;

Does

insert phppos_permissions_actions (module_id, person_id, action_id)
select distinct 
    phppos_permissions.module_id, phppos_permissions.person_id, action_id
from phppos_permissions
    inner join phppos_modules_actions on phppos_permissions.module_id = phppos_modules_actions.module_id
order by module_id, person_id

solve your problem?
