Can't see the child table fields in the parent doctype from mariadb

I have created a doctype called “Multiple Tasks” and a child table in that doctype called “Tasks”. in the tasks table i have fields like name, title, priority, type and description. After creating a document in multiple tasks and adding values in the child table also when i see all the data in the mariadb. I can’t see the fields from the child table tasks. i have linked the child table to multiple tasks doctype also.

Child DocTypes have their own relations. Check table tabTasks

i can see the table in tabtasks but i want to create a new task on submitting the doctype multiple tasks under the project selected and i want to set the subject and project of the new task to be taken from tasks table and multiple tasks table.
