Question

I need to clean out some old data from my database tables. Below shows two tables, app_status and app_personal_details.

I have the following query to select all the records (applications) from the app_status table which have been created over 12 months from todays date

select status_id  
from dbo.app_status  
where submission_date <= dateadd(month, -12, getdate()) order by 1

I then want to delete all the records from the app_personal_details table where the application_id exists in the list of retrieved status_id above.

I hope this makes sense. I would like to know a quick way of deleting the data from both tables.

Thanks for your help.

delete from app_personal_details
where application_id in (
    select status_id

)
