Webform data tables name change d7 to d8 tables to delete records from I have converted my d7 webforms to d8 with custom modules ... looks great
Previously I pulled data down from the database daily and deleted records from the webform_submissions and webform_submitted_data tables. (worked flawlessly for years)
With d8 the names are webform_submission and webform_submission_data.
Does anyone know if deleting the records from these two tables affects any other tables?  I intend to do as before... read daily, delete daily.
Thank you
I agree that you should use the 'Entity API' but if you are deleting 1000's of records I understand why you would want to do it using SQL.

Below are all the tables that are used to store webform submission related data.


webform_scheduled_email
webform_submission
webform_submission_data       
webform_submission_log
