Well, if you can’t drop the records from the web interface, then you can delete the datacache entirely.

1. If you can afford a little downtime, then disable your database connection. If not, then disable the disk cache in store and forward settings for the database.
2. Navigate to `${ignitionInstallDirectory}/data/datacache/` and delete the _entire folder_ with the name of your database connection.
3. Re-enable the DB connection or disk cache. A new disk cache should be automatically generated.
