Purge out the Calendar

[katztrd]

Is there a way to purge out all the users calendar? Im not sure what happened but we upgraded to a new server and did the ical import for the users that had OX1 plugin and did a pst import for those that did not. Well we have 10 thousand duplicates spread across all users and just want to start over.
I tried deleting them out of the mysql DB using myphpadmin
#1451 - Cannot delete or update a parent row: a foreign key constraint fails (`oxdatabase_5`.`dateExternal`, CONSTRAINT `dateExternal_ibfk_1` FOREIGN KEY (`cid`, `objectId`) REFERENCES `prg_dates` (`cid`, `intfield01`))

Hi,

please do never try to delete anything via the database - it will introduce far more grave issues than you're trying to solve by that. A valid possibility to remove calendars would be searching for "*" and remove them via the UI or the API.
