I made a mistake when importing a list of 1000 contacts using the import contacts tool. Unfortunately, I forgot to backup my database before importing the contacts.
All entries have the tag "casa" and the value "CASA" for a custom column "x_imi_data_import_identifier".
Is it safe for me to execute the SQL query "DELETE FROM res_partner WHERE x_imi_data_import_identifier=`casa`;"?
If not, what other queries can I execute? Or is there a way to delete contacts based on tags?
