What happens if I try to delete many records and the database engine discovers, while deleting, that a record is locked by a user? For example, a table contains many thousands of records and 1000 of them meet a certain condition. I want to delete those records so I issue the command DELETE FOR that condition. After having deleted 800 of those 1000 records, the database engine encounters a record that is locked by a user. Does it automatically RECALL the 800 deleted records or do they remain deleted even though the command could not be completed successfully?
