The following issues occur when an Access database is used in a process that frequently deletes and adds records:
1. The UPDATE statement may fail updating, either a record exists or select to, but the update failed error message when the record was not found with update.
2. Increase the database and reduce the efficiency of database operations
3. Deleting a record does not reduce the size of the database, and there is no corresponding statement to improve the database
Solutions
Download the Access database, open it with access software, work with the repair and Compress database tool, save and re-upload and overwrite the original database to resolve all of the above issues. This approach is only suitable for small and medium-sized databases, large if the use of the method is too slow to download.
