“The transaction log for database ‘database_name’ is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases.”
You may receive this error when you perform an operation on your database. This error occurs because there is not enough space in your Transaction Log file, so you cannot save the transaction to the Transaction Log file.
Make sure your Transaction Log file is large enough to handle the process you’re doing.
