MySQL dump file and commented out lines

阅读更多关于 MySQL dump file and commented out lines

问题 I have these lines at the top of a MySQL .sql file (dumped with phpMyAdmin): /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */; /*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */; /*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */; /*!40101 SET NAMES utf8 */; But they all seem to be commented out. So will MySQL ignore them when the file is loaded back into a database? If so, why generate these lines at all? 回答1: These are conditional comments aimed

On MySQL import: ERROR at line 32769: Unknown command '\''

阅读更多关于 On MySQL import: ERROR at line 32769: Unknown command '\''

问题 I'm receiving the following error while trying to import my DB: ERROR at line 32769: Unknown command '\''. I've done some searching and found that this can be because the dump was not created with the --hex-blob command. Unfortunately, I don't have the opportunity to do that now as this was the last backup made prior to my host having an untimely raid/hardware failure. Is there anything I can do to get my DB imported? Update: Tried using --force and --max_allowed_packet=1000M when importing.

Does mysqldump handle binary data reliably?

阅读更多关于 Does mysqldump handle binary data reliably?

问题 I have some tables in MySQL 5.6 that contain large binary data in some fields. I want to know if I can trust dumps created by mysqldump and be sure that those binary fields will not be corrupted easily when transferring the dump files trough systems like FTP, SCP and such. Also, should I force such systems to treat the dump files as binary transfers instead of ascii? Thanks in advance for any comments! 回答1: No, it is not always reliable when you have binary blobs. In that case you MUST use

问题 I don't know much about MySQL at all. But I am trying to reverse engineer a MySQL database using Visio.
