我正在使用bat script每天使用Windows中的任务计划程序自动备份数据库列表。但是，在运行脚本时，我遇到了错误。此时，脚本应该转储超过60个数据库，但只有前两个被转储。有关错误，请参阅下面的dumperrors.txt。任何帮助都是受欢迎和赞赏的。谢谢！
mysqlbackup.bat
:: FILE HISTORY ----------------------------------------------
:: UPDATE 11.7.2012 Added setup all folder paths into variables at the top of the script to ease deployment
:: UPDATE 7.16.2012 Added --routines, fix for dashes in filename, and fix for regional time settings
:: UPDATE 3.30.2012 Added error logging to help troubleshoot databases backup errors. --log-error="c:\MySQLBackups\backupfiles\dumperrors.txt"
:: UPDATE 12.29.2011 Added time bug fix and remote FTP options - Thanks to Kamil Tomas
:: UPDATE 5.09.2011 v 1.0
:: If the time is less than two digits insert a zero so there is no space to break the filename
:: If you have any regional date/time issues call this include: getdate.cmd credit: Simon Sheppard for this cmd - untested
:: call getdate.cmd

运行脚本后，我收到以下错误
dumperrors.txt
mysqldump: Couldn't execute 'SHOW FUNCTION STATUS WHERE Db = 'mysql'': Cannot load from mysql.proc. The table is probably corrupted (1728)
mysqldump: Got error: 1728: Cannot load from mysql.proc. The table is probably corrupted when using LOCK TABLES
答案 0 :(得分：0)
我建议每个错误报告覆盖errors文件。
尝试更改
--log-error=%errorLogPath%
到
--log-error=%errorLogPath%.%%F
请注意，此参数是后跟 %%F这是数据库名称。
此更改应为每个数据库创建一个单独的错误文件（如果有错误），并将数据库名称附加到.txt
