Question

我正在尝试为percona服务器上的数据库生成generateLog，当我尝试这样做时出现以下错误。

Starting Liquibase at Wed, 05 Dec 2018 22:34:37 EST (version 3.6.2 built at 
2018-07-03 11:28:09)
Unexpected error running Liquibase: liquibase.exception.DatabaseException:

    information for temporary table 'TMP_XDBOCVCKWHSQYXKP'

我正在尝试使用以下语句通过命令行使用它

liquibase --driver=com.mysql.cj.jdbc.Driver --classpath=C:/liquibase-3.6.2- 
bin/jars/mysql-connector-java-8.0.13.jar --changeLogFile=db.changelog- 
1.0.xml --url="jdbc:mysql://REMOTE_SERVER_IP:3306/DB_NAME? 
autoReconnect=true" --username=USER_NAME --password=PASSWORD --logLevel=info 
generateChangeLog

以前有人遇到过此问题吗？我尝试使用旧的和新的JDBC驱动程序，但没有帮助。

Answer 1

我遇到了同样的问题。设置logLevel进行调试，您可以看到Liquibase正在创建和删除临时表。那个临时表似乎引起了问题。

我能够通过使用MySQL Workbench将架构复制到常规MySQL实例，然后从那里运行generateChangeLog来解决此问题。
