如何在 mysqldump 中的表名中转义 -

如果我想排除包含减号的架构中的表-，我该如何在 mysqldump 中转义该表？还是我不需要？

mysqldump --ignore-table=foo-bar.tl_log

似乎不起作用

答案1

每MySQL :: MySQL 5.7 参考手册 :: 5.5.4 mysqldump — 数据库备份程序

请尝试以下操作：

mysqldump --ignore-table=database.table1

答案2

不需要特殊转义：

答案3

通常，您会-用引号来转义连字符，因此我希望以下内容能够起作用：

mysqldump --ignore-table='foo-bar.tl_log'
